# Fireworks AI

> Fireworks AI is a generative AI inference platform founded in 2022 by seven engineers — five of whom built PyTorch at Meta — that gives enterprises fast, cost-efficient, and customizable access to hundreds of open-source models. The company's proprietary FireAttention kernels and speculative-execution engine deliver up to 40× faster inference and 8× cost reduction versus alternatives, while its fine-tuning and model-deployment tooling lets companies own their AI stack end-to-end. With $327M+ raised, a $4B valuation, 10,000+ customers including Samsung, Uber, Shopify, and Cursor, and a $315M annualized run-rate as of early 2026, Fireworks AI has become the go-to inference layer for production generative AI applications.

- **Founded:** 2022

- **Founders:** Lin Qiao (Co-Founder & CEO), Benny Chen (Co-Founder), Chenyu Zhao (Co-Founder), Dmytro Dzhulgakov (Co-Founder), Dmytro Ivchenko (Co-Founder), James Reed (Co-Founder), Pawel Garbacki (Co-Founder)
- **Team size:** ~166 employees (January 2026)
- **Products:** Serverless Inference, On-Demand GPUs, Fine-Tuning, FireAttention, FireOptimizer
- **Notable:** Reached $4B valuation within 3 years of founding — became a unicorn in 2025, Grew from 1,000 to 10,000+ customers (10× growth) between Series B and Series C, $315M annualized revenue run-rate in February 2026, up 416% year-over-year

## Products & services

- **Serverless Inference** — Run hundreds of open-source models (text, image, audio, multimodal) with no GPU setup, no cold starts, and pay-per-token pricing. Delivers up to 300+ tokens/second throughput.
- **On-Demand GPUs** — Auto-scaling GPU compute for workloads that need dedicated capacity.
- **Fine-Tuning** — Supervised and reinforcement fine-tuning for models up to 1T+ parameters using LoRA-based methods that are 2× more cost-efficient than competitors. Deploy and switch between up to 100 fine-tuned models at no additional cost.
- **FireAttention** — Proprietary CUDA kernel series (v1–v4) that dramatically outperforms open-source alternatives. FireAttention V1 was 4× faster than vLLM; V4 on B200 GPUs delivers 3.5× throughput vs. SGLang on H200, using FP4 precision.
- **FireOptimizer** — Adaptive speculative execution engine delivering up to 3× latency improvement in production workloads.
- **OpenAI-Compatible API** — REST API compatible with OpenAI's interface for easy migration and integration, giving access to hundreds of models including DeepSeek R1/V3, Llama 3, Mixtral, Stable Diffusion, and more.
- **Enterprise Platform** — HIPAA, GDPR, SOC 2 compliant deployment with 99.99% API uptime SLA, secure deployment options, and dedicated infrastructure.
