I Switched from GPT-4o to DeepSeek: 10x Cheaper, Surprisingly Comparable I've been running AI APIs for my projects and the OpenAI bills were getting out of hand. $500+/month for GPT-4o for coding tasks, data analysis, and content generation. So I finally took the plunge and switched my primary model to DeepSeek V3.2. Here's what happened. The Cost Difference is Wild Model Input (per 1M tokens) Output (per 1M tokens) My Monthly Cost GPT-4o $2.50 $10.00 ~$500 Claude 3.5 Sonnet $3.00 $15.00 ~$600 DeepSeek V3.2 $0.28 $1.10 ~$45 DeepSeek V4 Flash $0.14 $0.42 ~$25 That's not a typo.
