Frequently asked questions
Everything you need to know about Arbinex
Arbinex analyzes your query to understand its nature, whether it's creative writing, code generation, factual research, or reasoning. Based on this analysis, it automatically selects the models best suited for your specific task. You can also manually select models if you prefer.
Yes, Arbinex operates on a "Bring Your Own Keys" (BYOK) model. This means you pay directly to the AI providers (OpenAI, Anthropic, Google, etc.) at their standard rates with no markup from us. This gives you complete cost transparency and control.
Arbinex queries multiple models in parallel, then uses a synthesis model to analyze all responses. It identifies the best elements from each response and combines them into a single, optimal answer. You can also view individual model responses if you prefer.
We support all major LLM providers including OpenAI, Anthropic, Google, Grok and Perplexity. We continuously add new models as they become available, and will add more LLM providers in the future.
Your queries are sent directly to the AI providers using your own API keys. We don't store your conversations on our servers. Your data privacy is governed by the terms of service of each AI provider you use. API keys are encrypted at rest using Supabase Vault with pgsodium (AES-256-GCM encryption).
Absolutely! Our Team plan includes team workspaces, SSO/SAML authentication, dedicated support, and custom integrations. Contact our sales team to discuss your specific needs.
About Arbinex
The power of many AI models in one platform
Our Mission
We believe the best AI response shouldn't depend on which company you're locked into. Arbinex gives you access to all leading AI models through a single interface, automatically selecting the best for each task.
Who We're For
Developers, researchers, writers, and anyone who relies on AI daily. If you've ever wondered "would GPT, Claude or Gemini be better for this?" Why choose? With Arbinex you can compare the response from all, pick a winner or merge them into one.
Our Approach
Transparent pricing with no token markup. Your API keys, your data, your control. Instead of hopping from one LLM provider to another, just use them all together in one place.
