The agentic launches that stayed with me final week had nothing to do with how succesful a mannequin is. They had been about attain. AWS Step Capabilities, which already orchestrates over 220 AWS providers, can now be handed to an agent as a software, so workflows groups already belief grew to become callable with out a rewrite. In the identical week, the AI weblog printed how one engagement platform uncovered roughly 400 inside API operations the identical manner. Neither story includes rebuilding something, solely describing what exists and letting the agent discover it.
The opposite thread was price. OpenAI’s latest Terra mannequin reached Amazon Bedrock priced nicely under the mannequin beside it, and two post-quantum launches landed for a deadline no person can placed on a calendar but. Now, let’s get into this week’s AWS information…
Headlines
OpenAI GPT-6.1 Terra is now typically obtainable on Amazon Bedrock, and what pursuits me is the place it sits quite than what it tops. Terra is the everyday-workload line of the GPT-6 household. In OpenAI’s Brokers’ Final Examination analysis it scored 15 share factors increased than GPT-5.6 Terra, carried out on par with GPT-6 Astra, and accomplished duties greater than thrice quicker than each. These are OpenAI’s figures, not an unbiased take a look at. The value is what I’d verify first: enter and output tokens are at the very least 50% decrease than GPT-6.1 Sol and GPT-5.6 Terra. It takes as much as 1 million enter tokens with textual content and picture enter, and you’ll attain it from the Bedrock APIs or ChatGPT Work and Codex.
AWS Step Capabilities workflows at the moment are obtainable as AI agent instruments by Amazon Bedrock AgentCore Gateway, which connects brokers to instruments over the Mannequin Context Protocol (MCP). The division of labor is the concept: the agent decides when to run a workflow and what enter to go; Step Capabilities runs every step precisely as you outlined it. A assist agent can set off a refund, and the eligibility verify, the supervisor approval, and the credit score nonetheless occur in that order each time, as a result of the ordering was by no means the mannequin’s to improvise. Your present Customary and Specific workflows qualify as connector targets, and brokers may also lookup runs. It’s obtainable in all Areas the place AgentCore Gateway is, at customary charges.
Final week’s launches
Listed here are some launches and updates from this previous week that caught my consideration:
AWS Key Administration Service now helps ML-KEM for post-quantum key encapsulation – Now you can set up a shared secret with a post-quantum algorithm utilizing AWS KMS keys, with non-public keys in FIPS 140-3 Stage 3 validated HSMs. All three NIST FIPS 203 parameter units are supported by Encapsulate, which produces a random 32-byte shared secret and its ciphertext, and Decapsulate, which recovers it. The risk is harvest now, decrypt later: an adversary data immediately’s key trade and recovers the key as soon as quantum computer systems are highly effective sufficient. It’s obtainable in all places KMS runs besides the Center East (UAE and Bahrain) and China Areas. Amazon Aurora PostgreSQL added post-quantum TLS key trade the identical week, on variations 18 and better.
AWS IAM Identification Heart now helps cross-Area trusted identification propagation – Now you can carry a consumer’s identification with their request to AWS providers in one other Area. This removes a real architectural constraint: trusted identification propagation used to require each service accessing that identification to sit down in the identical Area, which left two unappealing choices, broad IAM roles that can’t distinguish particular person customers, or consolidating all of your providers right into a single Area. Now the identification travels with the request robotically, so that you grant entry by consumer and group membership and audit who accessed what. It’s obtainable at no further price in all places IAM Identification Heart runs.
Amazon ECS now helps GPU sharing with NVIDIA Multi-Course of Service (MPS) – Now you can run a number of Amazon ECS duties concurrently on a single NVIDIA GPU, the sensible reply to work that solely ever makes use of a fraction of 1, like small-model inference and multi-model serving. You declare the GPU reminiscence every container wants and may optionally cap its share of GPU compute, and ECS locations duties on GPUs with obtainable capability as your providers scale, with no code modifications. It really works on ECS Managed Situations and ECS on Amazon EC2, and on Managed Situations it watches the MPS management daemon and replaces the occasion if it turns unhealthy. It’s obtainable in all business and AWS GovCloud (US) Areas.
AWS Lambda helps Seekable OCI (SOCI) lazy loading for Lambda Managed Situations – Now you can have AWS Lambda fetch solely the recordsdata wanted at every stage of startup as an alternative of pulling an entire container picture first, which AWS places at as much as 70% off container startup time. You create a SOCI index, push it to Amazon ECR, level the picture URI on the listed tag, and Lambda detects it robotically. The method additionally reached Amazon SageMaker AI coaching and processing jobs, with benchmarks: lazy loading held at 3 to 11 seconds no matter picture measurement, towards a median 3 minutes 42 seconds for a 13.2 GB picture, a variety they report as 8x to 46x.
Amazon EKS Auto Mode now helps Kubernetes Gateway API – Now you can declare how site visitors reaches your purposes with Gateway and HTTPRoute assets on Amazon EKS with out putting in a separate controller, and EKS Auto Mode provisions and manages the underlying AWS load balancing infrastructure. You get HTTP and gRPC routing, cross-namespace routing, weighted site visitors splitting, header-based routing, and automated TLS certificates discovery by AWS Certificates Supervisor. Current Ingress workloads preserve working alongside them, so that is additive quite than a migration. Gateway API assist is included with EKS Auto Mode; customary load balancing expenses apply.

Different AWS information
Listed here are some further posts and assets that you simply would possibly discover attention-grabbing:
How Nubank automated catastrophe restoration with the AWS DevOps Agent – Nubank serves greater than 140 million prospects throughout Brazil, Mexico, and Colombia, and classifies over 300 enterprise flows as essential, every examined on a regulator’s schedule. Nubank studies that handing proof assortment and report writing to the AWS DevOps Agent reduce a take a look at cycle from about 4.3 hours to roughly 40 minutes, and quadrupled stream protection in 2026 to greater than 160. One execution terminated greater than 900 EKS cases beneath artificial site visitors with AWS Fault Injection Service, producing the proof its regulator wanted.
How MoEngage turned over 400 APIs into agent instruments with AgentCore Gateway – Roughly 400 inside REST API operations, constructed by 25 groups, sitting in non-public VPCs throughout seven Areas, with tenant identification that might by no means develop into a parameter the mannequin will get to set. MoEngage estimates the managed path saved about six months of platform engineering. The element value stealing: a full software itemizing would have crossed 20,000 tokens per connection, so brokers seek for instruments by describing a activity as an alternative of receiving the catalog.
Decreasing petabyte-scale S3 storage prices with evidence-based lifecycle guidelines – The onerous half isn’t deciding to behave, it’s understanding which knowledge has gone chilly and the place it may possibly safely stay. This makes use of S3 Storage Lens teams and Storage Class Evaluation to show entry patterns earlier than transferring something. Within the engagement described, 5.8 PB of logs in Amazon S3 Customary at roughly $241,000 per thirty days confirmed an entry ratio under 0.1% previous 90 days, and a 90-day transition to Glacier Immediate Retrieval reduce the invoice by roughly 70%, a determine the creator ties to that workload.
