Use state-of-the-art, open-source LLMs and image models at blazing fast speed, or fine-tune and deploy your own at no additional cost with Fireworks AI.

The fastest and most efficient inference engine to build production-ready, compound AI systems. Bridge the gap between prototype and production to unlock real value from generative AI.

Fastest platform to build and deploy generative AI Start with the fastest model APIs, boost performance with cost-efficient customization, and evolve to compound AI systems to build powerful applications. Instantly run popular and specialized models, including Llama3, Mixtral, and Stable Diffusion, optimized for peak latency, throughput, and context length. FireAttention, our custom CUDA kernel, serves models four times faster than vLLM without compromising quality.

Disaggregated serving Semantic caching Speculative decoding

Fine-tune with our LoRA-based service, twice as cost-efficient as other providers. Instantly deploy and switch between up to 100 fine-tuned models to experiment without extra costs. Serve models at blazing-fast speeds of up to 300 tokens per second on our serverless inference platform.

Supervised fine-tuning Self-tune Cross-model batching

Handle tasks with multiple models, modalities, and external APIs and data instead of relying on a single model. Use FireFunction, a SOTA function calling model, to compose compound AI systems for RAG, search, and domain-expert copilots for automation, code, math, medicine, and more.
