What is GitHub?
GitHub sets a December 8 cutoff for ARM32 Actions runners and opens AI Scan to the API.
GitHub's week splits between Copilot supply and platform upkeep. Claude Fable 5.2 and Gemini 4 Carbon reached general availability in Copilot, issue types reached personal-account repositories, and enterprise GitHub Apps can assign Copilot seats. Since then it has added REST control over code scanning's AI Scan, a Cloudflare service-token detector and direct links to public monitoring alerts, and announced that hosted Actions runners stop running ARM32 jobs on December 8.
What is Rivet?
Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.
Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.
GitHub vs Rivet: editorial side-by-side
GitHub
10.0DEVOPSCOLLAB
GitHub sets a December 8 cutoff for ARM32 Actions runners and opens AI Scan to the API.
◆ Current state
GitHub's week splits between Copilot supply and platform upkeep. Claude Fable 5.2 and Gemini 4 Carbon reached general availability in Copilot, issue types reached personal-account repositories, and enterprise GitHub Apps can assign Copilot seats. Since then it has added REST control over code scanning's AI Scan, a Cloudflare service-token detector and direct links to public monitoring alerts, and announced that hosted Actions runners stop running ARM32 jobs on December 8.
◆ Where it's heading
Two deadlines now land on December 8: Dependabot alerts pausing on year-idle repositories and the end of ARM32 job execution on hosted runners. GitHub is pruning what it supports while putting its AI security features behind APIs that organizations can script.
◆ Prediction
Expect AI Scan to move from public preview toward general availability with more organization-level controls, and more retirement notices timed around December 8.
Rivet
7.5DEVOPS
Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.
◆ Current state
Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.
◆ Where it's heading
Rivet keeps turning its S3-backed storage engine into features for agent workloads. Copy-on-write forking follows from the 3.0 storage design and gives agents a cheap way to branch a session, try something and discard it. The SDK and auth work of the past two months points to Rivet positioning actors as the runtime for agent backends.
◆ Prediction
Forking is likely to show up next in agentOS and the Pi integrations as a way to branch agent runs; the entries do not say when 3.0 leaves preview.
