ABOUT

What is Together AI?

Together AI is a full-stack platform for running, fine-tuning and deploying open models, with serverless inference, dedicated endpoints and GPU clusters. Its OpenAI-compatible API covers chat, vision, embeddings, image, video and audio workloads, while prepaid credits keep usage-based billing predictable.

BEFORE YOU SIGN UP

What you should know

✓
OpenAI-compatible model accessThe API is compatible with the OpenAI client pattern, so existing chat integrations can usually switch base URLs and model IDs rather than adopt a new interface.
✓
Broad modality coverageThe serverless catalog includes chat, vision, embeddings, image, video and audio models, alongside fine-tuning and dedicated deployment options.
△
Credits stop unexpected overagesTogether uses prepaid credits and pauses access at a zero balance. That makes spending easier to cap, but it also means an exhausted balance interrupts requests.
✕
No trial for new accountsTogether's current billing documentation says there is no free trial and that platform access requires a minimum $5 credit purchase before use.

COMMUNITY

From the forums

Developers in r/LocalLLaMA value Together AI for convenient access to large open models, low-latency APIs and configurable zero-data-retention settings. The same discussions raise questions about changing model prices, credit handling and differences between hosted and local model behavior, so teams should benchmark the exact endpoint they plan to ship.
