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-5.2 if you need
- ✓Choose GPT-5.2 if you need lower output pricing at $14 per 1M tokens for cost-sensitive multimodal tasks.
- ✓Choose GPT-5.2 if you need a documented intelligence_index of 38 alongside 400k context for document analysis.
- ✓Choose GPT-5.2 if you need unified processing of files, images, and text without maximum-length latency concerns.
- ✓Choose GPT-5.2 if you need scalable document-level analysis within a 400,000-token window.
Choose GPT-5.4 Pro if you need
- ✓Choose GPT-5.4 Pro if you need the largest context window at 1,050,000 tokens for very large inputs.
- ✓Choose GPT-5.4 Pro if you need advanced reasoning over extended multimodal contexts across text, image, and files.
- ✓Choose GPT-5.4 Pro if you need strong integration of text, image, and file data in a single proprietary model.
- ✓Choose GPT-5.4 Pro if you need versatile handling of document and visual tasks at maximum input scales.
Verdict
GPT-5.2 leads on price at $14 per 1M tokens versus GPT-5.4 Pro at $180, while GPT-5.4 Pro offers a larger 1,050,000-token context window compared to GPT-5.2's 400,000. Both models share identical multimodal support for text, images, and files from OpenAI with no native audio or video. GPT-5.2 provides a known intelligence_index of 38 where GPT-5.4 Pro's is unreported.

Detailed analysis
Pricing
Winner: GPT-5.2GPT-5.2 is listed at $14 per 1M output tokens while GPT-5.4 Pro is listed at $180 per 1M. This makes GPT-5.2 the clear lower-cost option for equivalent multimodal file, image, and text workloads.
Context Window
Winner: GPT-5.4 ProGPT-5.4 Pro provides a 1,050,000-token context versus GPT-5.2's 400,000 tokens. The larger window directly supports the model's listed strength in handling very large inputs across modalities.
Multimodal Capabilities
Winner: TieBoth models are described as supporting files, images, and text with unified processing and no native audio or video. GPT-5.2 emphasizes scalable document-level analysis while GPT-5.4 Pro emphasizes advanced reasoning over extended contexts.
Intelligence Metrics
Winner: GPT-5.2Only GPT-5.2 reports an intelligence_index value of 38; GPT-5.4 Pro leaves this field unreported. All other parameters such as speed and parameter count remain unknown for both models.
GPT-5.2
Pros
- +Extensive context window
- +Support for files, images, and text
- +Unified multimodal processing
Cons
- –High resource use with maximum context
- –No native audio or video modalities
- –Risk of diluted focus in very long inputs
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-5.2 vs GPT-5.4 Pro
Select GPT-5.2 when budget and a known intelligence score matter most within a 400k context. Select GPT-5.4 Pro when maximum context length and extended multimodal reasoning are required despite the higher price. Both remain proprietary OpenAI offerings with identical modality limitations.
