âš¡ Intel Core i5 with 32GB RAM: Maximum Stability
The 32GB i5 configuration provides maximum system stability and excellent multitasking capabilities. While model capacity remains limited by the 4-core architecture, this setup offers the best overall experience for users who need reliable performance.
💡 Why We Recommend ≤10B Models for CPU Inference: While 32GB RAM can technically load larger models, CPU-only inference becomes impractically slow beyond 10B parameters. On a Core i5, larger models would generate only 1-5 tokens/second, making conversations frustrating. For larger models, a dedicated GPU is essential. With 7B-8B models, you'll enjoy responsive generation speeds that make AI interactions practical.
