Model Watch · OpenAI
Shuts down on 11 December 2026, along with GPT-5 Mini and nano. If you pinned to it a year ago, that's your deadline.
GPT-5 is a model from OpenAI, built in the US. The lab has put it on the retirement list. Move off it.
OpenAI released it on 7 August 2025. That date comes from the lab's own docs.
The tracker first logged the name on 4 September 2026 and last saw it on 4 September 2026.
| Lab | OpenAI |
|---|---|
| Built in | US |
| Status | deprecated |
| API model id | gpt-5 |
| Released | 7 August 2025 |
| Context window | 400K tokens |
| Max output | 128K tokens |
| Input, per 1M tokens | $1.25 |
| Output, per 1M tokens | $10.00 |
List prices per million tokens, read off the lab's own docs. Caching, batching and volume deals all cut the real number, so treat this as the ceiling. Check the source before you budget against it.
At 700 words in and 500 out, twenty times a day, that works out around $4.70 a month. Put your own numbers in, see every OpenAI price, or put it next to another model.
