A 7 GB 27B Model Lost to My 17 GB Default
A 6.66 GiB ternary 27B model fit my RTX 5090, but it lost the default slot. File size is only the first local model-selection gate.

Your Agent's Audit Trail Cannot Be Retrofitted
Agent logs show activity. They do not prove the outcome an agent claimed. Here is the verification layer I added after an agent reported two false dones.

My Agents Have to Prove What They Did
I extracted the claims ledger that runs my agent operation into showwork. Falsifiable claims, deterministic checks, and an exit gate that refuses a false done.

Why production AI is moving to open weights
I tested a local-first writing pipeline on an RTX 5090. Gemma 4 writes the draft, deterministic checks catch errors, and frontier QA decides what ships.

Q4km vs Q5km: Q4_K_M vs Q5_K_M
q4km vs q5km is Q4_K_M vs Q5_K_M in GGUF. Pick by VRAM headroom, quality risk, and CPU fallback. Use the free quant tool before download.

I Raised the QA Bar on Blog Infographics
Blog charts need correct labels. I tightened layout geometry, char budgets, claims checks, and vision logs so a bad PNG cannot ship quietly.

I Rebuilt 5,383 Embeddings After a Dimension Change
I moved a vault search index from 1,536 to 768 dimensions. Here is why I rebuilt all 5,383 chunks instead of mixing vector spaces.

Pin Your Local LLM Context Size Before You Build a Router
Changing context size can reload a local model before every request. A measured RTX 5090 sweep shows why context belongs in the routing key.
