GPT-5 vs GPT-5.4 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 GPT-5 if you need
- ✓Choose GPT-5 if you need a known output speed of 167.38 t/s and $10/M pricing.
- ✓Choose GPT-5 if you need native multimodal input support with seamless text-image-file integration.
- ✓Choose GPT-5 if you need a verified intelligence index of 15.3 alongside a 400k context window.
- ✓Choose GPT-5 if you want to avoid unverified performance metrics and high per-token costs.
Choose GPT-5.4 Pro if you need
- ✓Choose GPT-5.4 Pro if you need a 1.05M-token context for very large multimodal inputs.
- ✓Choose GPT-5.4 Pro if you need advanced reasoning over extended contexts beyond 400k tokens.
- ✓Choose GPT-5.4 Pro if your tasks involve document-scale text, image, and file integration at maximum length.
- ✓Choose GPT-5.4 Pro if versatility across very large inputs outweighs unknown speed and 18x higher price.
Verdict
GPT-5 leads on verified speed, dramatically lower price, and native multimodal integration, while GPT-5.4 Pro leads on raw context size and extended-context reasoning. GPT-5 offers concrete, measurable advantages for most multimodal workloads; GPT-5.4 Pro only pulls ahead when inputs exceed 400k tokens. Overall, GPT-5 is the stronger factual choice unless maximum context length is the sole priority.

Detailed analysis
Context Window
Winner: GPT-5.4 ProGPT-5.4 Pro provides a 1,050,000-token context versus GPT-5's 400,000 tokens. This gives GPT-5.4 Pro a clear advantage for very large inputs. GPT-5's context is still large but smaller by more than half.
Pricing
Winner: GPT-5GPT-5 is priced at $10 per million tokens while GPT-5.4 Pro costs $180 per million tokens. GPT-5 is therefore 18 times cheaper on output. No other cost data is provided for either model.
Speed & Performance
Winner: GPT-5GPT-5 reports a concrete output speed of 167.38 tokens per second and an intelligence index of 15.3. GPT-5.4 Pro lists neither metric. GPT-5 therefore supplies the only verifiable speed and intelligence numbers.
Multimodal Capabilities
Winner: GPT-5GPT-5 explicitly lists native multimodal input support and seamless text-image-file integration. GPT-5.4 Pro emphasizes handling large inputs across modalities but notes the absence of native audio or video support. Both handle text, image, and file data, yet GPT-5's native support is stated more directly.
GPT-5
Pros
- +Very large context window
- +Native multimodal input support
- +Seamless text-image-file integration
Cons
- –Hypothetical model with unverified performance
- –High resource demands for maximum context
- –Potential latency on large multimodal tasks
GPT-5.4 Pro
Pros
- +Handles very large inputs across modalities
- +Strong integration of text, image, and file data
- +Advanced reasoning over extended contexts
Cons
- –Higher latency on maximum-length inputs
- –No native audio or video support
- –Proprietary access with usage constraints
Summary: GPT-5 vs GPT-5.4 Pro
Select GPT-5 when speed, price, and confirmed multimodal integration matter most. Choose GPT-5.4 Pro only when the 1.05M context window is required for maximum-length tasks. In all other measured dimensions the provided facts favor GPT-5.
