The weekend's cleanest AI story was not one launch. It was the bill: tokens, power, chips, memory, code review, and the awkward discovery that agents also need a budget.
Welcome to the weekend Around the Horn Digest, the one page you need if you want to sound dangerously informed when everyone else is still saying “AI agents” like it explains anything by itself. This batch had the usual big-company fireworks, but the real plot was infrastructure: Kog made GPUs feel like specialized inference cards, Glean turned token thrift into a sales pitch, AI companies tried to learn the electric grid, and BAGEN found that frontier agents are still weirdly bad at knowing how much budget they have left. Turns out the future of autonomous work still needs someone asking, “Wait, how much is this going to cost?” Let's get into it.
Around the Horn, Weekend Edition
The biggest meta-story this weekend was that AI agents are moving from “can it do the thing?” to “can it do the thing fast, cheaply, safely, and without melting the grid?” Kog's tech preview showed 3,000 output tokens per second per request on 8x AMD MI300X GPUs and 2,100 on 8x NVIDIA H200s, with no speculative decoding, while its technical posts explained the single persistent-kernel design and Delayed Tensor Parallelism that hide communication overhead behind computation and weight streaming.
At the same time, researchers introduced BAGEN, a budget-aware agent benchmark and training framework showing that task success and budget awareness are only weakly correlated, that frontier agents are broadly over-optimistic, and that early-stopping when an agent predicts failure can save 28 to 64% of tokens with a small success hit. That paired neatly with Glean, whose $300M ARR story now centers on cutting enterprise AI bills by using a context graph to send fewer tokens to models.
The punchline: the next wave of AI competition may be less about which lab has the smartest model and more about who can run useful work loops under real-world constraints. Speed, memory, licensing, power, budget awareness, and workflow design are becoming product features, not backend trivia.

🏆 TOP 5 NEWS
- OpenAI launched Rosalind Biodefense, expanding trusted access to GPT-Rosalind for vetted developers, U.S. government, and allied public-health partners building tools for early detection, epidemiological modeling, DNA screening, pandemic preparedness, and medical countermeasures; Axios framed it as a major biodefense push because frontier biology models can aid both defenders and attackers.

💼 AI Productivity, Labor & Economics
- CNN reported that AI is changing software-engineering jobs so quickly that hiring managers are rethinking what makes a good engineer now that models can write code.
- Wharton researchers warned that AI is eroding critical thinking at work through “cognitive surrender,” where workers accept AI outputs with too little scrutiny, become overconfident, and let reasoning muscles atrophy unless leaders build in verification and counter-argument steps.
- The New York Times spotlighted Schneider Electric using AI in manufacturing to make workers more productive instead of replacing them, including by removing repetitive tasks from production of silver tips for electrical contactors.

- Alex Imas echoed Garry Tan's point that AI amplifies existing skill and judgment, meaning experts get better outputs while confused users produce more confused material faster.
🤖 AI Agents & Infrastructure
- Zihan “Zenus” Wang and collaborators introduced BAGEN, with a paper, GitHub repo, Hugging Face dataset, and shortlink, to test whether agents know their remaining token, money, time, and inventory budgets; the team found budget awareness and task success only weakly correlate, models are broadly over-optimistic, and early stopping can save 28 to 64% of tokens with a small success cost.

🔬 AI Research & Models
- Tilde Research introduced Parallax, a parameterized local linear attention method for language modeling that beats vanilla attention at 0.6B and 1.7B scales on perplexity and downstream accuracy, with a decode kernel that matches or beats FlashAttention; sources include the paper, GitHub repo, shortlink, and a duplicate arXiv reference.
- Ted Zadouri presented FlashAttention-4 at GPU MODE, a Blackwell-focused attention algorithm and kernel that tackles shifted bottlenecks in softmax, memory movement, shared-memory bandwidth, and long-sequence workloads; the batch also included a YouTube URL with tracking parameters and a related X post.
- Romain Lopez and team released icCITE-plex, DOGMA-plex, MoCAVI, and PERCISTRA for massively multiplexed chemical screens at single-cell resolution, profiling RNA, 477 surface proteins, 64 intracellular epitopes, and chromatin accessibility across about 410K primary T cells and 2,800 compound-dose conditions; the thread highlighted mechanisms, off-target effects, and TF-driven chromatin-to-transcription links.
- Rohan Paul summarized Yann LeCun's LeJEPA paper, saying it learns hidden world variables reliably only when those causes follow a balanced Gaussian structure; the batch included a shortlink to the paper.
- Scaling Laws for Agent Harnesses, with social discussion links from omarsar0 and ariG23498, argued that agent performance depends less on raw tokens, tool calls, wall time, or cost and more on “effective feedback compute,” meaning whether the feedback an agent receives is informative, valid, non-redundant, and retained for later decisions; in the paper, raw tokens and tool calls explained limited variation (R² 0.33 and 0.42), while the strongest EFC/task-demand version reached R² 0.99 and fixed-budget feedback improvements raised success from 0.27 to 0.90.
- Reflective Prompt Tuning showed function-calling LLMs acting as prompt engineers: diagnosing failure modes, clustering patterns, generating reports, revising prompts with memory, and improving multi-hop QA and math reasoning; Farima Fatahi shared the thread.
- Learn from your own latents and not from tokens, with related social links from Louis Kirsch and Alessandro Favaro, argued that models can learn more efficiently by predicting their own internal representations of related views or masked regions instead of only predicting visible tokens; the paper proves token-level learning can need samples exponential in the hidden-tree depth L, while latent prediction can recover the same structure with samples constant in L up to logarithmic factors, and suggests explicitly stacking H-JEPA-style hierarchies may be largely redundant. Yichuan Wang paired the research mood with a business take: RL-as-a-Service is probably weak right now because enterprise ROI still favors prompt engineering, RAG, memory, tool use, and agent harnesses over slow, operationally heavy post-training loops.
- OmniRetrieval proposed a unified retrieval layer for mixed knowledge sources, with social context from gabriell_lab, Tomasz Tunguz, Keshigeyan, Jinheon Baek, Guinness Chen, and Aparna Dhinakaran; the paper's core idea is that real-world answers live across text, tables, relational databases, knowledge graphs, and property graphs, so the system routes a natural-language question to the right source and native query engine instead of flattening everything into one retrieval method, beating single-source baselines across 13 datasets and 309 knowledge bases.
- FML-bench studied AI research-agent strategies through search dynamics, with Zhengyao Jiang linking the discussion.
- Sakana AI Labs introduced DiffusionBlocks, an ICLR 2026 method for training neural networks block by block through a diffusion interpretation, reducing memory needs while matching end-to-end performance across ViT, DiT, and transformers.
- LEGO Diffusion from UT Austin and ByteDance uses stackable and skippable blocks for variable-resolution diffusion modeling, combining patch-wise local MLP processing, global Transformer processing, adaptive skipping during sampling, and progressive training.
- HuggingPapers highlighted NVIDIA's quantized Qwen3.6 MoE model, 35B total parameters and 3B active, using NVFP4 quantization to shrink memory by about 3x with near-zero accuracy loss and multimodal support to 262K context; Harvey and Trajectory Labs also post-trained NVIDIA's open-weight Nemotron 3 Super on a Legal Agent Benchmark covering 1,200+ complex legal tasks across 24 practice areas, reportedly matching or approaching closed-source frontier models while preserving auditability and data sovereignty.
- CBS News covered “Dreams of Violets,” an AI-generated film that reportedly cost $2,000 and took two months to make with no lights, cameras, or actors.
