Model Card

HiDream I1 Full is the flagship text-to-image model from HiDream AI, a 17-billion-parameter sparse Diffusion Transformer that delivers the highest output quality in the I1 family through 50+ diffusion steps.

On verified benchmarks, it scores 0.83 on GenEval (vs. 0.67 for DALL-E 3 and 0.66 for FLUX.1-dev), 85.89 on DPG-Bench for prompt adherence, and 33.82 on HPS v2.1 (vs. 32.47 for FLUX.1-dev and 31.44 for DALL-E 3). It supports negative prompts with a guidance scale of 5.0 for finer output control.

I1 Full is the best choice when image quality, prompt fidelity, and detail richness are the top priorities — ideal for asset generation, creative production, and high-stakes visual content pipelines.

Code Example

Use I1-Full in your app with the Puter.js AI API — no API keys or setup required.

// npm install @heyputer/puter.js
import { puter } from '@heyputer/puter.js';

puter.ai.txt2img("A serene mountain landscape at sunset", {
    model: "hidream-ai/hidream-i1-full"
}).then(image => {
    document.body.appendChild(image);
});

I1-Dev

HiDream I1 Dev is a guidance-distilled, 17-billion-parameter text-to-image model from HiDream AI, built on a sparse Diffusion Transformer architecture with dynamic Mixture-of-Experts layers. It runs in approximately 28 diffusion steps, placing it between the Full and Fast variants in the speed-quality tradeoff. Because it is distillation-trained, negative prompts are not required — the classifier-free guidance scale should be set to 1.0 during sampling. I1 Dev is well-suited for iterative development workflows, concept exploration, and production pipelines where response time matters but image fidelity cannot be fully sacrificed. It also supports LoRAs for style control.

I1-Fast

HiDream I1 Fast is the lowest-latency variant of HiDream AI's 17-billion-parameter text-to-image model family, completing generation in as few as 14-16 diffusion steps. Like the Dev variant, it is distillation-trained and does not require negative prompts. It is the best-fit variant for latency-sensitive API integrations, delivering strong image quality for its step count. I1 Fast is the right choice for real-time generation features, high-throughput batch pipelines, or user-facing products where responsiveness is the primary constraint. Maximum fidelity is reserved for the Full variant.
