Fireworks AI

Fireworks AI is an AI inference platform that provides fast, cost-effective API access to a wide range of open-source and custom AI models. Founded by former Meta PyTorch team members, Fireworks optimizes model serving for low latency and high throughput, supporting everything from text generation to function calling and structured outputs.

Fireworks differentiates through its inference optimization stack: the platform uses custom serving infrastructure including speculative decoding, continuous batching, and quantization to achieve significantly lower latency than standard serving approaches. It supports compound AI systems where multiple models work together.

In the agentic economy, Fireworks provides the high-performance inference layer that agents need to operate responsively — turning any open-source model into a fast, reliable API endpoint.
