Strategy: Marketing Content Pipeline
Marketing content varies wildly in quality requirements. A social media hashtag needs different AI power than a brand manifesto. Route by impact, not volume.

Marketing-Specific Considerations
- Output quality matters: Marketing copy is customer-facing. A bad product description loses sales. A bad ad wastes budget. Don't always pick the cheapest — test output quality on real campaigns first.
- A/B testing needs volume: AI excels at generating 20 ad variants for A/B testing. The marginal cost of one more variant is near zero. Use this to run more experiments.
- Brand voice needs fine-tuning: Generic AI output sounds generic. For consistent brand voice, provide style guides in the prompt (input tokens) or fine-tune a small model. Fine-tuning costs more upfront but produces better output per-token.
- SEO content is input-heavy: Blog posts and SEO pages need keyword research, competitor analysis, and outline as input. The input-to-output ratio is higher than social media content.
- Multi-channel from one prompt: One product brief can generate email, ad, social, and blog variants. Structure your prompts to produce multi-format output from a single API call to reduce per-channel costs.
