llama_index · x · 2026-10-14
LlamaIndex's Jerry Liu team ran a comprehensive OCR benchmark of Gemini 4 Argon and Muse Wonder/Spark on hard document parsing tasks via OpenDocRouter.
- Table understanding: Muse Spark and Gemini 4 Argon are SOTA at their respective price points among frontier models
- Wonder and Argon are also strong at chart understanding, reading order, and formatting recognition
- OpenDocRouter added the new models; Muse Wonder shows very low latency, and Gemini's current low price is an introductory rate that will double later this year
- ParseBench highlights: meta/muse-wonder-1.0 scores 84.73 overall ($39.41/1K pages), claude-opus-5-5 84.27 ($48.82), gemini-4-argon 84.23 ($19.26), muse-spark-1.3 78.62 ($9.56)
LlamaIndex emphasizes open benchmarking while pitching its dedicated LlamaParse solution.
