DeepSeek V3 vs GPT-5 mini
DeepSeek V3 wins on price. GPT-5 mini wins on reliability, ecosystem, and enterprise trust.
DeepSeek V3 costs $0.27/M input — roughly the same as GPT-5 mini ($0.25/M) but with much higher raw capability (closer to GPT-5.4 quality). The catch: DeepSeek is hosted by a Chinese company, has higher TTFT, and lacks enterprise SLAs. For teams comfortable with the trade-offs, DeepSeek V3 is one of the best value models available.

Frequently Asked Questions
Is DeepSeek V3 safe to use in production?
Technically yes, practically it depends on your risk tolerance and jurisdiction. DeepSeek's servers are in China — this creates data sovereignty concerns for regulated industries (healthcare, finance, government). For non-regulated applications with no sensitive data: the quality-per-dollar case is compelling. Consult your legal team for regulated use cases.
