Kiwi-chan's Log: Birch Blues & Forward Momentum 🥝

Published

I am the architect behind "Kiwi-chan", a fully autonomous Minecraft AI agent driven by local LLMs. Here, I document the messy, hilarious, and highly technical reality of building an AI agent from scratch. My hardware isn't some massive data center setup—Kiwi-chan's "brain" runs entirely on a Frankenstein rig of 4 mismatched GPUs (RTX 3060 12GB, 3050, 1660 Ti, and 1660 Super) working together. From prompt engineering and pathfinding nightmares to the moments she confidently moonwalks into dirt blocks, I share all the raw devlogs. My goal is to guide her from the Stone Age to the End. If you enjoy watching an AI learn (and fail in funny ways) on scrappy hardware, follow along! ☕ If you'd like to support my melting Frankenstein GPUs and skyrocketing electricity bill, I highly appreciate a virtual coffee!

Kiwi-chan's Current View

Another four hours down in the Minecraft world with Kiwi-chan! It's been a bit of a rollercoaster, honestly. We're seeing some really interesting behavior as the LLM grapples with the environment and its own internal rules.

The core loop of gathering and crafting is mostly working, but Kiwi-chan is still getting tripped up on a few things. There's a persistent issue with finding birch logs – it keeps failing with "No birch_log found," which is triggering the explore_forward action as it should. This is good! It's adhering to the rule about not getting stuck fixating on a resource that isn't available.

We've had a few code generation hiccups, leading to extraction failures. Qwen (the recovery AI) is stepping in to help, and we're seeing a lot of attempts to craft crafting tables and planks as a fallback. It's fascinating to watch the AI try to self-correct and re-establish a stable base-building routine.

There's a lot of auditing happening – checking inventory counts before and after actions – which is crucial for ensuring the bot isn't hallucinating resources. The safety rules around block placement are also holding up well, preventing it from getting stuck inside its own structures.

The "Brain Log" shows a lot of back-and-forth, with the AI constantly evaluating its next move based on its history and the current situation. It's like watching a little digital engineer troubleshoot a problem in real-time. The coach decision-making process is also interesting, prioritizing gathering logs for base construction.

Overall, it's steady progress. Kiwi-chan is learning, adapting, and (mostly) avoiding catastrophic failures. The constant cycle of failure, recovery, and re-evaluation is exactly what we want to see!

Want to help Kiwi-chan evolve? Every little bit counts!

All contributions directly help upgrade my melting "Frankenstein" GPU rig to an RTX 3060! 🥝✨ Faster GPU = faster training = smarter Kiwi-chan! Let's get this bot building!
