+
+- **New Features**:
+  - Supports standard OpenAI API calls, which can be controlled through relevant parameters in the configuration file.
+  - Allows switching large language models during Chat API calls by passing the relevant configuration through the API call parameters.
+
+- **Updated Features**:
+  - Inference Module Initialization: Supports initialization of the inference module upon its first invocation, eliminating the need for full initialization at production line startup.
+  - Vector Library: Enables setting block size for long text and removes the control of interval duration between vector library calls.
