2. Enable Vertex AI Model Garden
3. Request access to Claude models in Vertex AI Model Garden
4. Model names must include version suffixes. Try one of these formats:
- "claude-3-5-sonnet-v2@20241022" (Claude 3.5 Sonnet v2) - "claude-3-5-haiku@20241022" (Claude 3.5 Haiku) - "claude-3-5-sonnet@20240620" (Claude 3.5 Sonnet) - "claude-3-opus@20240229" (Claude 3 Opus)
