About Flyte

Flyte is a runtime for orchestrating AI workflows. It recovers from infrastructure failures such as OOM kills and node interruptions, and from code failures by retrying and resuming from the failed task with the same inputs.

Workflows are written as plain async functions, with TaskEnvironment declarations for images, resources, secrets and retry policy. The same API can serve long-running apps such as model endpoints and dashboards, with integrations for tools including Spark, Ray, PyTorch Elastic, BigQuery, Snowflake, vLLM and SGLang.

Key features

  • Resume from failed task with same inputs after infra or code failure
  • Write tasks as plain async functions in Python with type-checked I/O
  • Declare images, resources, secrets and retry policy in TaskEnvironment
  • Serve long-running apps including vLLM, SGLang, FastAPI and Streamlit
  • Run same code locally, on devbox, or on cluster
  • Integrate with Spark, Ray, PyTorch Elastic, BigQuery and Snowflake
Best for: Teams developing Python-based AI workflows that need failure recovery and production scaling.
Good for
  • Resumes interrupted runs from the failed task instead of restarting pipelines
  • Runs the same code locally, on a devbox, or on a cluster
  • Provides SDKs in Python, TypeScript, Rust, Go, and Mojo
