Efiwe 1.5 is 1.4 MB in download size. The smallest of the ten external language models you can now download on Efiwe is 105 MB, and the largest is 1.1 GB. That size gap explains almost everything about how the two kinds of model share the work. On October 12, 2026, we added ten external small language models (SLMs) that run on your phone: SmolLM2 135M, LFM2 350M, Gemma 3 270M compact, SmolLM2 360M, Gemma 3 270M, LFM2 700M, Qwen 2.5 0.5B, LFM2 1.2B, Gemma 3 1B and Qwen 2.5 1.5B. They write fuller, friendlier explanations. Efiwe 1.5 still grades your code offline and whenever an on-device model is selected, and it still works out what is wrong with it, across all eight courses: HTML, CSS, JavaScript, Tailwind, Python, PHP, SQL and Prompt Engineering. This article explains why, and how to pick the right setup for your phone.
