Overview

What DeepSeek does

DeepSeek is an AI laboratory based in China that develops and distributes large language models. The company offers access through multiple channels: a web interface for direct conversation, mobile applications for iOS and Android, and an API platform for developers. The service has released multiple model versions (R1, V4-Pro, V3.2, V3.1, V3) with capabilities including agent functionality and integration with Responses API and Codex frameworks. The platform positions itself as a cost-effective alternative to ChatGPT and Claude, emphasizing open-weight model availability alongside proprietary versions. DeepSeek offers both free access to the conversational interface and pay-as-you-go API pricing, though specific API costs are referenced in their documentation but not publicly detailed on their main site. Users can access models via web chat at no charge, with premium features available through API consumption. DeepSeek differentiates itself through emphasis on open models and accessibility. The company has rapidly gained market share as a mainstream search term since early 2025, competing directly with OpenAI, Anthropic, and Perplexity in the conversational AI space. The platform's architecture supports both research and commercial deployment scenarios.

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about DeepSeek.

  • API pricing details not published on main site; requires visiting documentation
  • Operates from China; data residency concerns for some users versus US-based competitors
  • Web interface blocked by geoIP in some regions

Softwr does not host reviews and shows no star rating for DeepSeek, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it. Tell us if any of it is wrong.
