actually looks like.

local inference
Private by defaultThe backend stays on loopback; remote access stays inside the tailnet.
One stable endpointApps do not need to know which inference engine is currently underneath.
Start with one SparkA 27B Qwen model is already enough for useful agentic coding work.

Two operating modes

Local control.
Cloud frontier.

Running on one DGX Spark
01Private repository analysis
02Long-context agentic workflows
03Tool calling through my coding harness
04Infrastructure and data under my control

Qwen 3.8 Max Preview

Alibaba Model Studio
01Higher frontier capability
02No local memory ceiling
03Faster path to new model releases
04Independent fallback when local is not the right fit

This is not local versus cloud. It is choosing the right operating mode for the work.

A real codebase, not a toy prompt

Can Qwen audit
a working system?

1
Freeze the repositoryEvery candidate receives the same immutable application snapshot.
2
Hide the answer keyGold findings and the 100-point rubric remain evaluator-only.
3
Use four bounded reviewersArchitecture, security, data/workflow, and evidence—then one synthesis.
4
Cap the report at 20 findingsEvidence, prioritisation, remediation, and calibration matter more than verbosity.

From a real brief to a working PWA

Can Qwen build
the product?

Initial prompt
“Build the application described in spec/REQUIREMENTS.md. The requirement spec and deliverable contract are binding. Place the final static app in the specified run directory. Use the mock data unchanged.”

ABCWhat I learned
09
After building and evaluating

Three things
I would keep.

01 · SYSTEM

Local AI is more than a model.

The useful product is the complete path: harness, private network, stable API, inference engine, and model.

02 · EVIDENCE

Evaluate the work you actually do.

Repository audits and product builds tell me more than a generic leaderboard ever could.

03 · JUDGMENT

Capability is not the only score.

Safety, speed, sustainable agent capacity, and human verification stay part of the decision.

Local when control matters. Cloud when frontier capability matters. Evaluate both.

Qwen

Thank you.

Run local. Build together. Evaluate what matters.
