GPT 5.6 Sol
GPT 5.6 Sol is a text generation model from OpenAI with a 1,050,000-token context window and image input support.
Large-context text generation with adjustable reasoning
GPT 5.6 Sol is a large language model developed by OpenAI, released in July 2026. It supports a context window of up to 1,050,000 tokens and can generate responses of up to 128,000 tokens, making it suited for tasks that involve long documents, extended conversations, or large codebases. The model also accepts image inputs alongside text, enabling multimodal workflows.
One of its distinguishing configuration options is an adjustable reasoning effort setting, which allows users to control how much computational reasoning the model applies before generating a response. This makes it adaptable to a range of use cases, from quick text generation tasks to more deliberate, multi-step reasoning problems. GPT 5.6 Sol is available as a first-party model on MindStudio without requiring separate API key configuration.
What GPT 5.6 Sol supports
Long Context Window
Processes up to 1,050,000 tokens in a single context, enabling analysis of very long documents, codebases, or conversation histories.
Large Response Output
Generates responses of up to 128,000 tokens, supporting detailed reports, long-form content, and extended code generation in a single call.
Image Input Support
Accepts images alongside text prompts, allowing the model to analyze, describe, or reason about visual content in a multimodal workflow.
Adjustable Reasoning Effort
Exposes a reasoning effort selector that lets users tune how much deliberate reasoning the model applies before responding, balancing speed against depth.
Text Generation
Produces natural language text for tasks such as summarization, drafting, question answering, and instruction following.

What is the context window size for GPT 5.6 Sol?
GPT 5.6 Sol supports a context window of 1,050,000 tokens, allowing very long documents or conversations to be processed in a single request.
What is the maximum response length?
The model can generate responses of up to 128,000 tokens per call.
Does GPT 5.6 Sol support image inputs?
Yes. The model accepts image inputs in addition to text, enabling multimodal use cases such as image description or visual question answering.
What does the reasoning effort setting do?
The reasoning effort input is a selectable parameter that controls how much deliberate reasoning the model performs before generating a response. Lower effort may produce faster responses, while higher effort is suited to complex or multi-step tasks.
When was GPT 5.6 Sol released and what is its knowledge cutoff?
GPT 5.6 Sol was released in July 2026. A specific training data cutoff date is not listed in the available metadata; consult OpenAI's official documentation for the most accurate information.
