GPT-6.1 Sol · Azure at a glance

GPT-6.1 Sol · Azure (model ID azure/gpt-6.1-sol) is a GPT-series text model on Router One. GPT-6.1 Sol · Azure is the Azure sales channel of the same base model as openai/gpt-6.1-sol: a separately priced product with an isolated routing pool — requests never fall back to the default channel, its rates and long-context tiers are its own, a plan quota that covers openai/gpt-6.1-sol does not cover it unless the live plan response lists the channel id, and the response model field and Dashboard → Logs carry the channel id. No Router One subscription plan includes GPT-6.1 Sol · Azure today; every call bills the wallet at its posted rate. GPT-6.1 Sol · Azure is priced in whole-request tiers. Request input ≤ 272,000 tokens: Input $1.50 / 1M tokens, Output $7.50 / 1M tokens, Cache write $1.875 / 1M tokens, Cached input $0.075 / 1M tokens; request input > 272,000 tokens: Input $3.00 / 1M tokens, Output $11.25 / 1M tokens, Cache write $3.75 / 1M tokens, Cached input $0.15 / 1M tokens. The total input tokens in each request select the tier; its rates apply to the whole request, not only tokens above the threshold. Context window: 1.05M tokens. Accepts text, image; returns text. Endpoints: POST /v1/chat/completions (OpenAI-compatible), POST /v1/responses (Responses API, the Codex CLI path).

GPT-6.1 Sol · Azure FAQ

How much does GPT-6.1 Sol · Azure cost on Router One?

GPT-6.1 Sol · Azure is priced in whole-request tiers. Request input ≤ 272,000 tokens: Input $1.50 / 1M tokens, Output $7.50 / 1M tokens, Cache write $1.875 / 1M tokens, Cached input $0.075 / 1M tokens; request input > 272,000 tokens: Input $3.00 / 1M tokens, Output $11.25 / 1M tokens, Cache write $3.75 / 1M tokens, Cached input $0.15 / 1M tokens. The total input tokens in each request select the tier; its rates apply to the whole request, not only tokens above the threshold.

Is GPT-6.1 Sol · Azure included in Router One subscriptions?

No Router One subscription plan includes GPT-6.1 Sol · Azure today; every call bills the wallet at its posted rate.

Which endpoints serve GPT-6.1 Sol · Azure?

GPT-6.1 Sol · Azure is served on 2 endpoints — POST /v1/chat/completions (OpenAI-compatible), POST /v1/responses (Responses API, the Codex CLI path). The same Router One API key works on each.

What is GPT-6.1 Sol · Azure's context window?

GPT-6.1 Sol · Azure accepts up to 1.05M tokens of context per request on Router One.

What does the azure/ prefix in azure/gpt-6.1-sol mean?

azure/ selects the Azure sales channel on Router One. GPT-6.1 Sol · Azure is the same base model as openai/gpt-6.1-sol, sold as a separate product: routing stays inside the Azure channel with no fallback to the default channel, the posted rates and tiers are the channel's own, a plan quota covers it only when the live plan response lists the channel id, and the channel id is echoed in the response and in every request trace. Router One publishes the channel label and the customer price, not the suppliers or regions behind it; the channel model ids guide on the blog states the full rules. No Router One subscription plan includes GPT-6.1 Sol · Azure today; every call bills the wallet at its posted rate.
