LiteLLM Consulting
Neul Labs offers focused consulting around LiteLLM in production: audits, performance and cost tuning, multi-provider routing design, and incident response. We work with teams that have already shipped LiteLLM and need help making it reliable, fast, or cheap.
Who this is for
- Engineering teams running the LiteLLM proxy in production and hitting performance, reliability, or cost issues.
- Architects designing a multi-provider LLM strategy and choosing between LiteLLM, LangChain, and rolling your own.
- Platform teams building internal LLM gateways on top of LiteLLM.
- Teams that recently inherited a LiteLLM deployment and want a sanity check before they touch it.
