Anthropic designed Claude Haiku 4.5 for conversational assistants, user service, collaborative coding and prototyping. The model is useful in a cycle where a person asks a question, receives a result and immediately clarifies the next step. According to Anthropic, this version is characterized by low response latency; the actual time depends on the task and application.
Haiku 4.5 is also intended to process large numbers of separate tasks. In an agentic workflow, it can be assigned a specific subtask and its result then passed to the rest of the system. Described uses include coding, reasoning and interface actions. Tool calls and computer control are possible when the application provides the model with the appropriate tools; a single text request does not give it access to a working environment.
For tasks with multiple logical steps, extended thinking is provided: the application explicitly enables reasoning and sets its budget through budget_tokens. When the method supports these settings, the manual budget_tokens budget must be at least 1024 tokens and less than max_tokens to leave room for the final answer. It guides the amount of analysis, while max_tokens limits all output. Haiku 4.5 uses this manual mode specifically: adaptive reasoning and depth control through effort are not supported for this version. Reasoning between successive tool calls is also not supported.
This distinction is useful when choosing a task. Ordinary mode is suited to direct conversation; enabling reasoning gives the model room to work through code or a complex question. The task's content still determines what information needs to be analyzed and how the result should be presented.
The model accepts text and images and returns text. The context window is 200 thousand tokens, and the maximum response is 64 thousand tokens. An image serves as material for analysis alongside the question: the model can explain visible content and connect it to the text prompt. Image input support does not mean that images can be created or edited.
The manufacturer's standard visual input formats are JPEG/PNG/GIF/WebP, using the first frame of an animation. For native analysis, the longer dimension is 1568 pixels, with 1568 visual tokens; larger images are downscaled before analysis. File and parameter support depends on the application's method.
For this version, Anthropic describes a concise, direct conversational style. It is useful to specify the desired level of detail, result format and task constraints beforehand. The reliable built-in knowledge cutoff is February 2025; information about later events must be supplied in the task material or obtained through tools available to the application. Some requests may be declined.
If the method provides sampling settings, temperature and top_p cannot both be set: one of these parameters is selected for this version.
Technical example in English
Answer a delivery question\n\nWrite a concise support reply using only these notes: order R17 left the warehouse Tuesday; the carrier estimates Friday delivery; the customer asks if Thursday is guaranteed. Explain the current estimate, answer the guarantee question directly and offer to check a new carrier update if one becomes available. Keep the reply under 80 words.A customer-ready reply under 80 words, preserving the order ID and delivery estimate.Check that the reply never guarantees Thursday or invents a tracking update.claude-haiku-4-5-20251001Claude Haiku 4.5 is designed for interactive assistants, user support, everyday information processing and work on code.

claude-haiku-4-5-20251001Claude Haiku 4.5 is designed for interactive assistants, user support, everyday information processing and work on code. Supports a separate reasoning mode for complex questions.
This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.
Anthropic designed Claude Haiku 4.5 for conversational assistants, user service, collaborative coding and prototyping. The model is useful in a cycle where a person asks a question, receives a result and immediately clarifies the next step. According to Anthropic, this version is characterized by low response latency; the actual time depends on the task and application.
Haiku 4.5 is also intended to process large numbers of separate tasks. In an agentic workflow, it can be assigned a specific subtask and its result then passed to the rest of the system. Described uses include coding, reasoning and interface actions. Tool calls and computer control are possible when the application provides the model with the appropriate tools; a single text request does not give it access to a working environment.
For tasks with multiple logical steps, extended thinking is provided: the application explicitly enables reasoning and sets its budget through budget_tokens. When the method supports these settings, the manual budget_tokens budget must be at least 1024 tokens and less than max_tokens to leave room for the final answer. It guides the amount of analysis, while max_tokens limits all output. Haiku 4.5 uses this manual mode specifically: adaptive reasoning and depth control through effort are not supported for this version. Reasoning between successive tool calls is also not supported.
