# HiDream-I1 Full, Dev, Fast and E1.1 editing

Teams maintaining or adapting a local HiDream generation and editing workflow.

- **Availability**: available
- **Where it runs**: local
- **Costs**: Local costs are GPU compute and storage; verify availability and fees before choosing a hosted service.
- **Adult content policy**: unverified

HiDream-I1 makes most sense for a team with an existing HiDream workflow or a specific reason to evaluate it. Full generates images from text, Dev and Fast are distilled generation variants, and the related E1.1 model edits an existing image from instructions. Local weights leave room for experimentation, but the pipeline brings several components to install and license. MIT covers the HiDream transformers; the VAE and text encoders have separate terms, including Llama's. For character assets, assess consistency across poses and how much correction each image needs. Publisher benchmark scores leave those production questions open.

## Commercial use & license

HiDream transformers use MIT. The official cards require compliance with the separate VAE and text-encoder licenses, including the Llama 3.1 Community License.

## Adult content rules

The model cards do not establish whether explicit adult content is permitted; local execution does not resolve rights or any hosted provider's terms.

[Read the policy](https://huggingface.co/HiDream-ai/HiDream-I1-Full)

## What you need

The official setup uses CUDA, Flash Attention and the HiDream transformer, VAE and text encoders; CUDA 12.4 is recommended for manual installation. E1.1 also calls for current Diffusers. Automatic Llama downloads require license acceptance and Hugging Face login. Allow storage for all components and measure memory for your chosen workflow.

Ranks are recommendations for the task described, based on reviewed documentation. Model ranks cover non-explicit development work. We have not run practical benchmarks. Check content policies and commercial terms separately. [How the ranks work](https://bestadultgames.io/en/developers/methodology.md)

## Why consider it

- Full, Dev and Fast generation variants, plus E1.1 instruction-based editing.
- MIT-licensed HiDream transformers.
- Downloadable models for local experimentation and adaptation.

## Tradeoffs to plan for

- VAE and text encoders carry separate license terms.
- Multiple model components add to memory and setup needs.
- Publisher benchmarks do not establish character consistency or correction effort.

The tier reflects documented fit for the workflow described here and availability. No numeric score or hands-on performance results are provided.
