LLM Coding Showdown: Opus 5 Criticized for Overthinking, GPT-5.6 Wins
prasenx · x · 2026-07-31
A developer shared their hands-on experience comparing several frontier LLMs for coding tasks:
- Claude Opus 5: Accused of overthinking everything, making simple tasks take forever. It only performed exceptionally well on games and Three.js; otherwise, it was mid to trash and burned through tokens rapidly.
- GPT-5.6 Sol & Fable 5: Noted as being much better at directly shipping functional code.
- Grok 4.5: Has become their daily driver for search and random tasks, while they wait for the 4.6 release.
