PACE does not ask language models to determine whether transactions are safe. Instead, it uses deterministic rules to check transaction intent, simulation results, and actual calldata. A smart account revalidates the signed policy decision record before execution, though the zero-failure result so far comes only from a simplified DeFi sandbox.

Google DeepMind researchers had the same Gemini policy play both solver and critic, with a weaker frozen model serving as judge. Debate preserved the judge’s discriminative ability and recovered about 45% of the gap to RLVR, at the cost of more training steps and constrained critique length.

NVIDIA has open-sourced TensorRT Model Connect, which uses two commands to turn supported Hugging Face or local checkpoints into versioned bundles that can be handed off to C++ applications. It shortens the model-porting path, but remains a reference implementation; support and performance must be validated for each model, precision, and hardware configuration.

PTXBench checks whether generated kernels are correct, whether specified instructions actually execute, and how their performance compares with cuBLAS, cuDNN, and FlashInfer. The results show that generating instructions for new architectures does not necessarily translate into effective acceleration, with B200 attention kernels proving especially difficult.

The new system binds a document agent’s search results, native files, diff views, and final submissions to explicit versions, preventing the agent from reading stale parsed content while editing a newer file. Ablations within a fixed framework show that providing both parsed and native views outperforms either view alone, though the full codebase and cross-framework reproductions are still needed.

A new study moves evaluation upstream to the initial-contact stage, before patients have clearly described their problems. Adding a “clarify first, advise later” system instruction improved response sequencing and handoff summaries, but still did not reliably elicit decisive medical history.

Qualcomm AI Research adds per-layer fast weights to a frozen Transformer, absorbing context in 512-token segments so queries no longer need to read the source text. In 128K experiments, Qwen2.5-0.5B maintained fixed memory usage and outperformed ICL and RAG, though the evidence is currently limited to three synthetic retrieval tasks.

TokEval incorporates numeric place value, program AST boundaries, UTF-8 integrity, and cross-lingual cost into tokenizer evaluation. Controlled experiments show that some metrics can predict specific downstream capabilities, although the results are currently limited to a single 1.27B-parameter architecture.

Microsoft rewrote Agent Lightning to capture complete interactions from existing agent frameworks through a model API proxy layer, eliminating the need to move tool loops into the training engine. Using 6,000 training examples, the team reports that Qwen3.5-9B improved from 41.8% to 56.4% on SWE-bench Verified.

The open-source rl-triton library rewrites credit-assignment recurrences such as GAE, V-Trace, and Retrace as Triton associative scans, reducing sequential dependency depth from O(T) to O(log T). In tests with 4,096 environments and 128 steps, it was 1.6× to 5.70× faster than an already vectorized torch.compile baseline, although end-to-end PPO speedup for large policies was only about 1.02×.

Rather than removing token connections, TileMix selects either the FP16 or INT8 Tensor Core path for each attention-score tile within a single fused kernel. It reaches 31.80K token/s on a 4K LLaMA 3.2 3B benchmark, though the results are currently limited to A100, static routing, and the prefill stage.

Salesforce reevaluated two text-based memory methods and found that adding a self-improvement loop increased run-to-run variance in 71% of configurations. Once the fixed task order—which implicitly formed an easy-to-hard curriculum—was shuffled, ReasoningBank not only failed to improve the agent but reduced its success rate.
