slvDev's esp32-ai (MIT, 1.2k stars) runs a TinyStories-trained model on an ESP32-S3 with 512KB SRAM, 8MB PSRAM, and 16MB flash, printing generated text to a small wired screen (GitHub). The trick is a Per-Layer Embeddings architecture parking a 25M-parameter lookup table in flash while only the compute core lives in fast SRAM, quantized to 4 bits at 14.9MB total. Plain C on Karpathy's llama2.c. It cannot answer questions or follow instructions, only writes short stories, and that honest framing is exactly what makes the memory-hierarchy trick worth studying.
