Anthropic releases Opus 5.5 with lower prices and Fable-level performance
What's happening
Anthropic has released Opus 5.5, which the company called "the strongest-performing model we've tested to date." Multiple community analyses show Opus 5.5 winning top spots: ArtificialAnalysis.ai and user tests report it dominates on three performance metrics and matches Fable 5.1 on high-effort tasks while costing $1.82 versus $7.63. Other community posts say Opus 5.5 beats Fable 5.1 across benchmarks, outperforms GPT-6 Astra on medium-effort agentic coding while being about 80% cheaper, and is about 30% faster than Opus 5. Anthropic also lowered prices and raised usage limits for users, including a credited reset described as a "tibo style banked reset."
Why it's trending
This is rising because Opus 5.5 combines top-ranked performance with materially lower cost and higher throughput, changing the cost/quality tradeoffs creators and teams care about now.

Anthropic's release of Opus 5.5 today sent me down a rabbit hole. I wanted to understand the best effort levels for using this new best-in-class model. That led me to the below, based on Artificial Analysis Intelligence Index v4.3.2 scores. If you look at the first chart, you'll see that in this index Opus 5.5 gets smarter as you dial up the effort level. (That's the result for this scoring model,
