Hi Transformers folks,

I wanted to share a small but unusual language-runtime project that may still be relevant to a broader ecosystem question, even though it sits far outside the usual Python/GPU dense-model path.

We built a public demo line called Engram and deployed it on a commodity ESP32-C3.

Current public numbers:

  • Host-side benchmark capability

    • LogiQA = 0.392523
    • IFEval = 0.780037

  • Published board proof

    • LogiQA 642 = 249 / 642 = 0.3878504672897196
    • host_full_match = 642 / 642
    • runtime artifact size = 1,380,771 bytes

Important scope note:

This is not presented as unrestricted open-input native LLM generation on MCU.

The board-side path is closer to a flash-resident, table-driven runtime with:

  • packed token weights
  • hashed lookup structures
  • fixed compiled probe batches
  • streaming fold / checksum style execution over precompiled structures

So this is not a standard dense model represented in a familiar inference stack. It is closer to a task-specialized language runtime whose behavior has been crystallized into a compact executable form under severe physical constraints.

Repo:
https://github.com/Alpha-Guardian/Engram

Why I’m posting here is that Transformers sits at the center of how model definitions propagate across the open ecosystem.

What I’d be curious about is whether systems like this should be thought of as:

  • completely outside the normal model-definition family
  • an extreme endpoint where some language capability is no longer best represented as a general dense model
  • or an early sign that future language systems may include both general model definitions and highly specialized executable forms for certain capability slices

If this direction is relevant to the broader ecosystem conversation, I’d be glad to compare notes.

Fix Plan

To address the issue of optimizing the Engram project for better performance and smaller runtime artifact size, we can consider the following steps:

  • Optimize token weights and hashed lookup structures:
    • Use techniques like quantization and pruning to reduce the size of token weights.
    • Implement a more efficient hashing algorithm to reduce the size of lookup structures.
  • Improve streaming fold and checksum style execution:
    • Use a more efficient streaming algorithm to reduce computational overhead.
    • Consider using a more efficient checksum algorithm to reduce computational overhead.
  • Reduce the size of precompiled structures:
    • Use compression algorithms to reduce the size of precompiled structures.
    • Consider using a more efficient compilation algorithm to reduce the size of precompiled structures.

Example Code

Here is an example of how you can implement quantization and pruning to reduce the size of token weights:

import numpy as np

# Load token weights
token_weights = np.load('token_weights.npy')

# Quantize token weights to 16-bit integers
quantized_token_weights = np.round(token_weights * 32767).astype(np.int16)

# Prune token weights to reduce size
pruned_token_weights = quantized_token_weights[:, :1000]

# Save pruned token weights
np.save('pruned_token_weights.npy', pruned_token_weights)

Verification

To verify that the fix worked, you can compare the size of the runtime artifact before and after applying the optimizations. You can also measure the performance of the Engram project before and after applying the optimizations to ensure that the optimizations did not introduce any significant performance regressions.

Extra Tips

  • Consider using a more efficient programming language and compiler to reduce the size of the runtime artifact.
  • Consider using a more efficient data structure to store token weights and hashed lookup structures.
  • Consider using a more efficient algorithm to perform streaming fold and checksum style execution.
