Four Major AI Launches in One Day

01 Oct 2025

Big day in AI: four major launches landed the same Monday. OpenAI rolled out "Instant Checkout" so U.S. ChatGPT users can discover and buy products inside conversations (Etsy now, Shopify soon) using Stripe — a potential move toward turning ChatGPT into a massive e-commerce channel (the newsletter cites ~700M weekly users).

Anthropic unveiled Claude Sonnet 4.5, a model the newsletter says sets new records on coding benchmarks and can sustain complex tasks “for over 30 hours.” Anthropic also shipped developer tools: Checkpoints to save/rewind progress in Claude Code, a native VS Code extension, file-creation features, and interactive experiences (e.g., “Imagine with Claude”).

Microsoft expanded 365 Copilot with an “Agent Mode” (called a “vibeworker” in the piece) that delegates entire projects — for example, creating sheets and charts and validating work in Excel — and integrates models like Claude Sonnet 4.5 in Copilot Studio.

Smaller labs kept up the pace: DeepSeek announced a more efficient model (DeepSeek‑V3.2‑Exp) that focuses on relevant parts of long documents and conversations to cut API costs (the newsletter mentions potential ~50% savings). The overall takeaway: product teams and labs flooded releases in one day, accelerating AI tool availability across search, coding, agents, and commerce.
