Codex Rate Limits Discussion Thread
OpenAI Developer Community
July 2, 2026
I’ve swapped back to 5.4 medium when using Codex, and it’s been way better for my workflow. With 5.4, I rarely hit the rate limits, but the second I use 5.5, I lock myself out in two hours and max out my weekly cap in three days.
In my opinion, 5.5 medium is only marginally better for coding tasks. By just using plan mode on 5.4 and being a little more specific with my prompts, the gap disappears. For me, not getting locked out is worth way more than a 5% difference in thinking quality.
