**TLDR:** Anthropic doesn't provide direct FT API (not in Anthropic Console). Two workarounds: (1) **AWS Bedrock Custom** for Claude FT, (2) **Prompt caching** + few-shot prompting (no FT). Cookbook decision: for most use-cases prompt-caching + system prompt refinement suffices; for real FT use Bedrock route.
