Fireworks AI — Technical Overview
Fireworks AI is a high-performance inference and fine-tuning platform built for AI developers and enterprises. It provides serverless and on-demand GPU infrastructure optimized at every layer of the stack for high-throughput, low-latency model serving.
Core capabilities:
- Inference: Serverless inference across a broad catalog of open-source models (DeepSeek, Llama, Mistral, Qwen, GLM, Kimi, Gemma, and more), billed per token (input, output, and cached).
- API compatibility: Drop-in replacement for OpenAI and Anthropic API clients — swap the base URL and key, no other code changes required.
- Fine-tuning & training: LoRA SFT training on models up to 16B parameters; reinforcement learning training supported. Training billed from $0.50/1M tokens.
- Deployment options: Serverless (auto-scaled, pay-per-token) or on-demand dedicated GPUs (H100 from $8.00/hr; GB300 from $20.00/hr).
- Advanced serving features: Multi-LoRA serving, post-trained model support, and multi-region deployments for latency and compliance requirements.
- Embeddings: Available from $0.008/1M tokens.
Integrations: Azure, OpenAI API, Anthropic API, Cursor, Vercel, Notion, Sourcegraph, UiPath, Gumloop, Quora.
