CodeGen 350M Mono

CodeUnavailable

by Salesforcecodegen-350m-mono

350M autoregressive code generation model from Salesforce, the smallest of the original CodeGen family. The mono variant was further trained on Python so it is well suited for short Python completions and program synthesis from a natural-language or code prompt.

About CodeGen 350M Mono

TL;DRAs of 23 September 2026

CodeGen 350M Mono is a model by Salesforce in the Code category. CodeGen 350M Mono is currently not available on Railwail. The context window holds 2,048 tokens.

CodeGen-350M-mono is the lightest checkpoint of Salesforce's CodeGen family of program-synthesis models. It started from the multilingual CodeGen base and was then fine-tuned on a large Python corpus, which makes the mono variant focused on Python code generation. With only 350M parameters it runs cheaply and is a common baseline for code-completion and text-to-code experiments, though its output quality trails much larger modern code models.

Pricing

Currently unavailable. There is no price for this model at the moment, so it cannot be run.
