Key Factors When Choosing a Content Generation API

Output token price: Content generation is output-heavy. A 1,500-token article costs 3-5× more in output than input tokens. Focus on output pricing.
Quality vs cost: Budget models handle product descriptions and social media well. Blog posts and whitepapers benefit from mid-tier models.
Context window: Larger context = better consistency across long content. Gemini Flash offers 1M context at budget pricing.
Latency: For high-volume pipelines, faster models mean less queuing. Budget models are typically 2-3× faster.
Rate limits: Content pipelines often hit rate limits. DeepSeek and Gemini have generous limits. Check before committing.
