Anthropic Launches Claude Opus 5.5 Despite Slowdown Call

Anthropic released Claude Opus 5.5, its flagship AI model and the first in the 5.5 family, on September 22, 2026. It achieves the highest-ever score (58) on the Artificial Analysis Intelligence Index and leads six out of ten benchmarks, including outperforming OpenAI's GPT-6 Astra on Terminal-Bench 4.0. Priced at $4 per million input tokens and $20 per million output tokens (20% lower), it promises a 40% cost reduction for typical workloads, though savings depend on config. It is 30% faster, now defaults in Claude Code and the Claude app, and matches Claude Fable 5.1 on most tasks. Early tests show efficiency gains but also more concurrency issues and security test failures. Anthropic cites external safety evaluations, and OpenAI responded with GPT-6 Sol and Luna, priced ~50% lower and offering up to 90% cache discounts.

• Claude Opus 5.5 scores 58 on the Artificial Analysis Intelligence Index, the highest recorded, and leads six out of ten benchmarks.
• Pricing reduced to $4 per million input tokens, $20 per million output tokens, and cache reads at $0.20 per million tokens, promising a 40% cost reduction per task (though configuration may affect savings).
• Opus 5.5 is 30% faster, supports multi-agent scaling up to 100 parallel agents, and is now default in Claude Code and the Claude app.

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.
