• Google says Argon is rolling out to a set of trusted cyber defenders through its Fairwind Program, and will be released to them without cyber guardrails.
• Google says Argon launches at an introductory price of $2 per million input tokens and $10 per million output tokens, and its output limit rises to 1M tokens from 64K.
• Google reports 77.9% on DeepSWE v1.1 and 91.7% on LVBench, calling both state of the art, and says Argon ranks first on Zapier’s AutomationBench at 51.3%.

Google announced Gemini 4 Argon on 30 September 2026. It is rolling out first to a set of trusted cyber defenders through the Fairwind Program. Google says it will make Argon available to developers, enterprises and consumers as soon as possible, after a phased expansion. Argon will launch at an introductory price of $2 per million input tokens and $10 per million output tokens. Cached input tokens are priced at 95% off the input token price. Google raised the output token limit to 1M tokens, up from 64K. Google reports 77.9% on DeepSWE v1.1, 51.3% on AutomationBench and 91.7% on LVBench. For trusted defenders and its own teams, Google will release Argon without cyber guardrails.

• On ExploitBench, Anthropic reports GLM-5.3 developed end-to-end exploits in 50 of 410 attempts and Claude Mythos Preview in 56 of 410, in Anthropic’s own test.
• Anthropic says in its simulated tests GLM-5.3 engaged with overtly malicious requests to attack critical systems 64% with a deceptive prompt, 92% with prefilled thinking and 100% when abliterated.
• Anthropic says NIST’s CAISI found GLM-5.3 "the most cyber-capable open-weight model released to date" in an assessment published on 17 September.

Anthropic’s Frontier Red Team published an analysis of Zhipu AI’s GLM-5.3 on 29 September 2026. On ExploitBench, GLM-5.3 developed end-to-end exploits in 50 of 410 attempts, and Claude Mythos Preview did so in 56 of 410. On Anthropic’s internal Binary Exploitation benchmark, GLM-5.3 achieved full control-flow hijacks in 4% of trials and Claude Mythos Preview in 6%. Anthropic says attackers can bypass GLM-5.3’s safeguards between 64% and 100% of the time with simple techniques in its simulated tests, and that these did not succeed against safeguarded Claude models. A researcher using the smaller GLM-5.3-Flash built an exploit chain for a Chrome flaw (CVE-2026-11645) at an API cost Anthropic puts at $20.40. Anthropic also says NIST’s CAISI published its own assessment of GLM-5.3 on 17 September and found it the most cyber-capable open-weight model released to date.
