Anthropic launches Opus 5, matching Fable 5 performance at half the price · 10 sources tracked

Anthropic has released its new AI model, Claude Opus 5, which offers performance comparable to its more advanced Fable 5 model but at half the cost. This new model is designed for everyday business needs, including coding and knowledge work, and features a user-selectable cost-vs-capability toggle. While Opus 5 demonstrates iterative performance improvements over its predecessor, Opus 4.8, and rivals like OpenAI's GPT-5.6 "Sol," it does not represent a radical leap in capabilities, particularly in specialized areas like cybersecurity, where it has stronger safeguards than Opus 4.8 but lags behind models like Fable 5 and Mythos 5. AI

IMPACT Sets a new price-performance benchmark for enterprise AI, potentially accelerating adoption for everyday tasks.
