Together AI Freemium

Fast open-model inference, fine-tuning and GPU clusters in one API

Together AI is a cloud platform that serves more than 200 open-source models โ€” Llama, DeepSeek, Qwen, Mistral โ€” through one OpenAI-compatible API, with fine-tuning and dedicated GPU clusters on top.

What is Together AI?

Together AI, founded in 2022 by researchers from Stanford and Google Brain-adjacent circles, does inference, training and GPU rental under one roof. Because the endpoint mimics OpenAI’s format, you usually switch providers by changing a base URL and a model name.

Together AI features that matter

  • Huge model catalog: chat, image (Flux, Stable Diffusion), embeddings and rerankers.
  • OpenAI-compatible API: swap in one line for most existing code.
  • Fine-tuning: LoRA and full fine-tuning with your own data.
  • Dedicated endpoints: reserve throughput for steady production traffic.
  • GPU clusters: rent H100/H200-style instances by the hour for training.

Product highlights

For teams that want open weights without running a cluster, this is one of the few places that offers inference, fine-tuning and training compute in a single account. Latency on popular small models is competitive with the big closed APIs.

The catch is that you are on shared capacity unless you pay for a dedicated endpoint, so peak-hour throughput can wobble. If your product needs hard SLAs, budget for reserved capacity.

Who should use Together AI

Strong fit for startups that want to ship on open models and control cost per token, and for researchers who need training compute without a procurement fight. Less useful if you only ever call one flagship closed model and value simplicity over price.

Common use cases

  • Running Llama or DeepSeek at a lower cost than closed APIs.
  • Fine-tuning a domain-specific model on internal documents.
  • Generating images with Flux via the same account.
  • Borrowing GPUs for a training run without a long contract.
  • Building a provider-agnostic LLM gateway.

Pricing and limits

Inference is pay-per-token and generally cheaper than frontier closed models. Fine-tuning and GPU clusters are billed separately by the hour. New accounts typically get a few dollars of free credit to test.

Quick Summary

  • Together AI serves 200+ open models via an OpenAI-compatible API.
  • Also offers fine-tuning, dedicated endpoints and GPU clusters.
  • Pay-per-token pricing; free credits for new accounts.
  • Shared capacity unless you reserve a dedicated endpoint.
  • Best for teams standardizing on open-weight models.
