IBM Granite 4.2 — lokalny model AI od IBM
Autor: Jakub Rusinowski · Ostatnia aktualizacja:
IBM's first family of dense decoder-only reasoning models, released August 2026 in 3B, 8B and 30B. Granite 4.2 drops the hybrid Mamba-2 MoE design of Granite 4.0 and continues the dense line Granite 4.1 started. Each size is pretrained from scratch on roughly 15T tokens with a five-phase context extension to 512K, then RL-post-trained for tool calling, RAG, structured JSON and an explicit thinking mode. All three are Apache 2.0.
Warianty
Najmniejszy wariant IBM Granite 4.2 potrzebuje około 3 GB VRAM przy Q4_K_M — skwantyzowane wagi plus narzut frameworka, bez pamięci podręcznej KV.
| Model | VRAM przy Q4 | VRAM | Kontekst | Uruchom |
|---|---|---|---|---|
| Granite 4.2 3B → 3B | ~2.6 GB | 131,072 | ollama run granite4.2:3b | |
| Granite 4.2 8B → 8B | ~5.6 GB | 131,072 | ollama run granite4.2:8b | |
| Granite 4.2 30B → 30B | ~18.9 GB | 131,072 | ollama run granite4.2:30b |
Pamięć to skwantyzowane wagi plus narzut przy Q4_K_M, liczone tym samym silnikiem co sprawdzarka GPU i VRAM.

IBM Granite 4.2 — najczęściej zadawane pytania
How much VRAM does IBM Granite 4.2 need?
IBM Granite 4.2 needs about 3 GB VRAM at Q4_K_M quantization for its smallest variant. Variants: Granite 4.2 3B (3 GB, Q4_K_M); Granite 4.2 8B (6 GB, Q4_K_M); Granite 4.2 30B (19 GB, Q4_K_M). On Apple Silicon, unified memory counts toward this requirement.
Can I run IBM Granite 4.2 on an RTX 4090 (24 GB)?
Yes — IBM Granite 4.2 runs on an RTX 4090 (24 GB) and other 24 GB cards such as the RTX 3090. Smaller variants also fit comfortably on 8–16 GB GPUs at Q4_K_M.
What quantization should I use for IBM Granite 4.2?
Q4_K_M is the best balance of quality and VRAM for IBM Granite 4.2 in most cases. Choose Q8_0 for near-lossless quality if you have spare VRAM, or smaller quants (Q3/Q2) only when memory is tight.
How do I run IBM Granite 4.2 with Ollama?
Install Ollama, then run: ollama run granite4.2:3b. This downloads IBM Granite 4.2 and starts a local, OpenAI-compatible endpoint — no internet connection is needed after the initial download.
