Together AI is a fast open-source model inference API. Neureus routes to open-source models too — plus GPT-4o, Claude, and Gemini — and adds RAG, agents, workflows, and batch inference on top. Same starting point, much wider surface.
Inference-only API for open-source models. Fast, with competitive per-token pricing and fine-tuning support. Stops at "here's the model output."
Multi-provider API (open-source + proprietary) plus the full application layer: RAG, agents, workflows, batch inference, composite patterns — all managed.
Neureus is 10% below OpenRouter on all paid models. Open-source models available free via Workers AI.

Together AI has first-class support for fine-tuned model hosting — upload your weights, serve them at Together's scale. Neureus doesn't offer custom model hosting.
Together also has a larger catalog of open-source base models and more granular GPU tier selection for inference. If your use case is pure open-source inference with fine-tuned variants, Together AI's specialized focus may serve you better.
Together AI's Python SDK is mature and has deeper community adoption in the ML research community. If your team is Python-first and inference-only, Together's ecosystem fit may matter.
500 Neurons/month free. No credit card. Workers AI models always free.
