Pick one — models revealed after.Both summaries are AI-generated. Claude Fable 5 and GPT-5.6 Sol autonomously produced full music videos from a song and $100 budget, with GPT-5.6 Sol costing 4x less in LLM tokens ($3–4 vs. $16–25) despite similar output. This means GPT-5.6 Sol can run longer agentic loops or tighter budgets without token cost blowing up your cloud bill, while still handling complex multi-tool workflows like mixed video pipelines. If you're shipping agents in production, GPT-5.6 Sol's token efficiency directly lowers your per-task cost and widens the range of viable use cases. Claude Fable 5's LLM token cost alone was $16.99 to $25.05, around 30-40% of the total run cost, greatly exceeding GPT-5.6 Sol's token cost; this significant cost disparity matters for production because it directly impacts the total cost of shipping AI-generated music videos, potentially making Claude Fable 5 less viable for budget-sensitive applications.
