DeepSeek-V4-Pro

DeepSeek-V4-Pro is DeepSeek's flagship reasoning model, exposed with the official catalog id `DeepSeek-V4-Pro`. CallMissed accepts `"model": "DeepSeek-V4-Pro"` on `/v1/chat/completions`. Legacy lowercase aliases may still resolve, but new integrations should use the catalog id exactly as published.\n\nCapabilities: a full one-million (1,048,576) token context window, function calling, and reasoning ("thinking") mode. It is a text-only model (no image input), built for long-horizon agentic workflows, large codebases, and multi-step problem-solving that exceed the context limits of most other hosted models.\n\nPricing on CallMissed is $1.375 per million input tokens and $4.125 per million output tokens, with cached input billed at $0.04583 per million tokens. For teams that want frontier-class reasoning plus a 1M context and native tool calling, V4 Pro is the top DeepSeek tier.\n\nUse DeepSeek-V4-Pro for codebase analysis, long-document review, and tool-using agents. Reasoning content can increase time-to-first-token; stream responses to keep UIs responsive, and set `max_tokens` generously so a long thinking phase does not truncate the answer.\n\nIntegration is OpenAI-compatible: send chat messages, define `tools` for function calling. If your client library surfaces a separate reasoning field, handle it the same way you would for other thinking models. When it profiles as overkill for easy traffic, route simpler prompts to `DeepSeek-V4-Flash`.
