Private AI, Unlimited Usage
There are lots of ways to manage AI costs and serve models. There are also plenty of different kinds of software promising to help. You've probably tried some. Yet, here you are.
Unfortunately, most of these solutions are either technical, expensive, or lacking in features and production readiness.
Not Courier. Courier is refreshingly simple and affordable with plug-and-play production readiness. It's no-nonsense, efficient, and reliable.
So, we invite you to poke around, check out some information below, and try Courier for free. We'd be honored to have you as a customer.

AI Token Spend Increased 49.7% in 2025
As AI adoption grows so do token costs. Companies are increasing their budgets every year to account for their AI usage costs and privacy concerns.
No Data Control
Your sensitive data flows through third-party servers. You have no control over security or compliance.
Unpredictable Costs
Per-token pricing eats your margins as you grow.
Vendor Lock-In
Closed models and proprietary APIs trap your business.
We Prefer Self-Hosting
With tech innovations by Apple and advancements in open source AI you can now self-host your intelligence layer affordably and reliably.
Renting
When you pay for cloud solutions you are paying for 3 things:
- GPUs - Companies like OpenAI, Anthropic and Gemini build server farms filled with GPUs for hosting AI models
- AI Models - These companies build and train cutting-edge AI models
- APIs - They provide software that hosts these models on GPUs and allows you to communicate with them
Ownership
To own your AI stack, you need those same 3 things. To do this, we use:
- Apple's Unified Memory. It's less than 1/10th the cost of traditional NVIDIA GPUs.
- Open source LLMs by companies like Mistral and Qwen. These models are outperforming mainstream models and completely free to use in commercial applications
- Courier - We've built software that turns any M-series mac into an AI API platform with plug and play ease.
We chose Apple's Unified Memory Architecture because of how affordable and performant it is. Our software is optimized for their memory architecture and handles all the complexity of running open source AI models. You can use models running on our cloud completely free with rate limits or purchase your own Mac and subscribe for a flat-rate.
Enterprise Features That Make Self-Hosting simple, affordable, and reliable.
Available to Anyone
Courier provides premium capabilities that go far beyond simple model serving, turning affordable Apple hardware into production-ready AI API platforms with plug-and-play ease.
Optimized For Speed
Our platform is optimized for maximum throughput on Apple Silicon, averaging 30-60 tokens/sec.
Learn more →Industry-Leading Tool Calling
Industry-leading tool calling for self-hosted AI stacks, with production-ready reliability for text-based models. One of the most robust OpenAI-compatible tool-calling implementations available on an API platform you can own.
Learn more →Automatic Hallucination Detection
Our system detects when models hang or hallucinate and automatically restarts them. You only lose one request instead of an entire queue, ensuring maximum uptime and reliability even with SLMs.
Learn more →Intelligent Memory Management
When new models need memory, our LRU policy automatically offloads least recently used flex models. This ensures optimal memory utilization without manual intervention, crucial for production workloads.
Learn more →Flexible API Deployment
Deploy models as 24/7 static APIs or on-demand flex APIs. Flex models auto-offload after 5 minutes of inactivity, optimizing memory usage while maintaining low latency for active workloads.
Learn more →High-Availability Round Robin
Load multiple model instances to create a round-robin API. This approach provides automatic failover and batching on Apple's Unified Memory Architecture. If an instance hallucinates, the other instances pick up the slack, resulting in better uptime, reliability and throughput with smaller models.
Learn more →Whisper API Support
Production-ready OpenAI-compatible transcriptions and translations with multiple output formats, timestamp controls, and predictable error behavior for automation workflows.
Learn more →Comprehensive Analytics
Our platform includes robust analytics so you can track usage, tokens, response times, and more from your analytics dashboard. Calculate savings, analyze usage patterns, and monitor uptime.
Learn more →Unlimited Usage
Pay for the hardware once and process an unlimited amount of AI requests without anymore token costs
Advanced Fine-Tuning
Native support for Low-Rank Adaptation (LoRA) adapters on top of base models for specialized tasks and fine-tuning.
Automate Anything with Drag-and-Drop AI
Connect Courier directly to your n8n workflows with our custom community nodes. No complex API integrations. Just drag, drop, and automate.
- Native n8n credential and node support
- Auto-synced model library from your workbench
- Multi-modal support: text, vision, and audio
- Works with self-hosted Courier instances

Platform Configuration Guidelines
Understanding your infrastructure needs
Select multiple models for different tasks (e.g., coding, vision, and general chat). As your user base grows, you will see increased latency and degradation in user-experience if multiple models are not utilized.
Performance is determined by model quantization and available VRAM (Video Memory). Reasoning diminishes as quantization drops, possibly leading to hallucinations and other unintended side-effects.
- 4-bit: Maximum speed, lower VRAM
- 8-bit: Balanced speed and logic
- 16-bit: Maximum reasoning capability
Parameters are the internal variables the AI learns during training. A 30 billion (30B) parameter model has more "knowledge" than an 8B model.
The context window is the amount of text (tokens) the AI can "remember" during a conversation or process in a single request.
Courier Model Information
Courier offers 2 different types of models depending on your use-case
Flex models load into memory upon request and unload after 5 minutes of inactivity.
• Enables running multiple large models on limited hardware
• Dynamic memory allocation
• Only the largest flex model counts towards VRAM requirements
Static models stay loaded in memory at all times, providing instant response.
• Instant availability, no load time
• Continuous memory occupancy
• Each static model adds directly to total VRAM requirements
