24 of 32 layers cache only a 2,048-token window rather than the full context, on a period of 4. Figures assume the default configuration; --swa-full disables the saving entirely.

Why other calculators give a different number
A parameters × bits ÷ 8 estimate puts Q4_K_M at roughly 13.69 GiB. The real file is 14.74 GiB, because a quantization is a mixture and some tensors are always kept at higher precision. The larger discrepancy is the cache: a flat formula gives 2.00 GiB at 32K context where the real figure is 0.62 GiB, because most of this model's layers cache a fixed window rather than the whole context.
Architecture
Questions people ask
- How much VRAM does Trinity-Mini need?
- Q4_K_M is exactly 15,823,053,440 bytes (14.74 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.
- How large is Trinity-Mini's KV cache?
- 0.62 GiB at 32K context with an f16 cache, computed per layer. Quantizing the cache to q8_0 roughly halves it, which is often the difference between a context length fitting and not.
- Is Trinity-Mini a mixture-of-experts model?
- Yes — 128 experts, 8 routed per token. Every expert must be resident, but only the routed ones are read per token, which is why its memory requirement and its speed behave very differently.
- Which quantization of Trinity-Mini should I use?
- Q4_K_M is the usual default. Pick the largest quantization that fits your card at the context you actually need — the table above gives exact sizes for every one published.
