Clarifying Questions (3 minutes)

• Based on the competitive landscape, I'm thinking accuracy might be our key differentiator. Could you share how our accuracy compares to our main competitors in noisy environments?

Why it matters: Helps determine if we need to prioritize accuracy improvements Expected answer: We're slightly behind in noisy environments Impact on approach: Would lean towards optimizing for accuracy if we're behind

• Considering our revenue model, I assume we charge per API call. Is this correct, and are there any volume-based pricing tiers?

Why it matters: Influences the impact of processing time on our business model Expected answer: Yes, with tiered pricing for high-volume users Impact on approach: Faster processing could encourage higher usage and revenue

• Looking at user behavior, I'm curious about the most common use cases for our API. Are they primarily real-time applications or batch processing?

Why it matters: Determines the relative importance of speed vs. accuracy Expected answer: Mix of both, with a growing trend towards real-time Impact on approach: Might suggest a dual-optimization strategy

• From a technical perspective, I'm wondering about our current infrastructure scalability. How easily can we add more processing power if needed?

Why it matters: Affects the feasibility of improving both accuracy and speed Expected answer: Scalable, but with associated costs Impact on approach: Could explore a hybrid solution leveraging cloud resources

• Regarding our product roadmap, are there any upcoming features or integrations that might be affected by this decision?

Why it matters: Ensures alignment with long-term product strategy Expected answer: Planning integration with a major streaming platform Impact on approach: Might prioritize accuracy for high-profile partnership
