That’s pretty impressive. I wonder how they handled biter attacks and some of the real-time requirements.

Getting good coding results with Astra Ultra agent and Astra Low subagents.

As far as I understand, the best any AI was able to get to until now was being able to produce blue science which is like level 2 or 3 of a science tree like 10 levels deep. To me who has maybe put 20-30 hours into Factorio, this is even more impressive stuff than some of the Blender videos I've seen... just mind-boggling.

Let’s see the factory layouts though. Release the blueprints!

The factory must grow, and now it can grow while you sleep, which is the one thing Factorio players never managed.

Can someone ELI5 how LLMs are manipulating environments like this? I have a similar question for when you see the blender examples online. AFAIU the models are multimodal, so you could screenshot factorio and let it come back with some manipulation like move west 5 tiles, do that and then take another screenshot, but that seems wildly inefficient so I'm sure i'm missing something

How is the AI controlling the video game? Is there special coding/harness that allows for this?

Lots of people in here asking how it was done. Heres what the linked page says: >...made a mode in LUA for the game to expose an MCP server that allows the llm to play the game. (Factorio has a very mature LUA based modding system )
