Qwen3-0.6B

'is' or 'was' after a subject

A neuron in layer 19 of Qwen3-0.6B. Its strongest snippets are fairly consistent: several of them peak on the same token. It is featured, so it has steering outputs.

What this neuron does

This neuron tends to fire on the verb that links a subject to what it is or was, like 'the same is valid' or 'the contest deadline is'. It switches off on words that start a new clause, such as 'that' after 'teaches us'. Turning it up did not produce any clear theme in the model's replies.

Written by Claude from this neuron's activations and steering outputs. Confidence: medium. Think it is wrong? Flag it (opens a prefilled issue on GitHub).
