Pricing
Per 1M tokens. Input price is for cache miss; cached input/cache hit price is $0.07 per 1M tokens.
DeepSeek's first-party DeepSeek-V3 announcement/API docs page explicitly states the DeepSeek-V3 API pricing from Feb 8 onward as $0.27 per 1M input tokens on cache miss, $0.07 per 1M input tokens on cache hit, and $1.10 per 1M output tokens. The current general Models & Pricing page read on 2026-08-09 lists only DeepSeek V4 models, so this is the latest exact DeepSeek-V3-specific first-party numeric pricing found rather than a current V4 price inferred for V3.
