Frequently Asked Questions
- How much VRAM does Time R1 S1P2 need?
Time R1 S1P2 requires 7.2 GB of VRAM at BF16. Full 33K context adds up to 1.1 GB (8.3 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 3.4B × 16 bits ÷ 8 = 6.8 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 1.5 GB (at full 33K context)
VRAM usage by quantization
BF167.2 GBBF16 + full context8.3 GB- Can I run Time R1 S1P2 on a Mac?
Time R1 S1P2 requires at least 7.2 GB at BF16, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run Time R1 S1P2 locally?
Yes — Time R1 S1P2 can run locally on consumer hardware. At BF16 quantization it needs 7.2 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Time R1 S1P2?
At BF16, Time R1 S1P2 can reach ~407 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~91 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: AMD Instinct MI300X → 5300 ÷ 7.2 × 0.55 = ~407 tok/s
