π€ Simulation
Simulation β Test your voice agent against a realistic simulated user before shipping to production. Tuner automatically generates caller scenarios based on your agentβs configuration β no manual setup required. Each simulated call is evaluated against your configured evals and outcomes, so you can catch regressions, validate prompt changes, and stress-test edge cases without involving real users. Key Features:- Auto-generated scenarios β Tuner generates caller scenarios from your agent configuration and use case selections, so simulations are always grounded in your agentβs actual context
- Functional & pressure testing β Control the mix between functional tests that validate core use cases and adversarial pressure tests that probe failure modes and edge cases
- Targeted runs β Run simulations against a specific use case or a specific eval to isolate and validate exactly what youβre working on
- Automated evaluation β Each simulated call is scored against your existing evals, outcomes, and red flags

π Auto Sentiment Detection
Auto Sentiment Detection β Sentiment is now automatically detected and added as a default metric for every call β no configuration required. Tuner analyzes the conversation to surface caller sentiment signals, giving you an immediate read on call quality and user experience trends across your full call volume.March 23, 2026
π Enhanced Voice Metrics, Vapi Integration & Webhook Support
Enhanced Voice Metrics β The voice metrics dashboard now includes a detailed breakdown of latency by component β STT, TTS, and LLM β so you can pinpoint exactly where delays are introduced in your pipeline. Metrics are reported at the p50 and p90 percentiles, giving you a clearer picture of both typical performance and tail latency across your call volume. Vapi Integration β Connect your Vapi agents to Tuner with native platform support. Call data β transcripts, latency, evaluations, and cost β is captured and pushed to Tuner automatically for every Vapi-powered session. Learn more β Webhook Support for Retell & Vapi β You can now register additional webhooks in Tuner alongside your existing Retell and Vapi configuration. Tuner now forwards call payloads to your webhook URL after processing, so your existing automations keep running alongside Tuner without any changes.Learn more βMarch 19, 2026
π LiveKit & Pipecat SDKs, and Transcript Improvements
LiveKit SDK β Connect your LiveKit Agents to Tuner in two lines of code. Thetuner-livekit-sdk automatically captures session data β transcripts, usage, latency, and cost β and pushes it to Tuner when each session ends. No manual API calls required. Learn more β
Pipecat SDK β Monitor your Pipecat Flows pipelines with the new tuner-pipecat-sdk. The FlowsObserver captures flow transitions, latency signals, transcripts, and usage metadata, then sends a structured call payload to Tuner when the call ends. Learn more β
βοΈ Agents API β Create, retrieve, and update your agents programmatically via API. Learn more β
π Transcript Function Call View β Tool calls now appear inline in the transcript with their input arguments and output responses, making it easier to debug unexpected agent behavior.

π Metadata-Linked Evals & MCP Improvements
Metadata-Linked Evals β Evals can now reference call metadata, so they stay accurate even when agent instructions change per session or tenant. Attach any runtime context when pushing calls (instructions, tenant config, session properties) and each call is evaluated against its own context, not a shared static policy. Learn more β Tuner MCP Improvements β Enhanced the MCP prompt with deeper understanding of your agentβs context. It now suggests more comprehensive configuration across outcomes, intents, evals, red flags, and data extraction, plus ships with richer built-in templates so your initial setup is closer to production-ready out of the box.February 25, 2026
