GPT-4 Technical Report
OpenAI, Josh Achiam, Steven Adler, Sandhini Agarwal et al. · OpenAI (Technical Report) · 2023
Abstract
OpenAI's report on GPT-4, notable as much for what it withholds as what it states: architecture, data and training compute are explicitly not disclosed. What it does document is capability across professional and academic exams, accepting images alongside text, and a long safety section covering the risks found during evaluation and the mitigations applied before release.
Why it matters
The moment frontier reports stopped being reproducible science and became capability-and-safety disclosures. Worth reading alongside an open report like DeepSeek's or OLMo's to see exactly which questions each one refuses to answer.
