How I Test a 30B Local Model Before I Load It
A 30B local model can fit on paper and still fail the job. This test plan checks memory, tool use, speed, and repeatability first.

Why Local LLM Benchmarks Need Power Data
A local LLM benchmark that reports only tokens per second hides the operating cost. My RTX 5090 run shows what power data adds.

VRAM Fit Is Not Runtime Support
A local model can fit in VRAM, download cleanly, and still fail before the first token. My 5090 test adds runtime support as a separate gate.

Search Old Results Before Publishing an LLM Test
An independent QA pass caught my second post about the same Ollama batch sweep. Here is the duplicate check I now run before publishing an LLM result.

Why I Test 3 Workloads Before Sizing a Local LLM
One local LLM speed number hides the work behind it. My RTX 5090 sweep shows why short generation, long context, and code need separate rates.

Test Retrieval Before Your Local LLM Writes
I make my local LLM show its source plan before it writes. The preview gate catches weak retrieval while the fix is still cheap and easy to inspect.

Why I Did Not Promote My Smaller Local Model
My smaller local model existed and ran, but it did not beat the baseline. Here is the promotion gate I use before changing a working local AI route.

Build an AI Research Workbench on Your Own GPU
Claude Science keeps data on local systems but sends selected context to Claude. Here is the owned-GPU version, with measured RTX 5090 costs.

Ollama num_batch: 256 Was My RTX 5090 Sweet Spot
I tested four Ollama settings on Gemma 4 26B. num_batch 256 delivered nearly all the speed of 512 while using less power on my RTX 5090.

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.
