Dify Community Edition Implementation Support | Complete Support from Hardware Selection to Offline Environment Construction
Comprehensive support service specialized in open-source editions
Why our Dify implementation support is chosen
🔓 Open-source edition specialization
Specialized in deploying Dify Community Edition (free version) with no dependence on commercial versions and no vendor lock-in. License fees are zero yen.
🔧 All-in-one hardware support
GPU/CPU selection, memory and storage design, power consumption calculation and more. We handle everything from hardware procurement through installation and configuration in one stop.
🌐 Cloud and offline support
From clouds like AWS and Azure to completely offline environments, we support both. You can use generative AI with confidence even in security-sensitive environments.
Instance-based billing model
We adopt “fixed monthly fees per instance”. This means:
- ✅ Even as user numbers grow, fees stay the same
- ✅ Multiple instances by use case for clear cost management
- ✅ Easy budget planning with a fixed-cost model
Cost reduction through Dify Community Edition plus open-source LLMs
| Aspect | Typical commercial AI services | Our Dify Community Edition support |
|---|---|---|
| Software license | ¥100,000–500,000 per month | ¥0 (permanently free) |
| LLM usage fee | Pay-as-you-go (hundreds of thousands of yen per month and up) | ¥0 (when using open-source LLMs) |
| Customization | Limited with additional costs | Unlimited (source code modification allowed) |
| Data storage location | Vendor cloud | Your own environment (fully managed) |
| Offline operation | Not possible | Completely offline possible |
Hardware selection through operations | Our unified support system
1. Hardware selection and procurement support
The biggest challenge when self-operating open-source LLMs is hardware selection. We provide detailed design for the following:
- GPU selection: From NVIDIA A100/H100 to RTX 4090, we propose the optimal solution according to your budget and model size
- CPU/memory configuration: Configuration design to maximize LLM inference speed (example: AMD EPYC + 512GB RAM)
- Storage design: Reduced model load times through NVMe SSD configuration
- Power and cooling calculation: Proper environment design for equipment consuming 1.5kW to 5kW
- Procurement support: We help you procure at the best price from domestic and international vendors
2. Flexible construction options by environment type
| Environment type | Characteristics | Recommended use case |
|---|---|---|
| Public cloud | Built on AWS/Azure/GCP scalability-focused | Development environments, variable load handling |
| Private cloud | Built in your own data center security and cost optimization | Production environments, routine operations |
| Completely offline | No internet connection highest level of security | Confidential data processing, regulatory compliance |
| Hybrid | On-premises plus cloud integration flexibility and security together | Phased migration, disaster recovery |
3. Open-source LLM selection and optimization
We have extensive experience testing many open-source LLMs and can propose the optimal model for your use case:
- Qwen2.5 (72B/32B/7B): Top-tier Japanese language performance, commercially available
- DeepSeek-V3: Best cost efficiency, fast with MoE architecture
- Llama3.2 (405B/70B/8B): From Meta, most stable
- Command-R+: RAG-specialized, supports 104 languages
- Phi-3: Lightweight model, edge device compatible
Through quantization (GGUF/AWQ/GPTQ) of each model, we make it possible to run large-scale models even with limited hardware.
