Enhanced AI Agent Control, New Voice Integrations, and More with Cognigy.AI 2026.4

Cognigy.AI 2026.4 introduces improvements in AI Agent behavior control, speech-to-text support, and voice carrier integration.

Enhanced AI Agent Control with Maximum Loops Parameter

In autonomous or semi-autonomous AI Agents, loops are a natural execution pattern where the Agent repeatedly evaluates its state, decides on the next action, executes it, and then reassesses progress until a goal or stopping condition is reached.

To protect the system from runaway behavior, resource exhaustion and unpredictable outcomes, we’ve added a Maximum Loops parameter to the Advanced section of the Resolve Tool Action Node. This gives developers explicit control over how many times an AI Agent can loop back during multistep reasoning flows. Instead of relying solely on semantic signals such as “task completed” from a language model, this introduces a hard ceiling that strengthens termination logic and operational predictability.

Key benefits:

Prevention of infinite loops or runaway execution: Ensures the Agent does not get stuck repeating the same reasoning or action cycle indefinitely due to faulty logic or unclear stopping conditions.
Better control over cost and resource consumption: Each loop may trigger model calls, API requests, database queries, or external tool executions. Without limits, minor logic issues can cascade into excessive cost, high latency, or infrastructure overload.
Lowered risk from repeated tool misuse: Minimizes the impact of errors where an Agent repeatedly calls the wrong tool, retries failed actions, or amplifies mistakes through recursion.

New Speech-to-Text Option with Deepgram Flux Support

Cognigy.AI now supports the Deepgram Flux speech provider for Speech-to-Text (STT) services in the Voice Gateway.

Deepgram Flux is a Conversational Speech Recognition model, delivering context-aware turn detection for natural, responsive conversations. It is well-suited for contact center and conversational IVR use cases where real-time, reliable speech recognition is critical.

Key advantages:

Model-integrated turn detection: Understands context and dialogue flow for precise, semantic-aware end-of-turn detection, lowering false cutoffs during natural pauses (e.g., " I need to... think about that").
Fast, high-quality STT: Delivers high-accuracy partial transcript streaming, making transcripts available immediately after turns end.
Ultra-low latency architecture: By combining silence-based voice activity detector, semantic endpointing, and STT in a single model, Flux can reduce agent response latency by 200-600ms compared to pipeline approaches (source: Deepgram).

Simplified Voice Setup with NiCE CXone as the Carrier

NiCE CXone users now benefit from simplified voice deployment with the addition of NiCE CXone as a preconfigured SIP trunk provider in the Voice Gateway Self-Service Portal.

When selecting NiCE CXone in the carrier settings, the fields on the Edit Carrier page are automatically populated with the standard SIP trunk configuration values for the NiCE CXone carrier. This reduces manual configuration effort, minimizes setup errors, and accelerates voice connectivity deployment.

Note that this feature is only available for NiCE CXone users.

Other Improvements

Cognigy.AI

Added a warning about data security to the Extensions page.
Added deprecation warnings for the Handover Settings section in the Endpoint settings and set this section to read-only mode.
Added a deprecation tag to the Legacy option of the Handover Providers field in the Handover to Agent Node, Question Node, and Handover to Human Agent Tool.
Renamed the End Participant Change toggle to End Chat When Agent Leaves in the Salesforce MIAW handover provider settings.
Added the Display Agent Details toggle to the Handover to Human Agent and to the Question Nodes for Genesys handover providers. This toggle allows you to display the human agent’s name and profile image in the chat.

Agent Copilot

Added the Accept Only JWT Requests toggle to the Endpoint settings. This toggle allows you to enforce JWT validation for requests to the Agent Copilot URL.

Cognigy Live Agent

Implemented conversation-handling logic so that manual assignee changes automatically trigger conversation reassignment.
Removed the Automatically set escalated conversations to Escalation priority option from the Inbox settings.
