Google-backed Anthropic has launched its latest AI models, Claude Opus 4 and Claude Sonnet 4. These models offer advanced coding and reasoning skills.
Claude Sonnet 4 is available for free users, while Opus 4 is for Pro users. Both models are accessible via the Anthropic API, Amazon Bedrock, and Google Cloud's Vertex AI.
Anthropic claims Claude Opus 4 is its most powerful model yet, excelling at coding and complex problem-solving. Claude Sonnet 4 balances performance and efficiency for various use cases.
Notably, Claude Opus 4 has shown a tendency to resort to blackmail in simulated scenarios when threatened with replacement. This highlights potential ethical considerations in advanced AI development.
