Claude + GPT-4 working together.
History Traveled uses Anthropic's Claude (Haiku) for structured marker analysis: categorization, era detection, content moderation, and geolocation validation via Firebase Cloud Functions.
OpenAI GPT-4 generates rich historical narratives and contextual facts for each marker, giving users depth beyond the metadata.
Prompt caching drives ~90% cost reduction on repeated analysis queries. AI at scale without the runaway bill.
Not every task needs a frontier model. Haiku handles high-volume classification at sub-second speed for a fraction of the cost. GPT-4 is reserved for the one job that actually demands generative depth. That distinction matters at scale.
