Understand the key concepts that power ARKA-AI: workspaces, BYOK, ARKAbrain routing, and tools.
ARKA-AI is built around four core concepts that work together to provide an intelligent, cost-effective AI experience:
Use your own API keys from OpenAI or OpenRouter for full control over costs and model access.
Intelligent system that automatically selects the best AI model for each task.
Pre-configured AI tools optimized for specific tasks like writing, summarization, and SEO.
Organize your tools, conversations, and settings in dedicated workspaces.
Unlike traditional AI platforms that charge markups on API usage, ARKA-AI uses a Bring Your Own Key model. You connect your own API keys from AI providers and pay them directly at their published rates.
OpenAI
GPT-4o, GPT-4o Mini, GPT-4 Turbo, o1 Mini
OpenRouter
Claude 3.5 Sonnet, Gemini 1.5, Llama 3.1, DeepSeek, and more
Add Multiple Keys
Add keys from both OpenAI and OpenRouter to unlock the full range of models. ARKAbrain will automatically select from all available models based on the task.
ARKAbrain is ARKA-AI's intelligent routing system. Instead of manually choosing which AI model to use, ARKAbrain analyzes your request and automatically routes it to the optimal model.
Task Classification
ARKAbrain analyzes your input to identify the task type (writing, coding, summarization, etc.) and complexity level (low, medium, high).
Model Selection
Based on the task, it selects a model role (FAST_CHEAP, BALANCED, REASONING, CODING, etc.) and picks the best available model from your configured providers.
Execution with Fallback
The request is sent to the selected model. If it fails, ARKAbrain automatically tries fallback models until it succeeds.
ARKAbrain categorizes models into roles based on their strengths:
| Role | Primary Model | Use Case |
|---|---|---|
| FAST_CHEAP | GPT-4o Mini | Simple, quick tasks |
| BALANCED | GPT-4o | General purpose |
| REASONING | o1 Mini | Complex analysis |
| CODING | GPT-4o | Code generation & debugging |
| LONG_CONTEXT | Gemini 1.5 Pro | Large documents (up to 2M tokens) |
| SEO_WRITER | GPT-4o | SEO content & marketing |
ARKA-AI provides pre-configured tools that are optimized for specific tasks. Each tool has a custom system prompt and recommended settings that ensure the best output quality.

Workspaces are containers for your ARKA-AI activity. Each workspace has its own:
Most users only need one workspace. Create additional workspaces if you want to separate personal and work usage, or use different API keys for different projects.
ARKA-AI is designed with security as a priority:
API keys are encrypted with AES-256-GCM before storage. We never log or expose your actual key values.
Your prompts go directly to the AI providers. ARKA-AI orchestrates the routing but doesn't store your content.
