Detailed analysis
Intelligence
Winner: GPT-5.2GPT-5.2 scores 38 on the intelligence index compared to Gemini 2.5 Flash Lite's 11.4. This gap favors GPT-5.2 for tasks needing deeper multimodal reasoning. Gemini's lite design explicitly trades some capability for speed.
Pricing & Speed
Winner: Gemini 2.5 Flash LiteGemini 2.5 Flash Lite costs $0.4 per 1M tokens versus GPT-5.2's $14 and delivers 269.76 tokens per second output. GPT-5.2 speed is unreported. These metrics make Gemini the clear choice for cost-sensitive or high-throughput use.
Context & Modalities
Winner: Gemini 2.5 Flash LiteGemini offers 1,048,576 context tokens against GPT-5.2's 400,000 and adds native audio and video support. GPT-5.2 covers files, images, and text only. Gemini therefore handles larger and more varied multimodal inputs.
Limitations
Winner: TieGPT-5.2 risks diluted focus at max context and lacks audio/video. Gemini 2.5 Flash Lite shows reduced depth on complex reasoning. Each model carries distinct trade-offs matching its design goals.
