 "what": "PSSA is a small non-transformer language model written from scratch in Rust, with a recurrent state-space layer, episodic memory, and a terminal dashboard.",
 "why": "117 stars, launched 68 days ago",
 "language": "Rust",
 "requirements": [
  "A Rust toolchain (inferred from the Rust implementation and the cargo commands in the README)",
  "The pssa binary built from the Sparticle62ops/pssa repository",
  "A plain UTF-8 text file to train on",
  "A terminal that supports the TUI, or use --no-tui for plain logs"
 ],
 "audience_note": "Built for ML researchers, students, and Rust developers who want to train, inspect, or extend a non-transformer language model on their own text.",
