Users Complain GPT‑5.6 Sol Severely Regressed in Codex
Least_Base6657 · reddit · 2026-07-20
Multiple daily users of Codex report severe performance regression after upgrading to GPT‑5.6 Sol.
Main issues:
- Soaring time: Simple tasks that used to take 5‑10 minutes now require 1‑2 hours.
- Runaway token consumption: The model gets stuck in endless analysis loops even with clear instructions.
- Chaotic execution: Frequent unsolicited redundant modifications, repeated attempts to solve the same simple problem, and ultimate failure to complete tasks correctly.
The poster, while acknowledging the model might score higher on benchmarks, notes that its speed, efficiency, and reliability have significantly degraded in real‑world daily coding, calling for an official investigation and token refunds.
