Stop bleeding money on LLMs: Introducing Otellix for Go

Working with Large Language Models (LLMs) in production is magic. The honeymoon phase usually lasts about a month—right until you get the inevitable API bill. If you’ve ever accidentally put an LLM generation call inside a deeply nested background loop (don't lie, we've all done it), or if you just want to prevent one heavy user from eating your organization's daily budget, then you probably know the pain. Current LLM observability platforms are either heavy SaaS products with their own per-event pricing, or they completely lack hard budget enforcement. I wanted something free, OpenTelemetry-native, and focused on hard budget limits for cost-constrained applications in Go. So, I built Otellix . What is Otellix? Otellix is a production-grade LLM observability SDK for Go built entirely on top of OpenTelemetry. It wraps the official SDKs for Anthropic, OpenAI, Gemini, and Ollama, allowing you to intercept and track costs without drastically altering your codebase. 1. Unified Tracing & Met