This distinction is useful when choosing a task. Ordinary mode is suited to direct conversation; enabling reasoning gives the model room to work through code or a complex question. The task's content still determines what information needs to be analyzed and how the result should be presented.
The model accepts text and images and returns text. The context window is 200 thousand tokens, and the maximum response is 64 thousand tokens. An image serves as material for analysis alongside the question: the model can explain visible content and connect it to the text prompt. Image input support does not mean that images can be created or edited.
The manufacturer's standard visual input formats are JPEG/PNG/GIF/WebP, using the first frame of an animation. For native analysis, the longer dimension is 1568 pixels, with 1568 visual tokens; larger images are downscaled before analysis. File and parameter support depends on the application's method.
For this version, Anthropic describes a concise, direct conversational style. It is useful to specify the desired level of detail, result format and task constraints beforehand. The reliable built-in knowledge cutoff is February 2025; information about later events must be supplied in the task material or obtained through tools available to the application. Some requests may be declined.
If the method provides sampling settings, temperature and top_p cannot both be set: one of these parameters is selected for this version.

claude-haiku-4-5-20251001Claude Haiku 4.5 is designed for interactive assistants, user support, everyday information processing and work on code. Supports a separate reasoning mode for complex questions.
This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.
Anthropic designed Claude Haiku 4.5 for conversational assistants, user service, collaborative coding and prototyping. The model is useful in a cycle where a person asks a question, receives a result and immediately clarifies the next step. According to Anthropic, this version is characterized by low response latency; the actual time depends on the task and application.
Haiku 4.5 is also intended to process large numbers of separate tasks. In an agentic workflow, it can be assigned a specific subtask and its result then passed to the rest of the system. Described uses include coding, reasoning and interface actions. Tool calls and computer control are possible when the application provides the model with the appropriate tools; a single text request does not give it access to a working environment.
For tasks with multiple logical steps, extended thinking is provided: the application explicitly enables reasoning and sets its budget through budget_tokens. When the method supports these settings, the manual budget_tokens budget must be at least 1024 tokens and less than max_tokens to leave room for the final answer. It guides the amount of analysis, while max_tokens limits all output. Haiku 4.5 uses this manual mode specifically: adaptive reasoning and depth control through effort are not supported for this version. Reasoning between successive tool calls is also not supported.
This distinction is useful when choosing a task. Ordinary mode is suited to direct conversation; enabling reasoning gives the model room to work through code or a complex question. The task's content still determines what information needs to be analyzed and how the result should be presented.
The model accepts text and images and returns text. The context window is 200 thousand tokens, and the maximum response is 64 thousand tokens. An image serves as material for analysis alongside the question: the model can explain visible content and connect it to the text prompt. Image input support does not mean that images can be created or edited.
The manufacturer's standard visual input formats are JPEG/PNG/GIF/WebP, using the first frame of an animation. For native analysis, the longer dimension is 1568 pixels, with 1568 visual tokens; larger images are downscaled before analysis. File and parameter support depends on the application's method.
For this version, Anthropic describes a concise, direct conversational style. It is useful to specify the desired level of detail, result format and task constraints beforehand. The reliable built-in knowledge cutoff is February 2025; information about later events must be supplied in the task material or obtained through tools available to the application. Some requests may be declined.
If the method provides sampling settings, temperature and top_p cannot both be set: one of these parameters is selected for this version.

claude-haikuClaude Haiku 4.5 is designed for interactive assistants, user support, everyday information processing and work on code. Supports a separate reasoning mode for complex questions.
This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.
Anthropic designed Claude Haiku 4.5 for conversational assistants, user service, collaborative coding and prototyping. The model is useful in a cycle where a person asks a question, receives a result and immediately clarifies the next step. According to Anthropic, this version is characterized by low response latency; the actual time depends on the task and application.
Haiku 4.5 is also intended to process large numbers of separate tasks. In an agentic workflow, it can be assigned a specific subtask and its result then passed to the rest of the system. Described uses include coding, reasoning and interface actions. Tool calls and computer control are possible when the application provides the model with the appropriate tools; a single text request does not give it access to a working environment.
