DeepSeek has made its V4 Pro model publicly available, releasing it under the name DeepSeek-V4-Pro-0813 on its pricing page. The flagship model is equipped with a context window of 1 million tokens and a maximum output of 384 thousand tokens, defaulting to a thinking mode, but also providing an endpoint without thinking mode for latency-sensitive requests.
The combination of a 1 million token input and 384 thousand token output allows for processing and generating a significantly larger volume of material within a single request compared to the previous generation, which is particularly relevant for working with large codebases, extensive document corpora, and multi-stage agents.
DeepSeek has also integrated features that most agent developers expect: structured JSON output, tool calling support, Responses API, and compatibility with Anthropic-API. Furthermore, beta support for conversation prefix continuation and FIM completion has been implemented, with FIM limited to the non-thinking mode.
At the service level, endpoints compatible with both OpenAI and Anthropic are offered, allowing teams already using either standard to switch without needing to rebuild their infrastructure.
The pricing reflects a deliberate separation of tiers. The Pro model costs 0.025 yuan per million tokens when cached, 3 yuan for cache misses on input, and 6 yuan on output. In contrast, the Flash model is priced at 0.02, 1, and 2 yuan respectively, making Pro approximately three times more expensive than Flash for input and output cache misses.
Differences are also highlighted by parallelism limitations: Flash supports 2500 concurrent requests, whereas Pro is limited to 500. This ratio indicates a clearer product structure for the V4 family. Flash is geared towards high-frequency, high-throughput traffic where cost dominates, while Pro concentrates power on heavier reasoning tasks, long-context coding, and agent workflows, where the model has a greater performance reserve for use.
Nevertheless, the absolute price of Pro remains moderate by the standards of advanced models, allowing DeepSeek to offset costs after the recent price increase announcement while remaining cheaper than most foreign competitors. Thus, the V4 lineup presents a two-pronged offering: a low-cost, high-throughput Flash tier for scaling, and a more powerful Pro tier aimed at coding and agent tasks.
