# Gemini 3.1 Flash Lite: cheap, quick, still not closed

- Description: Gemini 3.1 Flash Lite ran the full current suite quickly and cheaply. It reached five core passes, generated a valid City Plan SVG, and still resolved none of the nine practical paperwork cases strictly.

Gemini 3.1 Flash Lite is included as a cheap API comparison, not as a local model. It is useful because it shows what a very accessible current API model does on the same paperwork contracts as the Mac mini runs.

The short version is familiar: it understood enough to produce several near misses, but the exact job did not close. Proof codes, evidence paths, attachment indexes, normalized text, and payment reconciliation still broke the strict oracle.

## Where it worked

- Fast responses across the suite.
- Reached core-pass level on five of nine practical cases.
- Produced visible workflow artifacts in the agentic folder tasks.
- Generated a valid standalone City Plan SVG.

## Where it failed

- Zero strict resolved practical cases.
- Repeated proof-code and proof.txt failures.
- Evidence and attachment details did not match the hidden oracle.
- One workflow case missed core due normalized text, proof, and warning-code issues.
