OpenCost 1.121.0: First-of-a-Kind Kubernetes Inference Cost Tracking

Your GPU bill is rising. Your models are serving billions of tokens. Yet one question remains unanswered: what does each token actually cost?

On March 5, 2026, we’re updating the OpenCost community meeting schedule so that contributors and users in the Americas, Europe/Middle East/Asia (EMEA) , and Asia-Pacific (APAC) can all join at a reasonable time. Here’s what’s changing and how to join.
The OpenCost project has had a fruitful year in terms of releases, our wonderful mentees and contributors, and fun gatherings at KubeCons.

This project was initiated as part of the LFX Fall 2025 mentorship program at OpenCost and development is ongoing.
OpenCost is evolving. As Kubernetes environments grow in complexity with pods being recreated, names being reused, and resources constantly shifting, the need for a more robust, scalable data model has become clear. Today, we're excited to introduce KubeModel, the foundation of OpenCost's Data Model 2.0, designed to bring precision, efficiency, and reliability to Kubernetes cost tracking.
The OpenCost team will be at KubeCon Atlanta 2025 with talks and activities November 10-13, 2025!


The future of Kubernetes cost management is here, and it's powered by AI. We're excited to announce that OpenCost now includes a built-in Model Context Protocol (MCP) server that enables AI agents to directly access and analyze your Kubernetes cost data. This groundbreaking integration brings intelligent automation to cost optimization, making it easier than ever to understand, predict, and optimize your cloud spending.
Note: This is available as of OpenCost v1.118.
I wouldn't have imagined spending an entire summer working on integration tests for OpenCost after watching a KubeCon video. By cosmic karma, I came across a mentorship under the Linux Foundation for writing Integration tests for OpenCosts Enterprise readiness. I spent my first few hours frantically reading OpenCost docs to deploy the demo in my local environment and draft my application.

At last week’s KubeCon North America, OpenCost shared exciting updates about our project, including our new status as a CNCF Incubating Project! This milestone underscores our commitment to open-source excellence and the trust the community has placed in OpenCost as a leading solution for Kubernetes cost management. In this post, we’ll recap the Kubecon highlights, including details on our latest plugins, upcoming integrations, and our $1,000 reward for accepted community plugin contributions. Check out Alex Meijer’s KubeCon session on OpenCost plugins here on YouTube.

If you didn’t hear the news already at Kubecon, we’ve released several new plugins to expand OpenCost’s integrations with essential tools and platforms. Here’s a look at the capabilities each plugin brings:
Our backlog is shaped by community feedback. Below are a few examples of plugins we are looking to build, but you can check out the full backlog on our GitHub issues page.
In addition to these updates, OpenCost is inviting community contributions by offering a $1,000 reward + a box of OpenCost swag for each accepted plugin. This reward is part of our commitment to building a robust, community-driven ecosystem of cost management tools for Kubernetes. If you have experience with a particular tool or service that could benefit other OpenCost users, we’d love to collaborate with you!
Visit our Plugin Docs for the full details on how to install OpenCost plugins in your environment. In general, installing a plugin is as simple as:
Thank you to everyone who joined us at KubeCon! OpenCost’s new status as a CNCF Incubating Project represents a significant step forward, and we’re excited to grow with the community. For those who missed the session, watch Alex Meijers’ KubeCon talk here on YouTube and join us on GitHub to share your feedback and ideas. Together, let’s build a powerful and open ecosystem for cost management!

The OpenCost project proudly announces that we’ve reached CNCF Incubating status! This milestone in our journey underscores the significant dedication the project has received from the community that contributes to OpenCost. We’d like to thank the developers, Kubernetes practitioners, and FinOps teams from organizations across the globe that continue to make this project meaningful.

Headlamp is an open source Kubernetes UI that focuses on usability and can be extended via plugins. It is available as a web or desktop application. Learn more about it at headlamp.dev.

OpenCost is one of CNCF's leading open-source projects that offers real-time native cost monitoring for Kubernetes environments, providing visibility to developers and companies on the costs linked to their cloud-native applications. With OpenCost, one can trace the costs of single workloads, namespaces, and even particular labels in your Kubernetes cluster. The continuous granular cost visibility that OpenCost provides help in effectual usage of resources and better budgeting.
