The following comment was made by an LLM, it may be inaccurate: Based on my search, I found two potentially related PRs that address similar issues with message normalization and content filtering:
These PRs appear to address related concerns around message content filtering and handling Claude/Anthropic model compatibility, though they may be focused on different specific scenarios (thinking/reasoning blocks vs. whitespace-only blocks). |

What does this PR do?
When using Anthropic models through non-standard provider configurations (e.g.Github Copilot), the existing check model.api.npm === "@ai-sdk/anthropic" fails to detect them as Anthropic. This causes whitespace-only or empty text blocks to be sent to the API, which Anthropic rejects.
This PR:
Should fix #2655
How did you verify your code works?
Manually test, verified I can continue with Claude model after a tool call cancel somehow insert an empty text block to request.
