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 55/100 (rank #248), placing it in the top 15% of all 290 models tracked.
Scores 83/100 (rank #52), placing it in the top 82% of all 290 models tracked.
Grok 4 Fast has a 28-point advantage, which typically translates to noticeably stronger performance on complex reasoning, code generation, and multi-step tasks.
Granite 4.0 Micro offers 82% better value per quality point. At 1M tokens/day, you'd spend $1.90/month with Granite 4.0 Micro vs $10.50/month with Grok 4 Fast - a $8.60 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. Granite 4.0 Micro also offers lower per-token costs for high-volume support
Long document analysis
Larger context window (2000K tokens) can process longer documents, contracts, and research papers in a single pass
Batch data extraction
Lower output pricing ($0.11/M) reduces costs when processing thousands of records daily
Creative writing & content
Higher overall composite score (83/100) 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
Grok 4 Fast clearly outperforms Granite 4.0 Micro with a significant 28.300000000000004-point lead. For most general use cases, Grok 4 Fast is the stronger choice. However, Granite 4.0 Micro may still excel in niche scenarios.
