Example task: Replay a migration acceptance fixture
Assume 20,000 aggregate input tokens and 2,000 billable output tokens across all calls. No cache hit.
20,000 × $0.29 / 1M + 2,000 × $1.16 / 1M = $0.008120
If usage actually reports 15,000 of those input tokens as cached, replace that portion at the cached-input rate ($0.0058/1M): $0.003857. Cached tokens are part of total input, never added on top.
Illustrative calculation using the October 9, 2026 catalog snapshot, not a measured bill or promised task size. Live rates above may differ. Include every agent call and retry, repeated history and billable reasoning output; settle against actual usage and Console records.
Known limits and verification scope
- This is a compatibility alias for V4.1 Flash, not a separately benchmarked model. Check the price returned for this exact ID and keep usage records separate while migrating.
- Catalog context: 1,048,576 tokens. Input and requested output share the context budget; this is not a measured usable boundary.
- The context and capability flags describe the public catalog. They do not establish a particular tool workflow or a quality score.
- Start with one representative task. Check correctness, actual usage and response time before increasing traffic.
- This page has no recorded end-to-end tool validation for this model. The integration examples let you run and record your own check.
Verified parameters and open questions
| Parameter / protocol field | Evidence status |
|---|---|
model / messages | Request example only; not live-verified for this model |
tools / tool_calls / tool messages | Catalog lists tool calling; argument and result cycle unverified |
chat_template_kwargs.enable_thinking=false | Qwen-specific option; do not copy to this model |
stream / temperature / top_p / max_tokens / response_format / reasoning_effort | No verified values recorded for this exact model ID |
A catalog capability flag is not a tested parameter value. Omit optional controls until checked with your exact model ID; an HTTP 200 alone does not prove the option took effect.
