Our Take

Both are strong general-purpose models, but they respond to prompts differently. GPT-4o tends to over-generate without grounding constraints, making Refrase's grounding rules essential. Gemini is our baseline, so standard prompt patterns already work well. Choose Gemini for long-context or multimodal; GPT-4o for API-heavy integrations.
