What is Together AI?
Together AI is a cloud inference provider that has built a strong developer following by offering fast, affordable access to leading open source AI models without the complexity of managing GPU infrastructure. It is primarily a developer infrastructure tool rather than a consumer product, but for development teams evaluating open source models as alternatives to proprietary APIs from OpenAI and Anthropic, Together AI is a frequently recommended starting point.
The platform supports a wide range of open source models including the Llama series from Meta, Mistral models, Mixtral, FLUX for image generation, and many others. The pricing is competitive, often significantly cheaper than proprietary alternatives for comparable tasks, which has made it attractive for cost-conscious teams building AI applications.
Fine-tuning is a practical feature for teams that want to train a custom model on their own data. Together AI provides managed fine-tuning that reduces the infrastructure complexity of adapting open source models for specific use cases.
The inference speed is a consistent positive in user reviews. Together AI has invested in optimised inference infrastructure that provides fast response times, which matters for production applications where latency affects user experience.
As a US-based company, Together AI addresses the data sovereignty concern that arises when evaluating DeepSeek's hosted API for European or US organisations. Teams that want to use DeepSeek or other open source models without routing data through non-US infrastructure can do so through Together AI.
The free $25 credit for new accounts allows meaningful evaluation without upfront commitment.
How Together AI works
Together AI runs as ml inference platform software built around text and image workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web and api, with API access for teams that want to embed it into their own products.
