Missing figures stay unavailable. Forward P/E requires a dated source. Annual revenue, revenue growth, net income and margin come from each company's own 10-K, in US dollars, and each row shows that fiscal year. Revenue growth compares the fiscal year with the prior year stated in the same 10-K. Net income is the full year amount attributable to the company, or available to common stockholders where the filing states only that, or consolidated net income. Each row names its basis. Trailing P/E reads "Not meaningful" when the dated trailing diluted EPS is a loss or zero. An operating margin appears only when the filing states both the operating income and the revenue for the same year.

Sources: SEC filings, Gloria daily closes and CoinGecko. Oldest record refresh: Oct 27, 2026, 9:41 PM EDT. Refresh is not a price or filing date. Each row shows its price date and its annual fiscal period. Peers use industry code and company size, or editorial selection. Market cap multiplies that row price by the company share total the latest SEC filing states for every share class together. Trailing P/E divides it by trailing diluted earnings from SEC filings. Rolled earnings per share are approximate because share counts can change between periods. Both appear only when the SEC data carries its date, so they are estimates at one price date, not synchronized filing valuations. Not investment advice.

Quoted token and share units can have different rights, multipliers and dividend treatment. This is not an executable premium or arbitrage signal.

Alphabet CEO Sundar Pichai has a new AI model to show off. Most people will have to wait in line to use it.

Pichai announced that Gemini 4 Carbon, Google’s latest model, will first roll out to cybersecurity partners. The model is built with a heavy emphasis on finding software flaws, testing whether they can be exploited, and fixing them.

What Carbon is built to do

The launch came on October 28, 2026. Gemini 4 Carbon targets three core security tasks: vulnerability discovery, exploitation validation, and software patching. It also comes with strong coding capabilities.

The benchmark numbers back up the pitch. Carbon scored 59 on version 5.0 of the Artificial Analysis Intelligence Index, the top score on that ranking.

On security-specific tests, the results looked like this:

  • SEC-bench (vulnerability finding): 88.2%
  • ExploitGym (exploitation): 54.8%
  • CWE-bench (patching): 71.0%

All three figures mark a significant improvement over Gemini 4 Argon, the model Carbon replaces. On vulnerability discovery specifically, Carbon’s success rate more than doubles Argon’s.

Pricing, meanwhile, stays put. Carbon costs $2 per million input tokens and $10 per million output tokens, the same rates Google charges for Argon.

Two weeks, two models

Carbon arrived just two weeks after Gemini 4 Argon. The quick turnaround reflects Google’s use of AI-assisted model development.

Initial access begins this week for trusted cybersecurity defenders through Google’s Fairwind Program. The program exists to manage a responsible rollout and keep testing safe.

Pichai stressed the importance of rolling Carbon out responsibly, with strengthened safeguards in place. Google plans a phased expansion that would bring the model to more developers, businesses, and eventually consumers.

Investors seemed to like what they heard. Alphabet shares rose approximately 1.5% after the announcement.

Why the cautious rollout matters

The gated launch makes more sense once you look at what Carbon is good at. A tool that excels at finding vulnerabilities and confirming they can be exploited is useful to defenders. The same skills would be useful to attackers.

Starting with vetted security teams gives Google a chance to see how the model performs in real defensive work. The Fairwind Program effectively functions as a controlled test environment with real stakes.

The exploitation score is the number worth watching. At 54.8% on ExploitGym, Carbon is the weakest of the three security benchmarks by a wide margin.

What this means

Gemini 4 Carbon is positioned against OpenAI’s GPT-6 Astra and Anthropic’s Claude Opus 5.5.

By leading with security, Google is staking a claim on a specific, high-value niche rather than just general-purpose intelligence. Holding pricing flat while improving performance also puts pressure on rivals.

Google has not tied the broader expansion to specific dates. Developers and businesses eager to try Carbon will be watching for the next stage of access.
