ChatGPT asks users with a banner to start advertising
OpenAI shows a banner in ChatGPT with which you can create your first advertisement in a few minutes: you enter your website URL and Ads Manager suggests an advertisement based on it, which you then adjust. Dutch businesses have been able to advertise themselves since 31 August; the minimum daily budget is €15 and you pay per 1,000 impressions, per click or per conversion. Only Free and Go users see advertisements; Plus, Pro, Business, Enterprise and Edu remain ad-free, as do users under 18.
What does this mean? For marketers and SMEs, ChatGPT is now an advertising channel you can test without an agency; if you use the free version for work, you will get advertisements alongside your answers.
Cloudflare Auto Router picks a cheaper model per request
Cloudflare has put the Auto Router in public beta within AI Gateway. Set your model to cloudflare/auto, and a classifier assesses each request by task type and complexity, then chooses a model that is good enough at the lowest token price. According to Cloudflare, this saves up to 30% compared with using frontier models such as GPT-6 Sol and Claude Opus 5.5 alone. In its own test, the router achieved a 86.6% success rate, against 96.6% for Opus alone. The router is free for as long as it remains in beta.
What does this mean? If you build AI applications via an API, you can save costs with automatic model selection, but first test whether the lower success rate is acceptable for your tasks.
Anthropic introduces Mods to customise Claude Code
With Mods, you write small JavaScript or TypeScript functions that respond to events in Claude Code, such as prompts, tool calls and interface rendering. This lets you add your own panels and commands or intercept tool calls. Mods work in the CLI and the desktop app, and partly in the VS Code extension. They run without a sandbox with your user permissions, and organisations can determine which Mods may load.
What does this mean? Development teams can tailor Claude Code to their own ways of working, but only install Mods from trusted sources and, as an organisation, record which ones are permitted.
