m-mia/pythia-6.9b-deduped

This is an unofficial safetensors mirror of EleutherAI/pythia-6.9b-deduped.

EleutherAI did not upload safetensors shards to the original repo as of 2026-05-28 — only pytorch_model-*.bin files exist there. This caused multi-process inference loads to bottleneck on disk because pickle deserialization is in-process work that doesn't share well via OS page cache. Loading 8 sweep procs of pythia-12b-deduped from .bin took ~50 min on local NVMe; safetensors zero-copy mmap drops that to ~5 min.

Origin

Weights are bit-identical to EleutherAI/pythia-6.9b-deduped — converted with:

python

model = AutoModelForCausalLM.from_pretrained("EleutherAI/pythia-6.9b-deduped", torch_dtype=torch.float16)
model.save_pretrained(out_dir, safe_serialization=True, max_shard_size="10GB")
