> While OpenAI originally pioneered Codex (which went on to power GitHub Copilot), Google’s direct answer for dedicated, native code completion and natural-language-to-code generation is CodeGemma.
Nothing about this is a hallucination. The Codex that it talks about is real, existed, and did go on to power the original Copilot. You neither specified that you meant a different Codex, nor did it make anything up. The CodeGemma isn't made up either, as its referenced working link shows.
