Choosing this model
Selection advice by Y-API. The checks below are suggested evaluations, not published test results.
Where to start
Use it as a candidate for converting interface requirements into components and tests. Include empty, loading, error and narrow-screen states rather than evaluating only an attractive default screenshot.
What to watch for
The Kimi product’s agent-swarm workflow is not an automatic feature of a Chat Completions response. Image forwarding and tool execution must be validated in the client you actually deploy.
Model specifications
These are OpenRouter model-level specifications, not a Y-API compatibility test. A particular route may accept fewer input formats, parameters or tokens. Verify the features you need with a small request; a successful text response does not validate vision or tool calling.

- $0.295
Illustrative token budget, not measured usage or a quote. Includes input and output; excludes separate media charges, cache discounts and retries. Include billed reasoning tokens in your output budget where applicable. Actual billing follows usage returned by the service.
$1 paid adds $10 of credit. Cash equivalent = credit consumed ÷ 10; this is not the model publisher’s list price.
| Model | Estimated credit consumed | Estimated cash equivalent |
|---|---|---|
| Kimi K2.6 | $2.95 | $0.295 |
| Kimi K3 | $10.50 | $1.05 |
| Qwen3.8 Flash | $0.45 | $0.045 |
Use the API
These minimal, text-only requests use the exact Y-API model ID. They do not demonstrate image, audio, video, file or tool support. The output limit also needs room for reasoning; an empty answer with finish_reason=length can mean the budget was exhausted.
A task to try
Design the states of a searchable model list: loading, no matches, failed refresh and success. State what happens to existing results when a refresh fails.
Set the TOKEN environment variable to a key from your console. Run this on your server or locally; never expose a key in browser code or a public repository.

JSONHow to evaluate the result
A failed refresh should not erase usable cached results. Check keyboard access, retry behavior and clear distinction between no results and data not yet loaded.
Before you choose
Should I choose K2.6 or K3 for frontend work?
Compare the same component task and visual acceptance checks. K3 has a larger published context; that alone does not determine whether a smaller UI task benefits from it.
Sources & scope
Technical facts come from the cited model page and, where available, its linked publisher card. A card describes that checkpoint; it is not proof of the weights a gateway serves. Prices come only from the Y-API catalog. We do not claim measured latency, uptime or benchmark scores for this endpoint.
