• Compare A/B test results across different agents.

You can now export and import any agent to your different organizations.

Export Call History Data

Export the complete call history using the selected filters and column settings, mirroring the call history table.

Bug fixes and improvements

1. New Voices for OpenAI Realtime: openai-Ash, openai-Coral, openai-Sage

2. LLM and TTS Fallback for individual calls

• Now if the provider is up, but two consecutive failed utterance will trigger a fallback within individual calls.‍

‍3. LLM deprecation & upgrade:

• claude 3 haiku will be deprecated, and all agents using that will be upgraded to claude 3.5 haiku;
• claude 3.5 sonnet will soon be upgraded to claude 3.7 sonnet
