Claude’s most advanced models for coding and knowledge work. Their research capabilities also offer an early glimpse of how AI models will contribute to scientific progress.
Anthropic has shipped a lot of models, but this one reads like a direct response to what builders kept asking for: better results on long, agentic work, real answers on price and data retention, and safeguards that get out of the way for legitimate use.
Cache reads got cheaper, so typical workloads cost about 25% less than Fable 5, and highly agentic runs can save up to 45%. Pair that with Low and Medium effort modes that match or beat Fable 5 output, and you're getting more model for less money.
Cybersecurity false positives are down 60% too, which anyone who has hit a wall mid-task will appreciate.
It's also live day one across the major AI gateways, including Netlify's, so you can drop it into an existing stack without touching your keys or config.

The knowledge-work angle caught my attention. Handling analysis, research, and coding in the same workflow could be quite useful.
Does the model perform better when working through long research tasks with multiple sources?
Coding benchmarks are useful, but I’m more interested in how it performs on messy real world projects where the requirements keep changing.
I like seeing more attention on scientific and research workflows. That’s an area where stronger models could be genuinely useful.
The pricing change is the interesting part. Better models are great until you actually run agents all day and see the bill 😅 Curious how well Medium effort holds up on long coding tasks vs fable 5
@thisiskp_ Love Fable, the example is really terrific !

Hey PH community 👋
Excited to hunt Claude Fable 5.1 today!

Here's a terrific example of what it can do. Alex gave it a picture of a property lot. It designed a house for the lot, rendered it, and produced a cinematic walkthrough 🤯
The pricing move is what stands out to me.
