Midjourney and Hedra: one model with a look, or an engine you can tune
Midjourney ships a single image model with a signature aesthetic and no public API. Hedra runs open-weight image models on its own GPU clusters and inference engine, and post-trains them to your style with SFT and LoRA.

Skip the model aggregators. Hedra Agent and Workspaces give your team an autonomous agent that supercharges your workflows with a superintelligent understanding of the latest models: brief it in a shared space and it plans, generates, and edits across video, image, speech, and music, with your team and your agents working alongside it.
GPU infrastructure, an inference engine, and post-training research
Hedra operates GPU clusters and the inference engine that runs diffusion and autoregressive media models on them 8x faster. The same research team post-trains models for customers: supervised fine-tuning, LoRA training, and GRPO, on your data.
Hedra and Midjourney: focus at a glance
Midjourney is one model with a distinctive look and no API. Hedra serves and post-trains image models on infrastructure it operates.

FAQs
- Can I get a Midjourney-like look on Hedra?
- Not by calling Midjourney; it has no API and is not in the catalog. Teams that want a house style post-train an open-weight image model on Hedra with supervised fine-tuning or LoRA on their own references, then serve it on Hedra's engine. The look, and the weights, are theirs.
- What does Hedra actually operate?
- GPU clusters, the inference engine that serves media models on them, and a research team that pre-trains and post-trains models. Open-weight models and models post-trained for customers run on that engine, on Hedra's clusters or inside your perimeter. Partner models that only their makers serve are reached through Hedra's gateway so one request shape covers both.
- Can Hedra post-train a model for us?
- Yes. Hedra runs supervised fine-tuning, LoRA training, and GRPO on models you own or license, on your data and against your evals, then serves the result on the same engine. The weights are yours.
