谷歌发布Gemini 4 Argon API，输出令牌上限达100万

Google DeepMind has made Gemini 4 Argon generally available to developers, enterprises and paid Gemini subscribers. Gemini 4 Argon is a sparse mixture-of-experts frontier model from Google built for long, multi-step work. Its target domains are coding, finance, legal, science and cybersecurity. Google first announced Argon on September 30 for a small group of cyber defenders. It now reaches the paid Gemini API at $2 input and $10 output per million tokens. The key change for developers is output length: Argon can write up to 1M tokens in one response. TL;DR Size: Parameter count not disclosed (sparse MoE). 1M token window shared by input and output. Runs on: Googles cloud only, via Gemini API, AI Studio and Gemini platform. Trained on TPUs. No open weights. Performance: Leads Googles table on knowledge work, long context and video. Mixed on agentic coding. Best: 91.7% on LVBench (long video understanding). Worst: 55.0% on FrontierSWE v2, last of 4 models in Googles table. What is Gemini 4 Argon? According to the model card, Argon is a new model, not a fine-tune of an earlier Gemini. It is a large-scale sparse MoE transformer with native multimodal support. It accepts text, images, audio and video, and it outputs text. Google trained it on TPUs using JAX and ML Pathways. The knowledge cutoff is March 2026. Google has not disclosed total or active parameter counts. How does the 1M token output limit work? Google raised the output limit to 1M tokens, up from 64K on earlier Gemini models. The model card describes a combined input plus output window of up to 1M tokens. So a long prompt reduces the room left for output. Google documents a new continuation protocol for long decodes in its developer docs and enterprise docs. At introductory pricing, a full 1M token response costs $10 in output tokens. How does Gemini 4 Argon perform on benchmarks? Google compares Argon with GPT-6 Astra, Claude Fable 5.1 and Claude Opus 5.5. Argon posts the top score on most rows. DeepSWE v1.1: 77.9%, ahead of Opus 5.5 (74.2%) and GPT-6 Astra (74.1%). Vals Index: 68.90%, ranked #1 by Vals AI ahead of Claude Sonnet 5.5 (67.04%). AutomationBench: 51.3%, versus 42.5% for Opus 5.5. Harveys Legal Agent Benchmark: 19.6%, nearly 3x the next model, but still a low absolute score. GraphWalks, 256K to 1M tokens: 84.2%, versus 71.8% for GPT-6 Astra. CWE-bench v1: 68.0%, tied with GPT-6 Astra. Google also reports 87% on the ERQA embodied reasoning benchmark. Read the evaluation methodology before drawing conclusions. Most rival scores are self-reported or pulled from public leaderboards. Argons DeepSWE score is self-computed with a mini-swe-agent harness. The rival DeepSWE numbers come from system cards and a leaderboard. Where does Gemini 4 Argon fall short? Argon trails on 5 rows of Googles own table: FrontierSWE v2: 55.0%, versus 65.5% for GPT-6 Astra. Terminal-Bench 4.0: 57.4%, versus 66.4% for Opus 5.5. Terminal-Bench Science 0.1: 57.6%, versus 68.1% for GPT-6 Astra. PostTrainBench: 45.3%, versus 49.3% for Opus 5.5. OSWorld-2.0 (offline subset): 69.2%, versus 72.6% for GPT-6 Astra. The model card also lists hallucinations and occasional slowness or timeouts. Under Googles Frontier Safety Framework, Google says it cannot rule out the biological and cybersecurity critical capability levels. It reports deploying safeguards it assesses as lowering that risk.
