What is GitHub?

GitHub is bolting model-routing onto Copilot while hardening npm against supply-chain attacks.

GitHub is moving on two parallel fronts. Copilot is evolving from a single-model coding assistant into a multi-model routing platform — Gemini 3.5 Flash just went GA, auto model selection now routes by task, and the web client is actively trimming user-facing model choices. In parallel, npm is being re-engineered as a security-first registry with staged publishing GA and granular install-source controls, while Issues finally picks up typed metadata to compete with dedicated trackers.

What is Rivet?

Rivet stacked three actor primitives and a custom agent VM in 90 days.

Rivet shipped a coordinated set of actor primitives over three consecutive days in February — durable TypeScript Workflows, per-actor durable Queues, and per-actor SQLite that scales to zero — then introduced agentOS in April, a WASM-plus-V8-isolate VM for AI agents claiming ~6 ms cold starts and 32x lower cost than container sandboxes. The platform now spans the data, control-flow, and runtime layers an AI-agent builder otherwise stitches together. A May dashboard redesign followed the heavy platform-primitive push.

GitHub is bolting model-routing onto Copilot while hardening npm against supply-chain attacks.

◆ Current state

GitHub is moving on two parallel fronts. Copilot is evolving from a single-model coding assistant into a multi-model routing platform — Gemini 3.5 Flash just went GA, auto model selection now routes by task, and the web client is actively trimming user-facing model choices. In parallel, npm is being re-engineered as a security-first registry with staged publishing GA and granular install-source controls, while Issues finally picks up typed metadata to compete with dedicated trackers.

◆ Where it's heading

The product is heading toward an opaque, managed Copilot layer where the model choice disappears behind task-based routing, and toward an npm where publishing and consumption are both gated by explicit review steps. The Issues plus semantic search work suggests GitHub wants planning workflows to live on-platform rather than leak to Jira and Linear. Expect further consolidation of the Copilot UX surface and continued supply-chain feature work as the dominant arcs.

◆ Prediction

Look for the cloud Copilot agent to combine the new Fix-with-Copilot dialog with code-review feedback into closer-to-autonomous PR completion. On the registry side, staged publishing will likely grow attestation defaults or become required for high-download packages within a release or two.

1.3

Rivet stacked three actor primitives and a custom agent VM in 90 days.

◆ Current state

Rivet shipped a coordinated set of actor primitives over three consecutive days in February — durable TypeScript Workflows, per-actor durable Queues, and per-actor SQLite that scales to zero — then introduced agentOS in April, a WASM-plus-V8-isolate VM for AI agents claiming ~6 ms cold starts and 32x lower cost than container sandboxes. The platform now spans the data, control-flow, and runtime layers an AI-agent builder otherwise stitches together. A May dashboard redesign followed the heavy platform-primitive push.

◆ Where it's heading

Rivet is positioning itself as the actor-runtime substrate for AI agents: every release this year — Workflows, Queues, SQLite, Sandbox Agent SDK, agentOS — is something developers currently glue together themselves on top of AWS, Fly, or Cloudflare. The cadence is big launches rather than weekly increments; the past month of surface polish suggests the platform-primitive arc has hit a temporary plateau and the focus is shifting to ergonomics and adoption.

◆ Prediction

Expect dev tooling, SDK polish, and a positioning push around agentOS economics relative to Fly Machines, Cloudflare Workers, and AWS Firecracker sandboxes. A managed-cloud variant of agentOS or a v2 of the Sandbox Agent SDK would be the natural next flagship.
