title: 'Field Guide to Fable — Thariq Shihipar, Anthropic'
description: >-
  Ask a chat model which Pokemon names end in aw and it fails, even though it
  knows every Pokemon by heart. Ask Claude Code and it writes a script, fetches
  the list, and filters for the answer in seconds. Thariq Shihipar, who works on
  Claude Code at Anthropic, calls that gap capability overhang: models get
  smarter in spiky ways, and the tools you give them decide which spikes you can
  reach. Thariq covers what it takes to work with Fable, Anthropic's newest
  model. Claude Code cut 80 percent of its system prompt, since heavy
  instructions now constrain a model more imaginative than the examples it's
  given. The ask user question tool went from barely working under Opus 4 to
  generating embedded HTML questionnaires under Fable. He built a full keynote
  deck in four hours with it, and argues teams should stop picking two of good,
  fast, and cheap and start demanding all three. Speaker info: -

# Field Guide to Fable — Thariq Shihipar, Anthropic

Ask a chat model which Pokemon names end in aw and it fails, even though it knows every Pokemon by heart. Ask Claude Code and it writes a script, fetches the list, and filters for the answer in seconds. Thariq Shihipar, who works on Claude Code at Anthropic, calls that gap capability overhang: models get smarter in spiky ways, and the tools you give them decide which spikes you can reach. Thariq covers what it takes to work with Fable, Anthropic's newest model. Claude Code cut 80 percent of its system prompt, since heavy instructions now constrain a model more imaginative than the examples it's given. The ask user question tool went from barely working under Opus 4 to generating embedded HTML questionnaires under Fable. He built a full keynote deck in four hours with it, and argues teams should stop picking two of good, fast, and cheap and start demanding all three.
