LiteLLM vs Ollama
Self-host pick — both replace OpenAI API (LLM inference API).
Both LiteLLM and Ollama self-host as a replacement for OpenAI API (LLM inference API). Pick LiteLLM if you want teams that want one OpenAI-shaped endpoint in front of many backends (mix of self-hosted + hosted Anthropic + hosted OpenAI for fallback); pick Ollama if you want single-machine deployments and laptops; the easiest on-ramp from OpenAI for a developer team. Both are MIT-family licensed and similar to set up.

| Setup time | 15min docker-compose (proxy + Postgres for usage logs) | 5min single binary |
| Monthly cost | $5 VPS for the proxy itself; the underlying model server (Ollama / vLLM / OpenAI passthrough) is the real cost line. | Free on a workstation with a 16GB+ GPU; ~$200/mo for an A10/RTX 4090 cloud GPU; CPU-only works for 7B models but is too slow for production. |

Good fit for
LiteLLM
Teams that want one OpenAI-shaped endpoint in front of many backends (mix of self-hosted + hosted Anthropic + hosted OpenAI for fallback).
Weak at:Not a model server itself — you still need Ollama/vLLM/cloud APIs behind it; LiteLLM is glue, not GPU.
Ollama
Single-machine deployments and laptops; the easiest on-ramp from OpenAI for a developer team.
Weak at:Multi-tenant serving and batched throughput — Ollama serializes requests; for concurrent traffic switch to vLLM.
