# Ember-1 is on AI Gateway.

## Retrieval answer

Ember-1’s arrival on Vercel AI Gateway turns a model-efficiency claim into an operational choice for teams running coding agents.

Ember-1’s arrival on Vercel AI Gateway turns a model-efficiency claim into an operational choice for teams running coding agents.

Vercel says Fireworks’ Ember-1 is available on AI Gateway under the model identifier `fireworks/ember-1`, initially as a two-week research preview. The announcement describes Ember-1 as a reasoning model built on Kimi K3 for coding and agentic workflows. It also states that the model supports a 1M-token context window, text and image input, tool calling, and implicit prompt caching. Fireworks reports approximately 40% fewer generated tokens than Kimi K3 at comparable quality across its evaluations.

The mechanism is that lower token generation can reduce both output spend and the reasoning trace that a repeatedly calling agent carries into later steps. AI Gateway makes that trade-off easier to test in an existing application because it presents a unified API and adds usage tracking, cost tracking, API-key budgets, and routing rules around the model endpoint. The possible benefit is therefore not simply a new model listing; it is a way to compare quality, latency, and token use within a controlled gateway layer.

Why now is that the model is newly accessible through Vercel’s gateway, while the initial preview window makes the decision time-sensitive for evaluators. For agent builders, the first implication is that a long-context, tool-capable coding model can be trialed alongside existing gateway-routed models without creating a separate provider integration. A second implication is that claimed token efficiency matters most where workflows make many sequential calls, rather than in a single isolated prompt.

The evidence boundary is that the 40% token reduction and comparable-quality claim comes from Fireworks’ own evaluations, and the announcement does not provide the underlying benchmark tasks, pricing, latency figures, or independent replication. The first watch condition is whether Vercel or Fireworks publishes pricing, rate limits, benchmark methodology, and production-availability terms after the two-week preview. Watch also whether real coding-agent evaluations preserve quality while reducing total workflow cost, rather than merely reducing tokens in a narrow test.
