Anthropic's Opus 5 is about token efficiency, not a capability leap

Ars Technica 1 month ago 12 17 sources

Anthropic released Opus 5, an updated language model focused on cost efficiency rather than major capability gains. The model performs at roughly the same level as Anthropic's Fable on coding benchmarks while costing approximately half as much, and shows only iterative improvements over Opus 4.8. Opus 5 deliberately lacks some cybersecurity training and drops certain safety policies, positioning it as a practical middle ground for developers prioritizing affordability over cutting-edge performance.

Introducing Claude Opus 5

Anthropic released Claude Opus 5, a model that matches the intelligence of its more expensive Fable 5 counterpart while costing half as much. Opus 5 achieves state-of-the-art performance on Frontier-Bench and GDPval-AA benchmarks, and on ARC-AGI 3 scores three times higher than the next-best model. The model becomes Anthropic's default offering on Claude Max and Claude Pro, expanding access to high-capability AI for coding, research, and business automation tasks.

Anthropic’s Opus 5 is almost Fable 5

The New Stack 1 month ago 40 17 sources

Anthropic released Opus 5, a model that matches Fable 5's performance on many benchmarks while costing half as much, with pricing unchanged at $5/$25 per million tokens. On knowledge work benchmarks like GDPval-AA v2, Opus 5 scores 1861 compared to Fable 5's 1747, and it achieves double the pass rate of competing models on AutomationBench business workflow tasks. Opus 5 becomes the default model for Claude Max subscribers and shifts Fable 5's position as the company's tier for only the most demanding long-running autonomous projects.

Anthropic launches Opus 5

TechCrunch 1 month ago 10 17 sources

Anthropic released Opus 5, a model smaller than its Fable 5 but cheaper and less restrictive while outperforming Fable 5 on several benchmarks. The model launched two months after Opus 4.8, and Anthropic reports its safety classifiers will engage 85% less often for Opus 5 than for Fable 5. Users now have access to a model with fewer restrictions and a new Automatic Fallbacks feature that routes blocked requests to a weaker model instead of returning an error.

Get started with OpenAI GPT-5.6 Sol, Terra, and Luna on Amazon Bedrock

AWS 1 month ago 46

OpenAI's GPT-5.6 Sol, Terra, and Luna models are now available on Amazon Bedrock, offering developers access to frontier models through familiar APIs with AWS security and regional processing. The three models are priced at OpenAI's first-party rates and available in select US regions, with Sol optimized for reasoning, Terra for general production work, and Luna for fast, low-cost inference. Users can access these models through the bedrock-mantle endpoint using OpenAI SDKs, and benefit from prompt caching that reduces costs by 90% for repeated context processing.

Anthropic releases Opus 5 with ‘close’ to Fable 5’s capabilities

The Verge 1 month ago 34 17 sources

Anthropic released Claude Opus 5, a new model that the company claims achieves capabilities close to Claude Fable 5 in many domains and shows significant improvements in complex coding tasks. Opus 5 arrives weeks after government scrutiny of Fable 5 led to a temporary takedown and the implementation of stronger cybersecurity measures. The release represents Anthropic's effort to provide a capable alternative following regulatory concerns about its most advanced model.
