DeepSeek
China-based AI model provider and assistant focused on low-cost reasoning, coding, long-context API workflows, open-weight models, and OpenAI/Anthropic-compatible developer integration.
TLDR
Decision summary
Try: Worth trying for technical teams wanting low-cost reasoning, coding, or open-weight experiments; not a default for sensitive or regulated data until China data-handling, opt-out, retention, and compliance are reviewed.
Best use
- Reasoning
- Coding
Skip or wait if
- Teams that need a globally managed AI workspace with mature admin, SSO, retention, and procurement controls
- Sensitive work where data processing and storage in the People's Republic of China is not approved
- Pricing posture
- API pricing is usage-based per 1M tokens. DeepSeek V4.1-Flash-1017 is served as deepseek-flash, while deepseek-v4-pro remains a separate listed model. Search and Fetch each cost $0.75 per 1,000 successful requests, separate from model-token charges.Read full pricing details
- Privacy/security
- High: DeepSeek's privacy policy says the services are provided and controlled by Hangzhou DeepSeek Artificial Intelligence Co., Ltd.; it collects account data, user inputs, uploaded files/photos, device/network data, logs, approximate location, and payment data, and directly collects, processes, and stores personal data in the People's Republic of China.
- Main caveat
- DeepSeek can be excellent for model experiments, coding, and API economics, but company data policy must account for China-based processing and storage before sensitive data is used.

- DeepSeek is best evaluated as a model/API and reasoning/coding option, not just as a consumer chatbot.
- DeepSeek V4.1-Flash-1017 is served as deepseek-flash with native vision; the current official pricing table lists deepseek-v4-pro separately and says retired V4 Flash aliases route to V4.1 Flash.
- The October 28 official pricing check resolves the earlier September V4 Pro ambiguity: deepseek-v4-pro is currently listed as a separate billed model. Verify the live mapping and rates again before a production migration.
- Search and Fetch are standalone web-retrieval APIs charged per successful request, not per result. Budget both calls and model tokens, and verify retrieved sources independently before consequential decisions.
- DeepSeek says server-side Search and Fetch calls through DeepSeek Harness, Claude Code, and Codex start per-request billing on October 31, 2026 at 16:00 UTC; do not extrapolate the temporary free period into ongoing agent costs.
- Use DeepSeek when API cost, long context, reasoning, open-weight experiments, or developer integration matter; use ChatGPT or Claude when a polished global workspace, team controls, files, connectors, and enterprise procurement matter more.
