Opus 4.8 dropped today. ParseBench results are out. ✅ Slight gains: tables, semantic formatting, layout ⚠️ Slight regressions: charts, content faithfulness 💰 Slight price/page increase Lots of alpha left in teaching LLMs to read docs like humans do. LlamaParse remains the best doc-ingestion API for AI agents.

We comprehensively benchmarked Opus 4.8 on document understanding tasks, and compared it to Opus 4.7.

It's fairly apparent that Opus 4.8 wasn't explicitly post-trained on visual document understanding: it does slightly better on tables/semantic formatting/layout, but worse on content faithfulness and more.

Full results ready on ParseBench: https://www.parsebench.ai/
