OfrendaDeLosModelos. AI that can come back from dead
This is a submission for the Hacktoberfest Open-Source AI Challenge Week 4: Ghost in the Machine What I Built In August 2025, about two hundred people gathered in a San Francisco warehouse for a funeral. The deceased was an AI model, Claude 3 Sonnet. Its maker had retired it, and there was nothing else anyone could do. You can't visit a closed model once it's gone. Nobody can ask it anything…
In August 2025, a funeral was held in a San Francisco warehouse for an AI model named Claude 3 Sonnet. The model, once active, could no longer be interacted with, as it had been retired. Open-weight AI models, however, can be kept and utilized for an extended period. The creator of the funeral decided to build an ofrenda, or altar, to honor the memory of AI models, inspired by the Mexican tradition of Día de Muertos.
This virtual altar, called "Ofrenda de los Modelos," allows users to pose a question and receive answers from historical AI models. GPT-2, Gemma 1, 2, and 3 speak live, with their "ghost words" displaying the words they almost said, along with their probabilities. Gemma 4 answers on the user's device, explaining the models' intentions and composing a four-line poem, or "calaverita," for each one.
Closed models whose weights have not been released are represented by dark frames. The entire experience runs on the user's device, with no external servers, analytics, or data transfer. The project is available online and can be run in a browser without a GPU.
