Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might have been a recent update to the model or training data. Has there been any significant change to Codeium's underlying AI model or training dataset in the past month?

Why it matters: Changes to the core AI model could directly impact accuracy. Expected answer: Yes, there was a model update or No, the model hasn't changed. Impact on approach: If yes, we'd focus on model-related issues; if no, we'd look more at data quality or system changes.

• Considering user segments, I'm curious about the distribution of the accuracy drop. Is the 15% decrease uniform across all programming languages and user types, or is it more pronounced in specific areas?

Why it matters: This helps identify if the issue is global or localized to certain segments. Expected answer: It's uniform or It varies by language/user type. Impact on approach: Uniform drop suggests a system-wide issue, while variations point to specific language models or user segments needing attention.

• Thinking about external factors, have there been any significant changes in the competitive landscape or industry standards for code completion in the past month?

Why it matters: External shifts could influence user expectations or behavior. Expected answer: Yes, there have been industry changes or No, the landscape remains stable. Impact on approach: If yes, we might need to reassess our benchmarks; if no, we focus more on internal factors.

• Considering system health, I'm wondering about our monitoring setup. Have there been any changes to how we measure or define code completion accuracy in the last month?

Why it matters: Ensures we're comparing apples to apples in our metrics. Expected answer: No changes to measurement or Yes, we've adjusted our metrics. Impact on approach: If changed, we need to re-evaluate our baseline; if not, we can trust the comparative data.
