Open-Weight AI Models
AI models with public weights — for self-hosting, fine-tuning and commercial use.
What is this?
- 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.
Why it matters
- 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 open weights?
931 canonical models in our database currently support open weights. The list is regenerated on every data refresh, so it always reflects the latest releases tracked in our catalogue.
What is the cheapest model with open weights?
Qwen3.8 27B from Alibaba (Qwen) is currently the lowest-priced option, at $0.001 per 1M input tokens and $0.001 per 1M output tokens. The full table above is sorted price-ascending.
Which model with open weights has the largest context window?
Llama 4 Scout 17B Instruct (US) (Meta) leads on context at 10M tokens. This may matter if you also need long-document understanding alongside open weights.
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: GLM-5.3-Flash (92), GLM-5.3 (92), GLM-5.2 (90).
How is open weights 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 syncs once a day, regenerates the canonical model list, and rebuilds these pages so newly released models appear within 24 hours.
