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.
