Türkiye's new advertising rules take effect on August 1
The Ministry of Trade's amendments to the Commercial Advertising and Unfair Commercial Practices Regulation take effect on August 1, 2026. Ads featuring AI-generated characters that cannot be distinguished from a real person must say so, influencer posts must carry an advertisement label, discount claims must reference the lowest price of the previous ten days, and environmental claims must be documented.
Anthropic releases Claude Opus 5 for long-running agents
Anthropic released Claude Opus 5 on July 24 and described it as a step change for the Opus tier that powers long-running agents. The company says it delivers the frontier intelligence of its top model at half the price, that the model verifies its own output and iterates until it succeeds, and that it leads on coding and knowledge-work evaluations.
ChatGPT Ads opens conversion bidding and bulk management
OpenAI added conversion-optimized cost per click, location exclusions, average daily budgets spread across seven days, intraday pacing and bulk campaign management to ChatGPT Ads. Mobile measurement partnerships bring install and in-app event attribution across seven markets, with Türkiye not on the list for now.
The agenda moves fast, the system stays calm.
Let's talk about what these changes mean for your business and clarify which step fits you.
