Open research on concept-bottleneck transformers. ~21M parameters, deliberate. Phase 2 runs through an agentic auto-research loop.

Five open Hugging Face datasets that test whether small (5M–100M) models actually use facts from far back in their context: recall, binding, structure, multi-hop, counting and deduction, on a length ladder from 1k to 128k tokens.
