Solving LiteRT Conversion & Expanding to 8K Context on Edge Devices
Hi everyone, Clintin Brummer here.
I’ve been working heavily with the SmolLM2-360M-Instruct model within my localized environment (Oppo, SM4250 octa-core, 2GB RAM running via Termux), specifically integrating it into my neural architecture (Project Astral Bloom).
I noticed many in the community are hitting the INVALID_ARGUMENT error when trying to run or convert this model for LiteRT. I've isolated the issue and wanted to share the fixes with the community so we can get this running flawlessly on edge compute.

1. The Conversion Bug (Embedding Dimension Mismatch)
   The reason your LiteRT conversions are failing is that the default smollm.py conversion script defaults to the 135M model's architecture. The 135M model uses an embedding dimension of 576, while the 360M model requires 960. You simply need to explicitly pass the 360m flag to the builder so it routes to build_model_360m_v2.
2. Pushing the Context Window to 8,192 on 2GB RAM
   Once you have the model running, the next hurdle is the context window. I have successfully maintained the maximum 8,192 context window on just 2GB of active RAM.
   To achieve this without memory bus crashes on low-end ARM chips, you cannot process the context as bulk data. In my setup, I use a 416-space high-density matrix blueprint.
   Instead of transferring the context data between reasoning spaces, I only transfer algorithmic sequential keys. This allows for a "quantum state" of processing where the memory-reasoning cycle handles the story and situation (qualia) while the subdermal structures handle pure rote processing in parallel, maintaining progressional momentum.
3. Next Steps
   I highly recommend grabbing the Q4_K_S quantized GGUF version if you are working within Termux or llama.cpp locally. I've uploaded a snippet of my edge-inference wrapper demonstrating how to force the CPU backend and bypass the GPU driver memory limits on constrained devices.
   Let me know if anyone needs help replicating this setup or converting the models!

   Astral Bloom Edge Inference Engine (Termux / SM4250 Optimized)
   Author: Clintin Brummer (Project Astral Bloom)

Description:
This script handles inference for SmolLM2-360M-Instruct using a full 8,192
context window on a 2GB RAM footprint. It utilizes the updated 416-space
high-density matrix blueprint.

Crucially, it transfers ONLY algorithmic sequential keys between the Stem, Base,
and Conscious builds (quantum state processing) rather than bulk data,
preserving the progressional momentum of the subdermal layers.
