How you store a streamed AI response decides what a client sees when the client joins partway through. A human agent taking over a support conversation, a refreshed browser, and a second device all need the response generated so far, and depending on how the response was stored, that late joiner gets the full response, fragments, or nothing. This article compares four common ways to store a streamed response, what each one gives a late joiner, and what each one costs your team.

You’ve probably encountered the online conversations about GitHub’s AI scaling challenges. A lot of the chatter is about how forgiving (or not) users should be to GitHub in light of inexorable traffic increases but also GitHub’s own decision-making. There is certainly irony in the fact that it was a swashbuckling GitHub, against the objections of many open source developers, that pressed Copilot on the industry.

In a release test I published in July, Katalon’s AI runner reported seven cases passed and four failed. I could open the steps, inspect their screenshots, and watch the browser session. The failed rows showed which expectations broke. The passed rows deserve the same scrutiny: what had the agent observed before it called each step passed? An AI test runner has to perform the action and judge the outcome. A false pass is a passed verdict when the expected behavior did not occur.

Your team has more changes to test, more environments to cover and less time to maintain regression suites. AI can help produce tests, but that introduces another workload: deciding whether those tests check the right behavior, whether a repair hides a defect and whether the evidence is enough to support a release. Agentic QA tools aim to take on more of that work, from planning and authoring to execution and failure investigation.
