[Madrigal]

This is something that is actively being looked at. No ETA yet

[lucix-aws]

This is prioritized and @Madrigal is actively working on it. We originally had to hold the release of this because the operation doesn't work with the way our event stream APIs are exposed.

[ajrice6713]

Also interested in this functionality - any ETA would be greatly appreciated!

[mcastilho]

We have been waiting for this also. We have implemented all of our Nova Sonic tool calling and transcript handling in golang but we use a temporary NodeJS Proxy to stream Sonic events back to "golang".... With this method InvokeModelWithBidirectionalStream we can finally implement all of Nova Sonic directly in Golang. @Madrigal @lucix-aws

[arkadijs]

Hi, any updates on this?

[jbarnard-et]

is this still being worked on?
