# 2025.24
In Cognigy.AI 2025.25.0, transformers will start using the `axios` library for handling HTTP requests internally instead of `request-promise`. For more details, read [Transformers Overview](/ai/for-developers/transformers/overview).
The following Anthropic models have been removed from Cognigy.AI because they are no longer supported by Anthropic: `claude-3-5-sonnet-20241022`, `claude-3-5-sonnet-latest`, `claude-instant-v1`, and `claude-v1-100k`.
If you use these models in your Flows, replace them with available models from the [Model Support by Feature](/ai/agents/develop/gen-ai-and-llms/model-support-by-feature) list to ensure your AI Agents remain stable.

The Simulator is an LLM-powered tool in Cognigy.AI that allows users to model and test full conversational scenarios for LLM-based AI Agents. Use the Simulator to mimic real-world user interactions and evaluate the performance, behavior, and reliability of AI Agents in controlled environments. You can try the Simulator in the [trial environment](https://trial.cognigy.ai/).
##### New Handover Provider for storm from Content Guru

With the storm handover connector, you can integrate Cognigy.AI with storm, enabling end users to connect with human agents working in a contact center that uses storm.
