Flash and Pro are not interchangeable rows

DeepSeek V4 Flash and Pro are distinct model identities. Each effort level is another configuration. Combining them into one DeepSeek score would hide which variant produced the result.

Use the table to find whether quality, elapsed time, and cost point to the same configuration. When they do not, apply a task-specific quality floor before optimizing the other two.
