Use-case routing table

The search intent
DeepSeek V4 Pro vs Claude 4.6 searches usually come from buyers who already understand Claude's review reputation and want to know whether DeepSeek can become the default. The practical answer is a routing policy, not a universal winner.
How to split the workload
DeepSeek V4 Pro belongs on coding, debugging, refactoring, and repeated agent steps. Claude belongs on selective final review, complex document synthesis, and tasks where tone or nuance are more important than raw throughput.
Commercial framing
The CTA should stay DeepSeek-led. Claude can be mentioned as a premium fallback, but it should not be presented as a purchasable plan unless actual stock exists.
