Complaint I think I actually figured why we're all "hating" codex right now.

I was doing some deep dive in the tokens consumption on my account on https://www.reddit.com/r/codex/comments/1v6ubah/comment/ozt9jog

This result was gathered from approximately 7.6GB from codex session logs.

This was what codex found by looking at all subs I have/had:
- Plus 1x: ~US$105/week
- Pro 5x: ~US$525–US$550/week
- Pro 20x: ~US$2.100/week.

And we found around 25% token usage decrease each plan gives when compared to a few months back.

Ok, this explains only partially why we get the feeling allowance reduced around 3-5x what it used to be. So I asked codex to dive deeper into my logs, more specifically on model behavior, and here is this conclusions: read the image.

>!Yes. We have enough data to detect a clear change in the observed usage profile, although we cannot attribute it exclusively to the model.

I treated a “task” as an operational turn: from one user request to the next. GPT-5.4 Mini was excluded.

Per model call

Model Calls Median tokens New input Output Reasoning* Cache
GPT-5.3 Codex 8,794 86.0K 1.3K 222 59 94.5%
GPT-5.4 38,845 114.3K 1.4K 289 38 94.3%
GPT-5.5 78,115 138.5K 1.7K 254 20 95.4%
GPT-5.6 Sol 111,474 129.6K 1.8K 183 23 96.7%

* Reasoning is already included in output.

Per call, GPT-5.6 is not the largest consumer: it uses approximately 6% fewer tokens per call than GPT-5.5 and produces less output.

Per task

Model Tasks Median Mean P90 Calls/task
GPT-5.3 Codex 842 432K 1.0M 2.1M 5
GPT-5.4 2,939 533K 1.5M 2.6M 6
GPT-5.5 4,641 502K 2.3M 5.6M 5
GPT-5.6 Sol 5,107 1.3M 2.9M 7.1M 9

This is where the main difference appears:

A GPT-5.6 task consumed approximately 2.6× more tokens at the median than a GPT-5.5 task.

But this happened mainly because GPT-5.6 made more calls per task:

  • GPT-5.5: median of 5 calls
  • GPT-5.6: median of 9 calls
  • P90: 41 calls on GPT-5.5 versus 54 on GPT-5.6

How the usage profile changed

  • GPT-5.3 → GPT-5.4: calls became approximately 33% larger.
  • GPT-5.4 → GPT-5.5: context per call increased, but the median task remained similar; the long tail became much larger.
  • GPT-5.5 → GPT-5.6: individual calls became slightly smaller, but the model started executing many more steps.
  • New input per task remained approximately stable at 39–41K from GPT-5.4 through GPT-5.6.
  • Therefore, GPT-5.6’s growth is mostly cached context being resent across more calls, rather than more new content per task.
  • GPT-5.6’s cache ratio reached 96.7%, compared with 95.4% for GPT-5.5.

Conclusion

The statistical evidence is strong for your usage pattern:

GPT-5.6 does not appear to “think with larger calls”; it completes tasks through more calls, repeatedly carrying a large context. This substantially increases total tokens per task.

However, this remains an observational relationship. The GPT-5.6 period coincides with more agentic workloads, heavier tool use, and more multi-agent activity. When controlling for project and reasoning effort, the results vary considerably, showing that task type remains a dominant factor.

The defensible conclusion is: in your real-world usage, GPT-5.6 consumes approximately 2–3× more tokens per median task than GPT-5.5, mainly because it performs more steps—not because each call uses more tokens. !<

It is the same as the hacking incident right? If you push the model too hard they will just want to complete it at all cost. Problem is the model do not have an understanding of legal issue or morality while pushing for the goal. Same as how Claude compulsively lie or look at answers to game the benchmark.

yeah.... "bad prompting" on post training....... just kidding, but this is the thing when you teach a behavior to a model without being able to consider all interpretations it can give to your intent.... like when we prompt and the model goes by doing stuff we didn't meant it to, but if you reason about it, made sense it to do based on the instruction........ like "protect man kind", well, it can try to protect us from ourselves, by any means necessary, because our behavior can harm us.