For tasks with multiple logical steps, extended thinking is provided: the application explicitly enables reasoning and sets its budget through budget_tokens. When the method supports these settings, the manual budget_tokens budget must be at least 1024 tokens and less than max_tokens to leave room for the final answer. It guides the amount of analysis, while max_tokens limits all output. Haiku 4.5 uses this manual mode specifically: adaptive reasoning and depth control through effort are not supported for this version. Reasoning between successive tool calls is also not supported.
This distinction is useful when choosing a task. Ordinary mode is suited to direct conversation; enabling reasoning gives the model room to work through code or a complex question. The task's content still determines what information needs to be analyzed and how the result should be presented.
The model accepts text and images and returns text. The context window is 200 thousand tokens, and the maximum response is 64 thousand tokens. An image serves as material for analysis alongside the question: the model can explain visible content and connect it to the text prompt. Image input support does not mean that images can be created or edited.
The manufacturer's standard visual input formats are JPEG/PNG/GIF/WebP, using the first frame of an animation. For native analysis, the longer dimension is 1568 pixels, with 1568 visual tokens; larger images are downscaled before analysis. File and parameter support depends on the application's method.
For this version, Anthropic describes a concise, direct conversational style. It is useful to specify the desired level of detail, result format and task constraints beforehand. The reliable built-in knowledge cutoff is February 2025; information about later events must be supplied in the task material or obtained through tools available to the application. Some requests may be declined.
If the method provides sampling settings, temperature and top_p cannot both be set: one of these parameters is selected for this version.

claude-haikuClaude Haiku 4.5 is designed for interactive assistants, user support, everyday information processing and work on code. Supports a separate reasoning mode for complex questions.
This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.
Anthropic designed Claude Haiku 4.5 for conversational assistants, user service, collaborative coding and prototyping. The model is useful in a cycle where a person asks a question, receives a result and immediately clarifies the next step. According to Anthropic, this version is characterized by low response latency; the actual time depends on the task and application.
Haiku 4.5 is also intended to process large numbers of separate tasks. In an agentic workflow, it can be assigned a specific subtask and its result then passed to the rest of the system. Described uses include coding, reasoning and interface actions. Tool calls and computer control are possible when the application provides the model with the appropriate tools; a single text request does not give it access to a working environment.
For tasks with multiple logical steps, extended thinking is provided: the application explicitly enables reasoning and sets its budget through budget_tokens. When the method supports these settings, the manual budget_tokens budget must be at least 1024 tokens and less than max_tokens to leave room for the final answer. It guides the amount of analysis, while max_tokens limits all output. Haiku 4.5 uses this manual mode specifically: adaptive reasoning and depth control through effort are not supported for this version. Reasoning between successive tool calls is also not supported.
This distinction is useful when choosing a task. Ordinary mode is suited to direct conversation; enabling reasoning gives the model room to work through code or a complex question. The task's content still determines what information needs to be analyzed and how the result should be presented.
The model accepts text and images and returns text. The context window is 200 thousand tokens, and the maximum response is 64 thousand tokens. An image serves as material for analysis alongside the question: the model can explain visible content and connect it to the text prompt. Image input support does not mean that images can be created or edited.
The manufacturer's standard visual input formats are JPEG/PNG/GIF/WebP, using the first frame of an animation. For native analysis, the longer dimension is 1568 pixels, with 1568 visual tokens; larger images are downscaled before analysis. File and parameter support depends on the application's method.
For this version, Anthropic describes a concise, direct conversational style. It is useful to specify the desired level of detail, result format and task constraints beforehand. The reliable built-in knowledge cutoff is February 2025; information about later events must be supplied in the task material or obtained through tools available to the application. Some requests may be declined.
If the method provides sampling settings, temperature and top_p cannot both be set: one of these parameters is selected for this version.

claude-haikuClaude Haiku 4.5 is designed for interactive assistants, user support, everyday information processing and work on code. Supports a separate reasoning mode for complex questions.
