Google opens Gemini 4 Argon to paying users, with API pricing from $2 per million input tokens

Google made Gemini 4 Argon, the frontier model it announced on September 30, generally available worldwide on October 13 (US time).

Developers and enterprises get it through the paid tier of the Gemini API. Consumers get it in the Gemini app and AI Mode in Search on the paid Google AI Pro and Ultra plans, while the agentic coding environment Google Antigravity is limited to Ultra subscribers.

The introductory API price is $2 per million input tokens and $10 per million output tokens, with cached input at 95% off. Ars Technica reports that the rate holds through November 30 and then rises to $4 and $20.

Google says Argon ranks first on the Vals Index, which measures work in finance, law, tax and coding. Inside Google, teams using it in Antigravity raised agentic code submissions by more than 35% and cut code rollbacks by nearly a third.

Google also published agent-safety results. On the Gray Swan indirect prompt injection benchmark, Argon held attack success to 0.7% across 15 adaptive attempts.

The Gemini app now connects to more than 40 apps, including Instacart and Shopify, so users can hand off tasks such as grocery orders and table bookings.

Character.AI files for Chapter 11, with Disney bidding $20 million to license some of its IP

Character.AI, the service that lets users chat with AI characters, filed for Chapter 11 bankruptcy protection in the US Bankruptcy Court for the District of Delaware.

According to TechCrunch, the company's court filing lists assets and liabilities each in the range of $50 million to $100 million. The filing says the high cost of building and growing AI entertainment, combined with potential litigation liabilities and regulatory engagement, left the company unable to generate enough cash to support the business in its present form.

Disney is the stalking horse bidder in the court-supervised sale. CNBC and Ars Technica report that the $20 million bid covers a non-exclusive perpetual license to certain Character.AI intellectual property, with transition services provided by former Character.AI employees who joined Disney along with former CEO Karandeep Anand.

CEO Colin Adams said the platform will keep running during the sale, which is expected to close in late November or early December. If no bid allows continued operations, the platform will be wound down.

Ars Technica notes that the company's privacy policy allows user information, including chat logs, to be transferred in a sale of company assets.

American Express publishes a framework that makes AI agents carry proof of purchase intent

American Express published Intent Intelligence, a framework for capturing and authenticating a customer's purchase intent before an AI agent completes a transaction, on October 13.

The customer's approved intent reaches the card issuer before the agent buys, and then serves as a control for the rest of the transaction. Amex released the framework publicly to push for a common industry approach, and offers it through its ACE Developer Kit.

It works in four steps. A Create Intent API records the customer's instructions and constraints, such as the merchant and a maximum budget, and the customer authenticates and signs off.

An Intent ID and a Proof of Intent Token are then issued. The agent uses the token to obtain a scoped digital payment credential that it presents at checkout in place of the actual card number.

The ID and token stay attached to the purchase for fraud checks, authorization decisions and dispute resolution. Amex's Hannah Bozian told TechCrunch that if a customer asks for white Nike sneakers and the agent tries to buy Adidas, Amex could stop the transaction.
