Stripe has developed a transformer-based payments foundation model, analogous to large language models, to move beyond the limitations of traditional machine learning models that rely on discrete features. By training on billions of transactions, this self-supervised network learns dense, general-purpose embeddings for each transaction, capturing complex relationships and subtle patterns. These rich embeddings have demonstrated significant success, such as improving real-time card-testing attack detection for large users from 59% to 97%. The model’s ability to distill transaction signals into versatile embeddings allows for better identification of nuanced, adversarial behavior and can be applied across various payment-related tasks like disputes and authorizations, suggesting that payments possess underlying semantic meaning and complex sequential dependencies.

Visa Intelligent Commerce (VIC) is a new API‑suite and partner program launched on 30 April 2025 that lets autonomous AI agents not only recommend but pay for goods and services. It wraps Visa’s tokenization, authentication and fraud‑detection rails into five modular services—AI‑Ready Cards, Authentication, Payment Instructions, Personalization and Signals—so any agent built by partners such as OpenAI, Microsoft, Anthropic, Stripe, Samsung and others can transact safely inside preset spend limits. Early pilots begin this year; global rollout is expected in 2026.

Alibaba’s Qwen crew has unleashed Qwen 3, an Apache-2.0 stack from a svelte 0.6 B up to a 235 B-parameter MoE colossus (only 22 B active) that humbles much larger rivals. A new “hybrid-thinking” switch lets it waffle through chain-of-thought when problems get knottier, or snap out terse replies when latency is tighter than a Monty Python cheese shop. Fed a gluttonous 36 T tokens in 119 languages, sporting 128 K context, sharper coding and agent skills (MCP + Qwen-Agent), and plug-and-play support for vLLM, Ollama, SGLang and friends, the dense models outclass Qwen 2.5 at half the size while MoE variants trim inference bills by ~90 %. Translation: deeper reasoning, faster answers, and your finance chief won’t need to resort to the comfy chair.

OpenAI is launching a shopping experience within ChatGPT, featuring product recommendations and buy buttons. The recommendations, based on user preferences and web reviews, aim to provide a more personalized and conversational shopping experience compared to Google Shopping. OpenAI is exploring various affiliate revenue models to support online publishers while prioritizing high-quality recommendations. ChatGPT users are running over a billion web searches per week, and that people are using the tool to research a wide breadth of shopping categories, like beauty, home goods, and electronics