This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.
Anthropic designed Claude Haiku 4.5 for conversational assistants, user service, collaborative coding and prototyping. The model is useful in a cycle where a person asks a question, receives a result and immediately clarifies the next step. According to Anthropic, this version is characterized by low response latency; the actual time depends on the task and application.
Haiku 4.5 is also intended to process large numbers of separate tasks. In an agentic workflow, it can be assigned a specific subtask and its result then passed to the rest of the system. Described uses include coding, reasoning and interface actions. Tool calls and computer control are possible when the application provides the model with the appropriate tools; a single text request does not give it access to a working environment.
For tasks with multiple logical steps, extended thinking is provided: the application explicitly enables reasoning and sets its budget through budget_tokens. When the method supports these settings, the manual budget_tokens budget must be at least 1024 tokens and less than max_tokens to leave room for the final answer. It guides the amount of analysis, while max_tokens limits all output. Haiku 4.5 uses this manual mode specifically: adaptive reasoning and depth control through effort are not supported for this version. Reasoning between successive tool calls is also not supported.
This distinction is useful when choosing a task. Ordinary mode is suited to direct conversation; enabling reasoning gives the model room to work through code or a complex question. The task's content still determines what information needs to be analyzed and how the result should be presented.
The model accepts text and images and returns text. The context window is 200 thousand tokens, and the maximum response is 64 thousand tokens. An image serves as material for analysis alongside the question: the model can explain visible content and connect it to the text prompt. Image input support does not mean that images can be created or edited.
The manufacturer's standard visual input formats are JPEG/PNG/GIF/WebP, using the first frame of an animation. For native analysis, the longer dimension is 1568 pixels, with 1568 visual tokens; larger images are downscaled before analysis. File and parameter support depends on the application's method.
For this version, Anthropic describes a concise, direct conversational style. It is useful to specify the desired level of detail, result format and task constraints beforehand. The reliable built-in knowledge cutoff is February 2025; information about later events must be supplied in the task material or obtained through tools available to the application. Some requests may be declined.
If the method provides sampling settings, temperature and top_p cannot both be set: one of these parameters is selected for this version.

When the method supports these settings, the manual budget_tokens budget must be at least 1024 tokens and less than max_tokens to leave room for the final answer. It guides the amount of analysis, while max_tokens limits all output. Haiku 4.5 uses this manual mode specifically: adaptive reasoning and depth control through effort are not supported for this version. Reasoning between successive tool calls is also not supported.
This distinction is useful when choosing a task. Ordinary mode is suited to direct conversation; enabling reasoning gives the model room to work through code or a complex question. The task's content still determines what information needs to be analyzed and how the result should be presented.
The model accepts text and images and returns text. The context window is 200 thousand tokens, and the maximum response is 64 thousand tokens. An image serves as material for analysis alongside the question: the model can explain visible content and connect it to the text prompt. Image input support does not mean that images can be created or edited.
The manufacturer's standard visual input formats are JPEG/PNG/GIF/WebP, using the first frame of an animation. For native analysis, the longer dimension is 1568 pixels, with 1568 visual tokens; larger images are downscaled before analysis. File and parameter support depends on the application's method.
For this version, Anthropic describes a concise, direct conversational style. It is useful to specify the desired level of detail, result format and task constraints beforehand. The reliable built-in knowledge cutoff is February 2025; information about later events must be supplied in the task material or obtained through tools available to the application. Some requests may be declined.
If the method provides sampling settings, temperature and top_p cannot both be set: one of these parameters is selected for this version.

claude-haiku-latestClaude Haiku 4.5 is designed for interactive assistants, user support, everyday information processing and work on code. Supports a separate reasoning mode for complex questions.
This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.
Anthropic designed Claude Haiku 4.5 for conversational assistants, user service, collaborative coding and prototyping. The model is useful in a cycle where a person asks a question, receives a result and immediately clarifies the next step. According to Anthropic, this version is characterized by low response latency; the actual time depends on the task and application.
