Decision in 20 seconds
If you want to track Chinese open-source AI models well, ground the routine in repo movement, model cards, and usable release paths. RadarAI is the first routing layer, but the actual decision comes from whether the repo, weights, docs, and license create a realistic path to testing.
Key points
- DeepSeek, QwenLM, and THUDM maintain active GitHub repositories with frequent model and tooling updates.
- StepFun (not THUDM or QwenLM) released a 600B MoE model in October 2026, per RadarAI evidence.
- GitHub remains the primary source for tracking releases, weights, and documentation for these models.
What changed recently
- StepFun open-sourced a 600B MoE model (Step 5 Preview) on October 17, 2026.
- DeepSeek launched a web search API priced at $5 per 1,000 calls on October 17, 2026.
Explanation
The evidence confirms recent infrastructure and model releases from Chinese-aligned teams — notably StepFun and DeepSeek — but does not indicate new major versions or architectural shifts from QwenLM or THUDM in the same timeframe.
THUDM and QwenLM repositories remain high-activity hubs (per their GitHub URLs), but no specific October 2026 model releases are documented in the evidence for those orgs; builders should verify changelogs directly.

FAQ
Is THUDM’s ChatGLM still actively updated?
Yes — THUDM’s GitHub shows ongoing commits to ChatGLM-related repos, though no major version update is cited in the October 2026 evidence.
Are these models truly open source?
All listed projects publish weights, code, and licenses on GitHub; verify license files (e.g., Apache 2.0, MIT) in each repo — terms vary by model and version.
