- DeepSeek shipped V4 Pro and Qwen passed 3 billion downloads as China's open-weight labs keep gaining ground; Snowflake now routes production traffic to both DeepSeek and GLM models.
- Asana replaced 5 years of planned engineering work with 2 weeks of Codex-driven work, for about $12K.
- LangSmith launched trace-level 'Perceived Error' scoring to catch agent mistakes in production.
- Gartner projects agentic inference costs to rise more than fivefold by 2028.
- Cloudflare's WriteGuard adds fine-grained MCP access controls, and the EU's Article 50 watermarking mandate is now in effect.
China's open-weight labs had a big day: DeepSeek launched V4 Pro, Qwen passed 3 billion downloads, and Snowflake's Cortex AI Gateway added routing to both DeepSeek and GLM models — a sign Chinese open weights are now a default option in enterprise model gateways, not just a cost play.
On the engineering side, Asana's Codex migration (5 years of planned work in 2 weeks, about $12K) and new eval tooling from LangSmith and Databricks show teams tightening how they verify agent output as usage scales, right as Gartner warns agentic inference costs could climb more than fivefold by 2028.
Open-Weight Models & the China AI Race 5 items
China's open-weight labs advanced on multiple fronts today — DeepSeek shipped V4 Pro, independent analysis held up Zhipu's GLM-5.3 benchmark claims, and Qwen passed 3 billion downloads — while Snowflake's Cortex AI Gateway added production routing to both DeepSeek and GLM models.
