unreleased​

release-2025-08-24​

  • Legacy NLU ist now configured as a billing product, not via a feature flag in the tenant.
  • Added support for OpenAI-compatible /v1/chat/completions endpoints. Removed vLLM, Fireworks.ai and Together.ai, as those now can be configured as such OpenAI-compatible endpoints.
  • All AI models provides with exception of Cohere and Ollama now are supported by the Agentic AI process module. This now enables complex agentic AI tool-calling and reasoning implementations with all kinds of LLM providers.

release-2025-08-23​

  • Added instructions to Agentic AI process module as a replacement for system message.
  • Process module ReachFive can now read, assure and create up to 3 consents in one request.
  • Performance optimizations in the widget for very long conversations.
  • Removed the setting that certain tenants might have AI capabilities disabled.

release-2025-08-22​

  • Refactored AI model select, which now shows pricing information and deployment region, such as European Union.
  • Added Scaleway gpt-oss-120b
  • Updated Anthropic models to newest versions.

release-2025-08-19​

  • The MCP server now requires the configuration of an Agentic AI process module in the agent. This module allows to configure the tools that should be made available via the MCP server. If no such Agentic AI module exists, the MCP endpoint will throw an HTTP status 400 error.
  • Added several model checking rules that ensure the correct configuration of the Agentic AI process module.

release-2025-08-18​

  • Process module AI Agent now represents tool configurations in an accordion with detailed configuration options for each tool.
  • The variables REST API is now disabled by default. It will throw an HTTP status 403 when called, and can be enabled in the tenant by LoyJoy support on request. This is due to security by default, as most tenants do not require this API.
  • Added LLM provider Mistral as another European model provider.

release-2025-08-12​

  • Enhanced messages screen for AI messages in the knowledge tab, including expandable cards for system messages for a more compact view, chat bubbles for user and assistant messages etc.
  • Web pages in knowledge sources now also like web sites can have settings for CSS selectors etc.
  • AI Agent process module
    • Now can configure tools.
    • In case OpenAI or Anthropic ist selected as the LLM model the tool web_search is available.
    • Added tool calling for Mistral and Anthropic additionally to OpenAI and Azure.
  • Process modules GPT gateway does not offer configuration of system and user message any more for stability reasons.
  • Added GPT-5 model family (GPT-5, GPT-5 Mini, GPT-5 Nano) for OpenAI
  • An empty list of sources screen now shows an empty message.
  • Fix for thumbs up/down at AI messages

release-2025-08-05​

  • In GPT Knowledge process module:
    • Removed text splitting for multiple topics in one user request, as this now can be addressed by agentic AI.
    • Removed reranking for performance reasons, as this optimization is not necessary anymore due to stronger AI models.
    • Raised the default number of chunks from 16 to 20.
  • AI knowledge messages screen
    • Tools list and tool call parameters are now visible in the AI messages screen.
    • In the RAG query now the query translations are visible, when multiple query languages have been selected in the GPT Knowledge process module.
  • Prepared the AI completions stack for web search capabilities like ChatGPT. This currently is only available with OpenAI, not with Azure.
  • Function knowledge: Allow specifying one folder to include in the chunk search. E.g. ${knowledge(user_answer, "FOLDER_NAME")}}.

release-2025-08-04​

  • Process module GPT Prompt now allows to include the chat history, so that the prompt can include the chat history into the analysis to produce an analysis result. This is preferable over printing ${chatHistory()} into the system message or user message, as ${chatHistory()} does not include the latest chat message of the customer, which triggered the processing of the GPT Prompt process module. Printing ${chatHistory()} into the system message or user message in the GPT Prompt process module should be avoided.
  • In process modules GPT Knowledge and GPT Smalltalk the prompt and system message have been unified into only the system message. The user message is now solely for the actual request of the customer.

release-2025-08-03​

  • Removed process module GPT Knowledge Follow-up, as the GPT knowledge module already covers follow-up questions, automatically.
  • Question rephrasing for the RAG pipeline in GPT knowledge is now executed with GPT-4o-Mini, if possible.

release-2025-08-02​

  • Optimized performance of knowledge messages list.

release-2025-08-01​

  • In the list of knowledge messages, added an error text in case an error has occurred in a GPT chat.
  • In process module GPT Knowledge:
    • RAG queries now are always rephrased to make sure that relative follow-up sentences always work with the RAG pipeline.
    • When checking the current Web page as part of the RAG pipeline, now a max size of tokens is ensured to prevent context window overflow.

release-2025-07-28​

  • In knowledge messages now all questions and answers of a conversation are shown in a unified view when clicking on AI communication in the top right corner. This allows to see all questions and answers in one place, which is useful for debugging and understanding the AI conversation flow.
  • The new Agentic AI process module allows to create agentic AI processes, which can be used to build complex AI workflows. Agentic AI processes are based on the Model Context Protocol (MCP) and allow to integrate external data sources, such as databases or APIs, into the AI process. The process module currently is in beta and will grow in the coming days and weeks with a growing set of MCP tools.

release-2025-07-16​
