OVERVIEW

Model overview

Ember-1 is a specialized reasoning model from Fireworks Research, built on Kimi K3. It is designed to make every token go further: it produces shorter reasoning traces, using roughly 40%...

The summary below is compiled from sources by an AI model, not our own testing. Verify selection decisions against original sources and your workload.

Key features

  • Specialized reasoning model built on Kimi K3 architecture
  • Optimized for token efficiency, producing ~40% shorter reasoning traces
  • Supports multimodal inputs (text and image) with text-only outputs

Limitations & considerations

Sources are insufficient to establish specific limitations. Verify task performance, latency, data policies, licensing and version lifecycle.

Frequently asked questions

What architecture is Ember-1 based on?

Ember-1 is built on the Kimi K3 architecture.

Does Ember-1 support image inputs?

Yes, Ember-1 accepts image as one of its input modalities.

What types of outputs does Ember-1 generate?

Ember-1 generates text-only outputs.

Do open weights permit free commercial use?

Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.

Are these real-time billing prices?

These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
