**RAPTOR** is an enterprise AI runtime for building agentic applications over video, audio, images, documents, and organizational knowledge — providing MCP tools, A2A orchestration, persistent memory, hybrid RAG, GraphRAG, evaluation, guardrails, and model lifecycle services. Developed by the **DHT Taiwan Team** at [DHT Solutions](https://dhtsolution.com/).
## 🚀 Current Release
**Aigle 0.4** - Community Beta (August 2026)
This release continues the open-source RAPTOR framework, codenamed "Aigle". Release 0.4 grows the platform to **27 independently deployable Docker Compose modules** (three earlier modules — hybrid-search, graph-database, graph-service — are retired and kept only for rollback) driven by the same single build system (`Aigle/0.4/deployment/modules/build.py`), and delivers the v0.4 roadmap: MCP interfaces across core services, persistent multimodal memory, and a per-user isolated multi-model database that replaces the previous Qdrant/OpenSearch/Neo4j trio.
**Highlights:**
- 🔌 **MCP Server** — Raptor's search, RAG, asset, and memory APIs exposed as Model Context Protocol tools/resources for LLM clients (module 27)
- 🧠 **Memory Service** — persistent per-user/per-session memory (facts, preferences, conversation history, multimedia) backed by MemVID, layered underneath the existing Redis short-term chat cache (module 26)
- 🗄️ **Personal DB Service** — one physically isolated ArcadeDB database per user, replacing the old per-user Qdrant + OpenSearch + Neo4j trio with unified hybrid BM25 + vector + graph + temporal-fact search (modules 24/25)
- 🛡️ **Guardrail Service** — LLM input/output content moderation with pluggable guard models (Llama Guard 3 / Granite Guardian / GPT-OSS-Safeguard) and a policy engine; ships disabled by default (module 23)
- 📊 **Benchmark Service** — user-defined scoring schemas (keyword match, LLM-as-judge, cosine similarity) to regression-test chat/RAG/search/classification pipelines (module 22)
- 🎬 **Video Search 2.0, GraphRAG, A2A, branch isolation** — carried over from Aigle 0.3 (see [Features](#-features) below)
See [`Aigle/0.4/README.md`](Aigle/0.4/README.md) for the module reference, [`Aigle/0.4/BUILD.md`](Aigle/0.4/BUILD.md) for the build guide, [`Aigle/0.4/API_REFERENCE.md`](Aigle/0.4/API_REFERENCE.md) for the API reference, and [`Aigle/0.4/MCP_REFERENCE.md`](Aigle/0.4/MCP_REFERENCE.md) for the new MCP reference.
### 🧪 Evaluation and Testing API (Aigle 0.4)
To help developers get started with the RAPTOR framework quickly and easily, we've deployed a **test run API** on DHT's development infrastructure. This evaluation API allows developers to:
- **Test and evaluate** RAPTOR capabilities without setting up infrastructure
- **Develop AI applications** using the RAPTOR framework with zero deployment overhead
- **Utilize DHT resources** for testing and development purposes
- **Prototype faster** by accessing pre-configured AI services
This is an excellent way to explore RAPTOR's features, build proof-of-concepts, and validate your use cases before deploying your own infrastructure.
**🔗 Access the Evaluation API:**
[http://raptor_open_0_4_api.dhtsolution.com:8012/](http://raptor_open_0_4_api.dhtsolution.com:8012/)

## 🎯 About RAPTOR
**RAPTOR** is an open-source **multimodal AI framework and agent harness** — an enterprise AI runtime for building agentic applications over video, audio, images, documents, and organizational knowledge. Rather than a single content-search product, RAPTOR is a platform of composable services that an agent (or a human developer) can call directly: MCP tools and A2A orchestration for agent interoperability, persistent multimodal memory, hybrid BM25/vector RAG, GraphRAG and temporal knowledge graphs, pipeline evaluation and benchmarking, LLM guardrails, and model lifecycle management — all exposed as REST, MCP, and A2A interfaces over the same per-user isolated index.
