+# kl3m-004-128k-uncased tokenizer
+
+**NOTE**: This is the same vocabulary as kl3m-004-128k-uncased, but packaged within a `RobertaProcessing` `post_processor` class 
+to provide special token handling without loading a custom tokenizer class.
+
+The `kl3m-004-128k-uncased` **case-insensitive** tokenizer is a domain-specific tokenizer trained on a stratified sample of nearly 4M 
+documents across general, legal, and financial domains from the `kl3m-data` project, including American English,
+British English, Spanish, German, French, Italian, and other common EU languages.  
+
+This tokenizer is being used for the next generation of KL3M embedding and generative models.
+
+Please see `kl3m-001-32k` and `kl3m-003-64k` for the first iteration of our research on domain-specific tokenization.
+
+Note that we are providing both uncased and cased versions of the 128K tokenizer, unlike prior tokenizers, as this was
+required to achieve SotA in-domain performance for embedding models on legal and financial text.

+
+### Model Description
+
+The `kl3m-004-128k-uncased` tokenizer is a domain-specific tokenizer trained on ~1.5T tokens of financial and legal text from primarily-English sources.
+
+This tokenizer is notable for a number of reasons:
+
+#### Domain Specific
+
+As part of our research on more efficient SLM training for the legal and financial domain, we
+trained a domain-specific tokenizer on a large corpus of financial and legal text. This tokenizer
+has not, for example, seen any common general pretrain sources like Wikipedia or Common Crawl.
+
+#### Large Added Token Set
+
+As part of our research on efficient and reliable extraction and generation, we inserted
+a large numer of deterministic "whole" tokens into the tokenizer, such as HTML tags
+like `<span`, common Markdown elements like `#` and `##`, and legal enumerations like `(a)`.
+
+**Note that the kl3m-004-128k-uncased tokenizer has added a number of additional citation formats that were not 
+included in the kl3m-001-32k tokenizer.**  These were primarily sourced from empirical data and
+the [Free Law Project's reporters-db](https://raw.githubusercontent.com/freelawproject/reporters-db/main/reporters_db/data/),
+which were added to the tokenizer to improve model behavior related to legal citations.
+
+See the `get_custom_tokens` method in `kl3m_embeddings/training/kl3m_004/train_tokenizer.py` for
+more details:
+
+```python
+def get_custom_tokens(
+    include_whitespace: bool = True,
+    include_markdown: bool = True,
+    include_html: bool = True,
+    include_json: bool = True,
+    include_xml: bool = True,
+    include_years: bool = True,
+    include_citations: bool = True,
+    lowercase: bool = False,
+) -> list[str]:
+```
+
+#### Space Preservation
+
+Unlike `kl3m-001-32k`, we *do not* retain the space character as a token.  This was done after adding additional legal
+citation tokens to the vocabulary, which reduced the number of issues related to space tokenization in legal text.  This
+means that the `kl3m-004-128k-uncased` tokenizer uses substantially fewer tokens than `kl3m-001-32k` for most text.
+
+#### Special Tokens for both Embedding and Generative Models
+
+For both training and inference efficiency, we intended this tokenizer vocabulary to be
+usable for both embedding and generative models. As such, we included special tokens
+suitable for both causal and masked language modeling tasks.
+
+* `<|start|>`: `0`
+* `<|end|>`: `1`
+* `<|pad|>`: `2`
+* `<|unk|>`: `3`
+* `<|sep|>`: `4`
+* `<|cls|>`: `5`
+* `<|mask|>`: `6`
+
+We also added a number of chat and instruction tokens that were not included in `kl3m-001-32k`, including:
+
+* `<|system|>`: `7`
+* `</|system|>`: `8`
+* `<|user|>`: `9`
+* `</|user|>`: `10`
+* `<|instruction|>`: `11`
+* `</|instruction|>`: `12`
+
+These tokens are identical to those used in the `kl3m-003-64k` tokenizer. 
+
+### Replication
+
+The entire data collection and preprocesing pipeline is being made available, along with
+training data, as part of the [ALEA Institute](https://aleainstitute.ai) [KL3M project](https://aleainstitute.ai/work/kl3m/).
+
+The source code to used to train the tokenizer is available on GitHub at:
+[https://github.com/alea-institute/kl3m-embedding-research](https://github.com/alea-institute/kl3m-embedding-research)
+
+The data pipeline will be available on GitHub and S3 in the near future.
+
+## Uses
+
+This tokenizer is intended to be used for English, Spanish, German, or French language text in professional contexts
+such as legal and financial documents.
+
+### Recommendations
+
+In general, the `kl3m-004-128k-uncased` tokenizer is recommended over the original `kl3m-001-32k` tokenizer.
