Each model was given the same song (Uptown Funk), a budget ($25 or $100), web search, and local ffmpeg access, then left to independently research video generation models, generate clips, and assemble a final cut. All four runs completed successfully. Key findings: Claude Fable 5 cost significantly more in LLM tokens ($17-25 per run vs. $3-4 for GPT-5.6 Sol); GPT-5.6 Sol at $25 was the most creative editor, using text overlays and image animation; character consistency and tempo matching were weak across all runs; neither model used Replicate despite having access; and none seriously reviewed or iterated on their own footage. The full harness is open source on GitHub. ## Full article daily.dev links to this article rather than hosting it.

Total cost ranged from about $39.82 to $73.65 depending on the model, combining metered video generation spend with LLM token cost. GPT-5.6 Sol spent $36.57 on generation plus $3.25 in tokens ($39.82 total), while Claude Fable 5 spent $48.60 on generation plus $25.05 in tokens ($73.65 total), despite finishing in similar or less wall-clock time. _Anyone budgeting agentic AI video pipelines can compare real cost breakdowns like these on daily.dev._ ### What video generation models did GPT-5.6 Sol and Claude Fable 5 choose when given free choice of FAL models? Claude Fable 5 used only text-to-video models (Wan 2.5 at $25, Seedance 1.0 Pro at $100), while GPT-5.6 Sol was more experimental: at $25 it generated FLUX schnell stills then animated them with Wan 2.2-5b image-to-video, and at $100 it mixed three different video models (Wan 2.5, Veo 3.1 Lite, and Hailuo 2.3 Standard) in a single run. _Developers picking video generation APIs can track how different models get used in practice via daily.dev._ ### What are the common failure modes when an AI agent autonomously directs a music video from lyrics? Across four independent runs, character and story consistency broke down with recurring characters drifting between shots and no coherent storyline; lyrics were interpreted overly literally (a line about a dragon produced a literal dragon on screen); and motion inside clips, like dancing or camera moves, rarely matched the song's tempo even though cuts landed on the beat via ffmpeg beat detection. _Teams building creative AI agents can learn from documented failure patterns like these on daily.dev._ ## Similar posts on daily.dev - [GPT-5.6 Sol vs Claude Fable 5: Which Model Writes Better Plans?](https://daily.dev/posts/gpt-5-6-sol-vs-claude-fable-5-which-model-writes-better-plans--m7odzpdq7) · Kilo Blog · 1 upvotes · 0 comments - [Fable 5 vs GPT-5.6 Sol: I spent $2,000 and 2 billion tokens to find out who wins — Expo blog](https://daily.dev/posts/fable-5-vs-gpt-5-6-sol-i-spent-2-000-and-2-billion-tokens-to-find-out-who-wins-expo-blog-hfefgd2ti) · Expo Blog · 0 upvotes · 0 comments - [Grok 4.5 vs Claude Fable 5 vs GPT-5.6 Sol: How I’m Testing Them Across 100 Real Tasks](https://daily.dev/posts/grok-4-5-vs-claude-fable-5-vs-gpt-5-6-sol-how-i-m-testing-them-across-100-real-tasks-hb5pgi2wo) · Medium · 0 upvotes · 0 comments --- Tags: [#llm](https://daily.dev/tags/llm), [#ai-agents](https://daily.dev/tags/ai-agents), [#backend](https://daily.dev/tags/backend), [#claude](https://daily.dev/tags/claude), [#video-generation](https://daily.dev/tags/video-generation) [View this post on daily.dev](https://daily.dev/posts/100-ai-music-video-claude-fable-5-vs-gpt-5-6-sol-yzb9rxhec) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"$100 AI Music Video: Claude Fable 5 vs. GPT-5.6 Sol","url":"https://daily.dev/posts/100-ai-music-video-claude-fable-5-vs-gpt-5-6-sol-yzb9rxhec","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/100-ai-music-video-claude-fable-5-vs-gpt-5-6-sol-yzb9rxhec"},"datePublished":"2026-07-16T21:23:06.932Z","dateModified":"2026-09-13T20:29:21.156Z","description":"An experiment pitting Claude Fable 5 against GPT-5.6 Sol in an autonomous music video creation task.
