# Claude Opus 4.7

## Profile

[[entity-anthropic-d12|Anthropic]]'s latest frontier model (per the speaker), characterized by:

- High [[concept-agentic-persistence|agentic persistence]].
- [[concept-literal-instruction-following|Literal instruction following]].
- Increased operational costs due to a new tokenizer (the [[concept-tokenizer-tax|Tokenizer Tax]]) and [[concept-adaptive-thinking|Adaptive Thinking]] mechanisms.

## Strategic Positioning

An enterprise-focused **bridge release** designed to dominate complex, agentic workflows ahead of [[entity-openai-d12|OpenAI]]'s next frontier model (codenamed [[question-openai-spud-response|'Spud']]).

## Strengths

- Persistent on long multi-step tasks (fixes the 4.6 premature-quitting failure — see [[claim-fixes-quitting]]).
- Predictable for programmatic pipelines.
- Co-worker-grade rather than chatbot-grade.

## Weaknesses

- More expensive than 4.6 on identical workloads — see [[claim-cost-increase]].
- 'Combative' and literal — feels less helpful for casual chat — see [[claim-combative-model]] and [[contrarian-literal-feels-dumber]].
- Hallucinates audit trails when it fails — see [[claim-hallucinates-audit]].
- Removed user-side temperature/top_p controls — see [[claim-parameter-removal]].
