I honestly don't understand the assumption that there will be continued open weights models. At some point, China will regulate release of Mythos-class models or the companies making open weights models will switch to closed. There will still be open weights, just not frontier.

🤖 Anthropic's Claude Fable 5 Outperforms Peers
— Amitav Bhattacharjee (@bamitav) 11 juin 2026
Real tests show #Claude #Fable5 beating Claude Opus 4.8, Gemini 3.1 Pro, and GPT 5.5 on tough visual tasks like 3D hydrodynamics and complex physics. The gap is significant.

It really depends on the duration of your work sessions. I run loops on Codex on average for 5/10 hours. This would be incredibly expensive with Fable.

Prompt for autonomous Claude Fable with persistent HTML updates

Claude Fable can run autonomously for days.
— Matt Shumer (@mattshumer_) 11 juin 2026
This is the single highest-leverage prompt I use to stay on top of it:
"Spin up a persistent HTML page. As you work, append clear, timestamped updates with screenshots/media so I can follow along."
Literally a 10x better experience. pic.twitter.com/TKtsIALzxYClaude Fable can run autonomously for days.

Prompt and loop prevent Fable 5 token waste
By
–
prompt sets goal, context, boundaries, and verification. loop handles time: effort level, checkpoints, verifier subagents, and stop rules so Fable 5 does not burn 500k to 1M tokens unchecked.

Fable: planner/orchestrator, not direct coding tool

You should basically never use Fable for coding, but rather use it as a planner/orchestrator. Most advanced models today can implement a specification perfectly, and once done, you can send the job to Fable for
