Much better than it was before but it’s still significantly weaker than a direct chat.

For example I asked

“Why should LLM attention use dot product instead of cosine similarity, being that we often hear vector magnitude does not encode most of the useful information needed”?

The voice response was directionally right but lacked detail and was a little hand wavy.

The answer to the same question in a text chat was much higher quality.

The voice response replied “let me think about that…” so it appears to be invoking 5.5 as advertised, but it’s definitely weaker.

I had reasoning set the same for both.

A lot of this is steerable! Our current personality is optimized for brainstorming and conversations, but you can provide custom instructions to ask it to go deep and give you info-dense or more technical answers.

I would naturally assume they cut the background thinking level to the minimum. It's a halting problem question and with in text 5.5 with max thinking will chew on a question for 5-10 minutes sometimes. That would make a pretty awkward conversation.
