GPT-5.6 Sol

OpenAI's flagship reasoning model with a 1M token context window, built for complex reasoning, coding, and multi-step problem-solving tasks.

Strengths

Excels at multi-step reasoning, code generation, and agentic workflows including command-line and scripting tasks.

Best for

Complex problem-solving, production code generation, agentic applications, and long-context reasoning tasks.

Limitations

The extended context window and advanced reasoning capabilities make it less efficient for simple or latency-sensitive tasks where a smaller model would suffice.
