About Fal.ai
Fal.ai (Features and Labels Inc) is a generative media platform founded in 2021 by Burkay Gur and Gorkem Yurtseven in San Francisco. The company raised USD 400 million across 5 rounds including a USD 140 million Series D in October 2025, reaching a USD 4 billion valuation with backing from Andreessen Horowitz, Sequoia Capital, and Meritech. Fal.ai provides developers with tools for creating audio, video, and images using AI, featuring a high-speed inference engine optimized to run diffusion models up to 4x faster for real-time generative media applications. The platform uses output-based pricing (per image, megapixel, or video second) for most hosted models, with specific pricing like FLUX.dev at USD 0.025 per image, while custom deployments use GPU-based pricing with H100s available from USD 1.89/hour. Fal.ai offers a freemium model with free credits for testing and pay-per-use plans for higher volumes. With 101-250 employees, the company has established itself as a leading platform for AI-powered media generation.
