Hands-on with Latest Coding Models: GPT-5.6 Regresses, Grok-4.5 Wins
sergeykarayev · x · 2026-08-05
A developer shared their team's hands-on experience with the latest generation of coding agent models, suggesting the new upgrades aren't unequivocally better:
- Claude 3.5 Opus / Fable 5: A level above others in thoroughness, but overkill for most daily tasks and quickly exhausts usage limits.
- GPT-5.6 Sol: Often worse at coding than GPT-5.5, prompting some team members to downgrade, though it's a better writer.
- Grok 4.5: The author switched to this as their daily driver due to its speed.
The author questions whether we've reached a plateau of "good-enough" coding abilities.
