Everyone knows that writing letters of recommendation is hard work and not everyone's cup of tea, but on the other hand it is essential to be able to apply for some jobs. Why not use artificial intelligence to do so? I have created an application using the GPT2 model model trained to generate letters of recommendation. The application is built using flask and docker, the service is deployed on Cloud Run (GCP).

GPT-2 is a large transformer-based language model with 1.5 billion parameters, trained on a dataset of 8 million web pages. GPT-2 is trained with a simple objective: predict the next word, given all of the previous words within some text. The diversity of the dataset causes this simple goal to contain naturally occurring demonstrations of many tasks across diverse domains. GPT-2 is a direct scale-up of GPT, with more than 10X the parameters and trained on more than 10X the amount of data.
-
GPT-2 is a model with absolute position embeddings so it’s usually advised to pad the inputs on the right rather than the left.
-
GPT-2 was trained with a causal language modeling (CLM) objective and is therefore powerful at predicting the next token in a sequence. Leveraging this feature allows GPT-2 to generate syntactically coherent text as it can be observed in the run_generation.py example script.
-
The PyTorch models can take the past as input, which is the previously computed key/value attention pairs. Using this past value prevents the model from re-computing pre-computed values in the context of text generation. See reusing the past in generative models for more information on the usage of this argument.

1- Clone the repository in your local machine:
https://github.com/alejandrods/cover-letter-generator-gpt2
2- Download model using get_model.py
3- Set environment variables - Check .env file for env. variables required
HOST (i.e: http://localhost)
PORT (i.e: 8080)
ROUTE_GENERATE (Route for the application - i.e: generate)
N_TOKENS (Number of words to be generated - i.e: 20)
4- Build Image using Docker
docker build -t cover-letter-generator-gpt2 .
If you are using Apple M1 Chip:
docker buildx build --platform linux/amd64 -t cover-letter-generator-gpt2 .
5- Run Docker Image
docker run --name cover-letter-generator-gpt2 --env-file=.env -p 8080:8080 cover-letter-generator-gpt2
6- Visit http://localhost:8080
If you are not enable to run
Docker, you can run the application using:python src/app.py
