About Fireworks AI

Fireworks AI was founded in 2022 by former members of the PyTorch team at Meta AI Research, bringing deep expertise in model serving optimisation. The company's inference platform is built on FireAttention, a proprietary inference optimisation layer that delivers significantly higher throughput and lower latency than standard vLLM deployments for many popular model architectures. The platform serves a range of open-source LLMs via an OpenAI-compatible API, including the Llama 3 family, Mistral, Mixtral, Code Llama, Phi, and Fireworks' own Firefunction models fine-tuned for function calling. The API supports streaming, structured output (JSON mode), and function calling, making it suitable for production AI application development. Fireworks AI has attracted developer adoption through competitive pricing and performance benchmarks, and has enterprise features including dedicated deployments, custom model hosting, and fine-tuning services. The company raised Series B funding in 2024. For European businesses, Fireworks AI is a US company (California) processing data in US data centres. There is no EU data residency option, and while Fireworks publishes a privacy policy with GDPR references, there are no published independent security certifications. For personal data processing use cases in the EU, appropriate SCCs and a transfer impact assessment would be required. Fireworks is best suited for developer and startup use cases, or for enterprise non-personal-data inference workloads where speed and cost are primary factors.
