Model overview

GPT-6.1 Sol for coding, reasoning, and professional work

Connect code, documents, and images in a deliberate reasoning workflow. The artwork illustrates these workflows; it is not image output from GPT-6.1 Sol.

GPT-6.1 Sol text generation model cover
01 · Text generation

Work through complex software tasks

Provide the relevant code, the expected behavior, and verification criteria. Ask for a focused implementation or review, then refine it using concrete results.

  • Send one required user prompt with optional system instructions.
  • Review the exact non-streaming API request before running it.
  • Inspect assistant text, finish reason, response ID, and token usage together.

Connect a large working context

Bring up to 1,050,000 context tokens into a connected analysis of documents and repositories. Identify the source material and separate confirmed facts from assumptions.

GPT-6.1 Sol: Reason across text and images
03 · API integration

Reason across text and images

Include screenshots, diagrams, or other images alongside a specific question. The model returns text that can explain visual evidence and connect it to your written context.

  • Compare enabled language models in one place.
  • Copy the request preview to keep application requests aligned with the Playground.
  • Handle assistant responses and provider availability states in the same workflow.

Model characteristics

Better for creative validation than isolated one-off generation.

01

Workflow focus

Coding, multi-step reasoning, and professional work with text and image inputs.

02

Context window

Up to 1,050,000 context tokens.

03

Maximum output

The model supports up to 128,000 output tokens, including reasoning.

04

Reasoning control

Reasoning stays enabled. Select low, medium, high, xhigh, max; medium is the default.

FAQ

These are the first questions to answer when evaluating this model.

What is GPT-6.1 Sol suited to?

Use it for coding, document analysis, visual reasoning, and complex professional tasks. State the goal, constraints, relevant evidence, and expected response structure.

Can I include images?

Yes. Attach images in the Playground or send native image blocks through Chat Completions or Responses. Responses are text; native image fields are forwarded for upstream validation.

How do I choose a reasoning level?

Select low, medium, high, xhigh, max. Reasoning stays enabled, with medium as the Playground default.

How much context and output can I use?

The model supports 1,050,000 context tokens and up to 128,000 output tokens. Input and generated reasoning share the available context with the final answer.

Which API formats are available?

Use model openai/gpt-6.1-sol through OpenAI-compatible Chat Completions or Responses. Use Responses for application tool workflows. Both protocols accept streaming and non-streaming requests.

How do I continue a Responses conversation?

Include previous response items in the next input. Preserve reasoning.encrypted_content unchanged with the conversation and application tool results.
