# What's New: Week of June 29, 2026

1. **OpenAI Realtime v2**: OpenAI's latest [Realtime v2](https://docs.vapi.ai/openai-realtime) model is now available for assistants.

2. **AI-Generated Tool Failure and Completion Messages**: You can now set `role: 'system'` on request-failed [tool messages](https://docs.vapi.ai/tools/custom-tools), and the dashboard has a new UI for configuring AI-generated messages when tools fail or complete. This gives assistants more natural responses when tools hit errors.

3. **Call Logs Improvements**:
   * Significant latency improvements across both the dashboard and the `/calls` API endpoints.
   * The call detail flyout now shows which assistant or squad handled the call, includes a link to the assistant or squad, and indicates which phone number was used.
   * In squad or handoff calls, transcript messages now show which assistant said what, making it easier to trace conversation flow.

4. **MCP Child Tools in Dashboard**: When you connect an [MCP server](https://docs.vapi.ai/sdk/mcp-server), the dashboard tool form now lists all child tools it discovers, so you can see exactly what capabilities your MCP server exposes.
