How to Reduce LLM API Costs in Development

Spotify cut Claude Code token spend by 90% with model routing. Here's how orchestration layers slash AI coding costs without a platform rebuild.

A single predicted token tile sits before a vast grid of identical tiles, above which rises an intricate branching lattice structure built from the same repeated unit, illustrating how simple next-token prediction gives rise to complex emergent structure.

How Do LLMs Actually Work? Beyond 'Next-Token Predictor'

LLMs predict the next word, but that training objective builds real internal reasoning. Here's the proof, including a 13M-line Lean proof of Fermat's Last Theorem.

A flat predictive tile connects to a rising sequence of increasingly layered, volumetric cubes, illustrating the shift from predicting a single token to simulating a full world state.

What Is AI World Modeling?

AI world modeling means predicting the next state of an environment, not just the next word. Here's what it is, where it came from, and why it matters for coding agents.

What Hardware Do You Actually Need to Run LLMs Locally?

What GPU, memory, and budget you actually need to run a 27B-class model like Qwen3 locally, plus the break-even math against API pricing.

Nvidia's Hugging Face Deal: What It Means for Open-Source AI

Nvidia's reported $12.9B bid for Hugging Face would put open-source AI's biggest hub under one chipmaker's control. Here's the impact and why owning your infrastructure matters.

What Is an AI Agent Multiplexer?

An AI agent multiplexer runs and monitors multiple AI coding agents at once, like tmux with status awareness built in. Here's how it works and who uses it.
