High-efficiency open-weight and hosted reasoning AI powered by DeepSeek-V4 and R1 at ultra-low token costs.
Leverages a sparse Mixture-of-Experts architecture (49B active parameters out of 1.6T on V4-Pro) to process up to 1 million tokens with minimal latency and memory overhead.
Pioneered by DeepSeek-R1 and integrated into V3.2 and V4 thinking modes, exposing step-by-step self-verification for complex math, logic, and code debugging.
Drops input token costs to $0.003/1M on Flash and $0.022/1M on V4-Pro for cache hits, with 50% lower rates during off-peak UTC hours.
Provides free access at chat.deepseek.com and on iOS/Android with document uploads, reasoning mode, and web search without paywalling core models.

A next-generation AI platform for creation, research, and delivery
Interact with a language model through conversation for questions, drafting, and analysis across many topics.
Use the model to generate and refine text and other content for writing, ideation, and delivery.
Support development work with code generation and explanation to speed up everyday engineering tasks.
The model is built to interpret natural-language requests and reason through multi-step problems.

#1
Google's multimodal AI assistant powered by Gemini 4 Carbon (Gemini Carbon 4), Gemini 4 Argon, and Gemini 3.8 Flash with a 1M-token context window and Workspace integration.
#2Delivers superior long-form coding artifacts and nuanced writing, but lacks DeepSeek's specialized open-weight reasoning models.

Features real-time X social data integration, but is less cost-effective for dedicated developer coding workflows.
SpecialistReal-time AI answer engine and research workspace combining live web citations with frontier reasoning models.

Free / Open-sourceProvides comparable open-weight foundation models and multilingual performance, but requires self-hosting or third-party inference setup.
