GPT-6 Sol
GPT-6 Sol is a coding and agent model that remains available alongside GPT-6.1 Sol. It accepts images and text and generates text.
Tool use depends on the endpoint and reasoning setting
Responses supports its built-in tools and function calls. Chat Completions function calling requires reasoning_effort to be none. EU residency is listed for Standard, Flex and Batch, but not Fast processing. These conditions differ from a simple model-name replacement.GPT-6 Sol official model documentation
Review the whole tool loop during migration
Practical guidance. Compare a source change from initial request through tool results to final review. Preserve the exact endpoint and reasoning setting in the record. A successful text reply does not prove that the application executes and returns function calls correctly.
