# gpt-6.1-sol
> Create GPT-6.1 Sol responses and chat completions through AnyFast.
Use the Responses API for tool calling with reasoning. AnyFast also accepted Chat Completions function calling at low effort; `none` and `minimal` reasoning effort are unsupported.
The Responses API returned `model: "gpt-6.1-sol"`; Chat Completions returned `model: "azure/gpt-6.1-sol"`. A request with `prompt_cache_options.ttl: "30m"` returned `prompt_cache_retention: "24h"`; effective retention was not verified.
