Developer builds local Gemma 4 community moderation tool; disabling thinking keeps quality
salary_pending · reddit · 2026-11-15
A developer running several small communities built a moderation script on top of an existing content-tracking app: each item pending review is checked against stored community-rule notes by a locally running Gemma 4, which decides whether it violates the rules; flagged content is automatically removed with a stated reason.
Lessons learned:
- GPT-OSS-20B was fast but produced poor moderation results;
- Gemma 4 with thinking enabled worked well but was extremely slow;
- Disabling thinking gave a big speed boost with no noticeable quality drop.
The author plans to test at scale and may ship the tool to friends, noting that local setup is nontrivial and wider use would require hosting the model.
