Decision reading

Claude Opus 4.7 (Adaptive) has the higher public score, 72.25 versus 49.27, and the 90% score intervals do not overlap.

8 results are shared. Category rows based on different benchmark sets are marked directional and do not name a winner.

Which one for your work

Recommendations appear only when a shared evidence basis or an explicit operating constraint supports the call. Secondary and unsupported use cases stay disclosed below the initial list.

  • Coding work

    Code generation, repair, and software-engineering tasks

    Claude Opus 4.7 (Adaptive)

    Claude Opus 4.7 (Adaptive) leads on the same 2 weighted benchmark rows.

    Confidence: limited

  • Long documents

    Claude Opus 4.7 (Adaptive)

    Claude Opus 4.7 (Adaptive) has the larger documented context window.

    Confidence: documented

  • Agentic work

    Tool use, computer use, and multi-step task completion

    Not enough matched evidence

    The category averages use different weighted benchmark sets, so they are directional rather than like-for-like.

    Not enough matched evidence

    A complete comparable API-rate estimate is not available for both models.

    Confidence: rate-fallback

What is actually comparable

Shared results can support a head-to-head reading. Results present for only one model describe coverage, not superiority.

1 category uses different evidence sets. Those rows remain visible for coverage context but do not name a winner.

Category results, on a stated basis

Each row states whether both averages use the same weighted benchmark set. Directional and not-comparable rows remain visible, but they never receive a winner in this template.

Shape of the matched evidence

Only shared public evidence is shown. Sparse evidence stays a ruled list rather than being closed into a radar shape.

Too few matched category axes support a radar. The ruled list below shows only shared benchmark results; positions use each benchmark’s normalized display scale when available.

What each workload costs

Three fixed token mixes turn per-token rates into comparable decisions. Each scenario states context fit and whether cached input had to fall back to the published list-input rate.

Frequently asked questions

Which is better, Claude Opus 4.7 (Adaptive) or Ornith-1.5-35B-A3B?

Claude Opus 4.7 (Adaptive) has the higher public score, 72.25 versus 49.27, and the 90% score intervals do not overlap. That is the clearest overall quality signal in the current public data.

Which is better for coding, Claude Opus 4.7 (Adaptive) or Ornith-1.5-35B-A3B?

Claude Opus 4.7 (Adaptive) leads the like-for-like coding comparison across 2 shared weighted benchmark rows.

Which is better for agentic tasks, Claude Opus 4.7 (Adaptive) or Ornith-1.5-35B-A3B?

The current agentic tasks averages use different weighted benchmark sets, so BenchLM does not name a winner from them. Read the shared benchmark rows directly and test the models on the same task set.

Which costs less, Claude Opus 4.7 (Adaptive) or Ornith-1.5-35B-A3B?

Both models do not have comparable published API token rates, so this page does not name a universal price winner.

Which has the larger context window, Claude Opus 4.7 (Adaptive) or Ornith-1.5-35B-A3B?

Claude Opus 4.7 (Adaptive) has the larger documented context window: 1M, compared with 262K.
