OpenAI released a Prompt Guide to go along with the new GPT 5.4 model! {from the guide): Where GPT-5.4 is strongest GPT-5.4 tends to work especially well in these areas: - Strong personality and tone adherence, with less drift over long answers - Agentic workflow robustness, with a stronger tendency to stick with multi-step work, retry, and complete agent loops end to end - Evidence-rich synthesis, especially in long-context or multi-tool workflows - Instruction adherence in modular, skill-based, and block-structured prompts when the contract is explicit - Long-context analysis across large, messy, or multi-document inputs - Batched or parallel tool calling while maintaining tool-call accuracy - Spreadsheet, finance, and Excel workflows that need instruction following, formatting fidelity, and stronger self-verification Give it a try and share what you think of the new 5.4 model (nobody seemed to like 5.2 much🙃)
