flux[dev] inference speed
fal Inference Engine™ is
the fastest way to run
diffusion models
Run diffusion models up to 4x faster. Enable new user experiences leveraging our real time infrastructure.
Features
Where developer experience meets the fastest AI.
Inference for Your Private Diffusion Model
If you are training your own diffusion transformer model, we would like to partner with you to run inference on your model. Fal's inference engine can run your model up to 50% faster and cost effective. Scale to thousands of GPUs when needed and pay only for what you use.
Blazing Fast Inference Engine for Diffusion Models
We have built world's fastest inference engine for diffusion models. We can run the FLUX models up to 400% faster than other alternatives.
Best LoRA Trainer In the Industry for Flux
Fal's head of AI research, Simo Ryu, was the first to implement LoRAs for diffusion models. We now bring you the best LoRA trainer for FLUX. You can personalize or train a new style in less than 5 minutes.
import * as fal from "@fal-ai/serverless-client";
const result = await fal.subscribe("fal-ai/fast-sdxl", {
input: {
prompt: "photo of a cat wearing a kimono"
},
logs: true,
onQueueUpdate: (update) => {
if (update.status === "IN_PROGRESS") {
update.logs.map((log) => log.message).forEach(console.log);
}
},
});World class developer experience
Use one of our client libraries to integrate fal directly into your applications.
