The honest brief
Cerebras
Wafer-scale CS-3 hardware tops every rival on tokens/sec — fastest pure throughput for agent loops.
- Highest tokens/sec in the market
- Low time-to-first-token (~80-150ms)
- 2-3x faster end-to-end in agent loops
- OpenAI-compatible API, free daily tier
- Smaller model catalog than Groq/Together
- Less mature ecosystem and client libs
- Occasional capacity limits under demand
Fireworks AI
Runs open models on its own FireAttention serving stack, tuned for lower latency than off-the-shelf inference runtimes.
- Custom FireAttention inference stack
- Vision and audio models, not just text
- Serverless + dedicated options
- Fine-tuning supported
- Usage pricing scales with traffic
- Open-weights focus, not proprietary frontier
- Dedicated capacity costs more
