🔬 New AI Craft
1. VibeThinker — 3B model beats Opus 4.5 with novel SFT+GRPO training pipeline
A new paper demonstrates that a 3B parameter model, trained with a two-stage pipeline (SFT for foundation + GRPO for reasoning chain reinforcement), outperforms Claude Opus 4.5 on multiple reasoning benchmarks. The key insight is that small models with carefully designed training can surpass much larger ones — suggesting agent "brains" don't always need the biggest model.

2. The Coming Loop — Armin Ronacher on the AI coding loop trap
Flask creator Armin Ronacher reflects on the growing pain of the AI-assisted coding loop: generate → review → fix → regenerate, which gets longer and more painful over time. Unlike your Agent Plan workflow, Ronacher argues the problem isn't tool intelligence but the lack of an exit mechanism — proposing "layered trust" as a way to break the deadlock.

3. AI's Affordability Crisis — inference costs are the real bottleneck
An in-depth analysis argues that while training costs are plummeting (thanks to DeepSeek and open models), inference costs grow exponentially at scale. The article estimates monthly inference costs for a mid-sized agent system and argues architecture decisions should prioritize inference efficiency above all else.

🛠️ Tools & Tips
1. Claude Tag — bookmark code context for Claude Code
Anthropic launches Claude Tag, letting you annotate files with special tags that Claude Code can reference precisely in conversations — like bookmarks for your codebase, drastically reducing context noise.

2. Baidu Unlimited OCR — one-shot long-horizon document parsing
Baidu open-sources Unlimited OCR, which parses entire documents (complex layouts, tables, formulas) in a single pass without page splitting. For RAG workflows with PDFs/scans, this beats traditional page-by-page OCR on both accuracy and layout preservation.

⭐ Open Source Highlights
1. Forsy-AI/agent-apprenticeship — 854⭐: AI agents learn from real work
Agents accumulate experience through iterative "work → feedback → learn" loops, building reusable skill libraries. Unlike one-shot prompting, agents evolve continuously.
