Anthropic extended free access to Claude Fable 5 for paid subscribers through July 19, 2026, instead of switching to pay-per-use billing today. Subscribers can allocate up to 50 percent of their weekly usage limit to Fable 5 at no additional cost during this period. The extension reflects competitive pressure from OpenAI's GPT-5.6 Sol and lower-cost alternatives, as Fable 5 consumes usage quota faster than other Claude models.

Anthropic accused Alibaba of using 25,000 fraudulent accounts to extract capabilities from Claude through unauthorized API access. The alleged extraction campaign used coordinated accounts, proxy services, and repetitive prompts to harvest reasoning, tool-use, and reinforcement-learning data that could be used to train competing models. The distinction matters because legitimate distillation of intentionally released models should remain permitted, while covert extraction through fraud should face enforcement at the access layer rather than through restrictions on open AI.

Researchers have identified model distillation—training one AI system on outputs from another—as a threat to the business model of frontier AI companies, with Chinese competitors using the technique to quickly develop cheaper alternatives to expensive US models. Chinese companies have built networks of overseas "transfer stations" charging as little as 10% of official prices to bypass access restrictions, allowing them to collect vast datasets for training their own systems. If distillation becomes widespread, it could erode the returns on the billions spent by OpenAI, Anthropic, and Google on developing leading models, with some researchers warning that restrictions may simply push developers toward open-source alternatives instead.

Anthropic and OpenAI accused Chinese companies including Alibaba and DeepSeek of using a technique called "distillation" to copy their AI models without permission and produce cheaper alternatives. Anthropic reported that Alibaba generated 28.8 million outputs from Claude using nearly 25,000 fraudulent accounts between April and June 2024. The theft allows Chinese AI firms to narrow the technology gap from an estimated 18-plus months behind to 6-9 months, enabling them to undercut US companies on price and potentially erode American AI leadership.

Satya Nadella accused AI labs like Anthropic of hypocrisy for using public data to train their models while prohibiting other companies from distilling knowledge from those same models. Anthropic complained in February that Alibaba conducted "the largest known distillation attack" on it, yet Nadella argues such complaints ignore that model makers themselves relied on unrestricted access to public data. Nadella called for enterprises to build their own AI infrastructure and maintain strict boundaries over their proprietary data rather than depend on third-party model vendors.

Codex usage grew from 2 million users in March to 7 million users by mid-July, representing approximately 10x growth over six months. The service added 1 million new users in roughly a single day following the July 9 launch of GPT 5.6 Sol, reaching 6 million users within 48 hours. Codex's growth trajectory now appears to match or exceed Claude Code's expansion, shifting competitive focus toward which coding platform maintains momentum in user adoption.
