Run time and cost

This model costs approximately $0.19 to run on Replicate, or 5 runs per $1, but this varies depending on your inputs. It is also open source and you can run it on your own computer with Docker.

This model runs on Nvidia A100 (80GB) GPU hardware. Predictions typically complete within 136 seconds. The predict time for this model varies significantly based on the inputs.

Released models

The models are named in the following format:

codegen-{model-size}-{data}

model-size has 4 options: 350M, 2B, 6B, 16B, which represent the number of parameters in each model.

data has 3 options: nl, multi, mono.

  • nl models are randomly initialized and trained on The Pile, a 825.18 GB English text corpous.
  • multi models are initialized from nl models and then trained on a corpus with code data consisting of multiple programming languages.
  • mono models are initialized from multi models and then trained on a corpus with Python code data.
