Open-Weight AI Models
AI models with public weights — for self-hosting, fine-tuning and commercial use.
Qu'est-ce que c'est ?
- Open-weight models publish their trained weights for download under a license (often Apache 2.0, MIT or a custom open-research license).
- Note: open weights ≠ open source — the training data and code are usually not released.
Pourquoi c'est important
- You can self-host on your own GPUs, fine-tune on private data, run offline, or deploy to a regulated environment.
- Pricing here reflects the cheapest API host — the same model can also be free to run if you bring your own hardware.

Frequently asked questions
How many AI models support poids ouverts?
414 canonical models in our database currently support poids ouverts. The list is regenerated on every data refresh, so it always reflects the latest model releases from models.dev.
What is the cheapest model with poids ouverts?
Whisper Large v3 from scaleway is currently the lowest-priced option, at $0.003 per 1M input tokens and Unknown per 1M output tokens. The full table above is sorted price-ascending.
Which model with poids ouverts has the largest context window?
Llama 4 Scout 17B Instruct (Meta) leads on context at 3.50M tokens. This may matter if you also need long-document understanding alongside poids ouverts.
Which models are available on the most providers?
Production-readiness usually correlates with how many independent providers host the same weights. The top three by provider count are: Kimi K2.5 (45), MiniMax-M2.5 (40), GLM-5 (38).
How is poids ouverts different from a regular LLM?
Open-weight models publish their trained weights publicly. You can self-host on your own GPUs, fine-tune on private data or run offline. Note: open weights ≠ open source — training data and code are usually not released.
How often is this list updated?
Daily. Our data pipeline pulls models.dev once a day, regenerates the canonical model list, and rebuilds these pages so newly released models appear within 24 hours.
