## Description

## Summary

Starting ~June 16, my ChatGPT Plus Codex budget drains in 2–3 prompts on `gpt-5.5`

, where the same model/plan/app previously gave 20+ prompts. My Codex session logs (`token_count`

/ `rate_limits`

events) show the **limit-% consumed per token has increased roughly 10–20×**, with no change on my side — prompts are actually *smaller* now and reasoning tokens are near zero.

## Environment

- Codex desktop app, Windows 11
- Model:
`gpt-5.5`

,`service_tier = "default"`

- Plan:
`plus`

(confirmed in`rate_limits.plan_type`

) - Config unchanged across the regression window

## Evidence — same plan, same model, same app

**June 12 (working — 20+ prompts/day):**

| Prompt | Input tokens | Reasoning tokens | Primary limit % |
|---|---|---|---|
| 06:08 | 22,334 | 488 | 2% |
| 06:09 | 52,161 | 1,130 | 3% |
| 06:51 | 57,112 | 3,645 | 9% → 11% |
| 06:54 | 79,961 | 5,125 | 15% → 16% |

→ ~57K-token prompt with 3.6K reasoning ≈ **1% of the 5h budget**

**June 18 (broken — 2–3 prompts):**

| Prompt | Input tokens | Reasoning tokens | Primary limit % |
|---|---|---|---|
| 07:22:27 | 18,910 | 152 | 18% |
| 07:22:30 | 20,480 | 0 | 45% |
| 07:22:34 | 23,469 | 48 | 57% |
| 07:22:43 | 23,631 | 0 | 68% |
| 07:22:50 | 23,839 | 0 | 77% |

→ ~20K-token prompt with **zero** reasoning ≈ **10–27% of the 5h budget**

**Per-token limit cost changed ~10–20×.** Smaller prompts, near-zero reasoning, yet each consumes 10–20× more of the 5-hour budget than a 57K-token xhigh prompt did on June 12.

## What I ruled out (verified from logs)

**Not reasoning effort:** reasoning tokens are 0–152 today vs 3,645–5,125 on the good days.**Not prompt/context bloat:** input tokens dropped from 57K–80K to 18K–23K.**Not my config:**`model_reasoning_effort`

was already`high`

/`xhigh`

on the working days (June 12–15). xhigh gave 30–40+ prompts on June 3, 12, 13, 15.**Not the weekly cap:** secondary window is only at 12%. The 5-hour window is the one draining.

## Corroborating timing

OpenAI status page shows an active incident ongoing ~2 days (since ~June 16), which matches exactly when my usable prompt count dropped from ~9 sessions/day to ~4.

## Ask

Was the Plus-tier `gpt-5.5`

rate-limit budget reduced or the per-token weighting changed around June 16? If intentional, what's the new budget? If not, can it be investigated?

## Session log references

- Good day:
`rollout-2026-06-12T09-07-36-019eba71-5c57-70d0-a8fa-aa999731e9ff.jsonl`

- Bad day:
`rollout-2026-06-18T10-22-14-019ed99b-ea9d-7fa1-a86b-dca4e55a8e3e.jsonl`

- Rate-limit data is in
`token_count`

events with`rate_limits`

payload (fields:`primary.used_percent`

,`secondary.used_percent`

,`plan_type`

,`resets_at`

).
