| Key features | - Distributed simulation across MPI ranks
- Multi-backend execution (CPU, GPU, Browser, MPI)
- AtlasIR typed intermediate representation
- Native forward and reverse execution for training
- Retains Brian2 modelling interface
- GPU execution on Apple Metal and NVIDIA CUDA
- WebAssembly browser execution
- CPU reference and AOT compilation
| - Entity-graph spreading activation for cross-vocabulary retrieval
- Works with any LLM model
- No LLM or GPU in retrieval path
- Point-in-time and windowed recall
- Timestamped memories
- Fixed recall cost as memory grows
|
|---|
| What makes it different | - Distributed execution without sacrificing Brian2's familiar modelling interface
- Open-source with published arXiv paper and reproduction materials
- Explicit, verifiable execution plans via AtlasIR
| - Reaches answers across unrelated documents that share no keywords, where vector search scores zero
- Deterministic retrieval with no model in the path, so results never vary between queries
- Constant per-query cost regardless of memory size, even at 32,000 words
- No infrastructure to run—no vector database, cluster, or GPU needed
- Works with any model, so small local models gain the most from better retrieval
