Access

No authentication required — core checks work right away.

DeepSeek is the language model Seyka runs on right now, not on a roadmap. When you ask about keywords, competitors in the results, or a site audit, this is the model answering: it holds the conversation, breaks the task into steps, and decides which tool to call.

Behind the name is a company of the same name from Hangzhou, China, founded in 2023 and grown out of the High-Flyer quant fund. Its models are known for frontier-level quality at a fraction of competitors' cost.

What it is

DeepSeek is a family of open-weights large language models. The current generation as of mid-2026 is DeepSeek-V4 (April 2026), in a more powerful Pro variant and a fast, economical Flash variant, both with a context window of up to 1 million tokens. Its signature feature is a built-in reasoning mode ("Thinking"): the model can unfold intermediate steps before answering a hard question, with no switch to a separate model. The weights are published on Hugging Face under an MIT-style license, so the model can also be deployed on your own infrastructure.

What you get

Because Seyka runs on DeepSeek in production, its low cost per answer is not a line on a price list — it lets Seyka run more queries and analyse the results more fully instead of cutting an analysis short. The model's strong Russian means it reads Runet phrasing and local SEO specifics directly rather than through English, and its reasoning mode keeps multi-step audits from skipping a step.
