Claude Opus 4.6 vs GPT-5 Pro
A side-by-side comparison of two multimodal models — real specs, pricing, strengths and weaknesses, and a clear verdict on which to choose. Kept current by our agents.
Quick verdict: which should you choose?
Choose Claude Opus 4.6 if you need
- ✓Need nuanced reasoning tasks with a known 52.9 intelligence index and high-quality structured outputs
- ✓Require up to 1M-token context at the lower $25 per million tokens price point
- ✓Prefer safety-aligned and careful responses on complex queries
- ✓Value documented output speed of 40.23 tokens per second
Choose GPT-5 Pro if you need
- ✓Handle integrated text, image, and file data in document-heavy workflows
- ✓Need flexible reasoning over large multimodal inputs despite higher cost
- ✓Work with very large inputs across modalities where integration is key
- ✓Accept variable performance on specialized topics for broader modality support
Verdict
Claude Opus 4.6 leads on measurable efficiency with a 52.9 intelligence index, 40.23 t/s speed, $25/M price, and 1M-token context, suiting nuanced reasoning and large single inputs. GPT-5 Pro leads on explicit multimodal integration of text, image, and file data for document workflows despite its higher $120/M cost and smaller 400k context. The choice hinges on whether structured reasoning at lower cost or cross-modal flexibility matters more.

Detailed analysis
Pricing
Winner: Claude Opus 4.6Claude Opus 4.6 costs $25 per million tokens while GPT-5 Pro costs $120 per million tokens. This makes Claude substantially more affordable for high-volume use. Both are proprietary closed models with no other pricing details provided.
Context Window
Winner: Claude Opus 4.6Claude Opus 4.6 offers a 1,000,000-token context compared to GPT-5 Pro's 400,000 tokens. Claude's larger window directly supports its strength in effective handling of large inputs. GPT-5 Pro notes higher computational cost at its maximum context.
Multimodal Integration
Winner: GPT-5 ProGPT-5 Pro explicitly lists strong integration of text, image, and file data plus suitability for document-heavy workflows. Claude Opus 4.6 emphasizes effective handling of large inputs and high-quality outputs but does not detail cross-modality integration. Both are categorized as multimodal.
Intelligence & Speed
Winner: Claude Opus 4.6Claude Opus 4.6 provides a 52.9 intelligence index and 40.23 t/s output speed. GPT-5 Pro has no intelligence index or speed figures listed. Claude's strengths include strong nuanced reasoning performance while its limitations note slower times on complex queries.
Claude Opus 4.6
Pros
