    The EODHD causal AI framework analyzes how valuation, volatility, and profitability affect a stock’s downside. The data comes from ten years of S&P 500 stocks, which is more than enough to see how company characteristics shape real risk, not just statistical noise.

    OpenAI has made tech waves in the recent years with the remanent of LLMs as search engine reindexing algorithms. The biggest issue, however, is that OpenAI is extremely centralized and has a business model that is based off of incentivizing data harvesting. This led me to build AI systems based on open peering that aims to democratize LLMs and AI applications.
