Limitations
🟥 Limited Public Access: Requires API key and account approval.
🟥 English & Chinese Focus: Less suitable for other languages.
🟥 No Hosted UI: Requires integration; not a standalone web platform.
🟥 Not Open-Source: Proprietary backend and infrastructure.
🟥 Pricing in RMB: Global users must convert and manage foreign currency.
Use Cases
➤ Code Generation: Developers use it for smart code completion and refactoring.
➤ Multilingual Summarization: Enterprises generate bilingual summaries.
➤ Knowledge Base Answers: Integrated into support tools for contextual Q&A.
➤ Academic Research: Researchers process papers and thesis content with ease.
Pricing Details
DeepSeek's models are primarily offered in two ways: as open-source models for self-hosting, and via a paid API:
⭘ Open-Source Models: Models like DeepSeek-V2 and DeepSeek Coder V2 are available for free for research and commercial use (subject to their license terms), allowing users to download and run them on their own hardware.
⭘ API Access (Pay-as-you-go): DeepSeek offers a platform with API access to their models, priced per million tokens.
▸ DeepSeek-V2 API: Priced very competitively (e.g., ~$0.14/M input tokens, ~$0.28/M output tokens), making it highly cost-effective for an advanced model.
▸ Free API Credits: New users are often provided with a number of free credits to test the API platform.
(Note: API pricing is subject to change and should be verified on the official DeepSeek AI platform website.)
Summary
DeepSeek v3 is a robust multilingual LLM that supports high-context, high-performance API usage with competitive pricing, especially well-suited for developers and enterprises in English and Chinese contexts.
