DeepSeek V3 0324 API — Fast, Cheap, General-Purpose
The DeepSeek V3 0324 API runs DeepSeek-V3-0324, a 671B mixture-of-experts model that answers directly — strong coding, chat, and tool use at a fraction of a reasoning model's cost.
Not every request needs a model that thinks out loud. The DeepSeek V3 0324 API is the direct-answer workhorse: DeepSeek-V3-0324 is a 671-billion-parameter mixture-of-experts model that activates about 37B parameters per token, so the DeepSeek V3 0324 API replies fast and cheap while staying strong on coding, general chat, and tool use. The March 0324 refresh sharpened front-end coding, function calling, and reasoning benchmarks — a practical default when you want a good answer now, not a chain-of-thought.
You reach the DeepSeek V3 0324 API through RouterBase on the OpenAI chat-completions protocol; set the model to deepseek-v3-0324 and your client is unchanged. The DeepSeek V3 0324 API bills $0.27 per 1M input tokens, $1.10 per 1M output, and $0.07 per 1M cached reads — 5% under list, on one key that spans the whole catalog.