### Business Value Proposition
- **85% reduction** in manual content tagging and metadata generation
- **10x faster** content discovery through semantic search
- **60% improvement** in content reuse and operational efficiency
- **Real-time insights** from video, audio, and document content
- **Agent-ready by default** — every capability above is callable by an LLM agent (MCP), another agent framework (A2A), or a human developer (REST), not locked behind a single interface
### Strategic Differentiators
1. **Agent-Native Interfaces**: MCP tools and A2A orchestration (agent cards, JSON-RPC, five spec-compliant sub-agents) expose the platform to LLM agents and other agent frameworks, not just human API callers
2. **AI-Native Architecture**: Built from the ground up around LLM orchestration and vector search
3. **Multi-Modal Understanding**: Unified analysis across video, audio, image, and text
4. **Semantic Intelligence**: Hybrid BM25 + vector search plus GraphRAG and temporal knowledge graphs for context-aware retrieval, not just keyword matching
5. **Composable Enterprise Services**: Persistent memory, LLM guardrails, pipeline benchmarking, and model lifecycle management as first-class, independently deployable services
6. **Open + Enterprise Model**: Open-source core with premium enterprise features; Docker Compose today, with a Kubernetes-native production path planned for v1.0
## ✨ Features
### Version Aigle 0.4
New in this release:
- **MCP Interfaces**: Model Context Protocol tools/resources over search, RAG, asset, and memory APIs, plus MCP Prompts (module 27)
- **Memory Service**: persistent per-user/per-session facts, preferences, conversation history, and multimedia memory on MemVID, with hybrid semantic + BM25 retrieval, layered under the existing Redis short-term chat cache (module 26)
- **Personal DB Service**: one physically isolated ArcadeDB database per user — unified vector, BM25, and graph storage replacing the old per-user Qdrant + OpenSearch + Neo4j trio (modules 24/25)
- **Guardrail Service**: LLM input/output safety checks (Llama Guard 3 / Granite Guardian / GPT-OSS-Safeguard) with a policy engine and violation audit logging; ships disabled by default (module 23)

```bash
# Clone the repository
git clone https://github.com/DHT-AI-Studio/RAPTOR.git
cd RAPTOR/Aigle/0.4
# Configure: copy the templates and fill in hosts, credentials, and model names
cd deployment/modules
cp .env.example .env
for m in */; do [ -f "$m/.env.example" ] && cp "$m/.env.example" "$m/.env"; done
cd ../..
```
See [`Aigle/0.4/BUILD.md`](Aigle/0.4/BUILD.md) for the full configuration reference.
## Development
```bash
cd Aigle/0.4
# Build the shared GPU base image first (used by modules 09-12)
bash deploy.sh -m 08 --build
# Start all modules in dependency order (or --cpu-only to skip GPU modules)
bash deploy.sh
# Inspect
bash deploy.sh --status # running / stopped status per module
bash deploy.sh -m <id> --logs # follow a module's logs
```
## Quick Start
1. Deploy the platform (see [Development](#development) above), then open the API Gateway docs:
```bash
curl -s http://<host_ip>:8012/docs
```
2. Log in through SSO to obtain a token (users/groups are managed by the authentication module, Keycloak-backed):
```bash
curl -X POST "http://<host_ip>:8012/api/0.4/sso/login" \
-H "Content-Type: application/json" \
-d '{"username": "<user>", "password": "<password>"}'
```
3. Upload a media file for automatic AI processing (transcription, OCR, frame description, summary, embeddings, knowledge graph):
```bash
curl -X POST "http://<host_ip>:8012/api/0.4/asset/fileupload_analysis" \
-H "Authorization: Bearer <token>" \
-F "file=@/path/to/video.mp4"
```
4. Search — video-centric, multi-recall (BM25 + Vector + GraphRAG + TKG) with cross-encoder re-ranking:
```bash
curl -X POST "http://<host_ip>:8012/api/0.4/search/video_search" \
-H "Authorization: Bearer <token>" \
-H "Content-Type: application/json" \
-d '{"query": "OpenAI announcement", "top_k": 5}'
```
5. Ask questions over your content with RAG chat:
```bash
curl -X POST "http://<host_ip>:8012/api/0.4/chat/chat" \
-H "Authorization: Bearer <token>" \
-H "Content-Type: application/json" \
-d '{"message": "Summarize the uploaded video"}'
```
Or use the **demo frontend** instead of raw APIs:
```bash
cd Aigle/0.4/raptor-demo-frontend
cp .env.example .env # set API_TARGET / DEMO_PORT
docker compose up -d --build
```
