TimesFM 2.5 is the latest update to Google Research's pretrained time-series foundation model — a 200M parameter decoder-only model that does zero-shot forecasting across virtually any time-series domain without needing to retrain or fine-tune. Released March 31, 2026, it expands context length to 16,000 time steps (up from earlier versions) and adds an optional 30M continuous quantile head for probabilistic forecasting up to 1,000 steps ahead. Unlike traditional forecasting approaches that require training a new model per dataset, TimesFM was pre-trained on 100 billion real-world time points across diverse domains. You point it at new data — retail sales, server metrics, energy demand, financial prices — and it forecasts without any additional training. The March 31 update also restores covariate (XReg) support and updates inference APIs for better integration. With 14,000 GitHub stars and trending today, TimesFM is becoming the default baseline for time-series work in the same way BERT became the baseline for NLP tasks. Google Cloud users get it directly via BigQuery ML's AI.FORECAST function. For everyone else, it's available on HuggingFace and installable as a Python package.

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
“Zero-shot forecasting that competes with supervised models trained specifically on your dataset is remarkable. The BigQuery ML integration makes this accessible to data teams without ML infrastructure. 16k context is enough for 13+ years of daily data.”
“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.”
“Zero-shot is impressive in benchmarks but enterprise forecasting often has domain-specific seasonality and causal structure that a foundation model can't infer without fine-tuning. The 200M parameter model still requires non-trivial GPU resources for self-hosting.”
“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.”
“Time-series is the dark matter of AI applications — it's everywhere (supply chains, energy grids, healthcare) but historically required expensive specialist models. Foundation models democratizing this could unlock huge productivity in industries that have been stuck with Excel.”
“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.”
“For content creators tracking engagement trends, ad performance, or audience growth, having a zero-shot model that can forecast without a data science team is genuinely empowering. Hook it up to your analytics data and stop guessing.”
“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.”
