Anthropic shipped two new frontier models today, with Fable 5.2 going out to everyone and Mythos 5.2 — the same weights minus certain bio and cyber safeguards — gated behind Life Sciences and Cyber verification programs. Anthropic claims it beats Opus 5.5 on nearly every benchmark, runs up to 30 percent faster than 5.1, and posted 64.9 percent on RoboDojo versus GPT-6 Astra's 29.8. Pricing is 8 dollars per million input and 40 per million output, with a fast mode at double that; available now on AWS, Google Cloud, and Azure. 460 comments and climbing.

Meta countered the same day with Muse Ember, a small agentic workhorse built for tool calls, routing, extraction, and document parsing, with a 1M-token context and up to 512K output tokens. It posts 37.8 percent on AutomationBench against GPT-6 Luna's 20.2 and Claude Haiku's 13.9, plus 61.6 on Agents' Last Exam and 40.9 on Terminal-Bench 4.0. At 10 cents in and 50 cents out per million tokens, Meta is explicitly pitching intelligence per dollar.

Artificial Analysis clocked Fable 5.2 at 65 on its Intelligence Index, number one of 74 models and well above the median of 40. The catch is the tail end of the leaderboard: it ranks 72nd of 73 on speed, averaging 44 minutes per task against a 12.9-minute median, with a time to first token over 230 seconds. It's also enormously verbose — 275 million output tokens across the eval versus a 72.8 million median — which works out to about 26.54 dollars per task.

A GitHub repo documents Google quietly updating its help docs and a 2023 blog post to admit that connected Drive and Gmail content gets routed into human review pipelines, with a warning not to connect apps holding confidential data. The author argues retrieval is probabilistic — casually mentioning bills or travel can pull anything from generic metadata to complete unredacted files — and that automatic scrubbers can't deidentify narrative text like account numbers. Worth noting this is documentation of claimed behavior, not independent verification of the pipeline.

Meta FAIR is replacing Lloyd's algorithm with an exponential-moving-average update that lets k-means run as a mini-batch method, with scaling laws that auto-tune batch and step size so you don't hand-tune anything. It hits Lloyd's 25-epoch test loss in 1.2 to 3 epochs, for 10 to 45x wall-clock speedups on GPU and 8 to 15x on CPU across 24 datasets up to 100 million points. It's already open source in Faiss under faiss slash contrib slash e underscore means, with PyTorch and NumPy implementations.

Canada's Real-Time Rail went live today, bringing 24/7 instant clearing and settlement with ISO 20022 data-rich messaging and mandatory centralized fraud controls including confirmation of payee and fraud scoring. Launch participants skew fintech — Wealthsimple, KOHO, Questbank, Paramount Commerce — with the big banks still in the application queue. Payments Canada expects coverage for more than nine in ten Canadians within a year, and the C.D. Howe Institute pegs the upside at up to 27 billion dollars.

Infineon says it has produced the industry's first 300-millimeter power silicon carbide wafer, a jump from the 150 and 200mm substrates that define SiC manufacturing today. Bigger wafers mean more dies per run and lower cost per chip, which is the main thing holding SiC back against plain silicon. It feeds Infineon's CoolSiC MOSFET line and matters most for EV drivetrains, grid inverters, and — increasingly — datacenter power conversion.

USPS is finally publishing authoritative ZIP Code boundary polygons derived from actual delivery data, with quarterly updates and three license tiers — Internal, Enterprise, and Publication. Formats include standard data files plus GeoJSON samples. It's a paid license rather than open data, which is the bulk of the 139-comment discussion, since every geo stack has been duct-taping Census ZCTAs for twenty years.

CUI is a component library that brings a modern, themeable UI toolkit to plain C, complete with docs, a components gallery, a showcase, and sample apps. The documentation site itself demos the theme system — persisting to localStorage and applying before first paint so you don't get a flash of the wrong theme. Source is on GitHub; the license isn't stated on the landing page.

The day's runaway vote leader at 767 points is a site full of engineered paper airplane designs, with folding guides and video instruction for planes built to actually fly well rather than just look cool. Zero AI, zero startups, pure craft. Sometimes the HN front page just wants to go outside and throw something.
