Google’s new top-tier Artificial Intelligence (AI) model Gemini 4 Argon has been launched on Wednesday with initial limited access to a vetted group of cybersecurity experts over concerns about potential misuse by hackers.
Alphabet’s Google said that Argon will anchor its Gemini 4 generation of models as the company seeks to compete with AI models from Anthropic and OpenAI.
Explaining the restricted release, Google chief AI architect Koray Kavukcuoglu stated that the company will take a phased approach to releasing the model because of its capabilities. “Safely releasing frontier capabilities at this level requires a phased approach,” Kavukcuoglu wrote in a blog post announcing Argon.
A Google spokesperson said that Argon is larger than the company’s previous line of advanced Pro models and described it as the company’s most capable model so far for complex workloads.
“It’s our most performant model yet built for complex workloads, and we see it comparable to frontier models like (OpenAI’s) Astra and (Anthropic’s) Opus on key coding and cyber benchmarks,” the spokesperson said.
Google also said that it will provide Argon to selected cybersecurity partners and will also participate in the Trump administration’s voluntary process for pre-release model access. The company has not given a timeline for when it will make the model available to the public.
According to Google’s press release, Argon recorded higher results than OpenAI’s Astra and Anthropic’s Opus on several industry benchmarks based on the company’s reported performance.
However, the model remained behind its competitors on some other measures, including two of the four coding-related benchmarks included by Google.
The announcement also marks a change in Google’s plans for its previous model. The company will no longer release Gemini 3.5 Pro, which CEO Sundar Pichai had originally said will launch in June.
Google’s delays in releasing its AI models came as the company made changes to its DeepMind AI lab. Its founder and CEO Demis Hassabis stepped aside, while several leaders involved in the Gemini model also left the company.
The delays have given Anthropic and OpenAI more time to release updates to their top models and continue developing their AI systems.
Pichai pushed back in July against the view that Google was losing ground in the AI race.
In recent months, however, Google has shifted its messaging around Gemini, moving from emphasis on the model’s capabilities to highlighting its cost advantage compared with competing models.
