Speak while you can.
Available closed models are paired with a countdown and a chat interface from their era.
INTERACTIVE MUSEUM
Ancient AI
Chat with older AI models in the interfaces of their time.
An interactive museum of language models: talk to available specimens through the interfaces of their era, watch the countdowns for closed models, and explore a permanent collection of open weights.
A museum you
can talk to.
WHY I BUILT IT
“Some of the models I used every day simply vanished from the products they once lived in.”
The experience pairs a museum catalogue with working conversations. GPT-3.5 Turbo, GPT-4 and GPT-4o have ChatGPT interfaces from 2022, 2023 and 2024. Closed models carry a countdown; open-weight models belong to the permanent collection. In Memoriam records the models that can no longer answer.
Open weights, preserved.
A separate collection for models whose weights can be kept. GPT-2 is currently listed as coming soon.
A record of the departed.
Models that can no longer answer retain their place in the catalogue.
