  "text": "We benchmarked GPT-5.5 on document understanding 📄📊\n\nWe ran it through ParseBench, our comprehensive OCR benchmark over enterprise documents. We evaluated metrics across various dimensions: visual grounding, tables, charts, and more.\n\nWe evaluated GPT-5.5 on mid thinking and zero-thinking modes. When compared against GPT-5.4 (0 thinking) and Opus 4.7 (adaptive thinking):\n📈 GPT-5.5 wins on tables\n📈 GPT-5.5 wins on visual grounding\n📉 GPT-5.5 0-thinking does worse on charts than GPT-5.4 0-thinking\n📉 Higher thinking does worse than lower thinking of content faithfulness, semantic formatting\n📉 Opus 4.7 wins overall on content faithfulness and semantic formatting\n💸 GPT-5.5 is expensive: 13c per page at mid-thinking modes and 5.93 at 0-thinking! This is 5x the cost of any competitive OCR solution.\n\nConclusion: GPT-5.5 is one of the better frontier models out there in terms of pure accuracy, but def not pound for pound w.r.t price.",
