OpenSlice 2025Q4 Release

OpenSlice is an open source, service-based Operations Support System (OSS) prototype for delivering Network Slice as a Service (NSaaS) and more widely, Network as a Service (NaaS) following specifications from main Standards Development Organizations (SDOs), including ETSI, TM Forum, GSMA, and 3GPP.

 

In January 2026, the ETSI Software Development Group OpenSlice (SDG OSL) announced the 2025Q4 release of OpenSlice!

 

This latest release represents one of the most advanced development cycles of the platform to date, introducing a strong shift toward AI-native operations. Key enhancements include the integration of Agentic Orchestration, local LLM deployments, a new AI Assistant, and advanced Telco Cloud controllers, further strengthening OpenSlice’s capabilities in automated and intelligent network management.

 

With AI now moving from experimentation to operational deployment, the platform enables more autonomous, flexible, and secure orchestration workflows. At the same time, the release continues to reinforce OpenSlice’s core mission by expanding cloud-native capabilities, improving interoperability, and bridging OSS and BSS layers to support real-world telecom service delivery and commercialization.

 

These updates further establish OpenSlice as a cutting-edge open-source solution supporting the evolution toward Autonomous Networks and next-generation telecom ecosystems.

 

As a contributor to the OpenSlice ecosystem, K3Y Ltd actively supports the evolution of open, standards-based solutions for next-generation network orchestration.

 

What’s New in OpenSlice 2025Q4

 

AI-Native

 

Beyond the OpenSlice MCP Server updates, the new MCP Backend enables tool-calling via local LLMs, providing a private and secure foundation for the OpenSlice AI Assistant.

 

Agentic Orchestration

 

Orchestration enters a new era with the ability to invoke multiple autonomous agents during a service’s lifecycle, enabling multi-agent patterns that bridge the gap between intent and execution.

 

Telco Cloud Enhancements

 

New controllers now support GitOps-driven infrastructure management and native integration with Nokia’s NaC platform.

 

BSS & Product Management

 

A new prototype TMF Product UI allows for better visualization and management of the product layer, tightly coupled with the underlying OSS stack.

 

Ready-to-Deploy Blueprints

 

A dedicated repository of artifacts allows users to import and deploy complex services, such as a 5G Core, within minutes of setup.
