DeepSeek API Docs·high signal

DeepSeek released V4 Pro (1.6T total parameters, 49B activated, MIT license) and V4 Flash (284B/13B), both with 1M context. V4 Pro scores 91.2% on SWE-Bench Verified and integrates natively with Claude Code, OpenClaw, and OpenCode via a single env var config. It's the first open-weight model to ship with dedicated agentic coding agent integration documentation. DeepSeek is already using V4 Pro for its own in-house agentic coding workflows.
