DeepSeek V3 vs GPT-5 mini
DeepSeek vs OpenAI — head-to-head specs and pricing.
Open-weights reasoning champion, rock-bottom pricing.
DeepSeek V3 — exceptionally low per-token pricing (10x cheaper than GPT-5). WARNING: Per DeepSeek ToS, prompts and responses may be used for model training and are processed on servers in China. Not recommended for sensitive workloads (healthcare, legal, financial) or EU data-residency requirements. Use for cost-sensitive consumer workloads where privacy is not a hard constraint.
Fast, cheap, still smart.
GPT-5 mini is a smaller variant of GPT-5 optimized for throughput and cost. Great default for chat and classification.
