INCEPTION LABS' MERCURY 2 AI BEATS GOOGLE'S DIFFUSIONGEMMA AT ITS OWN GAME

Mercury 2 is a reasoning language model that generates about 1,000 tokens per second. It uses diffusion, the same trick that turns static into a photo in image generators like Stable Diffusion. The model is best for speed-sensitive, high-volume parts of workflows rather than the hardest frontier reasoning. It is only available via API/cloud.

AI PAUSES

Claude Fable 5 and Claude Mythos 5 were shut down by the White House via an imposition of export controls. The Trump Administration said it was due to a jailbreak of Fable - this turned out to just be saying 'fix this code'. Anthropic has been told to fix this 'jailbreak', which is impossible. It's now been over a week since the pause in deployment and the situation has yet to improve.

AUDITING DIFFUSIONGEMMA TRANSPARENCY

A transparency audit found that DiffusionGemma remained similarly monitorable to Gemma despite its diffusion-based architecture. The analysis highlighted a gap between variable transparency and algorithmic transparency, and explored phenomena such as non-chronological reasoning, token smearing, and intermediate-context reasoning.

OPTIMIZING MODELS TO BE FAST AT CODEGEN

Morph LLM optimizes open coding models by training a drafter on coding output, not the internet, for faster speculative decoding, achieving a 3.07x speedup. Autoresearch automates kernel tuning for low-demand GPUs like NVIDIA and AMD, enhancing warp-decode kernels to reach 162 tok/s on affordable hardware. Interconnect over PCIe replaces expensive NVLink using custom kernels, maintaining performance by sharing caches via TCP, cutting time-to-first-token by 84%.

FROM PROMPTING AGENTS TO LOOP ENGINEERING

AI coding workflows are shifting from prompt engineering to loop engineering, where developers build systems that repeatedly prompt, evaluate, and re-prompt agents until a measurable goal is achieved.

A VIRAL DOOMSDAY SCENARIO AIMS TO SHAKE EUROPE OUT OF ITS AI COMPLACENCY

A speculative thought experiment called Europe 2031, penned by Brussels-based thinktankers, paints a picture of a world where Europe's lack of investment into datacenters results in it being far behind the US and China. The lack of investment results in Europe's economy being in shambles as it lacks its own AI. In this world, populism is surging, the Euro is wobbling, and cyber-attacks are shredding EU businesses. The scenario was read by members of the European parliament and brought up in discussions between British and German officials last week.
