Feature #1935

Fires on “list” (not labeled yet: read the examples)

Fires on
1.47% of tokens
Mostly in
agent
Layer
after block 4

Where it fires

  • agent 54%
  • python 33%
  • worksheet 6%
  • story 5%
  • chat 1%

Makes the model say

<|arg|>]<|tool_call_end|><|assistant_end|>()<|tool_end|> about

Makes it not say

range[::-Once counts [ upper returns Python

Strongest examples

On text the dictionary never trained on. The underlined token is where it fires most.
