Ramon Astudillo: death of the pelican test >That connection has been mostly severed now. The GPT-5.6 and Claude Fable 5 pelicans are outclassed by GLM-5.2, and much as I love GLM I don’t think that’s a Fable-class …
“The most interesting Fable tip I've heard so far is to let the model use its own judgement as much as possible I told it "For all coding tasks use your judgement to decide an appropriate lower power model and run that in a subagent" and it seems to be savin…”

Ethan Mollick: What if the model is the router? I think people underestimate the ability of frontier models now, but especially in the near future, to delegate work on their own as needed to dumber, cheaper model…
Simon Willison: That paper predates Fable - I'd love to see them re-run that experience to see if Fable is a meaningful improvement My hunch is that it does, but data is better then hunches!
“I interviewed Cat Wu and Thariq Shihipar from the Claude Code team at the AI engineer World's Fair a couple of weeks ago - the video is now out, so I've published an annotated transcript of our conversation simonwillison.net/2026/Jul/21/...”

Luis Villa: @simonwillison.net no mention one way or the other in your commentary: I assume not a reproducible build, so no way to know if that code matches what is actually running?
Simon Willison: I didn't see anything that would help verify if it matches the xAI binary
