Best open-source AI models
Open-weight models have closed much of the gap with closed flagships — at a fraction of the price. These are the strongest open models by intelligence, from DeepSeek, Zhipu (GLM), Alibaba (Qwen), Moonshot (Kimi), MiniMax and OpenAI's GPT-OSS.

Frequently asked questions
Here we mean open-weight models — ones whose trained weights are publicly released so they can be self-hosted or run through many providers. DeepSeek, GLM, Qwen, Kimi, MiniMax and OpenAI's GPT-OSS all qualify.
The top open models now rival closed flagships on many benchmarks, especially coding and math, while costing far less. They can still trail the very best closed models on the hardest reasoning tasks.
Yes — on just4o.chat the open models above run through hosted inference, so you get the cost benefits without managing GPUs.
