Startup Anthropic has introduced two new AI models at once: the large Claude Opus 4 and the medium Claude Sonnet 4. These are the best models for programming today.
Key Features:
🔜 In most benchmarks, both models outperform GPT-4.1, o3 and OpenAI's latest codex-1, as well as Google's newest Gemini 2.5 Pro. Meanwhile, the "junior" Sonnet 4 doesn't lag far behind Opus 4, but the larger model works much better in agentic tasks.
🔜 Opus 4 can solve complex tasks and work steadily on the most challenging requests for several hours.
🔜 In agent mode, the models don't try to make their work easier by looking for "shortcuts" but honestly complete the assigned tasks.
🔜 The models can use deep reasoning before answering and use multiple tools simultaneously.
🔴 We've already added Sonnet 4 with deep reasoning mode to our bot!
