# DeepSeek releases V4-Pro with 1M token context and agent focus

> DeepSeek has officially launched V4-Pro, moving it out of the preview it had run since April. The model offers a 1 million token context window, outputs of up to 384,000 tokens, and switchable thinking and non-thinking modes, with the pitch built around multi-step agent workflows for research and development rather than simple chat. The Chinese lab also adjusted pricing, introducing peak and off-peak billing where off-peak usage runs at half the peak rate, a nod to the compute economics behind long-context, agent-heavy work. It is available through DeepSeek's app, web interface, and API. DeepSeek matters out of proportion to its size because it keeps landing capable models that pressure the cost assumptions of US labs. A million-token context aimed squarely at autonomous agents, priced aggressively, is the kind of release that forces competitors to justify their margins. For anyone watching the US-China model race, this is another data point that the frontier is not a one-country club, and that open and cheap can be its own competitive weapon.
