LLM Admin - Open-source and free localized LLM unified API, saving money and worry

What is LLM Admin

LLM Admin is an open-source and free localized LLM unified gateway, licensed under Apache-2.0. Through one set of APIs compatible with the OpenAI and Anthropic protocols, it easily orchestrates 80+ mainstream models and supports multimodal intelligent routing for text, images, and more. The platform features built-in declarative custom routing, multi-Key automatic load balancing and failover, and, combined with Prompt caching, intelligently routes requests to low-cost models, significantly reducing Token expenses. The intuitive desktop management interface makes configuration adjustments and usage monitoring clear at a glance, with data processed entirely locally and zero privacy leakage.

Main features of LLM Admin

• Unified interface: One set of APIs to call 80+ mainstream models, with text generation and image generation capabilities at your fingertips.
• Protocol compatibility: Compatible with both OpenAI /v1/chat/completions and Anthropic /v1/messages protocols, with no need to modify client code.
• Custom routing: Declarative routing rules, supporting failover, load balancing, and primary-backup strategies.
• Intelligent routing: Automatically assigns the best model by modality such as text, image, video, and audio.
• Multi-Key support: Multiple API Keys can be configured for the same provider, with automatic distribution and disaster recovery, avoiding single points of failure.
• Usage statistics: Built-in dashboard monitors Token consumption and costs in real time, making every expense clearly visible.
• Plugin system: Supports extensions such as Prompt caching and Guardrails, enhancing functionality as needed.
• Local deployment: Data is processed entirely locally and never leaves the local environment, ensuring privacy security and compliance.
• Open-source and free: Apache-2.0 license, freely downloadable, customizable, and available for secondary development.

• Connect providers: Add your API Key in the desktop management interface, supporting mainstream vendors such as OpenAI, Anthropic, DeepSeek, Zhipu, Doubao, and Moonshot AI.
• Add models: Select the corresponding model from the connected providers, such as glm5.2, to complete model integration.
• Specify routing: Configure declarative routing rules, such as primary-backup strategies and load balancing strategies, to achieve automatic failover and request distribution.
• Start using: After routing configuration is complete, clients can call 80+ models through the unified interface, with no need to modify code or switch platforms.

Core advantages of LLM Admin

• Save money: Prompt caching combined with load balancing strategies intelligently routes requests to low-cost models, saying goodbye to single-provider lock-in and runaway expenses.
• Worry-free: The desktop management interface lets you modify configurations, adjust routing strategies, and view usage with what you see is what you get, saying goodbye to manually editing JSON and command-line restarts.
• Reliable: Automatic load balancing for any upstream failure, so single-point jitter does not affect business continuity.
• Powerful: High-performance architecture supports high concurrency and stably supports critical business scenarios.

LLM Admin Use Cases

• Application development with mixed multi-model use: Flexibly switch between multiple providers such as OpenAI, Anthropic, DeepSeek, and Zhipu without rewriting client code, accessing 80+ models through one interface.
• Writing and Content Creation: Tasks such as daily polishing and expansion are routed by default to low-cost domestic or small models, automatically switching to top-tier models only at key draft stages, significantly reducing content production costs.
• AI Agents and Automation Tools: Provides a unified backend proxy for agents, AI assistants, and OpenClaw-like automation tools, shielding interface differences across providers and ensuring stable, available service.
