GDELT Project (global event database)

How we use these sources

Each scrape run pulls fresh content from the sources above, deduplicates against what we've already seen, and runs the resulting items through a multi-stage filter:

  1. Keyword pre-filter drops items that don't mention Cuba-relevant entities, sectors, programs, or named officials. About 70% of incoming items get dropped at this step.
  2. Tone score from GDELT (where applicable) is used to prioritise items that read as either materially negative or materially positive — neutral wire copy is deprioritized.
  3. LLM analysis assigns a 1-10 investor-relevance score, an English headline, sector tags, sentiment, and an investor takeaway. Items scoring below 5 are not published. The analyzer runs only on items that survive the first two filters, which keeps daily LLM cost under $5.
  4. Long-form analysis (the /briefing posts) is generated for items scoring 5+ using GPT-4o.
  5. Pillar and sector pages (/invest-in-cuba and /sectors/*) are regenerated weekly using the GPT-5 family for higher-quality evergreen prose.

Editorial standards

This site is independent commentary by an analyst team, not investment advice. Where an LLM has authored the body of a briefing or landing page, that's noted. Every page links back to the primary source so you can verify the underlying facts before acting. We publish corrections in the next scheduled briefing window when errors are identified.
