What is GitHub?
GPT-6 Astra lands in GitHub Copilot — OpenAI's long-horizon autonomous coding model is now production-available.
GitHub Copilot is now a multi-model marketplace across OpenAI, Google, and its own models, with GPT-6 Astra and Gemini 3.8 Flash both added this week alongside an upcoming deprecation of older models on October 2. The platform simultaneously ships supply-chain improvements (trusted publishing for npm, CodeQL security detection upgrades) and begins deprecating models that predate the current generation — a sign of maturing infrastructure rather than feature sprawl.
What is Rivet?
Rivet's Dynamic Apps let you deploy AI-generated apps via V8 isolates — zero-sandbox infrastructure for user-generated code.
Rivet is shipping infrastructure for the agentic application layer: Dynamic Apps (V8 isolates for user-generated apps that scale to zero), Durable Streams for Actors, and an agentOS execution API that runs JavaScript and Python natively rather than through bash. The architecture thesis — V8 isolates instead of container sandboxes — is now production across the Actor, Streams, and Cron layers.
GitHub vs Rivet: editorial side-by-side
GitHub
10.0DEVOPSCOLLAB
GPT-6 Astra lands in GitHub Copilot — OpenAI's long-horizon autonomous coding model is now production-available.
◆ Current state
GitHub Copilot is now a multi-model marketplace across OpenAI, Google, and its own models, with GPT-6 Astra and Gemini 3.8 Flash both added this week alongside an upcoming deprecation of older models on October 2. The platform simultaneously ships supply-chain improvements (trusted publishing for npm, CodeQL security detection upgrades) and begins deprecating models that predate the current generation — a sign of maturing infrastructure rather than feature sprawl.
◆ Where it's heading
GitHub is converging on an agentic coding platform where the model choice is abstracted behind Copilot's interface. The rapid multi-model onboarding signals that GitHub treats model availability as a competitive table-stakes feature rather than a differentiation moment. The real differentiation bet appears to be in the supply-chain and security layer: trusted publishing, CodeQL improvements, and privacy-safe APIs.
◆ Prediction
The October 2 model deprecation will likely trigger another wave of new-model announcements to maintain feature parity. The next meaningful differentiation move is probably around agentic task completion — Copilot Workspace functionality expanding to autonomous PR generation and review at scale.
Rivet
6.3DEVOPS
Rivet's Dynamic Apps let you deploy AI-generated apps via V8 isolates — zero-sandbox infrastructure for user-generated code.
◆ Current state
Rivet is shipping infrastructure for the agentic application layer: Dynamic Apps (V8 isolates for user-generated apps that scale to zero), Durable Streams for Actors, and an agentOS execution API that runs JavaScript and Python natively rather than through bash. The architecture thesis — V8 isolates instead of container sandboxes — is now production across the Actor, Streams, and Cron layers.
◆ Where it's heading
Rivet is building toward a full execution platform for AI-generated code: actors for stateful logic, isolates for sandboxed user code, durable streams for event delivery, and a zero-disk SQLite storage engine for persistence. The Dynamic Apps announcement is the clearest statement of the product's endgame — developers who build products where users generate and deploy their own apps.
◆ Prediction
The next move is pricing and billing for Dynamic Apps runs — the infrastructure is in place, and the V8 isolate model (scale-to-zero, per-request cost) maps naturally to usage-based billing.
