For developers, DeepSeek offers some of the most competitive API pricing in the market, with significant off-peak discounts that can reduce costs by up to 75%.

Features & Capabilities

DeepSeek provides two main AI models through both web interface and API access. The general-purpose chat model handles everyday tasks like writing, analysis, and problem-solving. The advanced reasoner model tackles complex mathematical problems, logical puzzles, and multi-step reasoning tasks.

The platform supports file uploads for document analysis, code review, and data processing. Users can upload PDFs, images, and text files for AI analysis. The 64K context window allows for processing lengthy documents without losing important details.

API users get access to JSON output formatting, function calling capabilities, and chat prefix completion. Both models support up to 8K output tokens for the chat model and 64K for the reasoner model.

User Ratings and Testimonials

Users praise the AI for being free with no daily limits and providing detailed, accurate responses. Many find it helpful for math problems, document analysis, and learning complex topics. The "Deep Think" feature that shows the AI's reasoning process gets positive feedback.

Common complaints include frequent "server busy" errors that block access for hours. Users report file upload issues with "no text extracted" errors. Many mention the chat length limit that forces starting new conversations.

Some users note censorship issues where responses get deleted and replaced with "beyond scope" messages. The app also has stability problems with crashes and slow performance.
