haider1 · x · 2026-07-30
OpenAI engineer Thibaut Sottiaux hinted at a new Codex update shipping tomorrow, noting that this week's theme is making intelligence too cheap to meter.
Based on OpenAI's recent 20% serving cost cuts and 15% token efficiency improvements, AI commentator Tibo (@tboutot) made three key predictions for the update:
- Massive Inference Speedup: Running a GPT-5.6 model on Cerebras at 750 tokens/s, potentially introducing a new Fast mode.
- Efficiency and Usage Limit Upgrades: Further improvements to model efficiency and relaxed usage caps following recent optimizations.
- Lightweight Model Release: Potential launch of a new GPT-5.6 spark-style model.
