Observability and evaluation platform for AI agents and LLM apps, with tracing, issue detection and experiments on a free plan.

fal.ai
Pay-per-output API for image, video, audio and 3D generation models, plus serverless GPUs and an AI media agent.
What is fal.ai?
fal.ai is a generative media platform that gives developers API access to hundreds of image, video, audio and 3D models, including Nano Banana, FLUX, Kling, Seedance, MiniMax and ElevenLabs voices. Model APIs bill per output, such as per image, per megapixel, per video second or per request, and you are not charged for server errors, queue time or cold starts. Credits are bought in advance, and your concurrency limit grows as you purchase them. For custom workloads you can deploy your own apps on serverless GPUs billed per second, with H100 listed as low as $2.49/hr. fal Agent, in early access, is a chat interface that plans and runs generations across fal's models and is free to access, with optional monthly credit plans at $50, $200 and $1,000. Enterprise customers can get custom per-endpoint pricing, volume discounts and chat retention controls.
Use cases
- Generate images through an API
- Create AI video from text or images
- Add text-to-speech and sound effects
- Generate 3D models from images
- Deploy custom models on serverless GPUs

- Plan media projects with an AI agent
Who it's for
Why use fal.ai
- You pay for successful outputs, with server errors, queue waiting and cold starts not billed.
- Prices are listed per model and can be queried through an API, so cost estimates can be built into your app.
- One platform covers image, video, audio and 3D models, so you avoid integrating each provider separately.
- Serverless GPUs let you run your own models on the same infrastructure with per-second billing.
- Enterprise accounts can get custom rates, higher limits and shorter data retention.
