OpenAI's GPT-5.6 Sol and Anthropic's Claude Fable 5 Turn a Single JSON Prompt Into Full Video on First Try

Two of the industry's leading models, OpenAI's GPT-5.6 Sol and Anthropic's Claude Fable 5, each generated a complete video from a single structured JSON prompt on the first attempt, with Sol reaching a finished result faster. The head-to-head demonstration, rendered through Higgsfield AI's Seedance 2.0 video engine, highlights how quickly large language models have moved from producing text and code to orchestrating end-to-end multimodal creative workflows.
