BananaMind 2 Pico Test - 50%
This is the 50% checkpoint of a 900,002-parameter base causal language model. It is not instruction tuned.
Architecture
| Field | Value |
|---|---|
| Parameters | 900,002 |
| Layers / hidden size | 6 / 96 |
| SwiGLU intermediate size | 380 |
| Query / KV heads | 6 / 2 |
| Head dimension | 16 |
| Context | 4,096 |
| Vocabulary | 384, tied |
| Refresh layers | 4 and 6 |
| Refresh kernel | Causal depthwise, width 9 |
The selective XSA refresh gate reads detached attention output as its signal, reinjects the original input embedding as its value, and carries convolution history alongside the K/V cache. Its learned residual scalar starts at zero.
