OpenAI Codex

OpenAI Codex is an

fine-tuned
for use in programming applications.

OpenAI released an

closed beta.[1] In March 2023, OpenAI shut down access to Codex.[2] Due to public appeals from researchers, OpenAI reversed course.[3] The Codex model can still be used by researchers of the OpenAI Research Access Program.[4]

Capabilities

Based on GPT-3, a neural network trained on text, Codex was additionally trained on 159 gigabytes of Python code from 54 million GitHub repositories.[5][6] A typical use case of Codex is for a user to type a comment, such as "//compute the moving average of an array for a given window size", then use the AI to suggest a block of code that satisfies that comment prompt.[7] OpenAI stated that Codex can complete approximately 37% of requests and is meant to make human programming faster rather than to replace it. According to OpenAI's blog, Codex excels most at "mapping... simple problems to existing code", which they describe as "probably the least fun part of programming".[8][9] Jeremy Howard, co-founder of Fast.ai, stated that "Codex is a way of getting code written without having to write as much code", and that "it is not always correct, but it is just close enough".[10] According to a paper written by OpenAI researchers, when Codex attempted each test case 100 times, it generated working solutions for 70.2% of prompts.[11]

OpenAI claims that Codex can create code in over a dozen programming languages, including

coreference resolution capabilities. The demonstrators were able to create a browser game in JavaScript and generate data science charts using matplotlib.[9]

A very powerful language model called OpenAI Codex was created expressly to generate code in response to natural language commands. It is capable of understanding and producing code in a multitude of areas because it is compatible with a large number of programming languages and libraries. Codex is a useful tool for developers who want to optimize their coding processes because it can debug, parse natural language inquiries, and provide code completions.[12]

OpenAI showed that Codex can interface with services and apps such as Mailchimp, Microsoft Word, Spotify, and Google Calendar.[9][13]

Issues

OpenAI demonstrations showcased flaws such as inefficient code and one-off quirks in code samples.[9] In an interview with The Verge, OpenAI chief technology officer Greg Brockman said that "sometimes [Codex] doesn't quite know exactly what you're asking" and that it can require some trial and error.[13] OpenAI researchers found that Codex struggles with multi-step prompts, often failing or yielding counter-intuitive behavior. Additionally, they brought up several safety issues, such as over-reliance by novice programmers, biases based on the training data, and security impacts due to vulnerable code.[11]

VentureBeat stated that because Codex is trained on public data, it could be vulnerable to "data poisoning" via intentional uploads of malicious code.[9] According to a study by researchers from New York University, approximately 40% of code generated by GitHub Copilot (which uses Codex) in scenarios relevant to high-risk CWEs included glitches or other exploitable design flaws.[14]

The

GPL that requires derivative works to be licensed under equivalent terms.[15] Issues they raised include whether training on public repositories falls into fair use or not, how developers could discover infringing generated code, whether trained machine learning models could be considered modifiable source code or a compilation of the training data, and if machine learning models could themselves be copyrighted and by whom.[15][16] An internal GitHub study found that approximately 0.1% of generated code contained direct copies from the training data. In one example the model outputted the training data code implementing the fast inverse square root algorithm, including comments and an incorrect copyright notice.[7]

In response, OpenAI stated that "legal uncertainty on the copyright implications of training AI systems imposes substantial costs on AI developers and so should be authoritatively resolved."[7]

The copyright issues with Codex have been compared to the Authors Guild, Inc. v. Google, Inc. court case, in which judges ruled that Google Books's use of text snippets from millions of scanned books constituted fair use.[7][17] However, use of text snippets from books provides for a reliable reference of the copyright owner, as opposed to compiled works used for the training algorithm data where the final output is made without any such reference.
