DeepSeek Pro
A flagship large language model from DeepSeek, featuring strong planning and reasoning capabilities. It is suited for planning and review stages within multi-agent workflows.
Timeline (last 90 days)
In the honesty test, the number of confident wrong answers was: Opus one, Sonnet four, DeepSeek Flash eighteen, and DeepSeek Pro twenty-six.
In the closed-book test, all four models scored 0 on news questions from the most recent month.
A reasonable strategy is to use DeepSeek V4.1 Flash for rapid prototyping and lightweight 3D scenes, leave long-horizon complex projects to more mature closed-source models, and keep an eye on the Pro version.
On ten objectively scorable programming problems, DeepSeek Flash was correct 10/10 and DeepSeek Pro was correct 8/10; median response time was 0.83 seconds for Flash and 1.29 seconds for Pro.
DeepSeek Pro ranked fourth and is one of the engineer's daily workhorses for agentic workflows, commonly used in the planning and review phases.
GLM 5.3 ranked third, and the engineer alternates between DeepSeek Pro and GLM 5.3 for the planner and reviewer roles.
In the elemental sandbox test, MiMo-V2.6 Pro scored 8 points thanks to its visual expressiveness and complete translation, while DeepSeek Pro scored only 6 points due to untranslated menus.
DeepSeek's Pro model has an activation ratio of approximately 3% (49B activated / 1.6T total parameters), which is a typical characteristic of MoE architecture.
DeepSeek Pro's 1.6T total parameters with 49B activated parameters result in inference costs comparable to a roughly 49B dense model, while expanding knowledge capacity by approximately 32 times.
V4.1 Flash off-peak pricing (per million tokens): cache hit 0.02 yuan, cache miss 1 yuan, output 4 yuan.
