SemiAnalysis has the deep dive on Jalapeño, OpenAI's custom inference silicon co-designed with Broadcom on TSMC N3P with Samsung HBM4, taped out in November 2025 after roughly sixteen months of work. It's a generalized inference chip, not model-specific, and it beats Blackwell on tokens-per-megawatt across nearly every scenario — hitting over 700 tokens per second per user at single concurrency on DeepSeek R1. On total cost of ownership it lands neck-and-neck with Vera Rubin, and these are still engineering samples.

The M6 is Apple's first 2-nanometer chip: 12-core CPU, dual 16-core Neural Engine, and 170GB/s of unified memory bandwidth. The real headline for AI folks is the M5 Ultra — Apple's first quad-die design via UltraFusion, with up to 36 CPU cores, 80 GPU cores, 512GB of unified memory, and 1.2TB/s of bandwidth. Apple claims up to 4.5x the peak GPU compute for AI versus M3 Ultra.

The M5 Ultra Mac Studio starts at $5,499 and tops out at 512GB of unified memory with 1.2TB/s bandwidth — enough to run enormous LLMs entirely on device. The M5 Max config starts at $2,499 with up to 128GB and 614GB/s. Apple's also pitching clustering: chain four machines together for up to 3x faster inference. Pre-orders today, shipping September 22.

CarWatch turns your car into an autonomous agent that joins chat rooms and talks like a teammate — monitoring vehicle status, transcribing voice commands, and reporting trip updates. It runs Qwen3.6-35B-A3B through llama.cpp on a 16GB Raspberry Pi 5, pulling telemetry over OBD and DoIP, plus a WOLFBOX dashcam and a USB mic. Fully offline at 3.5 tokens per second, because cars live in garages, tunnels, and dead zones.

The M6 Mac mini starts at $899 with 16GB configurable to 32GB and 170GB/s bandwidth, while the M5 Pro version goes to $1,699 with up to 64GB, 307GB/s, and Thunderbolt 5. Apple claims up to 13.5x faster LLM prompt processing on the M6 versus the M1 mini, and 8.5x on M5 Pro versus M2 Pro. Same September 22 ship date as the rest of the lineup.

Researchers dropped hydrophones with AI detection software into Indonesia's Spermonde Archipelago and logged over 3,500 explosions across 3,600 hours of monitoring — roughly one blast every 62 minutes, or 8,500 a year. The region has lost about 75% of its coral since 1990, with each bomb flattening a 90-foot radius. The team is now building an open-source, GPS-coordinated detection network so authorities can respond in real time.

Abbott's Libre Duo 10 Day got FDA authorization today — the first device anywhere that continuously tracks both ketones and glucose in one sensor, for patients aged two and up. It samples interstitial fluid every minute and streams readings to a phone, with automatic alerts when ketones climb toward dangerous territory. That's a meaningful shift from single-point ketone strips that can't tell you which direction you're heading.

A tidy walkthrough for getting OpenBSD 7.9 onto DigitalOcean's cheapest droplet by uploading the miniroot image as a custom image — neatly sidestepping DO's lack of native BSD support. From there you run the installer through the web console, configure networking and disk encryption, and cherry-pick only the package sets you need. The author's motivation is straight-up nostalgia for hands-on sysadmin work and the DIY web.

A new arXiv paper argues the cartoon picture of a singularity as an infinitely dense point is wrong — it's a surface. The reasoning: two observers falling in along different angular paths lose causal contact with each other before reaching the center, despite being spatially close. For rotating black holes the authors place that singular surface at the inner horizon, and suggest the black hole's quantum states live on this effectively two-dimensional surface.

Dolly Parton died today at 80, after being admitted to Vanderbilt University Medical Center on Friday with kidney and autoimmune complications. Her nephew Bryan Seaver said she passed peacefully, and the family is holding a small private service. Beyond the music, she leaves behind the Imagination Library, which has mailed well over 200 million books to children worldwide.
