What models are supported?

We support the latest and most capable models from all leading platforms, including OpenAI, Anthropic, Google, Meta, and DeepSeek. Our system is designed to integrate new models within hours of their public release.

How does the credit system work?

Each plan comes with a set amount of monthly credits. Credits are consumed based on the token usage of the models you interact with. We bill in micro-credits to ensure you only pay for what you actually use.

How does the credit system translate to tokens?

Credits map directly to raw token consumption. For example, $10 of credits corresponds to roughly 1 million input tokens of GPT-4o, or up to 60 million input tokens on our open-source models. View the Benchmarks section for detailed conversion rates.

Is there a free trial?

Yes! Every new account automatically starts with a 7-day Developer plan trial at no cost — 200 credits included. You get full access to multi-model comparison, API key support, and cost visibility. After 7 days, choose Personal ($10/mo) or Developer ($20/mo) to continue.

Can I cancel my subscription at any time?

Absolutely. You can manage your subscription through our billing portal and cancel at any time. Your credits will remains active until the end of your billing cycle.
