Large Language Models

CodeHelp can use several different large language models to generate responses to queries. By default, the following models are available in CodeHelp:

Model	Avg cost per 100 queries	Average response time	Notes
OpenAI GPT-4.1 nano	US$0.05	2 seconds	The lowest-cost and fastest of these options. It can provide accurate, helpful responses in a wide variety of cases, but it will be noticeably less accurate in less common programming languages and may exhibit less fluency writing in languages other than English.
OpenAI GPT-4.1 mini	US$0.20	6 seconds	(Recommended) The best model for most cases. It is generally as capable as GPT-4.1 but at a lower cost.
OpenAI GPT-4.1	US$1	8 seconds	The most capable model of these options. It is recommended for classes using uncommon programming languages, students asking questions in less widely-spoken languages, and/or queries with subtle or complex issues. Most CS classes and students are unlikely to see a major difference in responses between this and GPT-4.1 mini.
