With Claude Opus 4.6 launching in February 2026 and GPT-5.2 arriving in December 2025, we now have two heavyweight frontier models to compare. Here's how they stack up across the dimensions that matter most for real-world work.

Anthropic released Claude Opus 4.6 on February 5, 2026, and it's a significant leap forward. With a 1M token context window, 128K output tokens, and agent teams built into Claude Code, this model is redefining what's possible with AI-assisted development.
