What happened

On February 5, Anthropic released Claude Opus 4.6 with “agent teams”: several Claude Code sessions that divide a large coding job and work in parallel. It can read about a million tokens at once.
The same day, OpenAI released GPT-5.3-Codex, a model made for long coding tasks.

Why it matters for you

Programming is the first field where AI agents do long, real work. Even non-programmers can now build small tools (data cleaning, web pages, scripts) by describing them.
