## Questions

### How much does the Ember-1 API cost?

Fireworks's published list rate for Ember-1 is $3.00 per 1M input tokens and $15 per 1M output tokens, with cached input at $0.30 per 1M tokens (checked 2026-10-05). The provider account you connect bills you at the rate on that account, so a negotiated rate replaces the list rate. INFRO adds 0% to model spend.

### Which providers serve Ember-1?

In INFRO's provider registry, Ember-1 can be served by Fireworks AI and OpenRouter. You connect your own account with any of them, and INFRO routes and fails over between the ones you connect.

### What is the Ember-1 model ID?

Request it from INFRO as "fireworks/ember-1". INFRO sends each provider its own id: Fireworks AI "accounts/fireworks/models/ember-1", OpenRouter "fireworks/ember-1".

### How do I call Ember-1 through an OpenAI-compatible API?

Point an OpenAI SDK, or any HTTP client, at https://api.infro.io/v1 with an INFRO gateway key and send model "fireworks/ember-1" to POST /v1/chat/completions. INFRO runs the request on a provider account you connected and returns the provider's response with an estimated cost.

### Does INFRO mark up Ember-1 usage?

No. Fireworks or the provider you connect bills model usage to your own account. INFRO charges a software subscription for routing, failover, observability, budgets and policy, and takes 0% of model spend.
