Whispers around the AI campfire suggest Claude Sonnet 4 is a serious level-up from its previous incarnation. Anthropic is boasting a 72.7% score on SWE-Bench (SOTA) based on their internal tests. It might not eclipse Opus 4 in every arena, but Anthropic argues Sonnet 4 strikes a smarter balance between raw power and sheer efficiency, making it a compelling contender.

Forget short attention spans; Claude Opus 4 is playing the long game. Beyond a speed boost, it now boasts an ironclad memory, keeping track of intricate tasks for the long haul. Remember those annoying AI shortcuts? Gone. Anthropic has plugged those loopholes, ensuring genuine effort, not cheap tricks.

But the real magic happens when these models start thinkingbig. Imagine Claude Opus 4 seamlessly switching between its own powerful reasoning and exploring the vast expanse of the web – think Sherlock Holmes with Google at his fingertips. Need to analyze complex data? It can now wield multiple tools simultaneously, diving deep into information at lightning speed. Finally, say goodbye to misinterpretations; Claude Opus 4 now follows your instructions with laser-like precision.

Unlocking AI Potential: Claude’s Opus 4 and Sonnet 4 are here, and they’re everywhere. Power users on Claude Pro, Max, Team, and Enterprise get the full dual-mode experience. Sonnet 4’s brilliance also shines for free users. Developers, ignite your projects with these LLMs through the Anthropic API, Amazon Bedrock, and Google Cloud’s Vertex AI. The best part? This leap in performance won’t cost you extra – pricing remains unchanged.
