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.

Zen Reports connects to your Google Analytics in about 30 seconds and shows you exactly how many visitors ChatGPT, Gemini, Claude, Perplexity, and Copilot are sending to your website — broken down by source, landing page, and trend over time. It's read-only, requires no code changes, and is completely free. As AI chatbots increasingly act as the new search engines — ChatGPT alone has grown 206% year-over-year in outbound referral traffic and now holds 64.5% of the Gen AI referral market — understanding which pages and content resonate with AI-driven recommendations is becoming a crucial SEO and marketing signal. Zen Reports surfaces this data in a simple, focused dashboard purpose-built for the GEO (Generative Engine Optimization) era. The tool launched on Product Hunt this week and immediately resonated with marketers and content creators trying to understand why their AI referral traffic is up or down. It fills a gap that traditional analytics tools have been slow to address — most don't break down referral sources by AI chatbot, and Zen Reports does exactly one thing well.
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.”
“Instant Google Analytics integration, no code, read-only access, free — this is how you launch a focused dev tool. The data it surfaces (which pages ChatGPT links to) is genuinely useful for content strategy and API documentation optimization.”
“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.”
“This is a single-feature wrapper around data Google Analytics already exposes — you can build this custom report in GA4 in five minutes. The 'AI referral traffic' category is still small for most sites, and a free tool with no monetization model raises questions about longevity.”
“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.”
“GEO (Generative Engine Optimization) is going to be as important as SEO within 18 months. Zen Reports is the right tool at the right moment — the teams that understand their AI referral patterns now will have a compounding advantage as chatbot-driven discovery accelerates.”
“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.”
“Finally a tool that tells me whether my content is actually getting picked up by AI assistants. Knowing which posts ChatGPT cites helps me write more of what works — this is the missing feedback loop for every content creator trying to stay visible in the AI era.”
