fal.ai
Sub-second image generation — FLUX 1.1 Pro Ultra, video, audio, and B200/H200 GPU compute
fal.ai is a serverless inference platform specialising in image, video, and audio generation models. Known for sub-second cold starts and competitive pricing on FLUX 1.1 Pro Ultra, Kling v2.1, and Stable Diffusion. The 2026 platform has expanded to include B200 GPU compute alongside H200, and added real-time video generation with streaming output. A leading choice for production AI creative tools.
Luma AI
Dream Machine — high-quality video generation from text and image prompts
Luma AI develops Dream Machine, a video generation model accessible via API. Dream Machine v1.6 generates high-quality video clips from text or image prompts. The 4K variant produces higher-resolution output. Pricing is per second of generated video rather than per token.
