The self-hostable technology runs on plain Node.js, Bun, or Rust, deploying flexibly across local setups, Docker, Kubernetes, or virtual machines. By consolidating multiple actors within a single node process, the system cuts down resource consumption and completely bypasses conventional virtual machine boot times. Each instance operates alongside a dedicated SQLite database that hibernates when idle to curb cloud infrastructure expenses. The platform also includes operational utilities like OpenTelemetry logging, cross-node fault tolerance, and installable tool packages for assistants like Cursor, Claude Code, and Windsurf.

Rivet is an orchestrator for agentic workloads built on the actor model. Each Rivet Actor is a long-lived process with in-memory state, a SQLite database, WebSockets for realtime, and scheduling, addressed by key. Create one per agent, session, user, or tenant, and run it on plain Node.js, Bun, or Rust.
- 72 KB per Actor: Actors share a node process instead of each booting a sandbox, so one server holds hundreds of thousands.
- 4.99 ms p99 cold starts: No image pull and no VM boot.
- SQLite backed by S3, at SSD speeds: 1.07 ms durable writes and 1.36 ms reads at p99, for about 10.4× less than…
The technology giant is expanding its artificial intelligence portfolio by introducing a new iteration aimed at handling extended media formats more economically. While this release targets improved operational efficiency, developers and enterprise clients must await further documentation to evaluate the full performance changes. Comprehensive technical benchmarks remain pending following the initial product rollout.
Google is facing claims that a student used an artificial intelligence chat service on a school laptop in the United States to plan a suicide attempt. Details regarding the specific AI tool involved and the school district have not been disclosed.
The legal action accuses the tech giant of aggressively pushing artificial intelligence into educational settings without disclosing the severe risks to young users. Filed by parents in California and relocated to federal court, the suit seeks monetary damages following an incident involving school-issued technology. The case intensifies scrutiny over Big Tech's deployment of generative algorithms in classrooms without adequate safeguards for vulnerable children.
