DeepSeek provides AI models through its chat service and developer API. The API lets coding tools and applications send tasks to a selected DeepSeek model.
API usage billed by model and tokens
How I use DeepSeek
I use DeepSeek Pro through ZCode. I have also built a DeepSeek-based tool for batches of drafts, outlines and structured content.
What makes it different?
Its API offers separate input and output token pricing, with different rates for cached input and the selected model.
