Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the SAVRN Index, read Oct 13, 2026.

SAVRN's Notes on bert-large-NER
This is the larger sibling of the most downloaded English NER model in our catalog. Same author, same CoNLL-2003 training data, same four entity types, but built on BERT large with 334M parameters. The extra capacity buys some accuracy on ambiguous names at roughly three times the compute of the base model.
Choose it when misses cost real money, for example in compliance or due-diligence extraction, and the base model's errors show up in review. For bulk tagging where speed matters more, the base version is the sensible default. Both carry the MIT license, so commercial use is allowed with the notice kept.

Model description
bert-large-NER is a fine-tuned BERT model that is ready to use for Named Entity Recognition and achieves state-of-the-art performance for the NER task. It has been trained to recognize four types of entities: location (LOC), organizations (ORG), person (PER) and Miscellaneous (MISC).
Specifically, this model is a bert-large-cased model that was fine-tuned on the English version of the standard CoNLL-2003 Named Entity Recognition dataset.
If you'd like to use a smaller BERT model fine-tuned on the same dataset, a bert-base-NER version is also available.

Questions About bert-large-NER
How much GPU memory does bert-large-NER need?
About 0.8 GB at 16-bit and 0.2 GB at 4-bit: the weights (334M parameters) plus a working margin. A long context needs more.
What is the cheapest GPU to run bert-large-NER on?
At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.
Can I use bert-large-NER commercially?
Yes. bert-large-NER is released under MIT License. The MIT License is a short permissive license. It permits commercial use, modification and redistribution, provided the copyright notice and permission notice are included.
What is bert-large-NER's context length?
512 tokens, from the maximum position embeddings in its published configuration.

GLiNER2.5 Multi is the multilingual boundary checkpoint. It is built on mDeBERTa-v3-base and is the default choice when you need entities, classification, records, and relations in one model across languages. Load it with AutoExtractor: the checkpoint's architecture field selects BoundaryExtractor automatically. Fine-tune via Fastino. Join discussions on Reddit. This card is for fastino/gliner2.5-multi-v1. All three checkpoints share the same public API. Python 3.10 or newer is required. The [local] extra pulls in PyTorch so you can load Hub checkpoints. Always use AutoExtractor for GLiNER2.5. GLiNER2.frompretrained(...) is the legacy span loader and will not dispatch this checkpoint.…
