DEMO / RECORDING
From the original post
Jev + Astra beats the Ender Dragon in Minecraft in 8 minutes 43 seconds! ⏱️
Cost less than $1 ($0.01 Jev, $0.96 Astra)
I open sourced the code and explain the harness setup below. This type of movement is only possible with Jev's near instant decisionmaking, and some continually learning skills from Astra.
How Jev fits in the loop
- Agent collects runtime context or input state from external sources.
- Bounded decision options are formatted into Jev System One questions.
- Jev scores each candidate option and returns a probability for it.
- Deterministic code executes the selected action or routes to specialized models.
How to reproduce
- Read the author's original post on X at https://x.com/rronak_/status/2101544156757950697.
- Inspect the described workflow architecture and bounded decision points.
- Test Jev System One decision queries against the provided task context.
