Frequently Asked Questions

How much VRAM does Gemma 4 Novelist Eclipse 31B need?

Gemma 4 Novelist Eclipse 31B requires 67.0 GB of VRAM at BF16. Full 262K context adds up to 33.0 GB (100.0 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 32.7B × 16 bits ÷ 8 = 65.4 GB

KV Cache + Overhead ≈ 1.6 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 34.6 GB (at full 262K context)

Can NVIDIA GeForce RTX 5090 run Gemma 4 Novelist Eclipse 31B?

No — Gemma 4 Novelist Eclipse 31B requires at least 67.0 GB at BF16, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.

Can I run Gemma 4 Novelist Eclipse 31B on a Mac?

Yes — Mac Studio (M3 Ultra, 96GB) and 20 other Macs can run Gemma 4 Novelist Eclipse 31B. Apple Silicon uses unified memory, so the model shares RAM with the system. At BF16 you need at least 67.0 GB of usable unified memory (RAM minus macOS overhead).

Can I run Gemma 4 Novelist Eclipse 31B locally?

Yes — Gemma 4 Novelist Eclipse 31B can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Gemma 4 Novelist Eclipse 31B?

At BF16, Gemma 4 Novelist Eclipse 31B can reach ~72 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: NVIDIA B200 → 8000 ÷ 67.0 × 0.65 = ~78 tok/s
