Built on Kimi K2, the model is jointly pre-trained on roughly 15 trillion mixed text and visual tokens. Vision is… 2. **[Kimi K3: Open Frontier Intelligence](https://md.research.elamur.ai/free/en/papers/kimi-team-2026-kimi-k3-open-frontier/)** *(2026 · 40 citations)* Open-weight LLMs have advanced quickly in reinforcement learning and test-time reasoning. However, most still sit near the 1T-parameter scale, so their pre-trained base models fall behind proprietary systems. Kimi K3 scales both pre-training and RL. It is a natively multimodal Mixture-of-Experts model with 2.8T total… ## Co-authors here 12 co-authors with a page, the most papers together first. - [H.S.
