Pros & Cons

LiteLLM

Pros

  • Core gateway and SDK are completely free and open source with no feature paywall
  • Extremely wide provider coverage (100-plus LLMs) through one consistent API
  • Proven at large scale with over one billion production requests and major enterprise users like Netflix and Adobe
  • Automatic fallback and load balancing improve reliability across providers
  • Strong observability integrations fit into existing monitoring stacks rather than forcing a new one

Cons

  • Self-hosting and configuring the proxy for production requires real infrastructure and DevOps effort
  • Enterprise features (SSO, audit logs, SLAs) require a custom-priced paid plan
  • Rapidly evolving open-source project can introduce breaking changes between versions
  • Governance features add complexity that may be unnecessary for small teams using a single provider
  • Community support model means response times can vary compared to a dedicated commercial vendor

Ray

Pros

  • Free and open source under the permissive Apache 2.0 license
  • Scales seamlessly from a single laptop to clusters with thousands of nodes
  • Used in production by major AI companies, including reported use in ChatGPT-related infrastructure
  • Comprehensive library ecosystem covering data, training, tuning, and serving in one framework
  • Large, active open-source community with 1,000+ contributors and 34,800+ GitHub stars

Cons

  • Distributed systems concepts add a learning curve compared to single-machine Python tools
  • Self-managing Ray clusters without Anyscale requires nontrivial DevOps expertise
  • Debugging failures across a distributed cluster can be more difficult than single-node debugging
  • Enterprise-grade support and managed infrastructure are only available through the separately priced Anyscale platform

Use Cases

LiteLLM

  • Multi-provider LLM infrastructure — Platform teams centralize access to multiple LLM providers behind one gateway, enabling automatic fallback and cost control across an organization.
  • AI cost governance and chargeback — Organizations track and attribute LLM spend per team, project, or user to manage budgets across many internal applications.
  • Provider migration and redundancy — Teams avoid vendor lock-in by routing through LiteLLM, allowing them to switch or add LLM providers without rewriting application code.

Ray

  • Distributed model training — ML engineers use Ray Train to scale model training across multiple GPUs and nodes without rewriting training code from scratch.
  • Large-scale batch inference and data processing — Data teams use Ray Data and Ray Core to run distributed ETL and batch inference jobs across large datasets.
  • LLM and model serving at scale — Teams building AI products use Ray Serve to deploy and scale model and large language model inference in production.
