Not a benchmark table. This puts pricing, context, interface fit, and key visibility into one decision card.

This is an internal DeepSeek comparison, so the main question is tier, cost, context, and capability rather than provider switching.
On the listed price snapshot, DeepSeek V3.1 is cheaper on combined input and output, but real routing, discounts, and limits still matter.
DeepSeek R1 0528 has the larger context window, which helps with long documents, knowledge bases, logs, and multi-turn workflows.
Do not start with which model is absolutely stronger. Start with the boundary: cost, context, speed, quality, ecosystem, or supply stability.
If you already hold a key, the valuable check is provider identity, callable models, and whether balance, limits, or subscription status are visible.
Commercially, do not look at model names alone. Combine price, limits, region, upstream stability, and ongoing monitoring.
