Broader connector coverage is key for interop‑first agent setups (fewer custom tools, more native APIs).


📊 Evals, Tracing and Leaderboards

Mostly eval releases and reasoning duration work: long‑horizon execution metrics, unified model leaderboards, LLM analytics, and agent tracing/observability from Weave.

LLMs show scaling gains on long‑horizon execution

A new eval study isolates execution (not reasoning) to measure how models sustain multi‑step tasks over time, finding small per‑step accuracy gains translate into exponentially longer reliable task lengths; larger models and explicit “thinking” help, while self‑conditioning (feeding prior errors) hurts. See the abstract and figures in paper preview and abstract figure, and the full methodology in ArXiv paper. Community reaction frames this as a key axis where frontier models may diverge (e.g., GPT‑5 touted as strongest on long‑horizon) opinion thread.

Open deep‑research dataset trains 3B model to beat 32B on browsing evals

BAAI’s InfoSeek synthesizes >50K web ‘deep research’ trajectories by expanding questions into verifiable trees and enforcing tight parent constraints to prevent shortcuts. A 3B model trained on these step‑checked paths outperforms some 32B baselines on BrowseComp Plus, approaching commercial systems. The dataset encodes evidence‑linked steps and rewards efficient browsing, offering a concrete way to evaluate long‑horizon web reasoning paper summary.

New eval suite measures how VLMs build common ground

Northeastern proposes four metrics—grounding efficiency (fewer words/turns over rounds), content alignment (utterance↔image match), lexical adaptation (term reuse), and human‑likeness—to test VLMs in a 3‑round picture‑matching task. Humans are concise and consistent; models over‑talk, adapt less, and still lag. Among tested systems, GPT‑4o mini trends closest to human patterns, but no model matches humans paper overview. Useful to diagnose dialog grounding quality beyond simple right/wrong outcomes.


🧠 Training, RL and Reasoning Advances

Focus on RL for agents and optimizer realism: single‑agent deep research via simple RL, VLA RL frameworks, tiny‑scale VLA adapters, and a sober look at pretraining optimizers’ true gains.

RL recipe powers single agent to 28.7% on HLE, rivaling multi‑agent deep research

Salesforce’s SFR‑DeepResearch shows a minimal single‑agent + simple RL setup reaching 28.7% on Humanity’s Last Exam (HLE), challenging heavier multi‑agent scaffolds paper cover. Key tricks: length‑normalized advantage to curb tool‑spam and context/turn design tuned to the base model (single‑turn boosts for Qwen/QwQ) dev takeaways. Ablations: RL increases tool calls but can shorten step‑lengths on the gpt‑oss‑20B backbone (cleaner chains), while Qwen variants benefited from single‑turn planning ablations chart. For builders: cap tools to force strategy learning; normalize rewards by trajectory length; match scaffolding to model strengths dev takeaways.

Stanford finds ‘new optimizer’ gains shrink to ~1.1× at 1.2B params

New study reports that widely cited 1.4–2× pretraining speedups vanish under fair comparisons: after per‑optimizer tuning and end‑of‑run evaluation, gains fall to ~1.3× at 130M and ~1.1× at 1.2B parameters; matrix‑preconditioned methods (e.g., Muon/Soap) lead at small scale but fade with size paper abstract. This comes in context of AlphaEvolve tiny compute savings, big training impact; here the quantified takeaway is that optimizer wins are modest at frontier‑relevant scales. The paper also shows rankings can flip late in training, cautioning against mid‑run cherry picks paper abstract.

SimpleVLA‑RL scales VLA training with RL, hits SoTA on LIBERO and beats pi0 on RoboTwin

SimpleVLA‑RL introduces an RL training stack for Vision‑Language‑Action models with VLA‑specific trajectory sampling, scalable parallelization, and optimized loss. Applied to OpenVLA‑OFT, it achieves SoTA on LIBERO and surpasses pi0 on RoboTwin 1.0 (and 2.0 noted), while discovering a new emergent policy pattern (“pushcut”) during training paper page, Hugging Face paper. Discussion and further context in a follow‑up post paper page.

BAAI’s InfoSeek synthesizes 50K verified deep‑research trajectories; 3B model tops some 32B baselines

InfoSeek builds open deep‑research data by expanding questions into constrained research trees (planner + browser), enforcing parent constraints to prevent shortcuts, and rewriting into queries that force full walks. The release includes 50K+ tasks with source‑linked, step‑verified trajectories. A 3B model trained on this data beats some 32B baselines on BrowseComp Plus; a small RL loop further trims wasted clicks paper summary.

‘All‑for‑One’ circuit: LLMs do mental math at the last token, not across the sequence

Mechanistic analysis finds arithmetic is largely executed at the final token via a sparse “All‑for‑One (AF1)” circuit: early tokens mostly stage information, a brief mid‑sequence transfer hands context to the last token, which performs the computation. New probes (CAMA and ABP) isolate this pathway; the shortcut fails on word‑problems/code where linguistic/program structure matters paper page. Implication for reasoning evals: last‑token concentration may mask shallow planning unless tasks force multi‑step structure paper page.


