Developer Launches 'Museum of Models' to Archive and Compare 371 LLM Outputs
Developer /u/sirjoaco launched Museum of Models (museumofmodels.com), a free web tool that archives standardized prompt outputs across 371 open and proprietary LLM versions tested since May 2024. The repository includes historical response data for 93 deprecated models that are no longer accessible for public testing. As AI providers frequently deprecate older API endpoints or quietly update model weights, historical comparisons and reproducibility become nearly impossible. This archive provides researchers and developers with a preserved baseline to analyze model drift, qualitative evolution, and performance trade-offs over time. Every model output was generated under uniform testing conditions: a single-shot attempt, no custom system prompt, and a fixed temperature parameter of 0.7. The platform requires no signup and covers both accessible open-weights models and retired commercial LLMs.
## BACKGROUND
Open-weights models refer to artificial intelligence systems whose trained parameters are publicly shared, allowing developers to run and inspect them locally. The temperature parameter controls the balance between randomness and predictability in LLM output generation, where higher values yield more creative responses.
