LLM API: One Integration, Every Major Model

Not just a proxy - it actually does things other APIs cannot. Send the same prompt to four models at once and see results stream in parallel. Or let one model critique another's output. Or blend multiple responses into a single synthesis. These are native API operations, not hacks.

The widest model selection - 300+ models including niche and fine-tuned variants. The 5% markup is reasonable for the convenience. Best for prototyping when you want to try many models quickly.

The best option for open-source model inference. Fast hosting of Llama, Mistral, and other open models with fine-tuning support. Not a gateway - you are using Together's infrastructure, not routing to other providers.

Optimized for throughput. If you need to process large batches of LLM requests fast, Fireworks' infrastructure is tuned for high-volume workloads.

The fastest inference available. Groq's custom LPU hardware delivers sub-100ms time-to-first-token on supported models. Limited model selection but unbeatable speed for real-time applications.
