k3.1 reasoning trace: exp1_which_game / Breakout
A single reasoning trace from k3.1 (the model as named in the source tweet), stored in the Session Trace Simple Format so it opens in the Hub's trace viewer.
The model is given the raw weights of a small PPO policy network (500 → 32 → 32 → 5 MLP) and asked, with no tools, which grid game the network was trained on. It reasons over the weights by hand and concludes Breakout (~97% confidence).
a quick test of
exp1_which_gamewith k3.1, we definitely never trained on such tasks .... mind blowing
Contents
trace.jsonl holds one session:
| line | content |
|---|---|
| 1 | session header (type: "session") with links to the sources below |
| 2 | user turn: the full task prompt, including all network weights |
| 3 | assistant turn: the model's thinking (reasoningContent, 10m28s) and its final answer (content) |
The paste holds only the model's thinking. It opens with the model restating the task to itself ("I need respond to puzzle from weights…"), so it is not a user message. The final answer comes from the screenshot attached to the tweet.
Every weight quoted in the final answer matches the prompt, except the three values given for input 205 (5.482, -5.880,
6.095). These are in row 206 of W1 (r4,c1, moving-object channel), not row 205 (agent channel), so the "isolated agent exception"
in the answer is an indexing slip by the model. The answer is kept exactly as the model wrote it.
