Strengths

  • Google's flagship reasoning model, built for complex software engineering, maths and science, and autonomous multi-step agents
  • Vals Index 68.9%, ahead of GPT-6 Astra, Claude Fable 5.1 and Claude Opus 5.5 in Google's reported comparison
  • Leads Finance Agent v2 (65.4%), Vibe Code Bench (91.9%) and DeepSWE v1.1 (77.9%) among the compared frontier models
  • 1M-token unified context window with 64K output on Elosia
  • Natively multimodal input covering text, images, video, audio and PDFs, with strong long-video understanding (LVBench 91.7%)
  • 15.1% hallucination rate on AA-Omniscience, far below GPT-6 Astra (51.3%) and Claude Opus 5.5 (58.6%) as measured by Artificial Analysis

Limitations

  • Thinking has no off setting (low, medium or high only) and produces long reasoning outputs, which raises latency and output cost
  • Explicit context caching is not supported, only implicit caching
  • Google publishes no GPQA Diamond, MMLU, AIME or SWE-bench Verified score; its reported suite is built around agentic and domain evaluations
  • Google's figures are self-reported and the Humanity's Last Exam score comes from Artificial Analysis; Argon ranks last of the four models Google compares on Terminal-Bench 4.0 and on FrontierSWE v2
  • AA-Omniscience factual accuracy of 50%, below Gemini 3.1 Pro Preview and GPT-6 Astra
