MAIN AI UPDATES / 17th September 2025

🤖 GPT-5 Codex gets agentic coding upgrades 🤖
OpenAI GPT-5 Codex dynamically adjusts compute time and cuts token usage significantly.

OpenAI upgraded GPT-5 Codex with agentic capabilities that dynamically adjust compute time based on task complexity, working from seconds to several hours on complex projects. The enhanced model outperforms the previous GPT-5 on SWE-bench Verified while cutting token usage by 94% for simple tasks and dedicating 2x reasoning time to complex problems. It includes built-in code review capabilities that can navigate entire codebases, representing a significant advancement in AI-powered software development. This upgrade demonstrates OpenAI's continued focus on specialized coding models for professional developers, potentially transforming how teams approach complex software development workflows.

💳 Google enables AI agents autonomous financial transactions 💳
Google's AP2 protocol enables AI agents to handle autonomous financial transactions.

Google launched an open-source payments protocol that enables AI agents to send and receive money on behalf of users autonomously. The AP2 protocol supports both traditional payment methods like credit cards and modern solutions like stablecoins, with backing from over 60 major financial partners including Coinbase, Mastercard, PayPal, and American Express. The protocol creates secure digital contracts called 'mandates' that verify user authorization before transactions, building on Google's April framework for agent-to-agent communication. This development addresses a critical infrastructure gap in AI agent capabilities, potentially enabling more sophisticated autonomous economic interactions.

🇺🇸 TikTok nears American ownership deal 🇺🇸
TikTok US reportedly close to becoming American-owned following national security negotiations.

TikTok US is reportedly close to becoming an American-owned entity following extended negotiations over national security concerns. President Trump has signaled that the US and China have reached a framework for a new ownership structure where a consortium including major players like Oracle, Andreessen Horowitz, and other American investors could own up to 80% of TikTok's US operations and assets. This potential deal would resolve the ongoing regulatory standoff that has threatened the platform's operations in the United States, while maintaining operational continuity for the popular social media app's American user base.
