GPT-5.1
Timeline (last 90 days)
When the agent reads the PHREEQC simulator report via a section index rather than context, GPT-5.1's accuracy drops by 11.3 percentage points.
Claude Opus 4.5 and GPT-5.1 were released in November 2025, and paired with their respective coding agent frameworks (Claude Code and Codex), they evolved coding agents from frequently error-prone to reliable enough for daily use.
According to actual test data, the Harness framework doubles the overall response speed, and applying it to the previous-generation GPT-5.1 model also improves speed by approximately 60%.
