Symphony and Tale meet at the task-to-agent boundary, but they are different kinds of choice. Your decision is whether to adopt a shared project application or operate an orchestration service around your existing engineering process.
Compare at a glance
| Criterion | Tale | OpenAI Symphony |
|---|---|---|
| Product layer | An existing project application for shared tasks, agents and review. | An OpenAI specification and experimental reference implementation for tracked engineering work. |
| Coordination | Equipped manager agents can delegate eligible work within delegation and capacity limits; results return for review. | Turns tracked work into isolated agent runs; the example uses Linear, CI and review feedback. |
| Evaluation boundary | Test configured tools and credentials across code, research and document handoffs. | An engineering preview intended for trusted environments. |
Keep the product layer in view
OpenAI describes Symphony as a specification and experimental reference implementation that turns tracked work into isolated agent runs. The repository's example watches a Linear board and returns evidence such as CI and review feedback. It labels the project an engineering preview for trusted environments. Symphony repository.
Tale supplies the project workspace people use to create and assign tasks, discuss progress and inspect reports and files. Project agents have configured runtimes, instructions and tools. A manager agent can start eligible work within delegation and capacity limits; a successful task returns for review. This can support a code change, a research brief or a set of campaign documents in one project.
Consider Symphony if your engineering team wants to implement or operate the orchestration layer while retaining its issue tracker and repository practices. Consider Tale if you want colleagues across functions to work in a shared project application. Neither choice removes the need to prepare tools, credentials and an execution environment.
Test the whole operating loop
Use one bounded repository task with a failing test and a clear acceptance criterion. Add a separate explanatory document that a nontechnical colleague must review. In each evaluation, record who prepares the environment, starts work, notices a failure, requests changes and accepts the result.
Then ask what your team would maintain: tracker integration and orchestration behavior, or a configured application deployment. Compare the daily responsibilities and handoffs, not an invented score for which system is more autonomous. Tale's task review is also separate from connector approval policies; define both explicitly if the task can change external systems.
