Gemini 4 Argon: Google is back among the top three labs in intelligence achieved

Google DeepMind's Gemini 4 Argon scored 53 on the Artificial Analysis Intelligence Index with high reasoning, matching OpenAI's GPT-6 Astra (max, 53) and edging GPT-6.1 Sol (max, 52), according to Artificial Analysis. At its current 50% launch discount and 95% cache discount, Gemini 4 Argon costs $1.99 per Intelligence Index task, 60% of GPT-6 Astra (max, $3.26), rising to $3.98 at standard pricing of $4/$20 per 1M input/output tokens. The model, Google's first proprietary release above the Flash class in over 7 months, is rolling out to selected users only, with a 1M-token context window and a 15% hallucination rate on AA-Omniscience, the lowest among models scoring 45+ on the Intelligence Index.

September 30, 2026 Gemini 4 Argon: Google is back as one of the top three labs in intelligence achieved See model page https://artificialanalysis.ai/models/gemini-4-argon Google’s new Gemini 4 Argon equals GPT-6 Astra on the Artificial Analysis Intelligence Index at 60% of the Cost per Task with discounted prices Gemini 4 Argon is Google DeepMind’s first proprietary model above the Flash class in over 7 months. With high reasoning the highest available , it scores 53 on the Artificial Analysis Intelligence Index, matching GPT-6 Astra max, 53 and 1 point ahead of GPT-6.1 Sol max, 52 , with gains driven by lower hallucinations and stronger agentic capabilities. At its current 50% pricing discount and with cache discounts increased to 95%, Gemini 4 Argon costs $1.99 per Intelligence Index task, 60% of GPT-6 Astra max , but 2.7x GPT-6.1 Sol max . After the discount ends, this will rise to $3.98 ~1.2x GPT-6 Astra max . Gemini 4 Argon is currently being rolled out to selected users and is not publicly available. The 50% discount is an initial promotion. Google has not yet confirmed the promotion end date Key benchmarking results for Gemini 4 Argon with high reasoning: ➤ Google returns as one of the top three labs on intelligence: Gemini 4 Argon high scores 53 on the Artificial Analysis Intelligence Index, matching GPT-6 Astra max, 53 and 1 point ahead of GPT-6.1 Sol max, 52 . This is 23 points above Google’s previous non-Flash model, Gemini 3.1 Pro Preview 30 and 12 points ahead of Gemini 3.8 Flash high ➤ Launch discounts of 50% make Gemini 4 Argon competitive on Cost per Task: At current discounted pricing, Gemini 4 Argon high costs $1.99 per Intelligence Index task, 60% of GPT-6 Astra max, $3.26 for a comparable level of intelligence. This cost efficiency is driven by lower token prices, rather than reduced token use, with Gemini 4 Argon averaging 62k output tokens per task, compared with 27k for GPT-6 Astra max . Google has not yet confirmed the promotion end date, but on standard pricing, Cost per Task will increase to $3.98 ➤ Stronger agentic performance: Historically a weaker area for Gemini models, Gemini 4 Argon shows improvements across agentic evaluations. It ranks 1 on AutomationBench-AA at 78%, 7 points ahead of Claude Sonnet 5.5 max, 71% . On Terminal Bench 4, Gemini 4 Argon achieves 57%, a + 53 point improvement from Gemini 3.1 Pro Preview, only behind Claude Sonnet 5.5 max, 64% , Claude Opus 5.5 max, 60% and GPT-6 Astra 59% . On AA-Briefcase, it reaches 1494 Elo. This is driven by a 65% rubric pass rate, the highest we have recorded, but lower Analytical Quality 1576 Elo and Presentation Quality 1308 Elo ➤ Lowest hallucination rate among leading models: On AA-Omniscience, Gemini 4 Argon has a 15% hallucination rate, the lowest of any model scoring 45+ on the Intelligence Index, compared with 51% for GPT-6 Astra max and 54% for GPT-6.1 Sol max . This means Argon is much more likely to acknowledge when it does not know an answer rather than guess incorrectly. On accuracy, Gemini 4 Argon scores 50%, a 5 point decrease from Gemini 3.1 Pro Preview, and 13 points below GPT-6 Astra max, 63% . With this slightly lower accuracy, its overall AA-Omniscience score of 42 remains in line with GPT-6 Astra 43 and GPT-6.1 Sol 42 Key model details: ➤ Context Window: 1M tokens ➤ Multimodality: Text, image, video, and speech input, with text output ➤ Pricing: $4/$20 per 1M input/output tokens at standard pricing, currently discounted 50% to $2/$10 for at least one month. Cached input tokens receive a 95% discount $0.10 per 1M at discounted pricing , up from 90% on Gemini 3.8 Flash ➤ Long Decode Continuation: We tested Gemini 4 Argon with Long Decode Continuation, a new Gemini API feature that pauses long responses and resumes them across follow-up calls. This lets reasoning run up to 1M output tokens without request timeouts For further analysis, see https://artificialanalysis.ai/models/gemini-4-argon https://artificialanalysis.ai/models/gemini-4-argon Read the latest AA-AgentPerf-Local: Benchmarking local AI agents on laptops and workstations Our open-source tool for testing how fast agentic AI runs on laptops and workstations, with launch results for the DGX Spark, Ryzen AI Halo, MacBook Pro M5 Pro and RTX 5090 across four open-weights models September 29, 2026 GPT-6.1 Sol replaces GPT-6 Sol after just 7 days, with near-Astra intelligence GPT-6.1 Sol replaces GPT-6 Sol after just 7 days. It scores 1 point below GPT-6 Astra in the Intelligence Index at less than one quarter of the Cost per Task September 29, 2026 Announcing the Artificial Analysis Cyber Index Alliance The Artificial Analysis Cyber Index Alliance brings together industry partners to set a new standard for evaluating how AI models perform on enterprise cyber defense tasks. The Alliance launches alongside the Artificial Analysis Cyber Index, which combines three partner-contributed and open benchmarks to evaluate how well agents find and fix vulnerabilities.
