About
LLM-jp-3 is the series of large language models developed by the Research and Development Center for Large Language Models at the National Institute of Informatics.
This repository provides llm-jp-3-150m model. For an overview of the LLM-jp-3 models across different parameter sizes, please refer to:

The tokenizer of this model is based on huggingface/tokenizers Unigram byte-fallback model.
The vocabulary entries were converted from llm-jp-tokenizer v3.0.
Please refer to README.md of llm-jp-tokenizer for details on the vocabulary construction procedure (the pure SentencePiece training does not reproduce our vocabulary).
The models have been pre-trained using a blend of the following datasets.
| Language | Dataset | Tokens |
|---|---|---|
| Japanese | Wikipedia | 2.6B |
| Common Crawl | 762.8B | |
| WARP/PDF | 237.3B | |

Detailed evaluation results are reported in this blog.
The models released here are in the early stages of our research and development and have not been tuned to ensure outputs align with human intent and safety considerations.

Using it via the API
Once AxForge deploys llm-jp-3 for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (llm-jp-3 below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/chat/completions \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"llm-jp-3","messages":[{"role":"user","content":"Hello"}]}'
