OpenAI's Symphony, released in 2026 as an open-source spec, defines a "ticket-driven AI development" pattern: each Linear issue gets its own Codex agent in its own workspace and runs until the issue reaches a terminal state. This article walks through the spec's core ideas, the Elixir reference implementation, the polling / supervisor / workspace-isolation architecture, and the realistic operational considerations for adopting it — based on publicly available information.

Elixir is a functional language running on the Erlang VM (BEAM), with strengths in concurrency and fault tolerance. Production adopters include Discord, Veeps, and the BaaS platform Solaris. In 2026 it's getting renewed attention through Phoenix LiveView 1.1 and as the language OpenAI chose for its Symphony agent-orchestration reference implementation. This guide covers the history, language characteristics, real production use cases, what makes Phoenix LiveView compelling, and why Elixir matters in the AI agent era — written from a practitioner's perspective.
