GoModel vs LiteLLM

Both put one API in front of many AI providers. The difference is what that layer costs on every request: GoModel is a single Go binary on the hot path, LiteLLM a Python proxy with a much larger provider catalog. Here is how they compare, measured and honest.

GoModel vs LiteLLM Comparison

A gateway sits on every request, so its runtime footprint charges rent forever. Numbers below are from the reproducible June 2026 benchmark - four gateways (GoModel, LiteLLM, Portkey, Bifrost), same mock backend, same AWS box.

Benchmark: 8,000 requests per workload at concurrency 10, six API workloads, two randomized trials on an AWS c7i.large. LiteLLM ran its recommended two workers; retries and GoModel's circuit breaker were disabled for fairness. LiteLLM's broader provider catalog is a real advantage - the benchmark measures the request path, not product maturity.

Which gateway fits your setup?

Different teams optimize for different things. A fair split, based on what each project actually ships today.

Choose GoModel when

Gateway overhead is real money or real latency: high request volume, latency-sensitive products, or fast local models where 30 ms per call dwarfs inference.
You want audit logs, budgets, rate limits, and the admin dashboard under a plain MIT license - no enterprise tier.
Operations should stay small: one binary or a 16 MB image that runs the same on a laptop, an edge box, or Kubernetes.
You serve both OpenAI SDK and Anthropic SDK clients from one endpoint.

LiteLLM is the better fit when

You need long-tail providers beyond GoModel's 22 - LiteLLM's catalog of 100+ is a genuine advantage.
Your platform tooling is Python-first and already builds on the LiteLLM SDK rather than the proxy.
You depend today on features GoModel has on the roadmap, like SSO and OAuth 2.0.

Try it against your own workload

Benchmarks are an argument; your traffic is the proof. GoModel speaks the OpenAI and Anthropic APIs natively, so pointing an existing app at it is a base-URL change.

1 · Run GoModel

docker run --rm -p 8080:8080 \
  -e LOG_FORMAT=text \
  -e OPENAI_API_KEY="your-openai-key" \
  enterpilot/gomodel

2 · Point your SDK at it

from openai import OpenAI

client = OpenAI(
    base_url="http://localhost:8080/v1",
    api_key="your-gomodel-key",
)
