Which DeepSeek models are available?
Currently available: deepseek-v4-flash, deepseek-v4-pro — both reachable through one key, billed per token.
Should I choose V4 Flash or V4 Pro?
Use V4 Flash for fast, cost-sensitive and high-volume tasks; choose V4 Pro for harder reasoning and quality-critical work.
How is it billed? Is there a minimum?
Billed per token (input + output) — see the price table above. Pay-as-you-go via Alipay, WeChat Pay, USDT and credit card, from as little as $1.
Is it OpenAI-compatible?
Yes. The endpoint is OpenAI-compatible, so it works with Cursor, Claude Code and any OpenAI SDK by changing the base URL and key.
