Developer trains a small AI on a single RTX 3080 Ti gaming GPU to 'play' Pokémon Red
Developer stmonty trained a small AI model with 12.5 million parameters on a single RTX 3080 Ti to learn how to play Pokémon Red. The model, based on world model research, learned button functions by predicting compressed screen summaries without initial reward signals. After fine-tuning, the AI successfully selected a starter Pokémon in over half of its test runs, demonstrating the viability of small, locally trainable models for specific tasks.
- ▪The AI model contains approximately 12.5 million parameters and was trained on a single consumer-grade RTX 3080 Ti graphics card.
- ▪The training process utilized 42,382 grayscale frames from over 1,000 short game runs, including random button presses to ensure comprehensive learning.
- ▪The model uses a reward-free initial training phase where it learns to predict compressed screen summaries of 192 numbers rather than full images.
- ▪Following fine-tuning, the model successfully selected a starter Pokémon in 52 out of 100 runs, significantly outperforming random button presses.
- ▪The developer noted that small prediction errors can compound, which initially caused the model to fail in selecting a Pokémon before adjustments were made.
