Key Takeaways
- Together AI is a cloud platform for building, fine-tuning, and running AI models.
- It offers fast, cost-optimised inference, GPU compute, and fine-tuning for open models.
- Aimed at developers and AI companies building production applications.
- Powerful infrastructure; you still bring the engineering to build the product.
Together AI provides the infrastructure that AI applications run on — fast, cost-optimised inference, GPU compute, and fine-tuning, with a strong focus on open models. For developers and companies building AI products, it offers an alternative to running your own hardware or relying solely on the big closed providers, with research-driven optimisations for speed and cost.
What is Together AI?
Together AI is an “AI-native cloud” for the full lifecycle of AI development. It offers serverless and dedicated inference, batch processing, GPU clusters and managed storage, and fine-tuning and pre-training support. Research-driven optimisations aim to deliver faster inference at lower cost, and it emphasises open models, making it popular with teams that want flexibility and control over the models they run.
What it does well
- Inference — fast, cost-optimised serverless and dedicated model serving.
- Compute — GPU clusters and storage optimised for AI workloads.
- Fine-tuning — customise open models on your own data.
- Open models — strong support for running open-source models.
- Optimised — research-driven speed and cost improvements.
Who it is for
Together AI suits developers, startups, and AI companies building production applications that need flexible, cost-effective infrastructure — especially those working with open models or wanting more control than a single closed provider offers. It is aimed at technical teams comfortable building AI products on cloud infrastructure.
Things to keep in mind
Together AI provides powerful infrastructure, but you still need the engineering to build a real product around it, including choosing models and verifying outputs. As with any inference and compute provider, understand how usage maps to cost at scale, and confirm the specific models and capabilities you need are supported.
Our verdict
Together AI is a strong choice for teams that want flexible, cost-effective AI infrastructure with a focus on open models. Its combination of optimised inference, compute, and fine-tuning gives developers real control over how they build and run AI. Bring the engineering, mind your costs at scale, and it is a capable foundation for production AI applications.
Frequently asked questions
