Ember-1

fireworks/ember-1

Ember-1 is a specialized reasoning model from Fireworks Research, built on Kimi K3.

Key facts

Input price
$3.00 / 1M tokens
Output price
$15.00 / 1M tokens
Context window
1M tokens
Max output
944K tokens
Accepts
Text, Images
Returns
Text

Example: 1,000 requests with 1,000 input and 500 output tokens each would cost about $10.50 (1M input tokens × $3.00 + 0.5M output tokens × $15.00). Estimate your own usage.

Prices are the provider’s own per-token rates with zero markup, from our price list as of Oct 18, 2026. If a call has extra provider charges (images, audio, web search, cached prompts), you pay the reported cost.
