  "featuredClaim": "OpenAI's GPT-4.1 follows instructions so literally that old prompts may need a complete overhaul.",
  "description": "An analysis of OpenAI's newly released GPT-4.1 prompting guide, explaining how the model's literal instruction-following requires overhauled prompting habits. The article covers key changes including agentic workflows, 1M token context handling, step-by-step thinking, and OpenAI's recommended prompt structure.",
  "keyPoints": [
    "GPT-4.1 is available only via the OpenAI API, not in ChatGPT Plus, and follows instructions far more literally than previous models.",
    "Agentic workflows improve dramatically with persistence, tool-calling, and planning instructions, solving 55% of SWE-bench coding problems when properly prompted.",
    "GPT-4.1 supports a 1M token context window, with instructions best placed at both the beginning and end of provided context.",
    "OpenAI released a recommended prompt template covering role, objective, instructions, reasoning steps, output format, examples, and context."

  "supportingContext": "The article is a practitioner's six-hour analysis of OpenAI's GPT-4.1 prompting guide, translating the cookbook's recommendations into workplace tactics. Kamil Banc emphasizes that GPT-4.1's literal instruction-following marks a break from earlier models that inferred user intent, meaning legacy prompts may underperform. The methodology centers on OpenAI's own testing data, including SWE-bench results and the recommended prompt template covering role, objective, reasoning steps, output format, examples, and context. For practitioners, the actionable steps are auditing existing prompt templates, adding persistence and planning instructions, bracketing long documents with instructions at both ends, and structuring requests with the precision of a legal brief rather than a vague intern assignment.",
