In early October 2026 people on claude.ai started getting answers from a newer model while picking Fable 5.1, and the leak says Fable 5.5 is days away. It is not in the API yet, so we took four of the tests people ran on it and gave the same prompts to Claude Fable 5.1, the Fable you can buy today, and to Ling 3.1 Flash, inclusionAI's model that is free on OpenRouter and OpenCode. One request each. Everything runs in your browser.
An animated film in the browser: every era of art history in its own style, with an orange cat running through all of them.
Cave paintings by torchlight, Greek pottery, a woodblock sea and more, with a scrubber and chapter markers. Fable hit its output limit mid-file and was asked once to continue from the last character; no other help.
Same prompt. Title card, Egyptian reliefs, a woodblock sea; simpler shapes. First try, no edits.
The off-road scene testers gave Gemini 4 Argon and Claude Opus 5, made drivable.
Real driving: throttle, steering, suspension, mud that slows you off the trail, a cockpit camera. One read-only line added at the end for our driving bot (it exposes the jeep's position); nothing else touched.
Richer forest and a textured trail, but the jeep runs on rails: it follows the trail by itself and A/D barely turn the nose. First try, no edits.
A rope-cutting physics puzzle with an original character, stars, bubbles, cushions and spikes.
Seven levels, verlet ropes, bubbles, air cushions, spikes, a creature that watches the sweet. No edits.
Seven levels with a creature called Nomble, cardboard look. One edit: the level buttons had no click action, so the game could not be started; we added it (one line, marked in the source). Nothing else touched.
Design your own game controller in pure SVG: presets, shapes, button styles, export.
Premium shading, eight presets, three shells, pressable buttons, springy sticks, Export SVG. No edits.
Second try, no edits: it runs, but the shell is lopsided and some gradients fail. The first try did not start at all (a garbled line); it is here too, untouched: controller-lab-ling-3-1-flash-first-try.html.