🏗️ Compute, Cloud and Economics

Infra shifts and economics: Nvidia scaling back DGX Cloud, rising rent‑back contracts, massive cloud commitments chatter, and enterprise rollouts. Emphasis on cost and platform strategies.

Nvidia scales back DGX Cloud as rent‑back contracts near $15B

Reports indicate Nvidia is reining in its DGX Cloud push, a sign it’s prioritizing partner channels and bespoke capacity deals over operating a competing cloud DGX Cloud shift. In parallel, its “rent‑back” agreements to lease its own GPUs have grown steadily since late 2022 and are now close to $15B by mid‑2025—underlining demand and flexible, off‑balance‑sheet compute economics Rent-back tally. Expect tighter alignment with CSPs and integrators, and continued creative capacity financing structures to smooth supply cycles.

OpenAI–Oracle $300B/5‑year cloud pact framed as core AI infra spend

Commentary from AI engineers argues the reported $300B/5‑year OpenAI–Oracle commitment is not bubble excess but table‑stakes for AI infrastructure $300B view. The view: inference will dominate opex; locking power, land and network early is rational given runaway demand Infra context. If borne out, this spend sets a reference point for hyperscaler capex planning and long‑term pricing for tokens, storage and bandwidth.

OpenAI and Nvidia to announce multi‑billion UK data center build

A multi‑billion UK data center investment is expected to be announced next week UK DC tease, in context of UK plan prior outlines of an OpenAI+Nvidia footprint. New capacity would extend power and land commitments in the region, diversify supply, and tighten Nvidia’s vertical integration from silicon to deployed inference—watch grid interconnect timelines and local incentives.

US HHS enables ChatGPT for all employees, signaling broader gov’t AI adoption

HHS has made ChatGPT available to all staff, one of the largest US federal rollouts to date, implying cleared workflows under privacy and compliance constraints HHS rollout. Beyond productivity, this points to rising public‑sector compute demand and a need for robust guardrails; some see AI access as closing critical service gaps at scale AI doctor take. Expect procurement, data residency and auditing requirements to shape vendor roadmaps.


⚙️ Serving, KV and Throughput

Inference engineering dominated by memory bottlenecks and new cascades: XQuant/XQuant‑CL rematerialization, EvolKV layer budgets, speculative cascades, prefill/decode disaggregation, and Kimi’s checkpoint-engine.

Speculative Cascades cut cost/latency at fixed quality via token‑level deferral

Google’s approach keeps a small model drafting while a large model verifies in parallel, but swaps strict token equality for a policy that accepts “good enough” tokens based on confidences or acceptable next‑token lists—preserving more small‑model work and removing the sequential bottleneck approach summary. The key insight: accept chunks of small‑model text to raise tokens per large‑model call, unlocking throughput improvements without quality loss key insight. Full write‑up, graphs, and API‑agnostic framing are in Google blog post.

Set Block Decoding speeds up inference 3–5× without hurting quality

Meta proposes Set Block Decoding (SBD): fine‑tune existing LLMs (e.g., Llama‑3.1, Qwen‑3) to predict sets of future tokens in parallel, then commit a block per forward pass—cutting passes by ~3–5× at similar accuracy method overview, training and inference. It blends NTP and masked token completion during training, and during inference stores accepted blocks into the KV cache like normal method overview. Paper details and results are in paper overview and ArXiv paper. This is a drop‑in inference accelerator (no arch changes), squarely aimed at serving throughput.

Kimi’s checkpoint‑engine enables ~20s 1T‑param updates across 1k+ H800s

Kimi’s middleware decouples training/inference while rapidly syncing weights: full‑weight broadcast per GPU, shared buffer buckets, IPC handle reuse, rank0 gather, and double‑buffer pipelining drop sync from ~10 min to ~2 min, then to ~20s on H800s (100 GiB/s) engineering thread. Additional fixes address H2D bottlenecks (parallel H2D then D2D), vLLM update stability (param caching), and fault tolerance via RDMA pull from live ranks for ~40s recovery; a dummy vLLM start lets services boot instantly on update engineering thread.

Checkpoint-engine data flow

Crash recovery via RDMA

EvolKV: per‑layer KV cache search that rivals full cache at 1.5% memory

EvolKV treats KV cache compression as a multi‑objective search, evolving layer‑wise budgets to maximize task quality under strict memory caps. On code completion, it surpasses full‑cache performance while using only ~1.5% of memory; on GSM8K it retains up to 95.7% with much smaller budgets paper first page. Takeaway: fixed heuristics (e.g., pyramid or uniform per‑layer) leave performance on the table—learned allocations can deliver large memory savings at serving time.


🧰 Agent & Coding Tooling

Practical agent building and coding workflows: Anthropic’s tool-writing masterclass and eval loop, Claude Code SDK updates, Cursor/CLI agent use, LangChain guides, Replit Agent 3 demos.
