P50 = typical speed. P95 = worst case 95% of the time. Measured by Tickerr's independent inference checks. Requires ≥10 checks to display.
TTFT over 24 hours
ⓘ Authenticated streaming API calls via native fetch. TTFT = milliseconds from request start to first streamed token chunk. Throughput = output tokens ÷ generation time. Checks run from Vercel us-east-1. Independent of the provider's official status page.

ChatGPT API not working? Common error codes
If ChatGPT's API is returning errors, the table below explains what each code means and how to fix it. If errors are widespread, check the live status above - a service incident will appear there within minutes.
| Error | What it means & what to do |
|---|---|
| HTTP 429 | Rate limit or quota exceeded - check tier limits and retry with backoff |
| HTTP 500 | Internal server error - retry once; if persistent, check status.openai.com |
| HTTP 503 | Service unavailable - check for active OpenAI incidents |
| "context_length_exceeded" | Input too long for model - truncate or summarize context |
Note: Tickerr monitors ChatGPT's status endpoint, not individual API calls. An HTTP 429 or 500 in your app may be specific to your account tier - check the rate limits page for plan-specific thresholds.
About ChatGPT status
ChatGPT is an AI chatbot and API built by OpenAI, powering millions of apps and users globally. This page tracks two independent signals: HTTP availability (is chatgpt.com reachable?) and live API inference (is the OpenAI API actually working for developers?). Tickerr makes authenticated API calls to GPT-4o-mini, GPT-4o, and o4-mini every 5–15 minutes, measuring TTFT (time-to-first-token) and output throughput. This catches model-layer failures and overloads that don't show up as HTTP outages. Common ChatGPT API errors: HTTP 429 (rate limit or quota exceeded - check your tier and add backoff), HTTP 500 (internal server error - retry once), HTTP 503 (service unavailable - check for active incidents). OpenAI's official status page at status.openai.com is typically updated within 15–30 minutes of a confirmed incident; Tickerr's independent inference monitoring surfaces issues faster.
