FOR AI AGENT DEVELOPERS

Cut inference cost—without rewriting your stack.

BabelFish is a drop-in edge proxy that compiles repetitive LLM calls into deterministic code. Change one URL and your predictable steps run locally.

Deterministic steps become deterministic. Reasoning stays on the model.

Stop burning tokens on predictable steps. Join the beta and see your costs drop.

terminal
# Standard (Expensive, prone to hallucinations)
client = ChatOpenAI(base_url="https://api.openai.com/v1")
# With BabelFish ($0 token cost, 100% deterministic, 10ms latency)
client = ChatOpenAI(base_url="https://api.babelfish.dev/v1")

Every agent call hits the same API. Most of them don’t need to.

Your agent re-classifies the same intents, re-extracts the same fields, and re-validates the same formats—thousands of times a day. Each call adds cost, latency, and a fresh chance to hallucinate.

Redundant calls

Most production LLM calls follow patterns already seen.

Hallucination risk

Every non-deterministic call is another roll of the dice on output quality.

Margin erosion

Per-call API costs × millions of calls = your SaaS margin, gone.

BabelFish watches, learns, compiles.

Change one URL. BabelFish silently profiles execution, clusters repeated call patterns, and compiles safe replacements that run locally—no API, no latency, no hallucinations.

Step 1

Observe

Point your agent at BabelFish. It logs structural call patterns (no PII, no payloads).

Step 2

Learn

Clustering identifies the calls that repeat—and the ones that don’t.

Step 3

Compile

Deterministic code replaces the repeatable calls. Reasoning stays with the LLM.

One line. That’s it.

Swap your base URL. No SDK, no config files, no infra changes.

app.py
# Before
client = ChatOpenAI(base_url="https://api.openai.com/v1")
# After — that’s the entire integration
client = ChatOpenAI(base_url="https://api.babelfish.dev/v1")

Compatible with any OpenAI-compatible client — LangChain, LlamaIndex, LiteLLM, and raw SDKs.

What compiles?

BabelFish targets the agent steps that are repetitive and deterministic — leaving genuine reasoning to the LLM.

Classification & routing

Intent detection, topic routing, category assignment.

Structured extraction

Name, address, date, amount — parsed from known formats.

Guardrail checks

PII detection, toxicity filters, format validation.

Format transformation

JSON ↔ XML, markdown → HTML, schema migration.

Retrieval re-ranking

Static relevance scoring that doesn’t change per query.

Prompt chains

Multi-step prompts with fixed templates and variable slots.

Every compiled path is tested before it runs.

BabelFish doesn’t just compile — it validates. Canary testing, automatic rollback, and continuous drift detection ensure compiled paths stay accurate.

Canary deployment

5% of traffic tests the compiled path against the LLM baseline. Mismatch → instant rollback.

Drift detection

Continuous monitoring catches when real-world inputs diverge from training patterns.

One-click rollback

Any compiled path can revert to the original LLM call in under 1 second.

See what your agents actually do.

Nexus is the governance and observability layer for your agent fleet. Visualize execution paths, set guardrails, and audit every decision — before and after compilation.
