Anthropic Unveils Claude 4: Next-Gen Models for Coding and Advanced Reasoning

Anthropic has launched Claude Opus 4 and Claude Sonnet 4, setting a new bar for coding, advanced reasoning, and AI agents. Opus 4 is touted as the world's best coding model, excelling in complex, long-running tasks and agent workflows. Sonnet 4 significantly improves upon its predecessor, offering superior coding and reasoning with more precise instruction following. The launch also includes extended thinking with tool use (beta), new model capabilities (parallel tool use, improved memory), the general availability of Claude Code (with GitHub Actions, VS Code, and JetBrains integrations), and four new Anthropic API features. Both models are available via the Anthropic API, Amazon Bedrock, and Google Cloud's Vertex AI.
