LLMs from Scratch: Build a GPT in Pure PyTorch, No LLM Libraries
A bonus chapter on Gemma 3 270M showed KV-cached CPU inference on a Mac Mini M4 (130–224 tok/sec) outrunning an A100 GPU (26–99 tok/sec), which sparked 57 HN comments questioning GPU efficiency at small model sizes. Thi...

ARIS Forces a Rival AI to Audit Every Claim Your Agent Makes
ARIS introduces a named failure mode for autonomous AI agents: 'plausible unsupported success' — where the agent produces internally coherent but evidentially hollow claims its own review loop can't catch. It's a Markdo...

Robot VLA beats GPT-5 on 13 embodied-reasoning benchmarks
Despite claiming complete openness, MolmoAct2's GitHub repo states training code is 'coming soon' — weights and datasets are live, but you cannot reproduce training yet. MolmoAct2 is Ai2's open Vision-Language-Action mo...

CocoIndex: Re-index Only Changed Rows, Skip 99.9% of Re-runs
CocoIndex's flagship claim — 99.9% cache hits when 10 of 10,000 rows change — is mathematically correct but applies only when your corpus changes rarely; a 50% daily change rate cuts that savings to roughly 2×, and no i...

Valkey: Redis fork that hit 1.2M RPS
Valkey 8.0 added async I/O threading that pushed single-node throughput from 360K to 1.19M RPS on an AWS c7g.16xlarge — a 3× gain with no protocol changes. It is a Linux Foundation fork of Redis 7.2.4, launched March 20...

Chipmunk2D: A fast and lightweight 2D game physics library.
In August 2025, Scott Lembcke moved Chipmunk2D's canonical development from GitHub to Codeberg after AI crawlers overwhelmed his website — GitHub now hosts only a mirror, not the upstream. Chipmunk2D is a C library that...
