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 96/100 (rank #12), placing it in the top 96% of all 290 models tracked.
Scores 73/100 (rank #99), placing it in the top 66% of all 290 models tracked.
GPT-5.1-Codex-Max has a 22-point advantage, which typically translates to noticeably stronger performance on complex reasoning, code generation, and multi-step tasks.
Grok 3 Mini offers 93% better value per quality point. At 1M tokens/day, you'd spend $12.00/month with Grok 3 Mini vs $168.75/month with GPT-5.1-Codex-Max — a $156.75 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. Grok 3 Mini also offers lower per-token costs for high-volume support
Long document analysis
Larger context window (400K tokens) can process longer documents, contracts, and research papers in a single pass
Batch data extraction
Lower output pricing ($0.50/M) reduces costs when processing thousands of records daily
Creative writing & content
Higher overall composite score (96/100) 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-5.1-Codex-Max clearly outperforms Grok 3 Mini with a significant 22.299999999999997-point lead. For most general use cases, GPT-5.1-Codex-Max is the stronger choice. However, Grok 3 Mini may still excel in niche scenarios.
