July 2025 Summaries

Riza has announced the shutdown of its hosted Code Interpreter API, which will cease operations on October 1st, 2025, due to insufficient growth in demand for fast LLM-generated code execution. While new account signups are being disabled immediately, existing users can continue using the self-hosted container with an offline license key indefinitely. The API, introduced in April 2024, served developers needing efficient execution of agent-generated code, particularly in JavaScript and Python, but it failed to attract enough projects to justify continued investment. Users are advised to migrate their workloads to another provider within the next month to ensure uninterrupted service, and support for microVM-based custom runtimes will end on August 1st, 2025. Riza has communicated this decision to its users and encourages those affected to reach out via Discord or email for assistance with migration or further inquiries.

On August 1st, 2025, support for microVM-backed custom runtimes will be disabled, and users are advised to transition to V8-based runtime engines, which offer faster startup and build times along with easier self-hosting capabilities. Starting July 2nd, 2025, new custom runtimes will default to the V8 engine, and after August 1st, the creation and usage of microVM runtimes will be restricted except for those in a transition program. A migration guide is available to assist users in reviewing dependencies, creating new V8 runtimes, testing applications, and updating API calls. The company acknowledges the potential disruption caused by this change and offers support through Discord or email to ensure a smooth transition.
