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.
A gateway sits on every request, so its runtime footprint charges rent forever. Numbers below are from the reproducible 29 August 2026benchmark run - GoModel 0.1.83 against LiteLLM 1.98.0, same mock backend, same AWS box.

| Category | GoModel | LiteLLM |
|---|---|---|
| Measured on the hot path | ||
| Latency overhead (p50) | 2.35 ms | 42.44 ms |
| Latency tail (p99) | 8.80 ms | 61.93 ms |
| Sustained throughput | 3,610 req/s | 250 req/s |
| Peak RAM under load | 42.7 MB | 2,173 MB |
| Efficiency (req/s per CPU %) | 36.5 | 2.0 |
| Cold start to first request | 0.58 s | 31.25 s |
| Docker image (compressed) | 14.4 MB | 353.9 MB |
| Beyond the benchmark | ||
| Runtime & deployment | One Go binary | Python + per-vCPU workers |
| Provider coverage | 31 providers | 100+ providers |
| Config | Env vars + optional YAML | YAML config file |
| Audit logs | Included, MIT | Enterprise license |
| SSO & access control | OIDC SSO in GoModel Pro, no seat cap | Enterprise license, SSO capped at 5 users on free |
| Dependency surface | Small, std-lib-heavy Go tree | Large Python dependency graph |
| License | MIT | MIT core + enterprise license |
Benchmark: 20,000 requests per workload at concurrency 10, five randomized trials, six API workloads, on an AWS c7i.large (2 vCPU, 4 GiB). 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.
Different teams optimize for different things. A fair split, based on what each project actually ships today.
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.
