The honest brief

Anyscale

Built by Ray's creators — runs training, batch inference, and data processing on your own multi-cloud GPUs, not a fixed serverless endpoint.

  • Built by the original Ray creators
  • Scales across AWS/GCP/Azure GPUs
  • One engine for training, data, and inference
  • Enterprise security and observability
  • Aimed at ML engineers, steep for beginners
  • Usage-based GPU costs add up
  • Overkill for small single-node jobs

Modal

Define GPU infra in Python decorators with 2-4s cold starts — no YAML, Dockerfiles, or managed-stack lock-in.

  • Python-decorator infra, no YAML/Dockerfiles
  • Scale-to-zero, pay only when running
  • Scales to hundreds of GPUs
  • Free monthly starter credits
  • SDK lock-in; migrating means rewriting
  • No managed vLLM/TensorRT setup
  • Costs climb under heavy usage
  • Billing hard to predict

When to pick which

Both cover Fine-tuning / training, Model inference / serving, and GPU compute.

Pick Anyscale if you need Embeddings and ETL / data pipeline.

  • Embeddings (secondary capability)
  • ETL / data pipeline (secondary capability)

Pick Modal if you need Sandboxed code execution and App / agent deployment.

  • Sandboxed code execution (secondary capability)
  • App / agent deployment (secondary capability)

They share capabilities, but each leads with different ones as a headline job:

Anyscale is built around Fine-tuning / training.

  • Fine-tuning / training (primary capability)

Modal is built around Model inference / serving.

  • Model inference / serving (primary capability)
