Description

DeepSeek V4 Pro is a reasoning model from DeepSeek. Webparam does not stock this model yet and can source it on request — tell us what you need it for and we will come back with availability and a price. DeepSeek’s stated focus is open-weight frontier reasoning at disruptive economics. The weights are not published, so it is API-only.

Capabilities

Tool calling
Calls functions you define and returns their arguments as structured data, the basis of agents.
JSON mode
Constrains the response to valid JSON matching a schema you supply.
Streaming
Emits tokens as they are generated, so answers appear progressively rather than all at once.

  • Open weights permit self-hosting later
  • Price quoted from the supplier's own rate card, not estimated

Weaknesses

  • Priced at 2x during the supplier's peak hours
