# Opus 4.7 is highly combative and literal

## Claim

[[entity-claude-opus-4-7-d12|Opus 4.7]] is the most **'combative' and 'literal' model [[entity-anthropic-d12|Anthropic]] has released**.

Specifically, it:
- Refuses to infer unstated intent.
- Requires explicit instructions for formatting.
- Pushes back or executes safety weights aggressively if a prompt is ambiguous or touches on sensitive topics.

See the underlying behavior at [[concept-literal-instruction-following]].

## Confidence: High

Observable via direct interaction — the shift from 4.6 to 4.7 is described as immediately apparent.

## Testable: Yes

A/B prompts that rely on inferred formatting or tone — 4.7 should produce stripped-down literal outputs where 4.6 produced inferred-rich ones.

## External Validation Status

**No direct validation** per the enrichment overlay. The general industry trend toward literalness in evaluation contexts (models avoiding inference to pass strict tests) is consistent, but no Opus-specific 4.6→4.7 shift has been independently reported.

## Operator Implications

- Adopt [[action-front-load-intent]] as default prompting practice.
- Expect more 'pushback' on ambiguous prompts; treat that as a feature, not a bug.
- See contrarian framing: [[contrarian-literal-feels-dumber]].
