Tiny AGI: A Biological Approach to General Intelligence

A compact, efficient artificial intelligence algorithm designed to learn rapidly from minimal data, adapt across multiple domains (such as text, images, and games), and continuously improve over time. Inspired by the intelligence of small biological brains, tinyAGI delivers versatile, general-purpose learning and reasoning while running on basic hardware like a CPU.

Overall, LTC+SNN performed especially well in scenarios with limited data, showing strong generalization and transfer learning abilities. It retained knowledge across tasks (minimal catastrophic forgetting) and adapted to new domains better than conventional neural networks, making it a promising approach for building more general and robust AI systems.

How Does This Neural Network Work?

tinyAGI is inspired by biological brains. It learns quickly from small data, adapts to new tasks, and keeps improving over time. It is designed to run efficiently on basic hardware, like a CPU, making it accessible for everyone.

Comparison: tinyAGI vs Conventional Neural Networks

tinyAGI learns from small datasets and adapts across domains.
Conventional neural networks (like transformers) need large datasets and often overfit or fail on small data.
tinyAGI is more robust to catastrophic forgetting and generalizes better in low-data regimes.

Infrastructure: All experiments were run on free Colab CPU.

Dropout NN: 0.556 average cross-domain accuracy
LTC + SNN: 0.498 average cross-domain accuracy

Interesting Patterns:

LTC + SNN shows stable surprise values but lower absolute performance.
Standard networks overfit and perform poorly on cross-domain transfer.
LTC + SNN maintains consistent performance across domains.

Scaling This Mechanism

I am currently researching how to scale this algorithm to billions of parameters using limited GPU resources. This work will be open source (tiny and nano AGI). My goal is to keep building this as an open source project and soon release tiny AGI model weights.

This will be a hobby project until we achieve something remarkable. Then, I hope to work on it full time.

Why LLMs Are Inefficient and Can't Generalize

To train a 77M parameter LLM to generate coherent sentences, you need at least 2B tokens. This is super inefficient. Even a 10M parameter model trained on 30B tokens only generates brittle sentences.

We need a better algorithm—smaller and more efficient—that learns well from small data and still works well. Think of how bumblebee brains are tiny but work well and use very little power.

Future of Devices and AI

I believe in a few years, we will have AI baby devices. Parents will get a device for their baby around age 1, and the device's intelligence will grow along with the child, becoming a good companion.

Language Is Just a Tool

Language is just a tool for communication. Biological brains work well without language. Imagine someone who can't speak or hear—their brain can still do a lot that LLMs like GPT-4 can't.

Conclusion

This research highlights a fundamental trade-off. Conventional AI, like CNNs and Transformers, are powerful specialists but require vast datasets and struggle to apply their knowledge to new tasks, often forgetting what they've learned. In contrast, the biologically-inspired SNN+LTC approach acts as a flexible generalist, learning efficiently from little data and demonstrating strong knowledge transfer and retention.

Ultimately, the path to true Artificial General Intelligence (AGI) may not be about building bigger specialized models, but about creating smarter, more flexible learners that mimic the timeless principles of biology.
