I’m a solo indie developer from Japan, and I recently upgraded the local LLM powering my game **Hex Judge** from **Gemma 2 9B to Gemma 4 E4B**.

**Hex Judge** is a medieval witch trial investigation game where players interrogate villagers through AI-generated dialogue and uncover contradictions, relationships, and secrets.

One of the biggest improvements has been **conversation startup time**.

On an **RTX 2060**, starting an AI conversation went from around **45 seconds with Gemma 2 9B to less than 1 second with Gemma 4 E4B**.

We also experienced:

• Smoother NPC conversations

• Improved multilingual dialogue quality

• Faster AI interaction

The LLM runs **locally on the player’s PC**, without requiring an internet connection or an external AI API.

**Hex Judge currently supports 12 languages.**

This is my real-world experience using **Gemma 4 E4B as the local AI powering NPC conversations in a commercial game**.

I’m excited to see what Gemma 4 E4B can enable for local AI in games.

Hex Judge is available on Steam.
