CHEMLLM-2b-1_5 safetensors model info | Hugging Bay

Q: What is this model?

AI4Chem/CHEMLLM-2b-1_5 is an open-weights language model for text generation published by AI4Chem, added to Hugging Bay Jun 30, 2026. Model from Hugging Face for text generation: AI4Chem/CHEMLLM-2b-1_5 · transformers

Q: Can I use it commercially?

It is released under the apache-2.0 license. Commercial use is allowed. Permissive open license: commercial use, modification, and redistribution are permitted.

Q: How big is it?

AI4Chem/CHEMLLM-2b-1_5 has 2B parameters. Hosted here: 11 files, 3.78 GB. Full repo upstream: 3.78 GB. The recommended download, a 4-file weight set, is 3.78 GB.

Q: What can I download here?

Hosted here: 11 files, 3.78 GB. Full repo upstream: 3.78 GB. The original release is at https://huggingface.co/AI4Chem/CHEMLLM-2b-1_5.

Q: File pattern scans

Automated file-pattern scans flagged nothing; not a safety guarantee. 11 hosted files carry a published SHA-256 you can re-hash. The machine-readable verdict is at /api/artifacts/hf-model-ai4chem-chemllm-2b-1-5/safety on Hugging Bay.

Q: Will AI4Chem/CHEMLLM-2b-1_5 run on my computer?

We can’t check the fit; we don’t know your machine. We don’t have your machine’s specs, so no check ran and no verdict is shown. Answer two quick questions and we’ll estimate, from the memory you tell us, whether it fits your machine. Or skip it; you can still download; fit isn’t checked.

Quick answer: compatibility and sources

Can I run CHEMLLM-2b-1_5 on my computer?

It depends on your memory, processor, file format and runtime. A download is not confirmed by the current file evidence; inspect the file record before trying it. A file-size fit is an estimate, not a successful run or speed promise. Read the license before use.

CHEMLLM-2b-1_5 is an open-weights language model for text generation. Model weights are learned parameters; a runtime loads them. A hosted file is an individual file Hugging Bay can serve. SHA-256 identifies exact file bytes. The availability date above applies to this file record, not the upstream metadata update date.

As of the recorded file availability check on 2026-11-01.

A checksum fingerprints only the named file bytes; it does not prove safety, quality, a complete multi-file selection or a successful run.

Model metadata: As of 2026-09-04 at the model source. Popularity counters are source-reported, not measured by Hugging Bay. Availability checked 2026-11-01.

Key facts

Catalog record: Summarizes upstream metadata; it is not itself a download or run receipt.
File evidence: Lists exact filenames, availability and any recorded SHA-256 for individual files.
Run evidence: Reports measured results only when a receipt exists for named file bytes and a setup; otherwise unmeasured.
Checksum scope: SHA-256 fingerprints one file’s bytes; it does not prove safety, quality or a multi-file bundle.

Evidence you can inspect (plain text)

This page’s quick answer names the file record for hf-model-ai4chem-chemllm-2b-1-5.
Open /artifact/hf-model-ai4chem-chemllm-2b-1-5/files for exact filenames, availability and any recorded SHA-256 for this model.
Open /evidence/artifacts/hf-model-ai4chem-chemllm-2b-1-5 for run-readiness evidence tied to that record; absent receipts stay unmeasured.
Open /api/artifacts/hf-model-ai4chem-chemllm-2b-1-5/card.md for machine-readable source facts (not a runtime test).
A matching checksum on this page fingerprints only the named bytes shown in file evidence.

Unmeasured states are stated explicitly; this page does not invent run scores or compatibility guarantees.

Which date applies to which fact

File availability check: 2026-11-01
