AI Agent / RAG / LLM Integration
AI Solution Development
Enterprise-grade AI solution development. From design to production for LLM integration, AI agents, and RAG systems — delivered by a team with hands-on AI-first experience.
Key features
AI agents & multi-agent systems
We design and build agents that execute tasks autonomously — production-grade systems with tool calling, workflow orchestration, and state management.
RAG (Retrieval-Augmented Generation)
RAG pipelines that retrieve from internal docs and knowledge bases to improve LLM accuracy — including vector DB selection, chunking strategy, and reranking.
LLM integration & fine-tuning
Model selection across OpenAI / Anthropic Claude / Google Gemini / open-source models, API integration, and fine-tuning where needed.
AI architecture consulting
We help with strategy for embedding AI into existing systems, cost optimization, and security/compliance design (APPI, GDPR).
Deliverables
- Requirements & architecture documents for the AI system
- Production-ready source code (GitHub repository)
- Deployed infrastructure (AWS / GCP / Cloudflare)
- API specification (OpenAPI)
- Operations manual & handover docs
- Unit & E2E test suites
Main tech stack
Engagement models
Project-based
We take on everything from requirements to delivery. Fixed price or milestone-based.
PoC / prototype
A proof of concept in 2–4 weeks to validate technical risk at low cost.
Advisory / consulting
Monthly architecture reviews, tech selection, and code reviews.
Pricing guide
We quote based on project size and complexity. A PoC starts around ¥500,000, and a full AI system from around ¥3,000,000.
* Final quotes are provided after an inquiry and a meeting.
Frequently asked questions
Q. Can you work with LLMs other than OpenAI?
A. Yes — Claude, Gemini, and local LLMs (Llama, Qwen, etc.). We propose the best model for your requirements, cost, and compliance.
Q. How is data handled?
A. For sensitive data, we can design everything to stay inside your cloud (within your VPC), with safeguards per Japan’s APPI.
