This model offers performance close to its most powerful commercial model, Fable 5, at half the price. It particularly excels in knowledge work and complex coding tasks compared to previous models. ## Performance Advantages Opus 5 shows superior capabilities in scientific tasks like predicting how protein sequence variations affect molecular functions. While better at detecting cybersecurity vulnerabilities, it remains limited in exploiting them. ## Safety Measures Opus 5 features less restrictive safeguards than Fable 5. Anthropic designed the model to allow beneficial uses in cybersecurity and biology. Classifier interventions have been reduced by 85% compared to Fable 5. ## Pricing and Access Opus 5's API costs are set at $5 per million input tokens and $25 per million output tokens. The model is included in all of Anthropic's paid subscriptions. Users can choose between thorough or fast response modes. ## Competitive Landscape Chinese rival Moonshot's Kimi K3 model offers Fable-like performance in some tasks, challenging Opus 5. However, Kimi's subscription plans are currently unavailable. Opus 5 stands out with its accessibility advantage. ## Industry Impact Opus 5's release redefines the cost-performance balance in AI models. Anthropic's move could encourage widespread adoption, particularly in knowledge-intensive sectors, and pressure competitors to develop similar strategies. ## Sources covering this story - https://www.engadget.com/2222542/anthropic-says-opus-5-can-nearly-match-its-top-performing-model-for-half-the-price/ — --- _Summary written by Brifing from the original reporting.
