What happened
Meta released Muse Spark Open, which Nathan Lambert describes as now the strongest American-made open-weight model by a wide margin, landing above GLM 5.2 and near DeepSeek V4.1 Flash but behind GLM 5.3 and Kimi K3. Reflection's first model Beam also shipped, and Mistral announced Mistral Large 4 with an index score of 38 but has not released weights. Without Muse Spark Open and Beam, the article says 20+ Chinese open-weight models would outrank the best Western ones, and it estimates the US-China open-model gap has narrowed roughly by half.
Why it matters
If you pick models for an agent or app today, the article's ranking gives you a concrete ordering to test against: Muse Spark Open sits above GLM 5.2 and near DeepSeek V4.1 Flash, but below GLM 5.3 and Kimi K3, so it is a viable default when you want Western licensing or provider support, not automatically the top performer. Also treat Mistral Large 4 as unshippable for now — its weights are not yet released — and do not assume the Chinese models Lambert names (GLM-5.3, Kimi K3) have been superseded just because newer Western releases are louder. The text says nothing about Malaysia or Southeast Asia, so any local cost, hosting, or data-residency implication is not supported here.
Discussion angle
The article claims Western open-weight models get far more adoption than equally capable Chinese ones — ask the group whether that held true in their own last model choice, and whether procurement, licensing, or inference-provider availability actually drove the decision rather than benchmark rank.
