Priority tier and Fast mode are in Preview. The features, pricing, and availability may change - we welcome your feedback!
Fireworks offers a Priority tier for workloads that require higher reliability, as well as a Fast mode for workloads that require higher speeds.

​
Priority tier

Priority tier is for workloads that require higher reliability during peak traffic periods, at a higher price point. Priority tier is prioritized above Standard traffic and is less likely to be load shed (503 server overloaded). To use priority tier, set service_tier to "priority". Supported on OpenAI-compatible chat completions and on the Anthropic-compatible messages API: 
curl https://api.fireworks.ai/inference/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $FIREWORKS_API_KEY" \
  -d '{
    "model": "accounts/fireworks/models/kimi-k2p5",
    "service_tier": "priority",
    "messages": [{"role": "user", "content": "Hello"}]
  }'
Priority tier is available on select models. Models and pricing are listed on the Serverless pricing page.

​
Fast mode

Fast mode is a high-speed configuration, useful for interactive applications that require fast response speeds, at a higher price point. Fast variants aim for 100+ tokens per second of generated throughput. It is not a different model and the quality of the model remains the same. Fast mode is available for select models. To use Fast mode, change the model id as listed below.
