(70% OFF) I Tested 10 AI Models on ONE Coding Task — The Price Gap Is INSANE (One API, Real Costs)

Try Oxyy: https://oxyy.ai Promo code PROMPTENGINEER70 70% off purchases of $50 or more (minimum purchase $50) I gave 10 AI models the same coding job through one API key and wrote down what every answer really cost: a regular-expression engine written from scratch, graded by 80 hidden tests. Highlights (my tests, one run per model, list prices unless stated): - 7 of 10 models scored 80/80 on the regex task. - Claude Haiku 5.5: $0.0043. Claude Opus 5: $0.2834. Same score. - DeepSeek V4 Flash: 60/80 (counted repeats fail). GLM-5.2: 0/80 (ran out of tokens). Grok 4.7: no score (timeouts, then 503). - Billed price = 40% of list on my account (launch promo). Whole project: about $1.02 across 59 requests. - Second runs of the same prompt varied by about a third in tokens and cost. Narration uses an AI clone of my voice.
