Detailed analysis
Intelligence
Winner: GPT-5.4GPT-5.4 scores 51.4 on the intelligence index compared to Gemini's 25, giving it a clear advantage for tasks requiring deeper multimodal reasoning. Gemini's lower score aligns with its Lite design that trades depth for efficiency. This gap makes GPT-5.4 preferable when capability outweighs speed.
Speed
Winner: Gemini 3.1 Flash Lite PreviewGemini 3.1 Flash Lite Preview delivers 290.34 tokens per second versus GPT-5.4's 145.62 t/s, making it roughly twice as fast. Its lightweight design is explicitly optimized for speed. GPT-5.4's slower rate may increase latency on large-context inputs.
Pricing
Winner: Gemini 3.1 Flash Lite PreviewGemini costs $1.5 per million tokens while GPT-5.4 costs $15 per million, an order-of-magnitude difference. This makes Gemini far more economical for high-volume multimodal usage. Both are proprietary models from major providers.
Multimodal Capabilities
Winner: Gemini 3.1 Flash Lite PreviewGemini offers unified native support for video, audio, and files in addition to text and images. GPT-5.4 supports text, image, and file tasks but explicitly lacks native audio or video. Context windows are nearly identical at roughly 1 million tokens.
Gemini 3.1 Flash Lite Preview
Pros
- +Broad native support for multiple modalities
- +Very large context window for document and media tasks
- +Lightweight design optimized for speed
Cons
- –Preview model may show inconsistent behavior
- –Lite variant trades depth for efficiency
- –Experimental features can be less reliable than stable releases
GPT-5.4
Pros
- +Handles extremely large contexts
- +Seamless text-image-file integration
- +Strong at document-level tasks
Cons
- –No native audio or video support
- –Large context can increase latency
- –May need careful prompting for complex tasks
Summary: Gemini 3.1 Flash Lite Preview vs GPT-5.4
Select Gemini 3.1 Flash Lite Preview for speed, cost efficiency, and full audio-video multimodal support in high-throughput scenarios. Choose GPT-5.4 when maximum intelligence for complex document and reasoning tasks is the priority. The models serve different trade-off profiles rather than direct substitutes.
