- How much VRAM does Command A Plus 05 2026 BF16 need?
Command A Plus 05 2026 BF16 requires 131.6 GB of VRAM at Q4_K_M, or 437.9 GB at BF16. Full 200K context adds up to 6.5 GB (138.1 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 218.8B × 4.8 bits ÷ 8 = 131.3 GB
KV Cache + Overhead ≈ 0.3 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 6.8 GB (at full 200K context)
VRAM usage by quantization
Q4_K_M131.6 GBQ4_K_M + full context138.1 GB- Can NVIDIA GeForce RTX 5090 run Command A Plus 05 2026 BF16?
No — Command A Plus 05 2026 BF16 requires at least 93.3 GB at Q2_K, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
- What's the best quantization for Command A Plus 05 2026 BF16?
