Notes

What changed in AI, for product people.

A running record, newest first. Each note says what happened, names its source, and ends with the point for people who run products. Live sessions appear in the same stream as dated events.

  1. The Agentic AI Foundation now holds ten projects, from three

    The Agentic AI Foundation took in four more projects: Agent Skills from Anthropic, Open Responses from OpenAI, OpenEnv from Hugging Face and OpenSandbox from Alibaba. It now holds ten projects, up from three.

    For product people: Build an agent skill once and expect it to work across assistants. Standards are how a team's prompts and skills become an asset rather than a lock-in.

  2. OpenAI models come to Google Cloud, next to a managed Claude

    OpenAI's models are coming to Google Cloud, and Anthropic now offers a way to run Claude on Google Cloud that Anthropic itself manages.

    For product people: On Google Cloud you can now try both without a new contract. Choose the Claude option by who handles your data, not by the logo.

  3. Decision models: an answer without the essay

    Three decision models arrived in one day: OpenAI's Decisions API became generally available, Liquid AI released d1 and Ollama released d3. They answer a question with a choice rather than a paragraph.

    For product people: A surprising share of the steps in a workflow are choices, not prose. Those steps suit a decision model: faster, cheaper and easier to test.

  4. AI found two critical PHP flaws before anyone else did

    Two critical vulnerabilities in PHP were found with AI under OpenAI's Patch the Planet programme, and fixes shipped on 21 October. Security tools from AWS, GitHub and Anthropic now go past finding flaws to proposing the fix.

    For product people: If anything you run uses PHP, apply the fixes. More broadly, the time between a flaw being found and being exploited is shrinking, so patch speed is now a product metric.

  5. Free-to-download models catch up: three releases in three days

    Three free-to-download models in three days: Meta's Muse Spark Open on 15 October, Reflection AI's Beam on 16 October under the Apache 2.0 licence, and DeepSeek V4.1 Flash on 17 October under the MIT licence. On Vercel's AI Gateway, open models handled more than seven in ten tokens in September.

    For product people: Open models now handle most everyday jobs. Before you assume they are cheaper, measure the cost of the finished job, as the test above did.

  6. Live session 1: one hour on Google Meet, by invitation

    For product managers, project managers and engineers: how one person and a team of agents ship software, what a harness is and why the agentic SDLC needs one, and what product managers own when agents do the tasks. Attendees took away templates for an intent file and a skill, and a checklist to start on Monday.
