Dosidicus
A downloadable simulation for Windows, macOS, and Linux
🦑 A transparent cognitive sandbox disguised as a digital pet squid with a neural network you can see thinking
Micro neural engine for small autonomous agents that learn via Hebbian dynamics and grow new structure
- Part educational neuro tool, part sim game, part fever dream
- Build-your-own neural network - learn neuroscience by raising a squid that might develop irrational fears
- Custom simulation engine using Numpy - No Tensorflow or PyTorch
- Most AI is a black box; Dosidicus is transparent - every neuron is visible, stimulatable, understandable.
- Starts with 8 neurons — grows via neurogenesis and rewires using Hebbian learning.
Dosidicus is a digital squid born with a randomly wired brain.
Feed him., stimulate neurons, watch him learn.
- He starts with 8 neurons.
- He rewires through Hebbian learning.
- He grows new structure via neurogenesis.
- He forms memories.
- He develops quirks.
Every squid is different. Every save file is a cognitive history.
Custom simulation engine:
- Built from scratch in NumPy
- No TensorFlow. No PyTorch.
- Fully visible neuron activations
- Structural growth over time
- Dual memory system
- Headless training mode
- Most AI is a black box: Dosidicus lets you see the mind forming.
