Thinking levels: max · high · low

Ember-1 is a reasoning model from Fireworks Research built on Kimi K3 and tuned to think in fewer tokens. Its reasoning traces are roughly 40% shorter than the base model's while quality stays comparable, which lowers both the bill and the wait on reasoning-heavy work. Reasoning effort can be set to low, high or max.

It accepts text and image input and returns text, and supports tool calling, structured JSON output and streaming. Reasoning can be switched on when a problem needs more thought and left off when speed matters. Ember-1 is commonly used for coding, knowledge work and agent workflows where reasoning cost and latency matter. Hormouz serves it behind an OpenAI-compatible API: point your base URL at Hormouz, drop in a Hormouz key, and existing OpenAI SDK code runs without changes.

Pricing is usage-based: $3 per million input tokens and $15 per million output tokens. There is no fixed monthly fee, and you pay only for the tokens you use. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
