Artifact

Same brief, other models

Scroll sideways. Each run had its own runtime and limits — compare the artifacts, not a score.

Automated checks

Automated checks of the stored HTML file, without running it in a browser. Details are the runner’s German originals. Format and presence checks say nothing about whether the result fulfils the brief.

2 render and interaction checks were not run. Recorded reason: “Sandbox not available — rendering skipped”.

Evaluation

Deterministic score
No score — only the format was checked, not the result
Judge
not published for this run

WhyThe v2 judge record of this run names the tested model as its own judge and lists no criteria. Its score is therefore not shown — nor the combined v2 score, which blends that judge in.

Limits of this run

  • 2 render and interaction checks were not run. Whether the artifact works in a browser was not checked automatically.
  • No executed check with a shown result evaluates what was built.
  • No judge evaluation is published for this run. There is therefore no quality verdict — only the automated checks listed here.
  • Token limit 16000: other runs of this task were recorded with 8192, so this run is not like-for-like with them.
  • The settings shown are nominal: this runtime was called without them, so they were not enforced.
  • Not fully reproducible; the recorded reason is listed under “Environment”.

Task

Brief (turn 1)
Baue als EINE einzelne HTML-Datei (kein Framework, kein externes Asset, keine externen Fonts) einen bildschirmfüllenden, animierten Hintergrund im Stil Biolumineszenz in der Tiefe: tiefes Petrol bis Schwarz, darüber schwebende, leuchtende Schlieren in Türkis, Cyan und einem kalten Magenta, die sich träge wie Quallen bewegen. Geheimnisvoll, ruhig, kühl. Helle, klare Wortmarke. für die Startseite eines Tiefsee-Forschungsprojekts. Anforderungen: - Ein atmosphärischer, animierter Verlauf (Aurora / Mesh-Gradient / fließende Farbwolken), der den gesamten Viewport füllt und sich langsam, organisch bewegt — via CSS-Animation oder Canvas, selbst erzeugt. - Ruhige, hochwertige Bewegung mit weichem Easing; die Farben durchmischen sich stimmig, kein hartes Flackern, keine sichtbaren Kanten oder Banding-Streifen. - Darüber eine knappe, zentrierte Bildmarke: „Abyssal" als elegante Wortmarke plus eine kurze, ruhige Zeile darunter — gut lesbar über dem bewegten Grund. - `@media (prefers-reduced-motion: reduce)`: Bewegung anhalten, ein ebenso schöner statischer Verlauf bleibt. - Bildschirmfüllend ohne Scrollbalken, kein horizontaler Overflow.

From the task seed (German original); the actual prompts add output-format instructions and other wording.

Model The runner’s model identifier maps to Claude Fable 5 in the agi.jetzt register (verified mapping).

What this is evidence for

Not an AGI measureThis run shows one thing: what a model built as a single HTML file from a precise brief. It says nothing about general intelligence.Checked automatically in this run: 2 format checks passed — no check of the result · 2 render and interaction checks not run.

What the task set is meant to measure
  • Artifact creation from a precise brief
  • Instruction following
  • Static checks of the file (no functional test)
Not in its scope
  • General intelligence / AGI
  • Agents and tool use
  • Multimodal input
  • Retrieval
  • Conversation

Published and unpublished runs

4 of 15 verified v2 runs of this task are published. 4 of the 6 models with recorded runs have a published run.Not published: Claude Haiku 4.5 (3 runs; 0 of 2 format checks passed); GPT-5.6 Sol (3 runs; 0 of 2 format checks passed).In addition, 1 published run has no selection record (not part of the v2 import).Source: the selection records of the published runs. They count the task across its variants and know only models with at least one published run.

Selection
Curated import: 6 of 18 verified v2 runs of Claude Fable 5 are published. The selection is not a representative overall result; what is recorded for the model’s other runs is listed below.Recorded checks of all verified v2 runs of this model, per task (across task variants). The checks differ per task, so the tasks are not comparable with each other.
