   T2TechCrunch：AI（RSS）

   Writer has introduced a new AI model developed as a post-training variation of Z.ai's open-source model GLM-5.2. The company claims the new system delivers deployment-ready capabilities at a significantly lower price, thanks in part to an upgraded 'harness' designed to contain token costs. This move reflects a broader trend of building cost-effective models on top of strong open-source foundations. For enterprises exploring AI integration, the lower cost barrier could make advanced language models more accessible. However, the announcement lacks specific benchmark results and detailed pricing, so potential adopters will need to evaluate the model's performance against alternatives. Writer's strategy focuses on practical deployment rather than raw model innovation, aiming to differentiate through efficiency and cost control. The model appears tailored for production use cases where minimizing operational expenses is critical. As token costs often constitute a major portion of AI service expenses, this approach may appeal strongly to developers and businesses looking for sustainable AI solutions. Further technical details are expected as Writer releases more information.

1. Equivariant Learning of a Transferable Three-Dimensional Classical Density Functional
   T2arXiv AI/CL/LG（论文）

   Collective behavior in liquids depends sensitively on thermodynamic conditions, interfaces, and confinement, yet predicting each new state typically requires a separate atomistic simulation. Classical density functional theory offers a reusable variational description, but its central excess free-energy functional is generally unknown, and learned approximations have largely remained restricted to planar or lower-dimensional settings. This work demonstrates that the functional can be learned directly from fully three-dimensional equilibrium density fields while preserving spatial symmetry and variational consistency, without free-energy or chemical-potential labels. A single learned functional transfers across temperatures, system sizes, and statistical ensembles, and recovers structure factors, the equation of state, liquid-vapor coexistence, and interfacial broadening, none of which are used as training targets. Applied to complex three-dimensional geometries, it predicts the non-monotonic force associated with formation and rupture of a solvent-depleted bridge between colloids and adsorption in an interconnected gyroid pore. These results demonstrate that equilibrium density data can be converted into a transferable thermodynamic generator connecting microscopic liquid structure to response, phase behavior, and collective phenomena.

2. Defensive Boosting: A Unified Algorithm for Online Probabilistic Forecasting
   T2arXiv AI/CL/LG（论文）

   This paper introduces the Defensive Booster, a simple algorithm for online probabilistic forecasting that simultaneously achieves the guarantees of online gradient boosting and online weak-to-strong boosting. On any adaptive sequence, its Brier score competes with the best prediction induced by the span of H; when the smooth weak-learning condition holds, its classification error and Brier score match the rates of online classification boosting. The algorithm accesses only a single weak learner, is highly efficient, and outperforms several baselines on synthetic and real data streams with orders-of-magnitude faster runtime.

3. QuoteBench: How Matched Scores Can Hide Command-Path Failures
   T2arXiv AI/CL/LG（论文）

   QuoteBench shows that matched execution scores cannot tell command-generation errors from failures introduced after generation. Using exact final-state validation on 56 one-shot tasks from 14 incident-derived families, the paper crosses the generation contract with an execution transport built around a deliberately unescaped added parser. Replaying the same reply through the added parser lowers success by 55.4-73.2 percentage points across eight same-window configurations; disclosing the boundary recovers 30.4-60.7 points for six configurations. GPT-5.6-sol's matched gap of -3.6 points hides -64.3 points of damage and +60.7 points of compensation. Deployment configuration can reorder models, so evaluations should report the full pipeline rather than treat a matched score as an intrinsic model property.

4. DARTree: Speculative Diffusion Decoding with Autoregressive Draft Trees
   T2arXiv AI/CL/LG（论文）

   Speculative decoding losslessly accelerates autoregressive language models by verifying multiple draft tokens in parallel. Diffusion-based drafters reduce proposal latency by predicting an entire token block in parallel, but their position-wise distributions are marginal rather than conditioned on tokens selected along each draft path. DARTree is a training-free speculative decoding method that extends a pretrained AR correction head from chains to trees. It constructs a fixed-width candidate tree by expanding and scoring all nodes at each depth in a single batch, then applies best-first pruning to select the verification tree. Across seven math, code, and chat benchmarks, DARTree achieves the highest average acceptance length and speedup in all four model-temperature configurations, accepting up to 12.97 tokens per verification round, 98.6% more than DFlash and 27.9% more than Domino, and reaching up to 9.73x lossless speedup over autoregressive decoding.

5. CAPRI: Contract-Aware Proof Repair for Isabelle
   T2arXiv AI/CL/LG（论文）

   CAPRI presents a contract-aware proof repair workflow for Isabelle, where Isabelle checks the proof and an independent checker enforces a machine-readable edit contract to ensure large language models only modify developer-authorized content. The system retains prompts, proposals, candidate repositories, diagnostics, verdicts, and hashes for audit. The study evaluates five workflows on twelve failed proofs from four developments, with three replicates per task and condition, totaling 180 runs and 138 valid repairs. A proof-body-only interface achieved 29/36 valid repairs with zero contract violations, compared to 31/36 for the corresponding full-theory workflow. One-shot repair produced 22/36, while a later prospectively frozen iterative workflow produced 32/36. The results indicate that restricting edits to the proof body provides a favorable balance of effectiveness and safety.

6. AutoDesign: Meta-Harness Optimization for Long-Horizon Agentic Design
   T2arXiv AI/CL/LG（论文）

   AutoDesign presents a meta-optimization framework that leverages a code agent to recursively improve the model-harness system based on rollout feedback, enabling self-improving long-horizon agentic design. The paper focuses on academic paper-to-poster generation and introduces PosterBench, a benchmark comprising 100 papers across five disciplines. AutoDesign achieves a score of 78.32 on PosterBench Main Track, surpassing the closed-source commercial system Claude Design by 7.45 points. Across seven controlled code-agent-model configurations, integrating the learned DesignHarness consistently improves performance, increasing the average PosterBench Score from 54.99 to 67.39 (+12.4%). In a fully autonomous long-horizon loop, it executes 253 tool calls and 11 editing turns within 40 minutes for under $3, reaching average conference-poster quality in human evaluation. A system-blind human study further demonstrates that AutoDesign achieves the highest human preference among evaluated systems.

7. Beyond Final Scores: A Systematic Evaluation of Agents for Long-Horizon AI Research and Development
   T2arXiv AI/CL/LG（论文）

   This paper presents a new framework using rule-based metrics to characterize within-run behavior through Solution Framing, Execution, and Feedback Control, and performs controlled comparisons of seven frontier models on 36 long-horizon tasks to assess experience reuse. Results show current agents operate more like engineering optimizers than fully autonomous researchers: they can formulate and implement practical solutions, but performance varies substantially across runs, their strongest solutions mainly adapt or combine established techniques, and genuine methodological novelty remains rare. Detailed analysis reveals distinct process bottlenecks behind similar final outcomes, experience reuse that can help or mislead, and harness designs that affect stability, suggesting concrete directions for improving model training, inference-time strategies, experience management, and harness design.

8. DFM Mimir v1: An Open HRM Delivering Frontier Performance at 1B Parameters Using Only Permissible Post-Training Data
