LLM Cost Optimization

The operational playbook for cutting LLM spend without cutting quality. Model routing, caching, batching, and the metrics that actually matter.

Tool Guide

LiteLLM Guide

The definitive guide to LiteLLM for multi-model routing — OpenAI-compatible proxy, fallbacks, cost tracking, and self-host setup for production AI apps.

Workflow

Build an MCP Server from Your API

Wrap your REST or GraphQL API as an MCP server so Claude Desktop, Cursor, and any MCP client can call it — write once, use everywhere.

Comparison

Cheapest AI APIs

Per-million-token cost comparison across providers, with notes on where the cheap models are actually good enough.

Comparison

Local Models vs API Models

Should you run LLMs on your own hardware or pay OpenAI and Anthropic? An honest comparison on privacy, cost, latency, quality, and the ops burden nobody talks about upfront.
