Are these models actually free?
Yes. Models listed here have $0 per token pricing as published by the underlying provider. You pay nothing for inference on these models.
What is the difference between free and paid models?
Free models are typically open-weight or open-source models hosted by providers who choose to offer them at no cost. Paid models (like Claude or GPT-4o) are proprietary and billed per token.
Can I use free models in production?
Yes. Many teams run free models in production for suitable tasks. Check the context window and capability of each model — some are equivalent to paid alternatives for many use cases.
Do I need a credit card to use free models?
No. Create an account and you get access to all free models immediately with no payment required.
Is there a rate limit on free models?
Rate limits are set by the upstream provider for each model. The model detail page lists any known limits. MegaBrain does not add additional rate limiting on top of provider limits.
