AI Builder Notes - Week of June 14, 2026

AI Builder Notes - Week of June 14, 2026 My thoughts and my twitter’s feeds thoughts This week was all about the ‘loop’ and Fable . The Loop The best way I can describe it is: design the flowchart. Think of the deterministic flowchart on how you want your agents to work. Aim to have: more deterministic bits - this keeps things more predictable more verification bits - this is agent feedback more agent tool calls - this, on a frontier LLM, makes it perform better. The ‘loop’ is essentially: goal -> agent acts -> verifier checks -> state/memory updates -> policy decides next action -> repeat/stop/escalate now the specific implementation of this - will differ based on what you’re working on. Fable Fable capabilities are absolutely insane, I tried it myself and it is entirely worth it for you to spend 2 minutes looking at this. There are a few projects that I fire up a new model into to see what’s it gonna do. A project I wanted to build was a way to teach and demonstrate ‘spin’ in table tennis, every frontier model before Fable fumbled hard. But Fable outshined them with ease: https://srijanshukla.com/artifacts/spin-lab/ If you personally did not experience a big shift in capability, you are probably not asking it a complex enough or ambitious enough task. Fable came, and Fable was taken away. The United States Government(USG) was reported with a jailbreak or sorts - which Anthropic considers not significant. The USG anyway banned Fable just after few days of release. Big drama. Fable was very pricey $$$$ Hence, people developed some patterns of work on those few golden days of Fable being available. - use Fable as planner/architect/taste/spatial/front-end judge. - use GPT-5.5/DeepSeek/Kimi as executor/worker. Other things Openrouter released their Fusion feature as a model on their platform, accessible via API. Fusion is basically council-of-LLMs pattern - providing results that can rival the frontier Fable 5 solo. Google Open Knowledge Format - https://github.com/Goo
