Model overview
Five 160M GPT-NeoX training runs on the separate M/C/G source pools in Dolma3-16B. `Clean`, `M500`, `C500`, `G500`, and `MCG500` are separate run directories under `runs/`. Each contains all existing `step-*.pt` checkpoints, including the final `step-122071.pt` after 16,000,090,112 tokens. Intermediate checkpoints are approximately 1B tokens apart, with additional scheduled steps. Standalone final weights are under `models/ /model.safetensors`, with a matching config and tokenizer in each run directory. Load one with `GPTNeoXForCausalLM.from_pretrained("294-288-pretrain-interaction/160M-exp", subfolder="models/Clean")` and the tokenizer from the same subfolder. Each `.pt` is a PyTorch training checkpoint containing `model`, optimizer, scheduler, rank RNG states, step, token count, and run/manifest/config hashes. The `.pt` files are **not** direct `from_pretrained` artifacts. For trusted checkpoints, load the `model` state dict into `GPTNeoXForCausalLM(GPTNeoXConfig.from_json_file("config.json"))`. Use the included `tokenizer/`. The `training/` directory contains the training and data code; `manifest.json` fixes the source mixture, event schedule, and seeds.

Limitations & considerations
Sources are insufficient to establish specific limitations. Verify task performance, latency, data policies, licensing and version lifecycle.
Source prices & cost analysis
Prices vary by channel, region and configuration. Channel quotes are listed independently and are not treated as a single official provider price.

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
