Where Together AI genuinely wins
Together's edge is the open-source ecosystem. If you need to fine-tune Llama 3.1 70B on your dataset, deploy it on a dedicated GPU instance with predictable throughput, and call it from an OpenAI-shaped endpoint — that's exactly the workflow Together is engineered for. Their pricing on OSS models tends to be the best on the market because they run their own inference infrastructure rather than reselling. The dedicated endpoint product also matters for SOC 2 / data-residency-sensitive workloads.
Where Kunavo wins
Frontier closed-source coverage and multimodal breadth. Together does not resell Claude, Gemini or OpenAI's hosted GPT — you go to those providers directly, or to an aggregator like Kunavo. The moment your product needs Claude Opus reasoning, Gemini 2.5 Pro's 1M context, or any image / video generation, Together stops being the answer. Kunavo also delivers a meaningfully lower price point on frontier models (30–70% under official list depending on the model), with one Stripe bill that covers cards, Apple Pay, ACH, Alipay and WeChat Pay — important for self-serve global products.
Use them together
These are actually complementary stacks for many production setups. Run your fine-tuned OSS model on Together's dedicated endpoint for cost-sensitive workhorse tasks (classification, embeddings, ranking), and call Kunavo for the frontier reasoning, vision and generation calls. Both are OpenAI-compatible, so most code stays the same — you switch base_url per environment.
How you pay: Together AI vs Kunavo
Together AI is unusually explicit about this, which makes the comparison easy to run. Kunavo's checkout is Stripe-native, so the list follows the buyer rather than our billing country: cards (Visa, Mastercard, Amex, JCB, UnionPay) and Apple Pay everywhere Stripe reaches, Link and Cash App Pay for one-tap repeat top-ups, Klarna and Amazon Pay, ACH bank transfer for US accounts, and Alipay and WeChat Pay for mainland China. Local rails appear by country — Pix in Brazil, Bancontact in Belgium, BLIK in Poland, EPS in Austria, MB WAY in Portugal — with Stripe converting the dollar amount into local currency on the checkout page, so a Brazilian buyer scans a Pix QR code for an amount in reais instead of hunting for a card cleared for international purchases. Its billing documentation names exactly two ways to fund an account: major credit and debit cards on Visa, Mastercard and American Express — prepaid cards refused — and ACH from a US bank account, limited to US institutions that support instant verification. That is a clean list, and a US-shaped one. Funding from Brazil, from mainland China, or from a phone rather than a bank, the card is the only door Together leaves open.
