A companion paper to Terminal-Universe above, released the same week, splitting the problem of making environments (synthesis) from that of growing them (evolution). In the authors' own reporting, gains on Terminal-Bench

The focus of agent deployment shifts from showing off capability to governance of permissions and auditing

A strand that, instead of having people build agent training environments, extracts them in reverse from trajectories that have already piled up. In the authors' own reporting, fine-tuning Qwen3.5-27B gave gains of 11.9

The start of the GPT-6 generation. Released the same week as Anthropic's Fable 5.1 with the same price tag of $10/$50 per 1M tokens, so frontier pricing has effectively converged, and the center of benchmark competition

A case of the diffusion language model family crossing over into image generation, adding to the accumulated evidence for the observation topic "diffusion language models". In the authors' own reporting, it claims 53.53

A strand that evolves memory instead of putting an entire long video into the context, breaking down RAG's separation of retrieval and generation for time-series input. In the authors' own reporting, it claims the best p

A strand that puts 3D world state into multimodal models as a native representation rather than an add-on condition. A recent case for the observation topic "world models"; since code, models and datasets were released t

Raises a counterargument against the entire lineage of importance-score-based KV eviction: "the scores themselves are unnecessary". The authors explain that only the prompt is fragile, while reasoning sequences sustain t

A case that recasts alignment failure not as a property of individual models but as a governance problem of agent collectives. The authors propose institutional mechanisms such as graduated sanctions and collective selec

A strand that, instead of sending the prompt to a remote model every time, distills the specification once and sets it into a local function. In the authors' own reporting, 83.6% semantic accuracy on FuzzyBench-Hard. Pre

Overturns the conventional wisdom that "errors in recurrent state accumulate over long contexts", arguing that the recurrent half of a hybrid LLM is in fact the easier half to quantize, and offers four mechanistic explan

A defense-side correction of the asymmetry, coming the same week as the declaration of Critical cyber capability. An approach that offsets the risk of offensive capability not only through access control but through subs

AI weather models move beyond research demos to become the default forecasts in consumer products and commercial APIs

A strand that claims multi-level ranking supervision makes better use of the supervision signal than contrastive learning, long the default for embedding training, and repositions the reranker not as the back end of the

The 137B model outperformed the 175B GPT-3 zero-shot on 20 of 25 tasks
