DeepSeek is a Chinese AI lab (Hangzhou DeepSeek Artificial Intelligence Co., Ltd.), founded in 2023, known for the V3 and R1 open-weight model families that hit frontier-level performance at unusually low training cost. On OpenKey it offers 11 models spanning three lines: the V3/V3.1/V3.2 chat series for general use, the R1 series for reasoning-heavy tasks, and a distilled R1-on-Llama-70B variant for cheaper inference. The newest release, DeepSeek V4 Flash, pushes context to over 1M tokens. None of DeepSeek's models are free on OpenKey, but pricing across the lineup stays well below most frontier competitors, which is the core of their strategy: near-frontier capability at commodity prices.
Lineup
For general chat and coding, DeepSeek V3.2 ($0.2288/$0.3432 per 1M in/out, provider price) is the current mainline model with a 131K context window. If you need deep reasoning (math, multi-step logic), use R1 0528 ($0.50/$2.15 per 1M) — it's the most capable reasoning model in the lineup, though pricier on output. For the cheapest option, DeepSeek V4 Flash runs $0.09/$0.18 per 1M with a 1,048,576-token context window, making it the best pick for large-document or long-context jobs on a budget. Skip the older R1 Distill Llama 70B ($0.80/$0.80) unless you specifically need a distilled, self-hostable-style checkpoint.
