Together AI is a great choice for fast open-source model inference. Plugsky is the alternative for teams that need similar model access PLUS GCC data residency, sovereign deployment, and a flat monthly bill instead of per-token.
What Together AI does well
- Fast inference for the long tail of open-source models (Llama, Mistral, Qwen, etc.)
- Per-token pricing with usage-based billing
- Fine-tuning for open-source base models
- Serverless endpoints for quick experiments
What Plugsky adds
- Flat monthly pricing on self-serve plans ($20-$120)
- GCC data residency with dedicated me-central-1 region and GCC entity
- Sovereign deployment — air-gapped, customer-managed keys, customer data center
- OpenAI-compatible API — works with any OpenAI SDK
- Arabic-native model (plugsky-arabic)
- Enterprise controls — SAML SSO, SCIM, audit log, dedicated CSM

When to pick which
- Pick Together AI if you want the absolute lowest per-token price on open-source models and you don't need GCC residency or sovereign deployment.
- Pick Plugsky if you need model access PLUS data residency, sovereign deployment, or a flat monthly bill. Or if you want one OpenAI-compatible endpoint that works with any OpenAI SDK.
Frequently asked questions
Can I use Plugsky and Together AI together?
Yes. Use Together AI for the long tail of open-source models and Plugsky for high-volume, sovereign-deployable core workloads.
Does Plugsky fine-tune?
Yes, on Enterprise contracts. We fine-tune open-source base models (plugsky-gpt-oss, plugsky-llama) on your data and deploy the result in your tenant.
What about inference speed?
Plugsky uses NVIDIA NIM and opencode.ai Zen/Go stacks — comparable to Together AI for most models. For latency-sensitive workloads, we offer reserved capacity.
Is the API the same?
Plugsky is OpenAI-compatible. Together uses its own API. If you want OpenAI SDK compatibility, Plugsky wins. If you want the absolute widest model selection, Together wins.
