7.6B parameters, published in BF16. View on Hugging Face
Set up openthaigpt1.5-7b-instructopenthaigpt1.5-7b-instruct is published by openthaigpt on Hugging Face, with 82,927 downloads and 16 likes to date. It's a Qwen2ForCausalLM model built for text-generation, published natively in BF16.
VRAM required & cheapest live GPU fit
Required VRAM = weight size at each precision, plus a fixed overhead for KV-cache, activations, and fragmentation. Full formula and assumptions: methodology.
| Precision | Weight size | Required VRAM | Cheapest live fit | GPUs needed | Est. $/hr (full fit) |
|---|---|---|---|---|---|
| BF16 | 14.2 GB | 17.0 GB | RTX A5000 | 1 | $0.176/hr |
| FP8 (quantized) | 7.1 GB | 8.5 GB | RTX 5060 Ti | 1 | $0.110/hr |
| INT4 (quantized) | 3.5 GB | 4.3 GB | RTX 5060 Ti | 1 | $0.110/hr |
A GPU is only matched to a row if its hardware supports that precision, and the primary recommendation is always a single-GPU fit when one exists.
INT4 requires a quantized checkpoint actually published for this model, check its Hugging Face page before relying on this row.
Cheapest way to run openthaigpt1.5-7b-instruct at its published (BF16) precision: 1× RTX A5000, at $0.176/hr per GPU ($0.176/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
openthaigpt1.5-7b-instruct: common questions
Does openthaigpt1.5-7b-instruct fit on a 24 GB GPU?
Yes. At BF16 it needs 17.0 GB of VRAM, so a 24 GB card holds it with 7.0 GB to spare. A 16 GB card is not enough for it at BF16.
What is the least VRAM openthaigpt1.5-7b-instruct can run in?
4.3 GB, at INT4 (quantized), which fits a 6 GB card, against 17.0 GB at BF16. That row assumes an INT4 checkpoint has actually been published for this model, so check its Hugging Face page before planning around it.
Does quantizing openthaigpt1.5-7b-instruct lower the GPU bill?
Yes. At BF16 the cheapest live fit is one RTX A5000 at $0.176/hr. At FP8 (quantized) it drops to one RTX 5060 Ti at $0.110/hr, provided a quantized checkpoint exists for it.
