# cost_constraint_exceeded

> HTTP 400 — No provider meets the cost constraint.

## HTTP status

`400 invalid_request_error`

## Typical cause

The `max_cost_per_1m` constraint excludes all available providers for this model.

## Resolution

Raise the cost threshold, remove the cost constraint, or choose a cheaper model.
