7.0B parameters, published in F16. View on Hugging Face
pythia-6.9b is published by EleutherAI on Hugging Face, with 62,205 downloads and 65 likes to date. It's a GPTNeoXForCausalLM model built for text-generation, published natively in F16.
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) |
|---|---|---|---|---|---|
| FP16 | 13.0 GB | 15.6 GB | V100 | 1 | $0.088/hr |
| FP8 (quantized) | 6.5 GB | 7.8 GB | RTX 5060 Ti | 1 | $0.110/hr |
| INT4 (quantized) | 3.3 GB | 3.9 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 pythia-6.9b at its published (F16) precision: 1× V100, at $0.088/hr per GPU ($0.088/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
pythia-6.9b: common questions
Does pythia-6.9b fit on a 16 GB GPU?
Yes. At FP16 it needs 15.6 GB of VRAM, so a 16 GB card holds it with 0.4 GB to spare. A 12 GB card is not enough for it at FP16.
What is the least VRAM pythia-6.9b can run in?
3.9 GB, at INT4 (quantized), which fits a 6 GB card, against 15.6 GB at FP16. That row assumes an INT4 checkpoint has actually been published for this model, so check its Hugging Face page before planning around it.
