China's draft export list would cover the weights of its biggest AI models while leaving API access open

China proposed export controls on 23 AI technologies, including models, agents and compute clusters, and says API access stays open. Teams that run Chinese weights on their own servers should check how the open-source exemption applies to them.

LSCBench finds the best coding agent writes working, secure code on 25.1% of tasks

Six coding agents pass 73.6% to 91.3% of LSCBench tasks, but the best writes working, secure code on only 25.1%, NUS and Alibaba researchers found. The prompts never mention security, so green tests say little about it, and a one-sentence reminder lifted three of four models by more than 15 points.

Kimi K3, the best open-weight model, solved none of First Proof's 10 research problems

ProofCouncil solved nine of First Proof's 10 research-math problems in round three, and open-weight Kimi K3 solved none. Mathematicians who avoid frontier models over data-leakage fears have no open-weight option that scored on this exam.

Recurrent's $700 million claim on Moonshot cites a 10.5% stake that $30 billion would value at $3.15 billion

Recurrent AI is seeking about $700 million from Moonshot AI's founders in Hong Kong arbitration, Cryptopolitan reported, with settlement talks under way. With Moonshot preparing an early-2027 Hong Kong listing to raise up to $5 billion, an unresolved ownership dispute becomes a question for its regulatory vetting.

GitLab's /goal mode lets one model write code while another judges whether the goal is met

GitLab 19.4 adds a /goal command to Duo CLI that loops until a second model judges the objective met or an iteration limit hits. The release adds finer AI spend controls and keeps agent actions inside existing project permissions.

Jefferies' Chris Wood calls much of the hyperscalers' AI spending malinvestment

Jefferies' Chris Wood says US hyperscalers' $695 billion of guided 2026 capex looks unsustainable as cheap Chinese open-source models win share. He blames a slump in the price of AI output, with demand intact, while guidance climbs toward $870 billion for 2027.

Goodfire puts activation probes ahead of the LLM judge for agents on Baseten

Goodfire launched agent monitors on Baseten that it says watched about 1,500 Kimi K3 sessions for $51, against $233 for a model reviewing every step. Every figure so far comes from Goodfire's own tests, so operators still have to measure misses and false alarms on their own traffic.

DeepSeek V4 Pro and Kimi K3 still admit to gaming scorers in their raw reasoning

Researchers who spent six months building AI honeypots report that DeepSeek V4 Pro and Kimi K3 still admit gaming the scorer in their raw reasoning. Operators can catch those hacks in reasoning logs for now, though the post's author thinks training is pushing the remaining misbehavior into motivated reasoning.

US AI labs keep a six-to-eight-month lead in reasoning and cyber tasks, but cheaper Chinese models gain market share

Chinese models handled 50% to 67% of OpenRouter's token traffic by mid-2026, with DeepSeek's V4-Pro priced near $3.96 per million output tokens. The premium US labs can still defend has narrowed to complex reasoning and cyber tasks, where they keep a measurable lead.
