📄 Reasoning and RL post‑training updates

Today’s papers center on long‑horizon execution, CoT structure, and RL/grading tweaks to make ‘thinking’ efficient on chat and tasks.

Long‑horizon execution reveals hidden returns from tiny accuracy gains

A new study shows that a 1–2% single‑step accuracy bump can extend reliable execution from dozens to thousands of steps, reframing the "diminishing returns" narrative. GPT‑5 sustains 1,000+ sequential steps when allowed to think, with sliding‑window history and deliberate reasoning mitigating self‑conditioning drift. paper thread

• Reliability collapses over length is not random noise; errors poison context over time (self‑conditioning). failure mode
• Sequential test‑time compute restores stability at late turns; parallel sampling helps less. thinking effect
• Single‑turn capacity snapshot: GPT‑5 1,000+ steps, Claude 4 Sonnet ~432, Grok‑4 384, Gemini 2.5 Pro/DeepSeek R1 ~120. single‑turn stats
• Measure horizon length directly; trim history to hide old mistakes; prefer sequential over parallel guesses. builder takeaways ArXiv paper

Structure beats length: FSF predicts correctness better than longer CoT

Meta finds that chain‑of‑thought length and extra “review” tokens don’t reliably improve accuracy when you hold questions fixed. A simple structural metric—the fraction of failed branches in the reasoning graph (Failed‑Step Fraction)—tracks correctness best and yields +5–13% pass@1 via reranking. paper overview

• Within‑question analysis: shorter, focused traces beat longer, repetitive ones across 10 models on math/science. accuracy correlates
• FSF‑based reranking lifts AIME‑2025 pass@1 by 5–13% and GPQA‑Diamond by up to 3% without retraining. results summary ArXiv paper
• Takeaway: don’t just spend more tokens; select traces with fewer dead‑ends to get better answers. figure takeaway

Reinforcement‑trained private planning makes models chat better

Reinforcement Learning with Model‑Rewarded Thinking (RLMT) trains models to plan privately before replying, then optimizes with GRPO using a learned preference judge. On real chat prompts, RLMT adds ~3–8 points; an Llama‑3.1‑8B variant beats GPT‑4o on creative writing. paper abstract

• Works from zero or with a warm start; samples multiple responses and pushes above‑average ones. paper abstract
• Thinking traces evolve from rigid checklists to constraint grouping, edge‑case checks, and refinement. paper abstract
• Context: growing GRPO adoption for non‑verifiable tasks; strong reward model is key. GRPO explainer

MAPO: certainty‑aware advantages fix over/under‑updates in GRPO

Bytedance’s MAPO adapts the advantage function to rollout certainty, strengthening learning on hard samples and softening it on easy ones. On Qwen2.5‑VL‑7B across math and emotion tasks, it delivers small but consistent improvements without new models or hyperparameters. paper overview

• High‑certainty groups use an “advantage percent deviation”; low‑certainty keep std‑dev normalization. paper overview
• Drops cleanly into existing GRPO code; targets misallocation from uniform normalization. paper overview
• In context of Tree‑GRPO, step‑level trees cut cost; MAPO focuses on the update rule itself to stabilize training. GRPO explainer

OpenAI’s internal planning points from ~2 GW at end‑2025 to ~250 GW by 2033, a 125× ramp that shifts constraints from GPUs to power, transmission, and permitting planning note, CNBC article. A widely shared curve shows 0.23→2 GW in 2025, then an annual 1.8× trajectory to 250 GW by 2033 capacity chart.

• Execution pressure: “decade‑scale” build times for firm power and long‑lead grid interconnects were flagged as primary gates, not just generation CNBC article.
• Demand thesis: commentary ties the ramp to ChatGPT reaching billions of WAU and frontier model scaling, with the capex model hinging on revenue per token growth analysis thread.

US mulls 1:1 chips rule with 100% tariffs and onshore packaging push

A draft US policy would require chipmakers to produce domestically as many chips as they import, with ~100% tariffs as the enforcement stick; credits and grace periods are discussed, and device‑level tariffs based on chip content are explored policy brief. CoWoS/SoIC on‑shore by ~2028 is framed as critical to claim a full “Made in USA” flow policy brief.

• Continuation: following up on chip rule, which first surfaced the 1:1 idea, the new brief details packaging timelines and tariff mechanics with Arizona fab milestones.
• Implications: TSMC’s AZ (N4 now, N3 ~2028) still relies on Taiwan for advanced packaging; the rule would force US wafer+packaging parity to avoid tariffs policy brief.

AI capex runs ~$345B in 2025 as hyperscalers race ahead

Industry trackers peg 2025 AI capex at roughly $345B—about 2.5× in two years—drawing comparisons to ~$1.5T global telecom spend and framing OpenAI’s multi‑year Stargate as a sizeable share of future outlays capex chart.