Haiku 4.5 is also intended to process large numbers of separate tasks. In an agentic workflow, it can be assigned a specific subtask and its result then passed to the rest of the system. Described uses include coding, reasoning and interface actions. Tool calls and computer control are possible when the application provides the model with the appropriate tools; a single text request does not give it access to a working environment.
For tasks with multiple logical steps, extended thinking is provided: the application explicitly enables reasoning and sets its budget through budget_tokens. When the method supports these settings, the manual budget_tokens budget must be at least 1024 tokens and less than max_tokens to leave room for the final answer. It guides the amount of analysis, while max_tokens limits all output. Haiku 4.5 uses this manual mode specifically: adaptive reasoning and depth control through effort are not supported for this version. Reasoning between successive tool calls is also not supported.
This distinction is useful when choosing a task. Ordinary mode is suited to direct conversation; enabling reasoning gives the model room to work through code or a complex question. The task's content still determines what information needs to be analyzed and how the result should be presented.
The model accepts text and images and returns text. The context window is 200 thousand tokens, and the maximum response is 64 thousand tokens. An image serves as material for analysis alongside the question: the model can explain visible content and connect it to the text prompt. Image input support does not mean that images can be created or edited.
The manufacturer's standard visual input formats are JPEG/PNG/GIF/WebP, using the first frame of an animation. For native analysis, the longer dimension is 1568 pixels, with 1568 visual tokens; larger images are downscaled before analysis. File and parameter support depends on the application's method.
For this version, Anthropic describes a concise, direct conversational style. It is useful to specify the desired level of detail, result format and task constraints beforehand. The reliable built-in knowledge cutoff is February 2025; information about later events must be supplied in the task material or obtained through tools available to the application. Some requests may be declined.

claude-haiku-latestClaude Haiku 4.5 is designed for interactive assistants, user support, everyday information processing and work on code. Supports a separate reasoning mode for complex questions.
This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.
Anthropic designed Claude Haiku 4.5 for conversational assistants, user service, collaborative coding and prototyping. The model is useful in a cycle where a person asks a question, receives a result and immediately clarifies the next step. According to Anthropic, this version is characterized by low response latency; the actual time depends on the task and application.
Haiku 4.5 is also intended to process large numbers of separate tasks. In an agentic workflow, it can be assigned a specific subtask and its result then passed to the rest of the system. Described uses include coding, reasoning and interface actions. Tool calls and computer control are possible when the application provides the model with the appropriate tools; a single text request does not give it access to a working environment.
For tasks with multiple logical steps, extended thinking is provided: the application explicitly enables reasoning and sets its budget through budget_tokens. When the method supports these settings, the manual budget_tokens budget must be at least 1024 tokens and less than max_tokens to leave room for the final answer. It guides the amount of analysis, while max_tokens limits all output. Haiku 4.5 uses this manual mode specifically: adaptive reasoning and depth control through effort are not supported for this version. Reasoning between successive tool calls is also not supported.
This distinction is useful when choosing a task. Ordinary mode is suited to direct conversation; enabling reasoning gives the model room to work through code or a complex question. The task's content still determines what information needs to be analyzed and how the result should be presented.
The model accepts text and images and returns text. The context window is 200 thousand tokens, and the maximum response is 64 thousand tokens. An image serves as material for analysis alongside the question: the model can explain visible content and connect it to the text prompt. Image input support does not mean that images can be created or edited.
The manufacturer's standard visual input formats are JPEG/PNG/GIF/WebP, using the first frame of an animation. For native analysis, the longer dimension is 1568 pixels, with 1568 visual tokens; larger images are downscaled before analysis. File and parameter support depends on the application's method.
For this version, Anthropic describes a concise, direct conversational style. It is useful to specify the desired level of detail, result format and task constraints beforehand. The reliable built-in knowledge cutoff is February 2025; information about later events must be supplied in the task material or obtained through tools available to the application. Some requests may be declined.
If the method provides sampling settings, temperature and top_p cannot both be set: one of these parameters is selected for this version.
