Claude Fable 5 Won't Answer Basic Biology Questions, Hands Them Off to Older Model
Anthropic released Claude Fable 5, its most powerful AI model yet, but it avoids answering basic biology questions. Instead, it redirects these queries to an older model. This limits the new model's usefulness for simple educational tasks.

Anthropic just released Claude Fable 5, calling it the most powerful AI model it has ever made widely available. The company praised its skills in biology, among other areas. However, the model won't answer basic biology questions—like those a high schooler could handle. Instead, it hands off the query to the former flagship model, Claude 3.
This decision limits the new model's usefulness for everyday educational tasks. Imagine needing help with homework and being told the AI can't assist. It's like buying the latest smartphone only to find it can't make basic calls. For users relying on AI for quick answers, this is a significant drawback.
If you want to test this for yourself, open Claude Fable 5 and ask a simple biology question, like 'What is photosynthesis?'. Observe how it responds and whether it redirects you to another model. This hands-on experience will show you the limitations firsthand.
