iskander · x · 2026-08-01
A developer shared practical experiences with different AI coding models, noting that GPT-5.6 (Codex) performs better in maintaining and making gradual additions to existing codebases.
Additionally, the developer found the model capable of autonomously exploring different paths to solve research problems and spontaneously generating highly informative figures and summaries. Meanwhile, Claude shows an absolute advantage in greenfield one-shot coding.
