Anthropic Releases Claude Opus 5.5 Model with Lower Prices and Enhanced Performance

Anthropic officially launched its new large language model, Claude Opus 5.5, marking its first major model release since CEO Dario Amodei advocated for an AI slowdown. The company announced that the updated model offers significant performance enhancements and is available at a reduced cost. Many outlets highlighted that this release comes as Anthropic prepares for its initial public offering (IPO). The new Opus 5.5 model is reported to achieve performance levels comparable to the Fable 5.1 model, while also featuring enhanced safety measures, particularly for cybersecurity queries. While some early reports, based on leaks, suggested a 20% price reduction, official reports from outlets citing Anthropic's announcement indicate a more substantial 40% decrease in cost. The company also aims to provide a less "Claudish" writing style with this iteration.
