Together AI
Together AI provides hosted model inference and infrastructure for developers who want to use open models without operating the serving system themselves. Serverless inference, dedicated endpoints, fine-tuning, and evaluation are different services with different cost structures. It is a paid developer platform, so it does not belong in a list of unrestricted free APIs.
Start with one inference task
Choose a model that supports your input and required output. Create an API key, run a small request through the documented SDK, and check the response against a known example. For an extraction application, validate missing fields and malformed output before processing a larger dataset. Estimate input and output token costs separately. A fine-tuning job or dedicated endpoint also needs its own cost estimate.
Credits and current access requirements
Together’s current billing documentation says there is no free trial. An organization’s first credit purchase must be at least $15; later purchases have a $5 minimum. An older official help article still describes a general $5 minimum, so confirm the amount shown in the first-purchase screen. This page follows the current billing documentation.
Usage consumes a prepaid balance. API access is suspended if that balance reaches zero. Auto-recharge can create further purchases when configured. A low per-token model price does not make dedicated compute, training jobs, or every model free. Review the pricing page for the exact model and service before committing a workload.
