Together AI is a cloud platform for running and training open source AI models. It is not a web host, so a website does not belong here. What it does is give developers a fast, affordable way to use large language models and other AI through an API, or to rent GPU clusters for training. This review explains what it offers, how it is priced and which kind of builder it suits.
What Together AI offers
The platform has a few main parts. There is an inference API that lets you call popular open source models with a simple request, so you can add AI features to an app without hosting the model yourself. There is fine tuning, which lets you adapt an open model to your own data. And there are GPU clusters for teams that want to train or run large models at scale. It is built around open models rather than a single closed system, which appeals to developers who want flexibility.
Why open models matter
Open source models can be inspected, customized and run wherever you choose, which avoids being locked into one vendor. Together AI focuses on serving these models quickly and cheaply, and it invests in optimizations that speed up inference. For developers who want the freedom of open models but do not want to manage the heavy infrastructure themselves, this hits a useful middle ground. You get the openness without the operational burden of running GPUs yourself.
Pricing and developer experience
The inference API is usually billed by tokens processed, similar to other AI providers, and often at competitive rates for open models. GPU cluster pricing depends on the hardware and duration. The developer experience centers on clear APIs and documentation, so integrating models into an application is straightforward for anyone comfortable with code. It is aimed at technical users building AI features, not at beginners looking for a no code tool.
Who it fits
Together AI fits AI developers, startups and teams building products on open source models, whether through the API or by training their own. It is a poor fit if you only need to host a website, database or email, since those do not involve AI models at all. Treat it as a specialized complement to your normal host. The host runs your site, and Together AI powers the AI features behind it.

Frequently Asked Questions
Is Together AI a web host?
No. Together AI is a cloud for running and training open source AI models, not a website host. You would use a standard web host for a site, and Together AI to power AI features in your app.
What can I do with Together AI?
You can call open source models through an inference API, fine tune models on your own data and rent GPU clusters for large scale training. It covers using, customizing and training open AI models.
How is Together AI priced?
The inference API is typically billed by tokens processed, often at competitive rates for open models. GPU cluster pricing depends on the hardware chosen and how long you use it. You pay for what you use.
Why use open source models?
Open models can be inspected, customized and run without being locked to one vendor. Together AI serves them quickly and affordably, giving developers the flexibility of open models without the burden of running the infrastructure themselves.
