Fast, cost-efficient inference and fine-tuning platform for open-source models, optimised for production compound-AI systems.
What They Do
Fireworks AI provides serverless inference for 100+ open-weight models with industry-leading latency, achieved through custom CUDA kernels and speculative decoding. The platform specialises in compound AI systems — structured generation, function calling, and JSON mode.
Mission
Enable developers to build production AI applications with fast, reliable, and cost-effective open-model inference.
