Good morning.

Your AI agents just got a stricter teacher, and drones are now spying at 5 GHz.

AI eval

GPT-6.1 matches investors 88.6% of time

Bottom line: OpenAI’s Terminal X evaluation agent aligns with senior investor judgments 88.6% of the time, spotting a quarter more mandate deviations than before.

Why it mattersHelps you trust LLM‑driven trading signals.

Multimodal

Hybrid diffusion‑autoregressive reasoning speeds vision‑language

What’s new: CoRAL spawns K parallel reasoning paths with a diffusion planner, then an autoregressive executor picks the best, cutting compute while staying competitive on benchmarks.

Why it mattersYou can run richer V‑L models on limited hardware.

Embedded

OpenBSD 8.0 adds arm64 hibernate, 512 GB space

System upgrade: OpenBSD 8.0 ships arm64 hibernate support, expands the amd64 kernel address space to 512 GB, and refreshes the Qualcomm Wi‑Fi 6 driver.

Agentic on-policy distillation suffers from teacher myopia: next-token scores let safe, delaying moves pass, causing students to run out of turns despite teacher takeovers succeeding.

Previous remedies focused on keeping training within regions where the teacher is reliable, using curricula or interventions. This work shows that even when the teacher can complete tasks after student divergence, its token-level scoring fails to penalize delayed actions, highlighting a limitation of outcome-agnostic scoring.

CoRAL combines a diffusion planner that generates K parallel reasoning paths with an autoregressive executor that selects the best plan, achieving competitive accuracy and higher efficiency on vision‑language benchmarks.

  • K parallel trajectories

The planner uses Reward‑Guided Denoising to incorporate outcome‑based rewards into diffusion, steering generations toward goal‑directed reasoning. The executor, a large ARM, synthesizes the final answer from the chosen plan, closing the gap between parallelism and semantic coherence.

The SAFE decision layer converts predicted runtimes into conservative walltime recommendations, evaluated on Fugaku (≈24 M jobs) and NREL Eagle (≈11 M jobs) production histories.

  • 24M jobs

The paper analyzes why serving long‑context LLMs on a single GPU locally is limited beyond model size, questioning the need for compression.

It examines memory, bandwidth, and algorithmic constraints across several models, rather than profiling a single model. Findings highlight trade‑offs between context length and latency, informing design of more efficient local inference pipelines.
