DeepSeek V4

DeepSeek V4 is a large language model first observed on February 23, 2026, from the Chinese AI developer DeepSeek. The entity is also referenced under the aliases DeepSeek v2, DeepSeek-V4, and V4 model, indicating possible naming inconsistencies in early documentation. At launch, the company published commercial API pricing of $0.30 per million input tokens and $0.50 per million output tokens. As of late February 2026, DeepSeek has not released architecture details, parameter counts, training data specifications, or standardized benchmark results for independent verification, leaving its technical profile undefined against contemporaneous models. This release matters because it represents the latest move in an accelerating price war among foundation-model providers, with DeepSeek V4’s token costs positioned below many Western competitors at announcement. For enterprises and developers evaluating inference providers in early 2026, the model offers a low-cost option whose real-world performance remains unmeasured by third-party audits, making procurement decisions dependent on undisclosed capabilities.
