New autonomous deployment agent eliminates the last mile between AI-generated code and production-ready software.

SAN FRANCISCO, June 10, 2026 /PRNewswire/ — Opsera, the leader in AI-powered software delivery, today announced VIBEshift, a new autonomous deployment agent that turns AI-generated applications into production-ready software with a single command. VIBEshift lets developers, AI builders and enterprise teams eliminate the last mile between rapidly generated prototypes and secure, deployable applications running in production environments.

Generative AI has dramatically accelerated software creation, with tools like Claude, Cursor and Lovable enabling the creation of functional applications with unprecedented speed. Yet moving AI-generated applications into production remains complex. Teams still face manual processes to set up infrastructure, deployment pipelines, security controls and operational oversight.

VIBEshift operates directly within the developer workflow to autonomously analyze applications, provision infrastructure, and deploy production-ready code. It addresses the need for developers to move from prototype to production without waiting on operational teams.

“AI has forever changed how software is created, but deployment remains a major bottleneck in software delivery,” said Kumar Chivukula, co-founder and CEO of Opsera. “Now, developers can generate working applications in minutes and transform them into secure, production-ready software without days of manual effort and specialized expertise. By eliminating that last mile to production, organizations can move from idea to production with Vibe-style simplicity and speed.”

VIBEshift executes deployments autonomously, from provisioning infrastructure and configuring authentication to validating deployments and performing operational checks. It manages CI/CD tasks traditionally handled by multiple teams and tools.

Key VIBEshift capabilities include:

Autonomous Deployment: Automatically provisions infrastructure and deploys applications to production-grade cloud environments directly from the IDE with a single command.Built-In Security and Governance: Applies security controls, authentication and deployment policies throughout the deployment process.Self-Healing Operations: Automatically identifies and remediates deployment failures to improve reliability.Full Auditability: Maintains detailed deployment records and operational logs for governance and compliance requirements.Deterministic Execution: Delivers consistent, repeatable deployment outcomes through policy-driven automation.

Interwell Health Delivers Strong Quality Scores and Shared Savings in CMS Value-Based Kidney Care Model

Published

Interwell achieved top quality scores and sustained savings growth over the first three years of the Kidney Care Choices Model

BAD HOMBURG, Germany, June 10, 2026 /PRNewswire/ — Interwell Health, the value-based care operating segment of Fresenius Medical Care, has released new results showcasing exceptional performance in the U.S. Center for Medicare & Medicaid Innovation’s (CMMI) Kidney Care Choices (KCC) Model1. As the largest participant in the Comprehensive Kidney Care Contracting (CKCC) program option, Interwell delivered $273 million in shared savings2 to the government program and consistently achieved top quality scores (88% average, 9 points higher than non-Interwell CKCC participants) over the first three years of the program, solidifying its leadership in value-based kidney care.

The Centers for Medicare & Medicaid Services (CMS) recently released new data that highlights Interwell’s strong results in the CKCC program:

Industry-leading quality: Largest share of high performer pool (44% of three-year total), with the most high performers and most perfect scores in 2024Outstanding financial results: 43% higher three-year average adjusted gross savings rate compared to non-Interwell Kidney Care Entities (KCEs)Scalable growth: Increased gross savings 1 percentage point year over year while serving the largest patient population (in 2024, Interwell served 59,520 patients across 23 KCEs)

“Our leadership in the CKCC program further validates that Interwell Health is setting the standard for kidney care,” said Tommy O’Connor, CEO of Interwell Health. “Our consistent quality results and ability to improve patient outcomes at scale demonstrate that value-based care transforms lives and delivers significant savings to the healthcare system. When you combine a compassionate network of patient-centered nephrologists with Interwell’s hands-on care model and advanced technology, patients win.”

Year-over-year improvement and industry leadership

CMMI developed the KCC Model to test strategies that increase care coordination for Medicare patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD) while improving outcomes and reducing total cost of care. Since the program’s inception, Interwell has consistently delivered measurable improvements in quality metrics including:

Higher rates of optimal dialysis starts, which measures the percent of patients who transition from late-stage CKD to ESRD care by starting dialysis at home, starting dialysis in-center with permanent dialysis access, or receiving a preemptive kidney transplantImproved Patient Activation Measure (PAM) scores, which measure a patient’s knowledge and confidence in managing their healthIncreased use of home-based therapies, which measures the percent of patients who start dialysis at home instead of in-center

Additionally, Interwell grew its gross shared savings rate 71% over three years (3.6% in 2024 from 2.1% in 2022), reflecting the growing financial success of the CKCC Model as it matures.

Interwell supports nephrology practices in the CKCC with resources including embedded renal care coordinators (RCCs), clinical documentation support, and advanced analytics. “Without an RCC I don’t know how this program would work, because the RCCs do so much in terms of increasing optimal starts and engaging family members,” said Dr. William McElhaugh, a nephrologist at Kidney Care Specialists. “We also use Acumen®, Interwell’s electronic health record system, which allows us to see patients’ medical histories to ensure that they are risk stratified properly, which you need to do to be successful in a value-based program.” Kidney Care Specialists is part of the Interwell Philadelphia KCE, one of only five KCEs to earn a perfect score in the 2024 program year.

Interwell’s ongoing success in value-based kidney care is powered by its robust network of more than 2,300 nephrologist partners, comprehensive care model, proprietary Epic® Connect EHR platform Interwell Acumen™, and tight alignment with Fresenius Medical Care. Together, these capabilities enable a sustainable approach to kidney disease management that reduces costs and improves outcomes across the care continuum.
