Teams building AI, ML, and agentic systems know the pain of manually babysitting and fixing infra-caused failures:

• Out-of-memory (OOM) errors
• Node interruptions
• Container pre-emption

These failures prevent workflows from truly durable execution. And the more you scale your workloads, the worse this problem becomes.

Temporal was designed as a durable microservices orchestrator. But because it can’t orchestrate compute, it can’t solve the 50% of failures caused by compute infra:

• Replay log. Like Union.ai, when an execution fails, Temporal replays completed events to reconstruct state and picks up from where it left off, without re-running work that already succeeded.
• No diagnosis. While Temporal can detect infra-caused failures, it isn’t able to clarify the cause of these failures. It leaves diagnosis to the user.
• Can’t provision resources. Without infrastructure-awareness, Temporal cannot fix these failures by re-provisioning compute resources.

If you’re running simple microservices, these compromises can be totally fine. But if you’re running AI or agentic projects, you’ll need an AI orchestrator.

Union.ai, the enterprise Flyte platform, is expressly designed for AI engineers. Using its infrastructure-awareness, teams can build workflows that are:

• Compute-aware, autonomously solving both logic and infra-caused failures like OOM errors
• Self-healing, so pipelines that fail autonomously recover and continue
• Dynamic, so your AI systems and agents can make decisions on the fly at runtime
• Authored in pure Python, so you can easily go from local dev to production in your cloud‍
• Scalable and efficient, handling large task fanout and parallelism with ease

The platform deploys to your secure cloud

• Enhanced scale and performance, with significantly improved actions/run, concurrency, and task startup time
• End-to-end AI lifecycle support, including orchestration, training and fine-tuning, and inference
• Developer-loved UI, for faster, easier development cycles
• Observability, including for data lineage, resource usage, failure logs, etc.
• Portability to open-source, for teams looking to avoid lock-in

Teams report that Union.ai accelerates them from prototype to production, cutting iteration cycle time in half. 

The Union.ai team offers high-touch support to ensure users are successful.

Flyte 2 OSS is the most powerful open-source AI orchestrator, bringing Flyte’s core data model, scalability, and reliability to DIY teams. While it lacks some enterprise capabilities of Union.ai, it remains the most capable open-source AI orchestration tool available. It’s trusted by teams worldwide with 80M+ downloads and growing.121
