One base URL and key work with virtually any app, SDK or self-hosted chat client that supports a custom API address.
Route requests to OpenAI models, Claude, Stability diffusion, Azure TTS and vector database services from a single account.
Consumption is metered in points with a published multiplier, so you pay for what you use rather than a flat subscription.
Identical request bodies return cached answers for free for 24 hours, and a header can disable caching when freshness matters.
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.

Provides stronger multi-modal reasoning and agentic tools, but lacks DeepSeek's ultra-low-cost API pricing.
#1
Offers an enormous context window and deep Google ecosystem integration, but feels less specialized for pure reasoning tasks.
#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.
