Why Manual Prompt Iteration Doesn't Scale

The problem Opik Agent Optimizer solves: manually tweaking a prompt, running it, eyeballing the output, and repeating doesn't scale — and results can degrade when you switch models.

Key points
- •The problem: manually tweaking a prompt, running it, eyeballing the output, and repeating doesn't scale as prompt count grows
- •A subtler problem: prompts hand-tuned against one model's quirks can silently overfit and degrade when you switch models
- •Opik Agent Optimizer replaces the manual tweak-run-eyeball loop with an automated, dataset-grounded iteration process
- •The core idea: start with an initial prompt and an evaluation dataset, let an LLM iteratively improve the prompt based on evaluations
- •This doesn't remove the need to define what 'good' looks like — it removes the human from the repetitive iteration loop itself
