GPT-6 Sol is an OpenAI model specialized for complex software engineering and agent-based automation. Developers use it to manage large codebases, investigate regressions, and build workflows where the model needs to reason across multiple steps. It handles both text and image inputs, which helps when you need to review architecture diagrams alongside source code.
The model provides a massive 1.05M token context window. This allows it to hold an entire repository or a thick stack of documentation in active memory. This helps teams avoid the fragmentation that happens when you have to feed an AI small snippets of a project. Instead, you can provide the full context of a bug or a migration plan and get a response that considers all dependencies.
Key Features
- 1.05M token context window for large-scale data ingestion
- 128K output limit for generating long-form documentation or code blocks
- Six distinct effort levels to balance speed and reasoning depth
- Multimodal input support for both text files and visual screenshots
- Native support for agentic workflows through the Responses API
- Traceable reasoning paths to help humans verify logic before merging
- Integration with external tools to execute commands and read results
How to Use
- Select the gpt-6-sol model identifier in your API configuration
- Upload the relevant source files, architecture notes, and screenshots
- Define the specific task, such as fixing a regression or planning a migration
- Set the effort level based on how complex the reasoning needs to be
- Review the proposed plan and check for contradictions before execution
Use Cases
- Investigating a regression by feeding the model a failure report and source files
- Mapping out a database migration while checking for compatibility constraints
- Building an autonomous agent that uses custom tools to verify code patches
- Reviewing a large set of competing technical proposals to find contradictions

FAQ
What is GPT-6 Sol?
It is a specialized OpenAI model built for high-level coding tasks and multi-step agent workflows. It handles much larger amounts of data than standard models.
Is GPT-6 Sol free?
No, it is a commercial model accessed via API. You will pay based on the tokens processed and the effort level selected.
What is the context window size?
The model supports up to 1.05 million tokens in a single request. This is enough to include hundreds of source files or long technical manuals.
Can it see images?
Yes, GPT-6 Sol accepts images as input. You can provide screenshots of UI bugs or diagrams of system architecture to help it understand the task.
How does it differ from GPT-5.6 Sol?
While context limits are similar, GPT-6 Sol focuses on higher-quality reasoning for complex tasks. You should evaluate it based on the accuracy of its output rather than just context size.
Is it available on reAPI yet?
Access is currently listed as coming soon. You can prepare your evaluation tasks now, but the API endpoints are not yet active for public use.
