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.

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.”
“The most cost-effective vector database for large-scale search. Object storage backend keeps costs predictable.”
“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.”
“Radical cost reduction for vector search. If your vectors are mostly at rest, turbopuffer's economics are compelling.”
“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.”
“Serverless vector search with aggressive cost optimization addresses the biggest barrier to vector adoption at scale.”
“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.”
