DeepSeek V4 Pro

Currently unavailable on TopxAI. Since October 25, 2026, new requests for deepseek-v4-pro are no longer accepted. This page is kept as a model reference.

Model overview

DeepSeek V4 Pro was a text model for reasoning, coding and agentic work. TopxAI previously offered it on the deepseek-official route through Chat Completions, with converted Anthropic Messages support.

Its historical published limits were a 1,048,576-token combined context window and up to 393,216 output tokens. These describe the former service; they are not limits or capabilities of an API currently available on TopxAI.

API availability

New API requests for deepseek-v4-pro return HTTP 403 with permission_denied. There is no forwarding alias and no current price for this model. It is absent from the offered model catalogue. Past usage records and captured charges remain unchanged.

Moving an existing integration

Choose another available model. Review its endpoints, request parameters, context limits and prices; do not assume V4 Pro settings transfer unchanged.
Set the new model ID explicitly in your client. Check that your API key permits it and that the selected route serves it, or use an appropriate Auto-route key. Key permissions are not expanded automatically.
Test the workflows you use, including tool calls, streaming and output handling, before moving all traffic.

See API keys and routes and the API reference for integration details.
