Our composite score (0–100) combines six weighted signals: benchmark performance (25%), pricing efficiency (25%), context window size (15%), model recency (15%), output capacity (10%), and capability versatility (10%). Here's what the scores mean for these two models:
Scores 89/100 (rank #28), placing it in the top 91% of all 290 models tracked.
Scores 97/100 (rank #2), placing it in the top 100% of all 290 models tracked.
GPT-5.4 has a 8-point advantage, which typically translates to noticeably better performance on complex reasoning, code generation, and multi-step tasks.
Gemini 3.1 Pro Preview Custom Tools offers 20% better value per quality point. At 1M tokens/day, you'd spend $210.00/month with Gemini 3.1 Pro Preview Custom Tools vs $262.50/month with GPT-5.4 — a $52.50 monthly difference.
Both models have comparable response speeds. For most applications, the latency difference is negligible.
When latency matters most: Interactive chatbots, IDE code completion, real-time translation, and user-facing applications where response time directly impacts experience. For batch processing, background summarization, or offline analysis, latency is less critical.
Code generation & review
Higher benchmark score (0/100) indicates stronger performance on coding tasks like generating functions, debugging, and refactoring
Customer support chatbot
Faster response time (speed score 0/100) is critical for user-facing chat. Gemini 3.1 Pro Preview Custom Tools also offers lower per-token costs for high-volume support
Long document analysis
Larger context window (1050K tokens) can process longer documents, contracts, and research papers in a single pass
Batch data extraction
Lower output pricing ($12.00/M) reduces costs when processing thousands of records daily
Creative writing & content
Higher overall composite score (97/100) correlates with better nuance, coherence, and style in long-form content
Image understanding & OCR
Supports vision input — can analyze screenshots, diagrams, photos, and scanned documents directly
GPT-5.4 has a moderate advantage with a 8.200000000000003-point lead in composite score. It wins on more signal dimensions, but Gemini 3.1 Pro Preview Custom Tools has specific strengths that could make it the better choice for certain workflows.
