ANTHROPIC DROPPED THEIR OWN OBSIDIAN BRAIN THAT MANAGES ALL COMPANY INNOVATIONS AND KNOWLEDGE FLOWS
00:22 8,893 nodes, 4,729 links, 8,893 views - a knowledge graph so dense it looks like a galaxy when you zoom out
Marginalia Collection, Glossary Backbone, Comparative Grammar MOC, Oral History Transcripts, Chinese-English Translation Magazine founded 1973 - every cluster its own universe of connected knowledge
Master Index in the center with 9,000+ documents and dozens of cross-references pulling everything together into one navigable system
Field Notes Archive, Translation Studies Index with 419 cross-references, Survey Data pool with 212 coded entries - this is not a second brain, this is an entire research civilization
Fable 5 came back globally on July 1 2026 - and before you run the same prompts you used on Opus 4.8, Anthropic published an official prompting guide because old prompts don't hit the same
the company building the most powerful AI in the world uses an Obsidian graph to manage its own knowledge - and now showed you exactly how to build yours 🧠
Anthropic just dropped 5 workshops, revealing the latest capabilities of Fable 5:
• 00:00 - deep look into Fable 5
• 11:22 - Fable 5 and the capability curve
• 30:54 - building managed agents with Fable 5
• 44:29 - real use cases of Fable 5 by teams
• 57:43 - how to deploy agents with Fable 5
These 1-hour of sessions will replace 100 articles on how to actually use Fable 5.
Watch them today, then read the best practices from the sessions in the article below.
I don't prompt Claude Code anymore.
I have loops running that prompt Fable, and my job is just to write loops.
This is the Boris Cherny method, and I have to say, it's extremely powerful.
Everything you need to get started with loop engineering (as a complete beginner):
The re-release of Fable 5 is probably the greatest thing to ever happen in AI.
I spent the last few hours putting together an ultimate guide to help you master Fable.
Key model differences, loop engineering 101, Fable + Skills, how to build a context memory system & more:
Anthropic engineer:
"Fable is one of those models you’ll just remember - like Sonnet 3.5, Opus 4, Opus 4.5.
We just removed 80% of Claude Code’s system prompt. A new class of models wants a smaller prompt."
in 20-minute session, an Anthropic core engineer reveals the capabilities of Fable.
