Microsoft's Mage-VL-Cowork Learns When to Click and When to Code
The open-weight desktop agent combines screenshots and terminal actions in one policy. Microsoft reports 66% on OSWorld-Verified, with important limits on the comparison.
Kimi K3.1 Pro cuts API rates; weights promised by November 4
Moonshot's new model lowers K3's per-token API rates by a third. Independent testing puts it near the top on intelligence, but slow output and heavy token use complicate the savings.
Meta’s Muse Spark Open puts an 816B agent model in public weights, with strings attached
Meta released downloadable weights for Muse Spark Open, a 42B-active mixture-of-experts model with a 1M-token context.

Mistral Large 4: Le Chonk previews enterprise agents before the weights arrive
Mistral's new flagship has credible coding, cyber and document results. Its public preview offers discounted tokens, but independent tests show why agent buyers should watch the whole task bill.
Holo4 uses one model across screens, code and APIs, but its two weights have different trade-offs
H Company's Holo4 models bring GUI, code and tool use into one agent stack. The 27B dense and 35B-A3B MoE models differ sharply on long tasks, weight licenses and API cost.
GLM-5.3-Flash lists at $0.15 / $0.50 — a tenth of Z.ai's own flagship

GLM-5.2: The First Open-Weights Model to Close the Gap on Long-Horizon Coding
Z.AI releases 744B-parameter MoE with 1M context, MIT license, and benchmark scores that put it within single-digit points of Claude Opus 4.8 on long-horizon coding tasks.
