How much can I save by switching from GPT-5.5 to a cheaper model?

Switching from GPT-5.5 ($5/$30 per 1M tokens) to DeepSeek V4 Flash ($0.14/$0.28) saves 97% on input and 99% on output. At 1M tokens/day, that's roughly $150/month vs $4,200/month — a savings of $4,050/month.

Are cheap AI models as good as expensive ones?
