Best open-weight models in 2026

The strongest open-weight models in the index, ranked by average benchmark score. 371 models fall into this group.

What the data shows

DeepSeek-V3.2 leads the open-weight group at 84.0. The group median is 67.4.

The price range runs from $0.040 to $5.91 per million input tokens, so 'best' and 'cheapest' are different shortlists.

How to read the ranking

Open-weight models can be self-hosted, which changes the cost model and the data-residency story. The listed API price is only one deployment option.

  • Check the licence before planning a deployment.
  • Compare hosted and self-hosted cost if open weights are available.
  • Test on your own data.
  • Keep a fallback from the other licensing group.
