# Caveman vs Bifrost for AI gateway and agent costs

Bifrost is built for gateway infrastructure: provider access, load balancing, fallbacks, caching, and governance. Caveman's public local tools focus on reducing eligible context while an agent works. If Bifrost already handles your production routing, you can evaluate the context problem without replacing that infrastructure.

Caveman Router and Platform are private-access products. A production gateway replacement should be a separate pilot with explicit capability and policy checks.

## Gateway speed and agent cost are different measurements

| Question | What to measure |
| --- | --- |
| Does the gateway add too much latency? | Gateway overhead under representative load |
| Does failover preserve the application's contract? | Errors, retry behavior, model capabilities, and policy |
| Can a response be reused? | Cache hit rate and correctness for the cache's scope |
| Does the agent resend too much context? | Model input across the full task |
| Did an optimization pay off? | Accepted output, complete usage, latency, and operating cost |

[Bifrost's project](https://github.com/maximhq/bifrost) documents an OpenAI-compatible gateway, native SDK integration paths, semantic caching, plugins, and deployment options. Some enterprise capabilities have a separate commercial boundary. Check the edition you intend to run.

Bifrost publishes gateway performance results. Those do not establish how much context a coding agent will send or whether a compressed agent result remains correct. Caveman's task benchmarks answer a different question and should not be compared with gateway microseconds as if they measured the same thing.

## What Caveman can add

A gateway may forward a request quickly while the request still contains thousands of unnecessary tokens. Caveman can replace eligible tool content with a smaller view and retain the original locally for retrieval.

That is useful when an agent repeatedly carries search results, logs, or structured records through several turns. It is less useful when the request is already small, the content is unsuitable, or repeated input is cheap because of provider caching.

Test a complete task using the same model and final acceptance check. Count recovery and retries. Use [the measurement guide](/guides/measure-agent-cost) to keep provider usage, local estimates, and bills distinct.

## Keep governance where it is enforced

Bifrost virtual keys, provider restrictions, budgets, guardrails, and plugins belong to its request path. A direct-provider Caveman trial does not automatically retain them.

Use an isolated task and credentials appropriate for that trial. If the candidate must remain behind Bifrost, validate the exact protocol, model naming, authentication, and recovery path before sending production traffic through both layers.

Do not stack caches or retry policies without deciding which layer owns each behavior. Duplicate retries can turn a transient error into several billed calls. An unexpected cached response can hide whether the compression candidate reached the provider at all.

## When to choose each

Choose Bifrost for gateway requirements that its deployment and edition meet. Choose local Caveman when repeated agent context is the cost you can test today. Keep both when their responsibilities are distinct and the combined path passes your checks.

Consider a private Caveman Platform pilot when the next question is how agent spend connects to ownership, delivered work, and proposed improvements. That is broader than replacing a fast gateway.

The [Bifrost switching guide](/switch/bifrost) covers configuration inventory, a local trial, compatibility checks, and rollback. The [gateway selection guide](/guides/choose-ai-gateway) helps compare infrastructure requirements independently of compression claims.
