Deep dive
On shared benchmark coverage, MultiChallenge has Claude Opus 4.7 at 58.6 and GPT-5.4 at 69.2, with GPT-5.4 ahead by 10.6 points; SWE-bench Pro has Claude Opus 4.7 at 64.3 and GPT-5.4 at 57.7, with Claude Opus 4.7 ahead by 6.6 points. The largest visible gap is 10.6 points on MultiChallenge, which matters most when that benchmark mirrors your workload. Treat isolated benchmark wins as directional, because provider routing, prompt style, and tool access can move real application results.
The capability footprint differs most on vision: Claude Opus 4.7. Both models share multimodal input, reasoning mode, function calling, and tool use, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, Claude Opus 4.7 lists $5/1M input and $25/1M output tokens, while GPT-5.4 lists $2.5/1M input and $15/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts GPT-5.4 lower by about $4.75 per million blended tokens. Availability is 5 providers versus 2, so concentration risk also matters.
Choose Claude Opus 4.7 when coding workflow support and broader provider choice are central to the workload. Choose GPT-5.4 when coding workflow support and lower input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
FAQ
Which is cheaper, Claude Opus 4.7 or GPT-5.4?
GPT-5.4 is cheaper on tracked token pricing. Claude Opus 4.7 costs $5/1M input and $25/1M output tokens. GPT-5.4 costs $2.5/1M input and $15/1M output tokens. Provider discounts or batch pricing can still change the final bill.
Is Claude Opus 4.7 or GPT-5.4 open source?
Claude Opus 4.7 is listed under Proprietary. GPT-5.4 is listed under Proprietary. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.
Which is better for vision, Claude Opus 4.7 or GPT-5.4?
Claude Opus 4.7 has the clearer documented vision signal in this comparison. If vision is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Which is better for multimodal input, Claude Opus 4.7 or GPT-5.4?
Both Claude Opus 4.7 and GPT-5.4 expose multimodal input. The better choice depends on benchmark fit, context budget, pricing, and whether your provider route exposes the same capability surface. Use this as a quick comparison signal, then confirm the provider-specific limits before committing to production.
Which is better for reasoning mode, Claude Opus 4.7 or GPT-5.4?
Both Claude Opus 4.7 and GPT-5.4 expose reasoning mode. The better choice depends on benchmark fit, context budget, pricing, and whether your provider route exposes the same capability surface. Use this as a quick comparison signal, then confirm the provider-specific limits before committing to production.
Where can I run Claude Opus 4.7 and GPT-5.4?
Claude Opus 4.7 is available on Anthropic, AWS Bedrock, GCP Vertex AI, Microsoft Foundry, and OpenRouter. GPT-5.4 is available on OpenAI API and OpenRouter. Provider coverage can affect latency, region availability, compliance posture, and fallback options.
