In one line each

Kimi K3: Moonshot's July flagship: 2.8T-parameter MoE, 1M context, native vision, and the best published BrowseComp score (91.2%). The strongest agentic challenger to the US frontier, and the largest model whose weights you can actually download.

GLM-5.2: A workhorse open-weight coder: SWE-bench Pro 62.1% and near the top of the React board on Code Arena. Superseded on raw capability by GLM-5.3-Flash, but still the lighter, cheaper option of the two to self-host.
