A Practical Gateway for Developer Workflows
DeepSeek-V4.io is an independent third-party chat and paid API gateway. It is not the official DeepSeek website and is not affiliated with or endorsed by DeepSeek.
Our Mission
Make text-based model access easier to evaluate and connect to supported apps, coding agents, and API clients through clear, testable setup paths.
Our Vision
A world where AI agents work alongside humans as collaborative partners in creativity and problem-solving.
Independent Service
A third-party product with its own accounts, balances, API keys, documentation, and support boundaries.
Our Approach
Document supported protocols and limits, then improve the path from setup to a successful request.
Our Impact
Help developers evaluate the service with transparent pricing, usage records, and concrete integration guides.
Our Story
Developers often need the same text model workflow to work across a web chat, OpenAI-compatible clients, Responses-based agents, and Anthropic-compatible tools.
DeepSeek-V4.io provides an independent gateway layer for the interfaces documented on this site. Upstream provider credentials and routing remain server-side; a DeepSeek-V4.io purchase does not fund an official DeepSeek or OpenRouter account.
The public gateway currently exposes deepseek-v4-flash for text input. Capabilities, pricing, and integration availability are stated on the relevant product and documentation pages rather than implied from the DeepSeek name.
