Claude 4 Outperforms GPT-5 in Independent Reasoning Benchmarks

Anthropic’s Claude 4 achieved a 4.3 percent lead over OpenAI’s GPT-5 in Hugging Face Labs’ multi-step reasoning tests. Evaluations covered structured logic, code analysis, and chain-of-thought tasks across 21 datasets. Experts said Claude 4’s improvements stem from better alignment and long-context window optimization. Anthropic announced broader API access for enterprise researchers next month, signaling growing competition in advanced language model reasoning and governance domains.
