ParseBench results indicate Opus 5 performs roughly on par with Opus 4.8, showing slight improvements in chart parsing and visual grounding but worse performance on dense tables. Gemini 3.6 Flash achieves better table results at half the price, while LlamaParse agentic outperforms Opus 5 on all fronts at one-sixth the cost. Opus 5's 8 cents per page cost and average OCR performance make it unsuitable for large-scale document parsing.
Anthropic's Opus 5 faces significant cost and performance challenges in document parsing, ceding ground to more efficient and capable rivals like Gemini Flash and LlamaParse.
