Fable 5.1 is an absolute beast for game dev. I took my Opus 5 space game and told Fable to "just make it look better". It overhauled everything with a TON of detail, AND made it 2x faster 🤯
Code: t.co/tsXxzNculx
Demo: t.co/0oPiLK4638
Every pixel you see is made by AI. Fable modeled everything in Blender, generated textures with code, and in a few cases ran image models via CLI.
In mere months we'll be vibe-coding AAA graphics at this rate. Just insane.
Of course, Fable recorded and edited this comparison video too (with a little help from Opus at the end, because of the Fable outage)

A 24-hour space game got a full visual overhaul and ran 2x faster
Anshu first built The Long Silence with Claude Opus 5 in one 24-hour session, every pixel and sound made by the model. Told to 'just make it look better', Fable 5.1 remodelled everything in Blender, generated textures in code and doubled the speed. Code and demo are public.
