I can't get it to call any of my tools, including the built in ones? The docs only state that the knowledge base doesn't work—so I expected tools to work.

Yes, OpenAI realtime technically supports tool calling, but there are known issues with it, especially with the

gpt-4o-realtime-preview

model. According to multiple sources, users have reported that "Tool calls are not working with Open AI Realtime model" and "when switching to the models gpt-4o-realtime-preview the webhook is calling but the answer is not parsed well" ([Discord discussion](https://discord.com/channels/1211482211119796234/1336440478727667844)). Suggested workaround: Use the standard GPT-4o model instead of the realtime version for more stable tool calling functionality.

You can call tools, but information retreival from the tool doesn't work.
