About
DeciCoder 1B is a 1 billion-parameter, open-source large language model focused on code generation 12. It excels at efficient and accurate code completion for Python, Java, and JavaScript using a unique Grouped Query Attention architecture with a 2048-token context window 13. Trained on a substantial dataset with a Fill-in-the-Middle objective, it offers impressive throughput, especially when used with Deci's Infery LLM inference engine 79. Although capable of single or multi-line code completion, it may produce suboptimal results as it's not an instruction-following model. Performance is benchmarked on HumanEval, showing variable accuracy across languages, and it is available under the Apache 2.0 license 25.
DeciCoder 1B is an open-source model in the DeciCoder family. The structured metadata tracks a 4k-token context window. This page tracks provider routes through Microsoft Foundry, with the cheapest tracked route listed at $0.07 input and $0.07 output per 1M tokens.
