Tokemon (https://tokemonlabs.com/ and documentation: https://github.com/leejustin/tokemon) presents 30 AI language models in the form of a Pokédex (see on Wikipedia) with stat sheets, types, evolution chains and simulated battles.
The whole thing is based on the codes of the Pokemon game, Tokemon is a bit like a Compar:IA Pokemon in pixel art.

Each “Pokemodel” comes with an icon, a number (#001 to #030), a stage of evolution and a nickname. 6 real-world statistics are available related to video game elements: context window (HP), raw reasoning (ATK), alignment and security (DEF), SP. ATK code (SP. ATK), languages covered and knowledge (SP. DEF), tokens per second (SPEED).

Individual cards add parameters, context, pricing per million tokens, and open-source “weight”.

Adventure Mode is a top-down RPG game: you choose a partner model, explore a map around it and fight against 10 trainers.
The Battle mode allows a fight between 2 to 4 models, with the blows simulating the costs of each model.

A comparison of up to 4 models is possible with all the specificities of each.

Open source, free, accountless, and unlimited.
