How to call it

Send openai/gpt-6.1-sol in the model field of a request to https://api.gtokens.io/api/v1/chat/completions from an OpenAI-compatible client. This model answers in that shape only and with text only: a request that declares tools or attaches an image is refused with 400, a streamed request receives the finished reply in one piece, and max_tokens does not cut the reply short. The reasoning effort is set with reasoning.effort.
