Courier Symphony is in active development and validation.
Keep AI work moving.
A continuity and orchestration layer for AI work across providers, machines, and execution environments — so a session, a machine, or a rate limit never means starting over.
For potential users and partners. No signup, no tracking on this page.
What it does
- Durable continuity and checkpointing
- Capability-aware routing
- Host-aware bounded capacity
Concurrency follows what the machine can bear. - Safe parallelism
- Recovery instead of blind repetition
After provider limits or host and process failures, work continues — never a blind duplicate execution of the same effect. - Human gates for spending/credentials/sensitive actions
How it works
- 1
Checkpoint
Progress, decisions, and durable state are recorded as work runs — including across machines.
- 2
Route
Each next step is assigned to a capable, available environment.
- 3
Recover
When a provider, machine, or process fails, the work resumes from its checkpoint on a healthy path.
Status
Courier Symphony is in active development and validation. There is no public signup, no pricing, and no launch date to announce — if you work on long-running AI systems, we would like to hear from you.
