    <summary>An agent runtime executes, constrains, observes and improves. Kortix, the open-source AI Operating System, walks through the mechanism behind each job.</summary>
    <content type="text">An agent runtime is the layer that runs agent work: it gives a task a machine, decides what the agent may touch, records what happened, and feeds the result into the next run. Most products ship the first job and stop. Kortix is the open-source AI Operating System.</content>

    <summary>Agent runtime cost is a rate multiplied by a unit, and the unit varies. Kortix, the open-source AI Operating System, compares four vendors' billing.</summary>
    <content type="text">Agent runtime cost comes down to two numbers: the rate a vendor charges and how long it bills a session. Four runtimes price the same hour differently. Kortix is the open-source AI Operating System, and the paid plan is credits: 25 tiers from $50 a month (5,000 credits) to $50,000 a month (5,000,000 credits), at 100 credits per dollar.</content>

    <summary>How Kortix, the open-source AI Operating System, compares with AWS Bedrock AgentCore, Cloudflare Agents and Agyn on the record each run leaves.</summary>
    <content type="text">Choosing an agent runtime comes down to three questions: what the session runs on, what it leaves behind, and who approves the change. Four runtimes share a table, eight get a section each, and the argument lands on Kortix, the open-source AI Operating System, where the record stays in a repository you own.</content>
