Anthropic launches Opus 5, cheaper than Fable 5
Anthropic launched Claude Opus 5 on 2026-07-24, a new Claude-series large language model available via the Claude API that the company says delivers its best price-performance yet. Opus 5 reportedly outperforms prior models on coding and complex office/knowledge-work benchmarks (including Frontier-Bench v0.1) and produces stronger visual outputs while improving safety and deception resistance. Pricing is $5 per 1M input tokens and $25 per 1M output tokens—roughly half the token cost of the prior Fable model. A “quick mode” runs about 2.5× faster and is offered on-platform at roughly double the base price. Anthropic also announced two beta features (in-conversation tool switching without invalidating prompt cache, and automatic API fallbacks for requests flagged by safety classifiers). The company cautions Opus 5 is not state-of-the-art for risky dual-use capabilities; it briefly restricted Mythos 5/Fable 5 for export-control compliance and continues government pre-deployment testing.
A major model release that reduces inference pricing could accelerate enterprise AI adoption and put pricing pressure on competitors, but it is not a platform-level policy or earnings event—moderate industry impact.

Anthropic launches Opus 5 model
Anthropic announced Opus 5, a new heavyweight model released July 24, 2026. Opus 5 is described as smaller, cheaper and less restrictive than the company's Fable 5 model while outperforming Fable 5 on several announced benchmarks. The model is not subject to the 30-day data retention policy that covers Fable and Mythos. Anthropic says safety classifiers will engage less often for Opus 5 and is introducing an opt-in beta called Automatic Fallbacks to route requests to a less powerful model when safety checks trigger, providing functional responses instead of errors. Opus 5 retains safeguards around cybersecurity tasks such as exploit generation and binary scanning.
Anthropic Launches Claude Fable 5.1 with Top AI Benchmarks
Anthropic launched Claude Fable 5.1 and its sibling Claude Mythos 5.1, showcasing improved performance in coding and knowledge work. Fable 5.1 achieved a record 66 on the Artificial Analysis Intelligence Index at maximum reasoning effort, surpassing previous top models. Anthropic slashed cache read prices by 75% to $0.25 per million tokens, claiming potential savings of up to 45% for agentic workloads, though actual per-task costs may rise due to higher token use. The models are available via the Claude API and major clouds including AWS, Google Cloud, and Microsoft Azure. Enterprise Frontier Safeguards enable customers to retain data in their own cloud with zero data retention, and invisible watermarking ensures compliance with the EU AI Act. Pro subscribers must pay extra for Fable 5.1, with Opus 5 remaining the best bundled option.
Anthropic Releases Claude Fable 5 Publicly
Anthropic publicly released Claude Fable 5 (a guarded variant of its Mythos-class model) on 2026-06-09, making the most powerful Mythos capabilities available to consumers, SMBs and enterprise customers with safety restrictions. Fable 5 is positioned for software development, knowledge work and vision tasks; it defers high-risk queries in cybersecurity, biology and chemistry to the predecessor Claude Opus 4.8. Anthropic offered early access to Mythos under Project Glasswing to select tech and finance firms and is also providing a less-restricted Mythos 5 to preapproved organizations. Fable 5 is available via the Claude API and consumption-based Enterprise plans; Pro/Max/Team/Enterprise subscribers could use it free until 22 June 2026, after which usage credits are required. Pricing is $10 per million input tokens and $50 per million output tokens (about twice the cost of Opus 4.8).
