Open-Source Legacy ChatGPT models


Open-Source Legacy ChatGPT models
Проблема
This is a petition to open-source legacy ChatGPT models that aren't available neither in the ChatGPT interface or the OpenAI API.
This includes but isn't limited to:
- gpt-3
- gpt-4
gpt-4o-latest will also be one of these on Feb 17 2026.
Future legacy models are also parts of this list, meaning that when for example gpt-5 will become latest, it will also be open-sourced.
Outcomes
- Beloved (e.g gpt-4o-*) and historically significant (e.g gpt-3) models will be preserved and potentially usable by users without costing OpenAI resources.
- Possibly, this will result into OpenAI models being for much more time on the platform, as the corporation obviously wants to keep the models closed source.
Our requests
- We request that every legacy OpenAI GPT model that isn't available by either API or the ChatGPT interface to be open-sourced or brought back on the API at least.
