Open-weight release cluster: DeepSeek V3.2 + Qwen3-Omni + Magistral + Kimi K2 + GLM-5.2 + open-r1 land in one week

The week of 2026-08-03 saw a cluster of open-weight releases across frontier-class capabilities: DeepSeek V3.2 (sparse MoE routing refinements + 128K sliding-window), Alibaba Qwen3-Omni (multimodal vision + audio + text), Mistral Magistral (open-weight reasoning model), Moonshot Kimi K2 (256K long-context + tool-use), Zhipu GLM-5.2 (78-layer compressed-attention MoE), Hugging Face open-r1 (fully open reasoning reproduction). The Decoder frames the cluster as 'every frontier vendor ships an open-weight option'. The pattern: each release slots into a specific capability slot (multimodal / reasoning / long-context / long-form generation) and ships with an explicit license.
