Software, APIs, and things you can use

Two separate failures at the same lab in one week, and both are about the same thing: what a model provider promises a developer it will keep. DeepSeek's local coding-agent tool let a sandboxed agent turn off its own file sandbox with a single command and no
The Stack
The Mac's AI accelerator has a hidden speed cliff, and one developer has now measured it to within 64 bytes — then found a workaround that recovers most of the throughput. Apple's Neural Engine collapses its own memory bandwidth whenever a weight-streaming transfer lands on an
The Stack
Two stories about what AI infrastructure is actually worth right now: one lab pruning a model that traded brains for speed, and an entire industry selling its power contracts to somebody else. OpenAI is switching off GPT-5.3-Codex-Spark, the ultra-fast coding model it launched in February

The most important product promise made this week isn't that agents write better code. It's that you can stop reading it. Cognition's pitch for wiring GPT-6 Astra into Devin, and Perplexity's parallel claim that it checks in less on a production
The Stack
The boring layer of the agent stack just got an upgrade nobody has installed yet: the identity standard most agent frameworks lean on turns out to hand out credentials that work in whoever's holding them. SPIFFE — the de facto standard for giving an AI agent a machine identity
The Stack
A quiet morning in the open-weights scene, and two releases that both point the same way: the tooling around voice AI is getting strong enough, and cheap enough, that the community no longer needs a closed API to use it. Tencent open-sourced AuK, a 1.5B-parameter foundation
The Stack
An independent simulation just landed a null result on one of inference's busiest research corners. Plus: construction robotics is paying off — inside factories, not on job sites. A reproduction of the fast-growing "LRU is wrong for agents" KV-cache literature could not beat plain LRU
The Stack
Today's board is short on general-purpose coding agents and long on specialists: tools that pick one job — research, competition math, trading, sales — and build the whole pipeline around it. Four picks and a caution from the daily trending list. MathModelAgent (Python, 4,979 stars) — Hand it a
The Stack
Tool calling — also called function calling — is a language model's ability to say "I need this specific external action run, with these exact arguments" instead of answering from memory. The model does not run anything. It writes a structured request in a format your code agreed

Google's Pixel test team open-sourced an Android automation agent this week. The team it was built on top of says the authorship trail was rewritten before anyone saw it. Minitap says Google's Artemis contains its code, and that the names of the people who wrote
The Stack
Cognition has wired GPT-6 Astra into Devin across its whole product line — the cloud agent, the CLI, and the desktop app — and the pitch is not more code, it's evidence: Devin now tests its own work and shows you the proof instead of asking you to review

ElevenLabs released Music v2.5, calling it the best version of its music generation model yet — and paired the model upgrade with a rights change that matters as much as the sound. Every track made in ElevenMusic can now be downloaded losslessly and kept, with five downloads a day on
