DeepSeek V4 Flash and DeepSeek V4 Pro are the first Workers AI models with a full one million (1,048,576) token context window. Use them for long-horizon agentic workflows, large codebases, and multi-step reasoning that exceed the context limits of every other model hosted on the platform.

DeepSeek V4 Flash is the faster, lower-cost sibling. This release supersedes the preview version with substantially enhanced agentic capabilities.

Key capabilities:

• Reasoning: Both models support thinking mode for complex, step-by-step problem-solving.
• Function calling: Build agents that invoke tools and APIs across multiple conversation turns.
• Long context: Both models support a full 1,048,576 token context window.

Both models require the Workers Paid plan or prepaid AI Gateway credits.
