GitHub Spark in public preview for Copilot Enterprise subscribers (github.blog)

GitHub today opened Spark in public preview for Copilot Enterprise customers — a built-in, end-to-end prototype-to-production flow that turns natural-language prompts into full frontend and backend apps inside GitHub. Spark bundles hosting, data, LLM inference, deployments, auth, and repo creation so teams can validate ideas quickly, share interactive prototypes, and move working concepts into production without stitching together third‑party services. It integrates with repos, Dependabot, Codespaces and Copilot (including Copilot agent mode), supports visual editing or code with Copilot completions, and offers one‑click deployments and repo synchronization to avoid trapped sandboxes. For the AI/ML community Spark is significant because it lowers the operational and integration friction of shipping LLM-powered features: developers can add AI from OpenAI, Meta, DeepSeek, xAI and others without managing API keys, and Spark messages consume the premium requests included in Copilot plans. Enterprise admins control rollout (Spark is disabled by default and must be enabled via Enterprise Policies → Copilot → Features, with org-level options), so governance and security remain centralized. As a public preview the UI and capabilities may change, but Spark signals a push toward tightly integrated, developer-centric platforms that accelerate prototyping and productionization of AI-first applications.
