FireRouter with Opus
This former Opus router is no longer available. Fireworks now documents Nexus Auto for model selection, or a specific model ID to keep every turn on one model.
Released 2026-09-28 · First reviewed 2026-10-10 · Checked 2026-11-03.
We still need comparable independent tests. You can compare the confirmed features and limits below, but we cannot yet give this version an Agent Fit or Practical Value rating. Test it on your own tasks before switching; results for another version or thinking setting may not apply.
Previously documented features
Token prices measure the small pieces of text the model reads or produces. Capacity is the amount the service accepts in a request; check the limits below for any fallback to another model. A dash means the rate is unverified.
Exact provider API ID: firerouter/opus. Fireworks says firerouter, firerouter/opus and auto-instant are no longer available. The old custom route does not have a current guaranteed model mix.
Migrate to auto for routing, or pin a supported model ID. Recheck credentials, application behavior and billing before switching.
No current capacity is established for this removed route.
Historical route prices are not a current offer. Nexus Auto bills according to the model that serves each turn. Allow for retries and any tool fees. Models that think before answering may also charge for that work.

Test a current alternative
Give each model the same examples, tools and definition of success. Record correct outcomes, response time, retries and total cost. A cheaper token price does not guarantee a cheaper completed task.
