Your AI and this story

  • GPT-6 Astra145 days after its cutoff
  • Claude Opus 5.584 days after its cutoff
  • Gemini 4 Hydrogen175 days after its cutoff
  • Grok 4.7114 days after its cutoff

None of these four assistants can know about it. The closest, Claude Opus 5.5, stops 84 days before it.

Key facts

  • Community-made, not Anthropic-official. No Anthropic account or staff involvement was found (as of 2026-09-29)
  • Song lineage: MusicPerson (Udio, Apr 2024) → osmarks’ ‘P(doom)’ (Udio, 2024-11-09; lyrics partly suggested by a Claude model) → deckard’s ‘Claude-Pop’ Suno version on X (2026-09-09, ~723k views)
  • Opus 5.5 does not generate video: it writes code (p5.js/p5.brush, three.js, canvas, Remotion, Blender Python) that is rendered frame by frame in headless Chrome and encoded with ffmpeg
  • JohnHeibel/PDoomVideo: two Claude Code generations; ‘Everything in this repository was generated by the model’; human direction was only ‘use the Clawd character’ and ‘give each lyric interesting visuals and transitions’. ~1.5k GitHub stars, 160 forks by 2026-09-29
  • @donaldjewkes (2026-09-23): 5-minute dictated prompt, ~12 hours autonomous work, Seedance 2.5 + fal image models + ElevenLabs as tools; ~3.6M views, 10.3k likes on X
  • Follow-ups within a week: Pleometric (~670k views), mexicat three.js karaoke version (~1.4M views; repo ~1.9k stars), ‘Nothing Went Foom!’ accelerationist answer (~670k views), ‘Let’s Lower the P(doom)!’, ‘P(bloom)’, ‘I’m Lowering My P(Doom)’, ‘Still Upping My P(doom) Vol. II’, Korean and J-rock covers, a GPT-6 Astra-animated version
  • Recurring lore: Clawd (Claude Code’s pixel-crab mascot) as the singing AI, a nervous human Researcher, the P(doom) meter, the smiley-mask shoggoth, the basilisk, paperclips, ‘What did Ilya see?’

What happened

  • 2024: “P(doom)” was written collaboratively. MusicPerson made the first verse and chorus on Udio (April 2024). osmarks added verses on 2024-04-17 with input from the EleutherAI Discord, then finished the song on 2024-11-08/09 with help from a Claude model on the outro and final chorus. It was released on YouTube on 2024-11-09. The lyrics pack about two years of AI-safety Twitter and LessWrong in-jokes into one pop song.
  • 2026-09-09: deckard (@slimer48484) posted “Claude-Pop - I’m Upping My P(Doom)”, a new Suno rendition. osmarks’ page calls it the “‘Claude-Pop’ version from alternate Suno song variant”. It spread on AI Twitter (about 723k views; people said it was “stuck in my head”).
  • 2026-09-22 (Opus 5.5 launch day): John Heibel posted a hand-painted Clawd music video for that audio: “Claude Opus 5.5 has the best visual design of any model I have tested so far”. It got about 2.7M views, and he open-sourced the code as PDoomVideo. Opus planned the video itself (STORYBOARD.md), briefed parallel subagents (ANIMATION_GUIDE.md) and wrote every scene in p5.js.
  • 2026-09-23: @donaldjewkes posted a K-pop-styled remake: “I spoke to my computer for 5mins, claude worked for 12 hours, and I woke up to this”. It is the genre’s biggest hit (about 3.6M views). His published prompt became a template that Pleometric, makevoid and others reused.
  • 2026-09-23 to 09-29: remixes, restyles and answer songs followed, all made with Opus 5.5: mexicat’s three.js karaoke version, a Nolan pastiche and a Barbie answer, a Korean watercolor MV, a J-rock voxel cover by an imaginary “Singularity Band”, “Let’s Lower the P(doom)!” (pro-safety), “Nothing Went Foom!” (pro-acceleration), “P(bloom)”, “Still Upping My P(doom) Vol. II”, and original “Claude Anime Pop” songs. Other Opus 5.5 music videos from the same week include A.J.’s JavaScript-synthesized pop-punk and rap singles, the “Absolutely Right (Crab Walk)” rap (music also by Claude), josh’s “Functional Emotions” song, and Brad Mills’ “Stroke of a Pen”.
  • Full list, production pipeline and lore: see docs/ai-culture/claude-pop.md and docs/ai-culture/lore.md.

Why it matters

It is the first widely noticed genre of AI-directed media. The model is the director, animator and software engineer, while the music (Suno/Udio) and the lyrics are mostly older and human-written. The videos are code-rendered, not generated by a video model, so every one is reproducible and forkable, and PDoomVideo alone had 160 forks within a week. The genre also turned an AI-risk meme into mainstream entertainment and a battleground: safety advocates (PauseAI/ControlAI links in “Let’s Lower the P(doom)!” and Patryk Perduta’s version) and accelerationists (“Nothing Went Foom!”) both used Claude-made videos to argue their side.

What is disputed or not yet verified

  • “Made by Claude Opus 5.5” usually means the visuals and code. The song audio is Suno (deckard) and the lyrics are from 2024 (humans + an older Claude). Exceptions where the music is also model-made include “Absolutely Right (Crab Walk)”, A.J.’s singles and the Opus 5.5 fugue.
  • View counts are from 2026-09-29 and come from X’s public embed data (fxtwitter) and YouTube watch pages.
  • X’s AI-written trending summaries mention a Nick Cammarata reaction and ‘super-propaganda’ concerns. We could not read those posts, so these are low confidence.
