Claude Opus 4.6 is intended for work where it is useful to keep extensive material in one context and reason after reading it. Anthropic highlights development in large codebases, code review, debugging, financial analysis and research. The model can find important details, connect information from different parts of the material and use it to solve a task sequentially.
In development, this means working on a plan, studying an unfamiliar system and finding errors in changes. In professional analysis, it means processing documents and preparing the content of spreadsheets, reports or presentations. For these scenarios, the model needs the task itself and the material from which conclusions should be drawn, rather than just a general topic name.
The model supports adaptive mode: it determines from the prompt's content when additional analysis is useful. The effort parameter sets the level of work; Opus 4.6 supports low, medium, high and max, with high as the default. According to Anthropic, deeper analysis can increase response time on simple tasks, so the selected level should reflect their complexity.
Older extended thinking with a manual budget is still supported, but is marked as deprecated. This version has an important distinction between modes: reasoning between tool calls is available in adaptive mode, but Opus 4.6 does not perform it in manual mode. With tools connected, adaptive analysis helps use the result of one action to choose the next.
Anthropic's current specification provides 1 million tokens of context and up to 128 thousand response tokens in ordinary mode. It accepts text and images, with text as its response. The reliable built-in knowledge cutoff is May 2025.
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 extended conversations and agentic tasks, the manufacturer describes compaction of old context: earlier work is replaced by a summary as a specified threshold approaches. This capability is marked as experimental and requires application support; context size alone does not provide unlimited memory.
Opus 4.6 is designed for multi-step work with search, code and other available tools. The application environment must provide material reading, command execution or file production. Production actions, interface control and creation of a finished presentation depend on these tools; a text model does not receive them automatically.
Anthropic separately describes safety checks and protective measures for potentially dangerous cybersecurity tasks. For ordinary development, the model can help find and fix vulnerabilities, but the nature of a request affects whether it can answer. Conclusions drawn from a large body of material and proposed changes need to be checked against the actual data and execution results.

Use the method paths shown above.
claude-opus-4-6Claude Opus 4.6 is designed for large codebases, debugging, research and analysis of long documents. Supports adaptive reasoning and a context window of up to 1 million tokens.
This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.
Claude Opus 4.6 is intended for work where it is useful to keep extensive material in one context and reason after reading it. Anthropic highlights development in large codebases, code review, debugging, financial analysis and research. The model can find important details, connect information from different parts of the material and use it to solve a task sequentially.
In development, this means working on a plan, studying an unfamiliar system and finding errors in changes. In professional analysis, it means processing documents and preparing the content of spreadsheets, reports or presentations. For these scenarios, the model needs the task itself and the material from which conclusions should be drawn, rather than just a general topic name.
The model supports adaptive mode: it determines from the prompt's content when additional analysis is useful. The effort parameter sets the level of work; Opus 4.6 supports low, medium, high and max, with high as the default. According to Anthropic, deeper analysis can increase response time on simple tasks, so the selected level should reflect their complexity.
Older extended thinking with a manual budget is still supported, but is marked as deprecated. This version has an important distinction between modes: reasoning between tool calls is available in adaptive mode, but Opus 4.6 does not perform it in manual mode. With tools connected, adaptive analysis helps use the result of one action to choose the next.
Anthropic's current specification provides 1 million tokens of context and up to 128 thousand response tokens in ordinary mode. It accepts text and images, with text as its response. The reliable built-in knowledge cutoff is May 2025.
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 extended conversations and agentic tasks, the manufacturer describes compaction of old context: earlier work is replaced by a summary as a specified threshold approaches. This capability is marked as experimental and requires application support; context size alone does not provide unlimited memory.
Opus 4.6 is designed for multi-step work with search, code and other available tools. The application environment must provide material reading, command execution or file production. Production actions, interface control and creation of a finished presentation depend on these tools; a text model does not receive them automatically.
Anthropic separately describes safety checks and protective measures for potentially dangerous cybersecurity tasks. For ordinary development, the model can help find and fix vulnerabilities, but the nature of a request affects whether it can answer. Conclusions drawn from a large body of material and proposed changes need to be checked against the actual data and execution results.

Ailoot claude-opus-4-6
Use the method paths shown above.
claude-opus-4-6Claude Opus 4.6 is designed for large codebases, debugging, research and analysis of long documents. Supports adaptive reasoning and a context window of up to 1 million tokens.
This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.
Claude Opus 4.6 is intended for work where it is useful to keep extensive material in one context and reason after reading it. Anthropic highlights development in large codebases, code review, debugging, financial analysis and research. The model can find important details, connect information from different parts of the material and use it to solve a task sequentially.
In development, this means working on a plan, studying an unfamiliar system and finding errors in changes. In professional analysis, it means processing documents and preparing the content of spreadsheets, reports or presentations. For these scenarios, the model needs the task itself and the material from which conclusions should be drawn, rather than just a general topic name.
The model supports adaptive mode: it determines from the prompt's content when additional analysis is useful. The effort parameter sets the level of work; Opus 4.6 supports low, medium, high and max, with high as the default. According to Anthropic, deeper analysis can increase response time on simple tasks, so the selected level should reflect their complexity.
Older extended thinking with a manual budget is still supported, but is marked as deprecated. This version has an important distinction between modes: reasoning between tool calls is available in adaptive mode, but Opus 4.6 does not perform it in manual mode. With tools connected, adaptive analysis helps use the result of one action to choose the next.
Anthropic's current specification provides 1 million tokens of context and up to 128 thousand response tokens in ordinary mode. It accepts text and images, with text as its response. The reliable built-in knowledge cutoff is May 2025.
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 extended conversations and agentic tasks, the manufacturer describes compaction of old context: earlier work is replaced by a summary as a specified threshold approaches. This capability is marked as experimental and requires application support; context size alone does not provide unlimited memory.
Opus 4.6 is designed for multi-step work with search, code and other available tools. The application environment must provide material reading, command execution or file production. Production actions, interface control and creation of a finished presentation depend on these tools; a text model does not receive them automatically.
Anthropic separately describes safety checks and protective measures for potentially dangerous cybersecurity tasks. For ordinary development, the model can help find and fix vulnerabilities, but the nature of a request affects whether it can answer. Conclusions drawn from a large body of material and proposed changes need to be checked against the actual data and execution results.

Technical example in English
Trace a cache invalidation defect\n\nReview this change using the supplied contract. Contract: changing an account's role must affect the next permission check. Current flow: update_role writes the database; can_edit reads a role cache with a 15-minute TTL. Propose the smallest correction, explain the failure window, and give regression tests for a demotion and an unrelated account. Do not assume any framework.A code-review note containing cause, a targeted invalidation strategy and two regression-test specifications.A demoted account cannot retain edit permission until the cache expires, while another account's entry remains valid.
