Amazon previews 3 AI agents, including ‘Kiro’ that can code on its own for days

Amazon Internet Companies on Tuesday introduced three new AI brokers it calls “frontier brokers,” together with one designed to learn the way you wish to work after which function by itself for days.

Every of those brokers deal with completely different duties similar to writing code, safety processes like code opinions, and automating DevOps duties similar to stopping incidents when pushing new code dwell. Preview variations of the brokers can be found now.

Maybe the most important and most attention-grabbing declare by AWS is its promise that the frontier agent known as “Kiro autonomous agent” can work by itself for days at a time.

Kiro is a software program coding agent based mostly on AWS’s present AI coding software Kiro, which was introduced in July. Whereas that present software could possibly be used for vibe coding (which is absolutely simply prototyping), it was supposed to supply operational code, or software program that might be pushed dwell. To make dependable code, the AI should observe an organization’s software-coding specs. Kiro does that by way of an idea known as “spec-driven growth.”

As Kiro codes, it has the human instruct, verify, or appropriate its assumptions, thereby creating specs. The Kiro autonomous agent watches how the staff works in numerous instruments by scanning present code, amongst different coaching means. After which, AWS says, it will possibly work independently.

“You merely assign a fancy job from the backlog and it independently figures out easy methods to get that work accomplished,” AWS CEO Matt Garman promised when introducing the brand new product throughout his keynote at AWS re:Invent on Tuesday.

“It truly learns the way you wish to work, and it continues to deepen its understanding of your code and your merchandise and the requirements that your staff follows over time,” he stated.

Amazon says Kiro maintains “persistent context throughout periods.” In different phrases, it doesn’t run out of reminiscence and neglect what it was speculated to do. It might due to this fact be handed duties and work by itself for hours or days, Amazon guarantees, with minimal human intervention.

Garman described a job like updating a little bit of important code utilized by 15 bits of company software program. As an alternative of assigning and verifying every replace, Kiro may be assigned to repair all 15 in a single immediate.

To finish the automation of coding duties, the cloud supplier developed AWS Safety Agent, an agent that works independently to establish safety issues as code is written, exams it after the very fact, after which affords advised fixes. The DevOps Agent rounds out the trio, robotically testing the brand new code for efficiency points, or compatibility with different software program, {hardware}, or cloud settings.

To make certain, Amazon’s brokers aren’t the primary to assert lengthy work home windows. As an illustration OpenAI stated final month that GPT‑5.1-Codex-Max, its agentic coding mannequin, is designed for lengthy runs, too, as much as 24 hours.

It’s additionally not completely clear that the most important hurdle to agentic adoption is the context window (aka the flexibility to work constantly with out stalling out). LLMs nonetheless have hallucination and accuracy points that flip builders into “babysitters,” they are saying. So builders typically need to assign quick duties and confirm rapidly earlier than shifting on.

Nonetheless, earlier than brokers can turn out to be like co-workers, context home windows should develop greater. Amazon’s tech is one other huge step in that path.
