Gpt Weekly Limit Estimation

GPT Weekly Limit Estimation

[Edited by Codex: 019bebf3-c7d3-75c1-b096-339970e5cbc0 2026-01-23]

Estimate weekly limit as:

weekly_limit_usd = cost_so_far_usd / percent_used

This skill intentionally does not re-implement token counting. It depends on two base skills:

• compute-token-cost (ground truth token+cost computation)
• pull-pricing (live pricing snapshots + append-only historical JSONL)

Quick Start

# 0) Pull live pricing snapshot (writes snapshot JSON + appends pulled_data.jsonl)
python ~/.claude/skills/pull-pricing/run_pull_pricing_and_log.py

# 1) Extract one billing-week window (OpenAI resets weekly at 14:47 local time)
python /Users/sotola/swe/token-computation/extract_codex_week.py \
  --src ~/centralized-logs/codex/sse_lines.jsonl \
  --dst /tmp/billing_week.jsonl \
  --start "2026-01-15 14:47" \
  --end "2026-01-22 14:47" \
  --assume-sorted-by-t

# 2) Compute cost using a specific pricing snapshot (pick the newest snapshot file)
cd /Users/sotola/swe/token-computation && \
  python compute_token_costs.py \
    --codex /tmp/billing_week.jsonl \
    --claude ~/centralized-logs/claude/sse_lines.jsonl \
    --pricing-snapshot ~/centralized-logs/pull-pricing/snapshots/<pick-newest>.json

Critical Knowledge

Billing week boundary

OpenAI’s weekly reset is Thursday 14:47 local time (confirm on the dashboard if unsure).

• Treat the reset timestamp as the exclusive end of the window.
• Extract [start, end) where start = end - 7 days.

Why CodexMonitor can be wrong

CodexMonitor-style “delta of total_token_usage” can overcount when totals reset or multiple runs mix.

Ground truth is:

• Codex/OpenAI: sum turn.token_count.info.last_token_usage and dedupe repeated snapshots per sid.
• Pricing: use a saved snapshot (don’t hardcode discounts).

Weekly limit estimation

If OpenAI dashboard shows you’ve used X% of your weekly limit:

cost_so_far = 147.20   # from compute_token_costs.py output
percent_used = 0.28    # from dashboard
weekly_limit = cost_so_far / percent_used
print(weekly_limit)    # 525.714...
