These are DeepSeek's own public list prices, not VantixCloud prices. Source: api-docs.deepseek.com (the vendor's official pricing page), checked 2026-10-25. Vendors change prices; the source page is authoritative. We quote our own price one-to-one, based on your monthly volume.
Claude, GPT and Gemini are also available by quote. If you are comparing costs, set the DeepSeek official list prices above against the price OpenAI publishes for the GPT model you use today, at the same input and output token volume. Because our endpoint is OpenAI-compatible, trying DeepSeek is a base_url and model-name change, not a rewrite.
