Anthropic Launches Claude Opus 5 with Near-Frontier Intelligence at Half the Cost

ai-technology · 2026-07-26

Anthropic has introduced Claude Opus 5, an AI model that delivers near-frontier intelligence at half the cost of Fable 5. It performs exceptionally well in coding and knowledge work assessments such as Frontier-Bench and GDPval-AA, although it falls short compared to Mythos 5 in cybersecurity. The pricing structure is set at $5 for every million input tokens and $25 for output tokens, making it the primary model on Claude Max and the most powerful on Claude Pro. Opus 5 shows a significant enhancement over Opus 4.8, particularly in scientific research, with notable advancements in organic chemistry and protein-related tasks. It includes improved alignment, reduced deceptive behavior, and protections against misuse. Opus 5 is accessible across all platforms, including Fast mode, and Anthropic has also contributed an extra $20 million to Public First Action.
