Why does this limit matter?
A large advertised family capability does not make every model ID or endpoint interchangeable.
This value is scoped to Model specific; a different plan, runtime, model, endpoint, region, or account can produce a different effective constraint.
What should you check?
- Confirm the exact model ID and count the full request plus reserved output tokens.
- Confirm the exact plan, model, runtime, endpoint, region, and account that serve the failing workload.
- Record the observed value, response headers or configuration, timestamp, and source without logging secrets.
Important caveats
- Media tokenization, tool content, system instructions, and generated output all affect the usable budget.
- Treat the official source and live account configuration as authoritative if they differ from this verified snapshot.
HyperObserve reports the documented platform constraint. Your application, SDK, gateway, provider, region, or account can impose a lower effective limit.
