Model detail
DeepSeek V4 Pro
DeepSeek V4 Pro is a large-scale Mixture-of-Experts model from DeepSeek with 1.6T total parameters and 49B activated parameters, supporting a 1M-token context window. It is designed for advanced reasoning, coding, and long-horizon agent workflows, with strong performance across knowledge, math, and software engineering benchmarks. Built on the same architecture as DeepSeek V4 Flash, it introduces a hybrid attention system for efficient long-context processing. Reasoning efforts `high` and `xhigh` are supported; `xhigh` maps to max reasoning. It is well suited for complex workloads such as full-codebase analysis, multi-step automation, and large-scale information synthesis, where both capability and efficiency are critical.

Capabilities & compatibility
Unconfirmed capabilities stay "Unknown," no guesses
Tool calling
DeepSeek V4 Pro supports function and tool calls.
tools definition; the response returns tool_calls to execute and feed results back.
Structured output
DeepSeek V4 Pro can produce JSON-formatted output on demand.
response_format: { type: "json_schema" } forces valid JSON output.
Streaming
DeepSeek V4 Pro supports streamed responses.
stream: true streams tokens incrementally, so chat UIs render as they arrive.
Prompt caching
DeepSeek V4 Pro supports prompt caching under supported routing conditions.
OpenAI SDK
Call DeepSeek V4 Pro through MixRoute's OpenAI-compatible endpoint.
base_url to https://api.mixroute.ai/v1; everything else follows the OpenAI style.
