NVIDIA AVO Completes All 183 Levels in the ARC-AGI-3 Public Set With About 12% Fewer Actions Than VISTA

NVIDIA adapted the AVO agent architecture, originally used for evolutionary search over GPU kernels, to interactive reasoning and achieved a 100.00 RHAE score with Claude Opus 5. The results show that agent memory and verification loops can substantially change the performance of the same model, but they cover only public environments, and the comparison with VISTA is not a controlled ablation.

PolicyGuide Constrains Customer Service Agents with Persistent Workflow Graphs, Raising Four-Run All-Pass Rate from 0.42 to 0.62

PolicyGuide does more than block policy-violating actions before tool calls: it tracks incomplete policy steps during every user turn. It improved reliable success rates across three τ²-bench domains, but adds one LLM verification call per turn, and some procedural-compliance metrics were designed by the authors themselves.

Pandora’s Router Factors Model-Evaluation Costs Into Routing, Cutting EmbedLLM’s Combined Loss to 0.386

Google DeepMind formulates the decision of whether to run costly model evaluations as a “Pandora’s box” search problem, deciding sequentially whether an additional assessment is worthwhile based on its value of information. It achieved the lowest average routing regret plus evaluation cost across all three tests, although its effectiveness depends on calibrated signal distributions and cost settings.

Mojo Opens Compiler and Toolchain Source, Enabling Source Builds with a Single Bazel Command

One week after releasing Mojo 1.0, Modular has made the KGEN compiler, tools, and standard library available under Apache 2.0 with the LLVM exception. The source code can now be inspected and built independently, though the compiler is not yet accepting external contributions, and MAX remains under a separate license.

Waymo Unveils 5nm In-Vehicle ASIC: Over 1,000 TOPS for Front-End Sensor Processing

Waymo has disclosed its Robotaxi heterogeneous computing architecture for the first time. Its custom ASICs process camera, lidar, and radar data in real time before passing it to the core inference engine. Because the stated 1,000 TOPS figure does not specify numerical precision or power consumption, it cannot be directly compared with NVIDIA’s or Tesla’s full-vehicle platforms.

Three-Tier Self-Routing Cuts Output Tokens by 41% for a 1.5B Reasoning Model on MATH-500

A new study turns NoThink, Short, and Long into the model-generated first token, allowing it to allocate a reasoning budget for each problem without a separate router. On MATH-500, the method maintains accuracy close to the base model while cutting tokens by 76% on the easier GSM8K benchmark.

Agent Memory Transfers More Reliably When Broken Into Subtasks; Text Skills Lead Code by 2.9 Points on Average

A study spanning nine models and three long-horizon benchmarks finds that skills induced from complete tasks usually make agents perform worse, while those induced from subtasks deliver average gains. Natural-language process notes are also more robust than executable Python skills, though results remain highly dependent on the model and benchmark.

DeepSeek Pro 再傳灰測：一句「I’m doing」讓社群聞到新模型氣味

8 月 21 日前後，DeepSeek Pro 灰測消息在開發者社群延燒；目前可確認的是官方 8 月 21 日公告只發布 Flash Vision 實驗模型，Pro 仍未公布新版本號。社群觀察到的「I’m doing」思維鏈與 B 站實測，更像一次小範圍路由或後端模型灰度放量。

MemTrapBench: Adding Relevant Memories Causes Five Agent Memory Strategies to Lose at Least 10.66 Points

MemTrapBench does not test whether memories can be retrieved. Instead, it examines whether correct, relevant past experiences can lock a model into the wrong strategy or belief. Across two models, all five memory methods underperformed the no-memory baseline, while a simple prompt-based guardrail recovered only part of the loss.

SAPO Lets a Single Autoregressive Model Serve as Both Actor and Critic, Speeding Up Each Agent RL Training Iteration by 33.2%

SAPO uses two causal boundaries in a generated sequence to read out state and action values simultaneously, eliminating the need for a separate critic or multiple rollouts of the same task. Qwen2.5-7B outperforms PPO and GRPO on the overall metrics for both ALFWorld and WebShop, although no public implementation is yet available for verification.

DECOWAM Separates Robot Dog Base and Arm Representations, Cutting Action MSE by 21.7% While Updating Just 25.95 Million Parameters

DECOWAM adds base, arm, and camera egomotion interfaces to the frozen 6.02-billion-parameter FastWAM, using only the current observation at deployment to predict 48 action steps. Its overall completion rate in physical robot tests is only slightly higher than FastWAM’s, but its robustness success rate under base disturbances rises from 12.7% to 30.4%.

Axon Generates Five LLM Backends from a Strongly Typed DSL, Cutting MLX Median Latency to 48.3% of Transformers

Axon expresses model architectures as functional specifications with symbolic tensor shapes, then compiles them to PyTorch, Triton, JAX, MLX, and native vLLM. Across 467 inference tests, it accelerated most generative models, though some BF16, encoder, and sequence-to-sequence models still showed accuracy or performance regressions.
