MCP context tools, a hackable coding agent, and useful dev utilities. Also: local Stable Diffusion on iPhone.

Unabyss — MCP-native self-updating context layer for AI Extracts your context from LinkedIn, Notion, Gmail, Slack, GitHub in under 90 seconds. Structures it into layered files (persona.md, voice.md, company.md) that any AI tool can pull via MCP. Granular per-tool permissions — share voice.md without exposing professional.md. Works with Claude, Cursor, Claude Code, and any MCP-compatible agent.

Anthropic overtakes OpenAI in business adoption, a new 4B document extraction model, quantum-enhanced AI training, and the Vatican weighs in on AI.

Anthropic Overtakes OpenAI in Business Adoption for First Time

Ramp's AI Index shows Anthropic at 34.4% business adoption vs OpenAI's 32.3% — the first time Anthropic has led. Over the past year, Anthropic quadrupled business adoption while OpenAI grew just 0.3%.

The engine behind the growth: Claude Code, which became the fastest-growing product in Anthropic's history. Overall AI adoption across businesses crossed the 50% mark.

NuExtract3 — Open-Weight 4B VLM for Document Extraction Apache-2.0 licensed 4B model based on Qwen3.5-4B. Converts images/PDFs to structured Markdown and JSON. Handles scans, receipts, forms, invoices, contracts, and tables. Outperforms NuMarkdown 8B on most benchmarks at half the size. Self-hostable for RAG pipelines.
Quantum Computer Used to Train AI Model — Answers Questions Base Model Couldn't Scientists used an IBM quantum computer to fine-tune an AI model, producing correct answers on questions the classical base model got wrong. Early but notable intersection of quantum computing and LLM training.
Chris Olah Responds to the Vatican's AI Encyclical Anthropic's Chris Olah published a detailed response to Pope Leo XIV's encyclical "Magnifica humanitas" on AI. A rare intersection of mechanistic interpretability research and Catholic social teaching on technology ethics.
OpenAI's Trillion-Dollar IPO Filing — The Big Questions Fortune breaks down what OpenAI's anticipated IPO filing may reveal: actual revenue numbers, compute costs, the Microsoft relationship details, and whether the for-profit conversion is truly complete.

Quick hits — local models and inference.

MiniCPM5-1B — Tiny Vision-Language Model New 1B parameter VLM from OpenBMB. Small enough to run on phones and edge devices with competitive multimodal understanding.
MiMo-V2.5-coder — Strong Local Coding Alternative If you have 128GB, this is an excellent alternative to Qwen3.6 and DS4 for coding. Fast with reliable tool calling.
