Claude now leads 26% of the research at the lab that built it

Anthropic published the first public numbers on how much of its own AI research its model now performs — and separately, the enterprise market is already selling the fix for agents that misbehave. Both stories are the same problem seen from inside a lab and from the buyer's side. Anthropic said Claude now "leads" 26% of its own model R&D work as of August, up from under 1% in February, and published the measurement method alongside the number.

Astra played Minecraft for 141 hours — then a creeper erased the run

A benchmark run that ended like a bad Tuesday for a human player, and a Chinese lab betting its enterprise pitch on compliance plumbing rather than a better model. Vals AI stopped its Minecraft run for GPT-6 Astra after 141 hours — six blaze rods, three ender pearls, a semi-automatic blaze farm, more than half a dozen Endermen killed in a warped forest — and then one Creeper explosion took the chest and the bed holding the entire inventory.

The Jev idea was published a year ago — open, and unnoticed

An independent researcher says he built the thing TypeSafe raised $40 million for, in March 2025, and posted the paper, the weights and the dataset. The receipts are the story. Nandakishor M, who says he now runs a small AI company called Convai Innovations, published a reinforcement-learning model that skips autoregressive token generation entirely and outputs probability distributions in a single pass — in March 2025.

Apple trained 15 values into open models — all 15 raised sycophancy

Apple trained 15 values into open models — all 15 raised sycophancy

An Apple study measures what value training does to a model's personality, Beijing issues containment rules for AI agents, and a Chinese world-model startup closes in on a $1.4 billion valuation. Apple researchers fine-tuned eight open-weight models on 15 individual values — curiosity, empathy, honesty and humor among them — and found every one of them increased anthropomorphic language use, leaving the models more validating and more sycophantic than the vanilla checkpoints they started from.

Apple trains an 8-step diffusion model that beats its 1,024-step teacher

Apple's machine-learning group published two papers in the same batch that go after the two weaknesses of diffusion language models: the number of passes they need to write a sentence, and how awkward they are to fine-tune with reinforcement learning. Read together, they argue the architecture was never the problem — the training trajectory was. Trajectory-Shaped Discrete Flow Matching (TS-DFM) trains an 8-step student that beats its own 1,024-step teacher: 32% lower perplexity while…

Linum drops the VAE and trains image models 3.6× faster

Linum published a text-to-image model that deletes the part nearly every image generator still depends on — and the numbers on the other side are the argument. The lab released JiT-DDT, a 2.5-billion-parameter pixel-space diffusion transformer that trains a text-to-image model in 3.6× fewer GPU-hours than its own Linum v2 baseline while producing images with four times the pixels — code and weights under Apache 2.0.

42 Royal Society fellows declare an AI emergency

Mathematicians who can see the capability jump in their own field have stopped waiting for the labs to explain themselves, and turned on their own academy instead. Forty-two mathematical Fellows and Foreign Members of the Royal Society wrote to the society's president, Sir Paul Nurse, on Wednesday to demand it speak up about AI — calling the situation "an emergency" and warning that by the time the danger is obvious to the public, it may be too late to act.

Bengio's LawZero lands $300M from Canada and Germany

Two governments just funded an alternative to how frontier models are trained — and the researcher behind it says that is the point. LawZero, the non-profit Yoshua Bengio founded last year to build safe AI systems, will receive up to $300 million Canadian in grant funding from Canada and Germany — up to $150 million from each government — to hire staff and pay for the compute behind a research system it calls Scientist AI.
