AI & Tech briefing · Friday, 23 October 2026
This period was dominated by distribution and trust rather than raw capability. OpenAI pushed its models into new channels, including Google Cloud, enterprise deployments and a wider ChatGPT ad footprint, while also pressing hard on cyber defense and access standards. Alongside this, agent security and identity moved from theory to product, with 1Password and Microsoft-linked research pointing to where the real constraints sit. For builders, the signal is that model access is becoming commoditized, and the durable advantage lies in the surrounding safeguards, workflows and trust.
