+# Report Summaries with AI
+
+## Overview
+
+OpenCVE includes a feature that automatically generates **daily summaries of reports** using a Large Language Model (LLM).
+
+Each night at **2:00 AM UTC**, an Airflow DAG (`summarize_reports`) collects all the reports created the previous day and generates a concise summary for each of them by calling an LLM.
+
+This feature is especially useful for quickly identifying what really matters in the list of CVEs of the day, without having to manually read through each report in full.
+
+!!! info "Reminder"
+
+    A report is always linked to a project. It gathers all modifications concerning CVEs related to this project.
+
+    A CVE is related to a project when the project is subscribed to at least one of the CVE’s vendors or products.

+
+## Availability
+
+!!! info
+
+    On [OpenCVE.io](https://www.opencve.io), this feature is enabled for **Starter**, **Pro**, and **Enterprise** customers.
+
+If you are using the [on-premise version](https://github.com/opencve/opencve) of OpenCVE, you can also enable this feature, provided you have access to an API compatible with the **OpenAI API format** (Chat Completions endpoint).
+
+Compatible providers include:
+
+- OpenAI (ChatGPT models)
+- Anthropic (Claude models via OpenRouter)
+- Mistral (Mixtral, Mistral Small, etc.)
+- Llama.cpp (local inference with OpenAI-compatible API)
+- Ollama (self-hosted LLMs with OpenAI API compatibility)
+- Any other API exposing an OpenAI-compatible `/v1/chat/completions` endpoint
+
+## Configuration
+
+To enable report summarization on your own deployment, you need to configure the LLM endpoint in your Airflow scheduler.
+
+Edit the file `scheduler/airflow.cfg` and update the following section:
+
+````
+# The starting date of the summarize_reports workflow
+start_date_summarize_reports = 2025-08-28
+
+# The configuration for the LLM
+llm_api_key = sk-proj-1234567890
+llm_api_url = https://api.example.com
+llm_model = Mistral-7B-Instruct-v0.3
+````
+
+- `llm_api_key`: API key used for authentication (set to notused if not required by your provider).
+- `llm_api_url`: Base URL of your OpenAI-compatible API.
+- `llm_model`: Identifier of the model to use (provider-dependent).
+
+## Activating the DAG
+
+Once the configuration is in place, you need to activate the Airflow DAG named `summarize_reports`.
+
+You can do this from the Airflow UI:
+
+- Open the DAGs list.
+- Locate the DAG `summarize_reports`.
+- Switch it to active.
+
+From now on, every night at 2:00 AM UTC, the summaries of all reports created the previous day will be automatically generated.
