You run chat or RAG with models up to 13B in Portuguese, predictable volume. Critical privacy. Want stable latency with no shared API queue.
Technical comparison
Ollama, Together.ai or RunPod: which to choose for open-source LLM?
Hosting Llama 3, Mistral, Qwen and other open-source models became common strategy in 2026 — be it for cost, privacy or customization. The three main options: run Ollama on VPS/CPU, use a managed API like Together.ai, or rent GPU on-demand at RunPod.
TL;DR
Ollama on Rollin VPS (CPU) runs small quantized models (Llama 3 8B, Phi-3, Qwen 2.5 7B) with stable latency, no API queue, and fixed cost of R$ 169.90-439.00/month. Together.ai is a managed API with fast inference and per-token pricing, no ops. RunPod offers GPU on-demand for large models (70B+) or fine-tuning.

When to choose each
Use Together.ai if:
You need Llama 3 70B without investing in GPU. Variable loads — prototypes, peaks. Small team without DevOps.
Use RunPod if:
You will do fine-tuning. Need GPU for specific workloads. Want full environment control.
Use combination if:
Ollama on Rollin VPS for production + Together.ai for fallback on large models + RunPod for fine-tuning.
Verdict
For most Brazilian cases, Ollama on Rollin VPS delivers the best cost-benefit with total privacy and stable latency. Honestly, if you need 70B+ model, Together.ai is clearly superior. RunPod is the right tool for fine-tuning. Rollin Host does not offer dedicated GPU in 2026, so if your case is serious fine-tuning, use RunPod without guilt.
