Changelog #108: New Serverless GPUs, Auto-deletion and Lifecycle Management for Koyeb Sandboxes, and more

[alisdair]

Hello, and welcome to the first changelog update of 2026!

2026 is shaping up to be even bigger than 2025 for the AI stack: AI agents, AI-generated code, and multi-modal models are changing how all applications are built and deployed. The AI stack becomes a part of all stacks in the same way that cloud became essential.

Just like everyone building in AI, 2025 was a busy year for us. As we saw more and more teams move from PoCs and demos to production, we focused on building the high-performance serverless infrastructure that makes deploying and scaling AI reliable in the real world. We shipped a lot of features and improvements designed to make your AI deployments experience faster, smoother, and more cost effective. You can relive all the highlights in our full Koyeb 2025 Recap.

Now, on to what you really come here for. Here’s what’s new on Koyeb since our last changelog update:

1. New Serverless GPUs: RTX Pro 6000, H200, and B200 Now Available

   We announced three new NVIDIA GPUs to the Serverless GPU line-up: RTX Pro 6000, H200, and B200. The H200 instance is available in multi-GPU configurations (2×, 4×, and 8×).

   These new GPU instances enable high-performance inference for compute-intensive workloads that are memory-bound, latency-sensitive, or throughput-constrained, including long-context and large-model serving. Check out the announcement.

   

2. Koyeb Sandboxes: Auto-deletion and Lifecycle Management

   We’ve added support to automatically delete sandboxes based on user-defined periods. Deletion can be configured to occur after creation or after a period of inactivity when the sandbox is scaled to zero. Read the Sandbox Lifecycle documentation.

3. Koyeb Sandboxes: JavaScript SDK now available

   Koyeb JavaScript SDK is now available for Sandboxes. When we first announced Koyeb Sandboxes, they were only accessible via the Python SDK. Read the JS SDK documentation.
