Day 0 support for GPT-6.1 Sol on LiteLLM

[misbahsy]

GPT-6.1 Sol is now supported on LiteLLM

Call gpt-6.1-sol through the LiteLLM AI Gateway with the request you already send, with spend tracking, rate limits, fallbacks and logging in one place.

Same price as GPT-6 Sol, cheaper cache - $2 / MTok input and $10 output, with cached input halved to $0.10. Per OpenAI, it matches GPT-6 Astra on DeepSWE v1.1 at roughly a fifth of the cost.

Worth checking before you route traffic to it:

OpenAI serves tool calling for this model on the Responses API only; LiteLLM bridges /chat/completions requests with tools to /v1/responses automatically. reasoning_effort none is not supported, so temperature is not available.

Get started, no redeploy needed:

Pricing landed in PR #43738. Reload your pricing in the UI under Models + Endpoints -> Price Data -> Reload Price Data (or POST /reload/model_cost_map as an admin), on any version v1.76.0 or newer.
