ServiceNow is ending the default use of its in-house large language model, Now LLM, and shifting towards integrating advanced third-party models like Google Gemini and OpenAI GPT. This update shows ServiceNow's strategy to provide more powerful, flexible, and cutting-edge AI capabilities for its users. well I think that it's for the greater good lol.

 

 

Key Updates:

New Third-Party Models

• Google Gemini 3.5 Flash  replaces the earlier Gemini 2.5 Flash.
• OpenAI GPT 5.1  and  OpenAI GPT 5.4 Mini  are added to the platform.

These models now form the core of ServiceNow’s generative AI offerings, providing users with improved performance, larger knowledge bases, and enhanced contextual understanding.

Now LLM Is No Longer the Default Model

The July update marked a significant shift the Now LLM is no longer the default model for any AI skills or agents on the platform. This means existing users must:

• Update their  AI configurations
• Choose from available third-party LLMs as their new default
• basically, change all thing that previously were consuming Now LLM

Retirement of Now LLM Long-Term Support (LTS) SKU

As of June 2026, the Now LLM LTS SKU has been retired, signaling an end to long-term support for the in-house model. Customers currently using this SKU will need to migrate to third-party models to ensure continued support and compatibility.
