 # Toto-2.0-4m
 
-Toto (**T**ime Series **O**ptimized **T**ransformer for [**O**bservability](https://www.datadoghq.com/knowledge-center/observability/)) is a family of time series foundation models for multivariate forecasting developed by [Datadog](https://www.datadoghq.com/). **Toto 2.0** is the current generation, featuring u-μP-scaled transformers ranging from 4M to 2.5B parameters.
+Toto (Time Series Optimized Transformer for [Observability](https://www.datadoghq.com/knowledge-center/observability/)) is a family of time series foundation models for multivariate forecasting developed by [Datadog](https://www.datadoghq.com/). Toto 2.0 is the current generation, featuring u-μP-scaled transformers ranging from 4M to 2.5B parameters, all trained from a single recipe. Forecast quality improves reliably with parameter count across the family, with no sign of saturation at 2.5B.
+
+The family sets a new state of the art on three forecasting benchmarks: [BOOM](https://huggingface.co/spaces/Datadog/BOOM), our observability benchmark; [GIFT-Eval](https://huggingface.co/spaces/Salesforce/GIFT-Eval), the standard general-purpose benchmark; and the recent contamination-resistant [TIME](https://arxiv.org/abs/2602.12147) benchmark.

 ## ✨ Key Features
 
-- **Zero-Shot Forecasting**: Forecast without fine-tuning on your specific time series.
-- **Multi-Variate Support**: Efficiently process multiple variables using alternating time/variate attention.
-- **Probabilistic Predictions**: Generate point forecasts and uncertainty estimates via a quantile output head.
-- **Decoder-Only Architecture**: Support for variable prediction horizons and context lengths.
-- **u-μP Scaling**: Stable training transfer across all model sizes.

+## 🏗️ Architecture
+
+![Overview of the Toto 2.0 architecture.](assets/architecture.png)
+
+A decoder-only patched transformer whose attention layers alternate between time-axis (causal) and variate-axis (full) views of the input. Toto 2.0 adds **contiguous patch masking (CPM)** for single-pass parallel decoding, a **quantile output head** trained with pinball loss, a robust arcsinh input scaler, residual MLP patch projections, and is trained with NorMuon. See the [technical report](#-additional-resources) for details.
+

+
+## 📊 Performance
+
+![Pareto frontier on BOOM and GIFT-Eval](assets/pareto.png)
+
+Every Toto 2.0 size sits on or near the Pareto frontier on both BOOM and GIFT-Eval. The three largest sizes rank first, second, and third among foundation models on GIFT-Eval CRPS rank. On TIME, Toto 2.0 sizes take the top three spots on every metric, ahead of every other external foundation model evaluated.

+| [Toto-2.0-4m](https://huggingface.co/Datadog/Toto-2.0-4m)     | 4m     | ~3.8 ms  | ~10.0 ms | Edge / CPU deployment; tightest latency or memory budgets. |

+| [Toto-2.0-313m](https://huggingface.co/Datadog/Toto-2.0-313m) | 313m   | ~15.4 ms | ~32.4 ms | Strong general-purpose checkpoint; top-3 foundation model on GIFT-Eval. |
+| [Toto-2.0-1B](https://huggingface.co/Datadog/Toto-2.0-1B)     | 1B     | ~20.9 ms | ~46.3 ms | Best quality / cost tradeoff for production workloads. |
+| [Toto-2.0-2.5B](https://huggingface.co/Datadog/Toto-2.0-2.5B) | 2.5B   | ~36.2 ms | ~78.0 ms | Highest accuracy; #1 foundation model on every benchmark. |
+
+> Single-pass decoding fills the entire horizon in one forward pass and is recommended up to ~768 steps. Block decoding generates the horizon in 768-step segments conditioned on the previous segment's median (with KV caching); it is slower but more stable at long horizons. Both modes use the same checkpoint.
