## Model Description
|
52 |
`replit-code-v1-3b` is a 2.7B Causal Language Model focused on **Code Completion**. The model has been trained on a subset of the [Stack Dedup v1.2 dataset](https://arxiv.org/abs/2211.15533).
|
53 |
|
54 |
The training mixture includes **20 different languages**, listed here in descending order of number of tokens:
|
|
|
57 |
|
58 |
In total, the training dataset contains 175B tokens, which were repeated over 3 epochs -- in total, `replit-code-v1-3b` has been trained on **525B** tokens (~195 tokens per parameter).
|
59 |
|
60 |
+
## Intended Use
|
61 |
+
Replit intends this model be used by anyone as a foundational model for application-specific fine-tuning without strict limitations on commercial use.
|
62 |
|
63 |
+
## Limitations
|
64 |
+
The pre-training dataset may have contained offensive or inappropriate content even after applying data cleansing filters, and such content may be reflected in model generated text. We recommend that users exercise reasonable caution when using in production systems. Do not use for any applications that may cause harm or distress to individuals or groups.

The base model checkpoint is licensed under the Creative Commons license (CC BY-SA-4.0). Under the license, you must give credit to Replit, provide a link to the license, and indicate if changes were made. You may do so in any reasonable manner, but not in any way that suggests that Replit endorses you or your use.

## How to Use
|
73 |
```python
|
74 |
from transformers import AutoModelForCausalLM
|
75 |
|
|
|
96 |
Note that `trust_remote_code=True` is passed to the `from_pretrained` method because ReplitLM is not a class in the

### Tokenizer
|
100 |
|
101 |
We have trained a custom SentencePiece Unigram tokenizer optimized with a vocabulary specifically for code of 32768 tokens.
|
102 |
|
|
|
124 |
- `clean_up_tokenization_spaces=False` is meant to avoid removing spaces in the output, because that would affect the syntactical correctness of the generated code.
|
125 |
|
126 |
|
127 |
+
### Generation
|
128 |
|
129 |
You can generate code using the `transformers` library as follows:
|
130 |
|
|
|
142 |
|
143 |
Experiment with different decoding methods and parameters to get the best results for your use case.
|
144 |
|
145 |
+
### Post Processing
|
146 |
|
147 |
Note that as with all code generation models, post-processing of the generated code is important. In particular, the following post-processing steps are recommended:
|
148 |
- stop generation when the EOS token is encountered
|
|
|
150 |
- set `max_tokens` to a reasonable value based on your completion use case
|
151 |
- truncate generation to stop words such as `return`, `def`, "```", "`\n\n\n`" to avoid generating incomplete code when `max_tokens`Β is larger than the length of the expected generated code.
