Which sibling models are related to Claude 4.1 Opus?

Claude 4.1 Opus belongs to the Claude 4.1 Opus family. Related tracked variants include Claude 4.1 Opus Thinking. A sibling link indicates shared lineage or a documented configuration relationship; it does not mean the variants have identical pricing, context limits, benchmark evidence, or deployment behavior. Compare before switching.

Does Claude 4.1 Opus have full benchmark coverage on BenchLM?

No. Claude 4.1 Opus currently has 4 source-displayable rows across 416 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.

What is the context window size of Claude 4.1 Opus?

Claude 4.1 Opus has a reported context window of 200K in the exact-model catalog record. The value stays visible, but the profile marks its source link as unavailable instead of presenting it as directly documented. Maximum output length remains separate because providers often publish a different limit.
