- add the claude-haiku-5-5 model ID to @ai-sdk/anthropic and @ai-sdk/google-vertex, anthropic.claude-haiku-5-5 and us.anthropic.claude-haiku-5-5 to @ai-sdk/amazon-bedrock, and anthropic/claude-haiku-5.5 to @ai-sdk/gateway
- recognize claude-haiku-5-5 as a known model with a 128k max output token limit and all five effort levels; thinking can be disabled up to high effort, and xhigh and max are lowered to high with a warning when thinking is disabled
- claude-haiku-5-5 does not support thinking token budgets: thinking: { type: 'enabled', budgetTokens } is converted to adaptive thinking with a warning
