Alphabet Shares Gain After Launch of Competitively Priced Gemini 4 Argon AI

Shares of Alphabet Inc. (NASDAQ:GOOGL) rose approximately 2% in premarket trading Thursday following the launch of Google's new artificial intelligence model, Gemini 4 Argon. The company is positioning the model to compete aggressively on both performance and cost, particularly in the high-demand fields of software development and cybersecurity.

Competitive Pricing and Performance

Google has introduced Gemini 4 Argon with a pricing structure that significantly undercuts key competitors. According to an analysis by Jefferies, the model's costs are substantially lower than comparable offerings from rival AI firm Anthropic.

• Gemini 4 Argon: $2 per million input tokens and $10 per million output tokens.
• Claude Fable 5.1: $10 per million input tokens and $50 per million output tokens.
• Claude Opus 5.5: $4 per million input tokens and $20 per million output tokens.

On performance, Google stated that Argon achieved a record score of 77.9% on the DeepSWE v1.1 coding benchmark. Jefferies analysts noted that while it trails some models on other tests, it ranked first for coding on LLM Arena’s Text Arena. The model also features an increased output limit of 1 million tokens, a significant jump from the previous 64,000 and well above the 128,000-token limit for Anthropic's models, as cited by Jefferies.

Focus on Cybersecurity

A key focus for the new model is its advanced cybersecurity capabilities. Google claims Argon can autonomously identify, verify, and repair software vulnerabilities. In benchmark testing, it tied for the top score of 68% on the CWE-bench v1 test for vulnerability fixes, according to Jefferies.

Google is initially rolling out the model to a select group of trusted cybersecurity researchers, including the firm Wiz, with fewer of its standard safeguards to test its defensive potential. The company also highlighted Argon's lower success rate for prompt-injection attacks at 0.7%, compared to 1% for leading Claude models, suggesting enhanced security.

Market Impact and Analyst Outlook

The launch provided a boost to Alphabet's stock, which, according to Jefferies, had fallen 16% from its May 18 peak amid investor concerns that the company was lagging in the AI race. The brokerage, which maintains a "buy" rating and a $445 price target on the stock, views the launch as a positive step.

However, analysts at Jefferies cautioned that the model's strong benchmark results must be validated through real-world application. They noted that the performance of AI is increasingly dependent on the systems used to run and evaluate the models, not just the models themselves. Google plans to strengthen safeguards on Argon before a broader release to developers, businesses, and consumers.
