DeepSeek opened its own web search to developers, priced per call, alongside an update to its cheap open model
On 17th Oct'26, DeepSeek released an update to its low-cost Flash model with open weights under the MIT licence, and opened its Search and Fetch APIs to every developer at $0.75 per 1,000 calls each. Both run on DeepSeek's own search engine, and calls made from inside DeepSeek's own coding agent, Claude Code or Codex are free for DeepSeek API users until billing starts on 31st Oct'26.
What it actually means
Anyone who has built a research agent knows the model is rarely the awkward part of the bill, because the web search bolted on beside it usually comes from a separate provider with its own invoice. DeepSeek now offers both from one account, which turns its cheap model into something closer to a complete research stack and makes it easier to try without wiring up another vendor.
The free window is the part to use. Two weeks is enough to run your own research or monitoring task through it and count how many search calls a typical job makes, which is the number that decides whether $0.75 per 1,000 is cheap for you. Check the update's benchmark claims on your own work too, since they are DeepSeek's figures and nobody has tested them independently yet, and remember that queries sent to a Chinese provider's search engine are data leaving your building like any other API call.
The model is rarely the awkward part of an agent's bill; the search bolted on beside it is.
