Flow diagram of Anthropic's self-improvement loop showing human direction, Claude Code engineering, and research agent evaluation connected by a recursive feedback path.

Claude Is Now Writing Claude: The Architecture Behind It

More than 80% of the code going into Anthropic's production codebase is now authored by Claude. This is what that pipeline actually looks like — and where it still breaks.

Fine-Tune Llama 3.1 on Multiple GPUs with Axolotl and DeepSpeed

A hands-on walkthrough for running distributed Llama 3.1 fine-tuning jobs using Axolotl's YAML-driven config system and DeepSpeed ZeRO-3. Here we target 2–8 GPU setups on cloud or local hardware.

A technical black and white illustration mapping the database, port, and environment orchestration required for stable multi-agent parallel coding workflows.

Preventing Database and Port Collisions with Concurrent AI Agents

Running parallel AI coding loops? Learn how to automate environment isolation, prevent database contamination, and eliminate network port deadlocks using Git Worktrees and global lifecycle hooks.

Prompt Engineering is a Waste of Time If the Data Pipeline Feeding the Prompt Is Garbage

Why prompt engineering fails on massive repositories. Learn how to use local Tree-Sitter AST mappers and MCP to build high-signal context pipelines.
