Why OmniCache?

• Sub-Millisecond Vector Semantic Caching (<0.8ms): Pure in-memory 512-d feature projection embedder matches paraphrased queries with zero remote API lag.
• Coding Agent Tool-Loop Accelerator: Caches idempotent tool calls (read_file, git status, grep) for Claude Code, Cursor, and Devin, cutting agent loop runtimes from 15s to 350ms.
• Adaptive Cost Arbitrage & Model Cascade: Automatically routes simple formatting / classification queries to Gemini 2.5 Flash ($0.05/1M), slashing non-cached cloud bills by 75%.
• Multi-Modal Vision Perception Cache: Uses 64-bit Perceptual Hashing (dHash) to match UI screenshots, invoices, and images in <0.3ms at $0.00.
• Zero-Knowledge Privacy Vault: Reversible tokenized masking of SSNs, credit cards, emails, and API keys before sending upstream (HIPAA & SOC2 ready).
• Token Jitter SSE Streaming: Smoothly replays cached tokens at natural typing speed (~65 tokens/sec) with <10ms Time-To-First-Token, fixing the 0ms UI typing blast.
• Built-in System Doctor & Benchmarker: Instant omnicache doctor and omnicache benchmark micro-profiling right from the terminal.
• Enterprise Prometheus & CSV Ledger: Exposes /metrics for Grafana and one-click /v1/cache/export CSV financial downloads.

Quickstart (1-Line Integration)

1. Install & Start OmniCache

# Install from PyPI
pip install omnicache-proxy

# Start proxy in background
omnicache &

The gateway is now live at http://localhost:8000 with the analytics dashboard at http://localhost:8000/dashboard.

2. Connect Your Application (Zero Code Changes)

Claude Code (Terminal Assistant):

ANTHROPIC_BASE_URL="http://localhost:8000" claude

Python (OpenAI SDK):

from openai import OpenAI

# Simply route baseURL to OmniCache
client = OpenAI(
    api_key="your-api-key",
    base_url="http://localhost:8000/v1"
)

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "How do I optimize SQL queries?"}]
)
print(response.choices[0].message.content)

TypeScript / Node.js:

import OpenAI from "openai";

const openai = new OpenAI({
  apiKey: "your-api-key",
  baseURL: "http://localhost:8000/v1"
});

Live Web Telemetry Dashboard

Open http://localhost:8000/dashboard in your browser to inspect live:

• Total Cost Saved ($ USD) & Tokens Saved (100% Free)
