The honest brief
DeepInfra
Among the lowest per-token prices of the hosted-inference providers, with optional dedicated GPU clusters from roughly $2/GPU-hour.
- 100+ models behind one OpenAI-compatible API
- Dedicated GPU clusters (DeepCluster) available
- SOC 2 / ISO 27001, zero data retention
- No hardware to manage
- Pay-as-you-go only, no free tier
- Skews toward open models
- Not a fine-tuning-first platform
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
