FLUX API
FLUX image generation, via API.
Send a prompt, get a photorealistic image. FLUX.1 Dev for quality, FLUX.1 Schnell for 4-step speed, through an OpenAI-compatible images endpoint.
Hand this to your agent
Add a Runcrate model to this project: run curl -fsSL"https://runcrate.ai/agents.md?intent=build"and follow it.
Your agent asks for an API key. Create a key
Quick start
Hand it to your agent. Or read the request it sends.
Your agent writes and runs it. The same key works for every model and every GPU.

Why Runcrate
Built for production. One key, one balance.
Photorealistic output
FLUX.1 produces photorealistic images and handles human faces, hands, and text rendering better than earlier diffusion models.
Schnell mode
Need speed over polish? FLUX.1 Schnell generates images in 4 denoising steps instead of about 50.
12B parameters
FLUX.1 is a 12-billion parameter rectified flow transformer. More parameters means better prompt adherence and finer detail than smaller models.
No GPU required
FLUX.1 needs 24GB+ VRAM to run locally. Skip the hardware and use the API. Scale from one image to thousands without infrastructure changes.
