$100 AI Music Video: Claude Fable 5 vs. GPT-5.6 Sol
Researchers compared the autonomous capabilities of Claude Fable 5 and GPT-5.6 Sol by tasking them with directing a music video using a $100 budget. The models demonstrated different approaches to tool usage, with GPT-5.6 Sol showing more versatility in mixing video generation pipelines.
Why it matters
This experiment highlights the evolving autonomous capabilities of frontier AI models in complex, multi-step creative workflows.
All posts video comparison agents $100 AI Music Video: Claude Fable 5 vs. GPT-5.6 Sol We gave Claude Fable 5 and GPT-5.6 Sol the same song, a budget, web search, and local ffmpeg, then let each autonomously direct a music video.
A few readers of our last build-off said they wanted to see how tool use actually varies between models, so we gave frontier-level models an open-ended, long-horizon task where each model decides on its own what to research, what to generate, and how to edit. We log every tool call, so you can see exactly how each one worked (full transcripts below).
We ran two models, Claude Fable 5 and GPT-5.6 Sol , each at two budgets ($25 and $100), for four runs total. Every run got the same song (Bruno Mars and Mark Ronson's "Uptown Funk"), a short text description, and a time-stamped lyric transcript.
