Then you connect that API to the tool you want: <code>curl<\/code>, Python, Node.js, OpenCode, Claude Code, Aider, Cline, Continue.dev, Open WebUI, LiteLLM, LangChain, or your own application.<\/p>\n\n\n\n<p>As of DeepSeek\u2019s current API docs, the main API models are:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>deepseek-v4-pro\ndeepseek-v4-flash\n<\/code><\/pre>\n\n\n\n<p>Older model aliases like:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>deepseek-chat\ndeepseek-reasoner\n<\/code><\/pre>\n\n\n\n<p>are marked by DeepSeek as compatibility names and scheduled for retirement on <strong>2026-07-24<\/strong>.
