About the model
This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.
Gemini 3.8 Flash is intended for long software engineering tasks, agentic workflows and complex knowledge work. Google describes it as a development of Gemini 3.7 Flash, emphasizing processes in which a solution does not end with one answer: the model revisits material, uses tools and continues a sequence of steps.
Material that can be analyzed
Google specifies text, image, video, audio and PDF inputs. In Ailoot API's current catalogue, text methods declare text and images as input and text as output. Video, audio and PDF are not included in this input set. The input limit is 1,048,576 tokens, and output 65,536 tokens. It produces text results, including code and structured data. Image and audio creation are not capabilities of this particular version.
Reasoning and tools
Thinking levels of low, medium and high are supported. In Google's described base-model mode, the default level is medium. These values describe Google's base model; the mode and availability of control through Ailoot API depend on the selected method and model variant. minimal is not supported and causes an error. Configurable effort helps select a mode suited to a stage's complexity, although at high effort the model sometimes uses more tokens to complete a task.
Capabilities include function calling, code execution, structured responses and context caching. File search, search grounding, Google Maps and reading URL contents are available. Batch processing is supported. Computer interface control has preview status; it does not turn every way of accessing the model into full-featured computer control.
Purpose and limitations
The manufacturer highlights software engineering, agent tasks and complex information workflows. Long context allows extensive material to be supplied, and tool capabilities allow several connected stages to be organized. These characteristics describe the model's capabilities; specific options and input data depend on the supported calling method.
The version was published as stable in September 2026. Its declared knowledge cutoff is March 2026, but information in some areas may remain at January 2025 levels. Fabricated facts, delays and timeouts are possible. More reasoning does not rule out errors, and a low effort level does not promise a particular response time.
Practical task
Plan a safe field-renaming migration
Technical example in English
Plan a safe field-renaming migration
A service stores customer.full_name; old clients send full_name and new clients send display_name. Plan a gradual migration that keeps old clients working while storage changes. Provide stages, rollback conditions and integration tests for mixed clients. Assume no migration tools or live database access; return the design and test scenarios only.Expected result
A staged migration design with compatibility rules, rollback conditions and mixed-version test cases.Check the result
Each stage specifies which field is read and written, including behavior when both fields are supplied.Ailoot · Anthropic Messages POST /v1/messages gemini-3.8-flash-high
