Anthropic's new Claude 4 AI models can reason over many steps | TechCrunch

Key takeaways:

Anthropic launched Claude Opus 4 and Claude Sonnet 4, advanced AI models that handle complex reasoning, long tasks, and programming effectively.
Sonnet 4 is available to free and paid users; Opus 4 is exclusive to paid users and more powerful, priced at $15/$75 per million tokens via API.
Opus 4 beats leading models like Google Gemini 2.5 and OpenAI GPT-4.1 on coding benchmarks but doesn’t outperform all models in every area.
Both models can reason in steps, use tools like search engines, store useful info in memory, and show simplified reasoning summaries.
Anthropic is updating Claude Code with IDE integration and a new SDK, aiming to improve AI-assisted coding and developer workflows.
