Why DeepSeek is this cheap
DeepSeek pioneered the MoE (mixture-of-experts) training stack that activates only ~37B parameters per token despite a much larger model. Combined with aggressive batched inference and Chinese cloud GPU costs, the unit economics dominate every Western frontier provider. The catch: data residency and export-control concerns mean some teams can't use the hosted API directly.
When to pick DeepSeek
Use V4 Flash as your default tier for anything that isn't customer-facing legal/medical/financial output. The savings vs GPT-5.5 or Claude Sonnet 4.6 typically pay for a full retry budget — if Flash misses, retry on a frontier model and you still come out 5–10× cheaper overall. See the cost cutting playbook for the cascade routing logic.
