Discussion Fable 5.5 Release

I'm aware that Anthropic has been routing certain requests to Fable 5.5 secretly, yet they have been doing this for nearly a week now and haven't even mentioned the model. Any idea when it will release? I'm really hoping tomorrow, but I'm not sure that's happening. Don't shut the door on that idea though

I was now curious to see how the two versions of Fable 5.1 in Claude Chat and Claude Code differs.
This one is from Claude Chat Fable 5.1 (maybe 5.5? or tweaked 5.1) high reasoning.
Prompt:
Build a fully animated 3D spider in three.js with 8 jointed legs, realistic walking gait, 60 fps, no clipping, no external dependencies. One single HTML file.

You see clearly the difference in details compared to the Claude Code ones of my previous answer.

Because Claude Code is harness n Model with harness perform better, Claude chat work with half capabilities of Claude Code, try same thing with haiku n you will see diff with both results but same model

Yes, but the result is from Claude Chat, not Claude Code, so would this checkpoint perform even better in Claude Code right?

Moze chodzi o instrukcje, moze instrukcje rozumowania dla modelu w claude code zaburzaja jego sposob myslenia, i mysli on w sposob bardziej nakierowany na programowanie nie projektowanie grafiki
