Why the high price?
Market Reality
OpenAI\'s frontier models command premium pricing. We\'re passing that cost through while offering Forge as the smart alternative at 1/9th the price with comparable quality.
Strategic Choice
GPT-5.5 Pro is here for teams that absolutely need OpenAI\'s latest. But most will find Forge delivers 90% of the value at 10% of the cost.
What to expect from GPT-5.5 Pro

GPT-5.5 Pro will be here when you need it. But right now, Forge is already delivering Opus-level quality at a fraction of the cost.
Teams switching from OpenAI to Forge report 5-10x cost savings with no quality drop. Why pay 9x more for GPT-5.5 Pro when Forge is already lit?
