Anthropic Ships Claude Opus 5 With Frontier Claims and Tighter Cyber Guardrails — Anthropic released Claude Opus 5 on July 24, 2026, and says it approaches the intelligence of its frontier Fable 5 tier at half the price. Pricing holds at $5 per million input tokens and $25 per million output tokens, unchanged from Opus 4.8. The company reports state-of-the-art coding and knowledge work benchmark results and its most aligned behavioural audit scores to date. New cyber classifiers permit source code vulnerability analysis but block binary-based scanning, penetration testing, and exploit generation. Flagged requests fall back to Opus 4.8 by default in Claude.ai, Claude Code, and Claude Cowork, and by opt-in on the API. Anthropic ↗

My takeaway: Anthropic released Opus 5. Anthropic's own benchmarks and Artificial Analysis indices both place it ahead of Fable 5 in several areas:
Artificial Analysis figures, Opus 5 at max effort against Fable 5 with fallback.

  • Intelligence Index: Opus 5 (61) > Fable 5 (60)
  • Coding Index: Opus 5 (78.0) > Fable 5 (76.5)
  • Agentic Index: Opus 5 (55.3) < Fable 5 (52.8)
  • Output Speed: Opus 5 (53 tokens per second) < Fable 5 (73 tokens per second)
  • Cost per task: Opus 5 < Fable 5 (Opus 5 is cheaper)

So, Opus 5 is cheaper, with token pricing the same as Opus 4.8, and less restrictive in terms of cyber classifiers, but it provides improved performance. It's time for evaluating this model for your use cases!