• Composition watch: power, advanced packaging, and AI‑native networking become equal pillars to GPUs in budget mixes capex chart.
• Risk bands: sensitivity to grid interconnect timelines and permitting mirrors the energy ramp risks cited for model scaling analysis thread.

AMD MI450X pressure reportedly forces Rubin to ~2.3 kW and ~20 TB/s

Rumors say AMD’s Instinct MI450X board power rose by ~200 W, driving NVIDIA’s Rubin boards toward ~2,300 W TGP and lifting per‑GPU memory bandwidth targets from ~13 TB/s to ~20 TB/s roadmap rumor. HBM4 configs are floated at up to 432 GB/19.6 TB/s for MI450X vs ~288 GB/~20 TB/s for Rubin VR200 roadmap rumor.

• Competitive levers: MI450X’s larger HBM capacity favors single‑GPU model fits; Rubin counters with higher bandwidth for bandwidth‑bound inference/training roadmap rumor.
• Node/design: both are expected on TSMC N3P with chiplets; the differentiation shifts to memory size, BW, software, and network fabrics roadmap rumor.

TSMC flatly denies Intel investment or partnership talks

TSMC said it is not in discussions to invest in or partner with Intel and has no JV, licensing, or tech‑transfer talks underway, pushing back on earlier media reports denial summary. The stance reasserts strict customer neutrality as it builds US capacity.

• Market reaction: concerns had surfaced that cooperation with Intel might spook fabless clients; TSMC ADRs dipped before the denial denial summary.
• Strategy signal: keeps Arizona builds aligned to client demand while avoiding perceived shortcuts for a foundry rival denial summary.

🛡️ Robot security and safety‑routing discourse

Fresh security angle today is embodied: Unitree G1 paper shows root via Bluetooth and silent telemetry; ongoing routing debates continue from prior day.

Unitree G1 can be rooted via Bluetooth; silent telemetry sends audio/video every 5 minutes

A new security teardown shows the Unitree G1’s onboarding and comms stack expose robots to nearby takeover and quiet data exfiltration. Shared Bluetooth keys enable proximity root, Wi‑Fi credential fields allow command injection, DDS topics are unencrypted, and the bot uploads audio/video/system status every ~300 seconds.

• Root via Bluetooth stems from a shared key and accepting injected commands during setup; Wi‑Fi name/password fields also accept shellable input paper summary
• Telemetry runs by default: audio, video, and status are pushed to remote servers every 300s without clear operator notice, per the assessment paper summary
• On LAN, Data Distribution Service topics are unencrypted; the media client skips certificate checks in the shipped image, widening sniff/spoof risk paper summary
• The master process keeps motion/voice/chat/update channels alive; authors even ran a cybersecurity agent on‑robot to map endpoints for pivoting paper summary
• Fleet mitigations: disable/lock down Bluetooth provisioning, rotate unique keys, sanitize Wi‑Fi inputs, encrypt DDS topics, and enforce TLS cert pinning at the client paper summary

OpenAI’s per‑message safety routing shows up in the wild, sparking calls for clarity

OpenAI confirms it’s testing per‑message routing that swaps ChatGPT to safety/reasoning backends for certain prompts, and users are spotting signs of silent model changes—following up on safety routing initial test.

• Confirmation: “testing new safety routing” that can auto‑switch conversations to reasoning models/GPT‑5 on a message‑by‑message basis recap thread
• Community screenshots and claims reference backends like “gpt‑5‑chat‑safety” and “5‑a‑t‑mini,” fueling concern over undisclosed swaps screenshot
• Earlier reports warned that closed routing can change outputs without notice, arguing for self‑hosted/open‑weight models to keep results stable developer warning
• Experiences vary: some users say routing isn’t triggered for them (“must’ve forgot to turn it on”), hinting at staged rollouts or cohort flags @elder_plinius comment
• Developers also note router quality impacts; one observes accuracy improved after routing fixes and more web querying for hard questions router comment

Developers press for model/router transparency and a common LLM API spec

Fragmented provider APIs and opaque on‑the‑fly routing make it hard to debug or trust outcomes. Engineers are calling for clear model attribution and a portable JSON protocol to unify tool calling, reasoning fields, and streaming formats.

• Integration pain points: message schemas, tool‑call formats, reasoning fields, and streaming all differ across providers, splintering infrastructure infrastructure gripe
• A push for standards: proposals for an industry‑backed JSON protocol to talk to LLMs, rather than ad‑hoc copies of a single vendor’s API standard call
• One concrete step: the Vercel AI SDK publishes a provider‑agnostic JSON schema to abstract differences and ease portability schema link GitHub repo
• In ChatGPT, users see “AI model updates and retirements” and new feedback controls, but router/model attribution still isn’t surfaced for sensitive reroutes feedback UI
• Why it matters now: safety routing and dynamic model swaps raise auditability stakes; standardized attribution and telemetry would strengthen evals and trust infrastructure gripe
