DeepSeek vs Qwen
Two of the strongest open-weights families, with different centers of gravity.
DeepSeek and Qwen are frequently named in the same breath: both are open-weights families that have competed at the top of public leaderboards. Berges AI runs both, so the question is which one for which task.
DeepSeek, from the lab of the same name, is best known for reasoning, math, and code, and for training efficiently. Qwen, from Alibaba, is known for an unusually wide range of model sizes, strong multilingual performance, and a Max line at the very top of the open-weights field.
On Berges AI, DeepSeek is the quick, light model and Qwen 3.8 Max is one of the large ones. Switch between them from the sidebar. Both reason before every answer.

How they're different
Quick model vs large model
On Berges AI, DeepSeek is the fast, cheap model. Qwen 3.8 Max is far larger: it goes deeper on hard questions and long, multi-step work, and costs more units per reply.
Languages
Both are capable multilingual models. Qwen is particularly noted for breadth across many languages, including Asian languages. DeepSeek is strong too, with its reputation built more on technical reasoning.
Licensing
Both are permissive for almost everyone. DeepSeek uses an MIT-style license. Most Qwen sizes ship under Apache 2.0; the Max model uses Alibaba's own Qwen license, which adds conditions only for very large businesses.
Which one, and where
Stay on DeepSeek for everyday questions and quick reasoning. Switch to Qwen when the problem is hard, long, or code-heavy and a quick answer feels shallow. On Berges AI you get both.
Both DeepSeek and Qwen run on Berges AI today. Switch between them from the sidebar at any point.
