LLM Foundry on a tiny model: the stack still does the heavy lifting

This run was intentionally small-model and intentionally boring: no cloud API, no fake genius, just a tiny local model plus a better stack around it.

LLM Foundry with Qwen2.5-0.5B is the version that makes the point most cleanly: the model itself is small, but the workflow around it can still be decent.

What the proof showed

From the local proof run:

• Benchmark pass rate: 50%
• Reasoning: 60%
• Coding: 100%
• Tool + memory: 100%

The demo also showed memory compression and retrieval in action. The exact lesson is simple: if wording changes, semantic retrieval is a lot better than brittle keyword matching.

Why I care

The whole point of this layer is not to brag about a bigger model. It is to make a small model more usable:

• it can recover relevant context
• it can shrink messy transcripts into working memory
• it can be checked instead of hand-waved

That is the part around the model that turns a chat toy into something that can remember, recover context, and be tested.
