Point the OpenAI SDK at OSMEXO and use moonshot/kimi-k2.5
The base URL and the key are the only changes. Streaming, tool calls, structured output and vision behave as they do upstream, and every response carries the billed cost beside the list price.

Check it is the real Kimi K2.5, with your own key
The same battery we run before a route goes live: tokenizer fingerprint, knowledge cutoff, hidden-prompt probe and exact-output tasks, scored 0 to 100 against the vendor’s own API. One OpenRouter key verifies any text model; a direct Moonshot key works too. Exit code 0 means the same model.

- Is this the same Kimi K2.5 as calling Moonshot directly?
- Yes. Every route for Kimi K2.5 is probed against the vendor’s own API before it serves anyone: tokenizer fingerprint, knowledge cutoff, a hidden-prompt probe and exact-output tasks, scored 0 to 100 with 85 as the approval threshold. You can run the same check from your machine with your own vendor key; the command is on this page.
- How do I call Kimi K2.5 with the OpenAI SDK?
- Point the official OpenAI SDK at https://api.osmexo.com/v1 with your OSMEXO key and use the model id moonshot/kimi-k2.5. Streaming, tool calls, structured output and vision work as they do upstream. Coding agents such as OpenCode, Cline, Roo Code, Continue and Aider take the same base URL and key.
- What happens if a provider for Kimi K2.5 goes down?
- The gateway retries and falls back to the next verified route for Kimi K2.5 before the first token is sent, so your users see a slower answer instead of an error. Every response reports which route answered, what it cost, and what the same tokens would have cost at list price.
