Kronos is the first open-source foundation model purpose-built for financial candlestick (K-line / OHLCV) data, accepted at AAAI 2026. Instead of treating price series like text or images, Kronos uses a custom two-stage architecture: a specialized tokenizer that converts continuous OHLCV data into discrete tokens, followed by an autoregressive Transformer trained on data from 45+ global exchanges. Four model sizes range from 4.1M to 499M parameters, all released under MIT license. The model learns the statistical structure of market microstructure directly from raw candlestick sequences, enabling zero-shot and few-shot forecasting across asset classes — equities, crypto, and commodities. It ships with a live BTC/USDT prediction demo, Qlib integration for A-Share markets, and a backtesting framework so researchers can evaluate strategies end-to-end. With 13.6k GitHub stars in a niche domain, the community reception has been unusually strong. Kronos matters because most "AI for trading" projects glue LLMs to news sentiment or financial reports — pattern-matching on text rather than market structure. Kronos is the rare project that treats price action itself as the primary modality, giving quants and ML researchers a base model they can fine-tune on proprietary data rather than starting from scratch on every new dataset.

R0Y (pronounced "Roy") is a no-code financial studio where you describe the analysis you want in plain English and it builds interactive investing dashboards instantly. Ask for "a momentum backtest on NVDA vs. SPY over 3 years" or "macro correlation between rate hikes and emerging market ETF drawdowns" and R0Y assembles a live, interactive system with real data from hundreds of millions of data points — no SQL, no Python, no Bloomberg terminal required. The platform connects to market data, economic indicators, and financial databases to generate projections, strategy models, and backtesting frameworks on demand. Dashboards are shareable with team-specific customization, making it useful for investment clubs, family offices, and individual traders who want institutional-grade analysis without the institutional-grade tooling cost. It's free to start with a freemium model. Launched on Product Hunt this week and hit the top three on launch day. The interface is built on React with KlineCharts for financial visualization, Supabase for backend, and Google's generative AI — a surprisingly capable technical stack for what appears to be an early-stage indie project.
Reviewer scorecard
“Finally a foundation model that speaks OHLCV natively instead of forcing price data through text embeddings. The Qlib integration and Hugging Face weights mean you can fine-tune on your own tick data in an afternoon. MIT license and four model sizes give you real options.”
“Natural language to working financial dashboards with real data is a workflow most analysts spend days setting up. If the data sources are solid and the backtest logic is sound, this is legitimately useful. The free tier makes it easy to evaluate before committing.”
“The disclaimer that this is 'not a production trading system' is doing a lot of work. Financial time series are notoriously non-stationary, and a model pre-trained on historical patterns from 45 exchanges may carry regime-specific biases that hurt live trading. Benchmark numbers on held-out historical data say nothing about alpha in live markets.”
“AI-generated backtests with 'hundreds of millions of data points' is exactly the kind of marketing language that hides survivorship bias and look-ahead bias. Any serious investor knows that a backtest is easy to generate and almost meaningless without rigorous methodology — this could give beginners false confidence in bad strategies.”
“This is the ImageNet moment for market microstructure modeling. Once researchers have a shared pre-trained foundation to build on, progress will compound rapidly — we'll see specialized variants for volatility forecasting, options pricing, and market-making within months. AAAI acceptance gives it the academic credibility to attract serious contributors.”
“Democratizing quantitative finance is a decade-long trend that's now accelerating rapidly. R0Y is part of a wave that will eventually let retail investors run the kind of macro analysis that hedge funds pay analysts six figures to produce. The direction is right even if early versions are imperfect.”
“If you're not deep in quantitative finance, the barrier to actually using Kronos is steep — you need to understand OHLCV data, Qlib configuration, and backtesting pipelines before you see any value. The live BTC demo is cool to watch but hard to translate into a personal use case.”
“The ability to generate a shareable interactive dashboard from a natural language prompt is genuinely exciting for anyone who writes financial content or manages a Substack portfolio tracker. No more fighting with Sheets or Notion embeds.”
