Factual AI capabilities

OpenAI launched Codex, an API that uses AI to write code from natural language, on 2021-08-10.

Resolved true The record shows it happened or was so.

Factual: Statements about the present or the past, checked against the record: did they hold up?

Said for an organisation they lead or work for; it counts on both records.

What would count as true or false

True: OpenAI publicly launched or released Codex on 2021-08-10 (including a private beta API release that day), described as an AI system or model that translates natural language into code and is offered through its API. Mostly true: the launch happened as described, but with a one-day difference in date or a minor descriptive slip (e.g., it was the model rather than a separate 'API'). Mostly false: Codex was released through the API on a clearly different date (e.g., the July 2021 paper only, or a later general availability date with nothing on 08-10), or it was not offered through an API at that time. False: no such launch occurred around that date.

Set before the research began.

  1. E1 OpenAI Codex OpenAI · 10 August 2021 Own record

    “We’ve created an improved version of OpenAI Codex, our AI system that translates natural language to code, and we are releasing it through our API in private beta starting today.”
  2. E2 OpenAI upgrades its natural language AI coder Codex and kicks off private beta | TechCrunch TechCrunch · 10 August 2021

    “A few lucky coders (and, one assumes, non-coders) will be able to kick the tires on this new Codex API in a free private beta.”
  3. E3 OpenAI upgrades its natural language AI coder Codex and kicks off private beta | TechCrunch TechCrunch · 10 August 2021

    “OpenAI has already made some big changes to Codex, the AI-powered coding assistant the company announced last month.”

Reasoning

OpenAI's 2021-08-10 announcement (E1) says the company was releasing an improved version of Codex, "our AI system that translates natural language to code," through its API in private beta "starting today." TechCrunch, an independent source, reported on the same date (E2, E3) that a new Codex API had opened in a free private beta. Codex had been announced the previous month, but the criteria count a private beta API release on 2021-08-10 as a launch, so the claim resolves true.
