# Introducing ci-proto, our frontier model that says goodbye to context windows and hello to accuracy

**State-of-the-art forecasting at your fingertips.**

- **2M+ context window.** Process 64× the history of any other time-series foundation
  model.
- **Frontier accuracy.** Leading forecasting performance on fev-bench.
- **CPU and GPU support.** Run locally through the same Python API.
- **Multivariate forecasting.** Turn relationships between signals into more accurate
  forecasts.
- **Uncertainty included.** Get nine quantiles between 0.1 and 0.9 to plan for a range of
  outcomes.

## Make your first forecast

**Your first forecast in a few lines.** Install with Python 3.10–3.14:

```sh
pip install continuousintelligence
```

Forecast the next day of bicycle rentals from five observed days of hourly demand
in Washington, D.C. The example history is included with the package:

```python
import continuousintelligence as ci

# Load the model (uses CUDA when available).
model = ci.load_model("ContinuousIntelligence/ci-proto")

# Load example history as a torch.Tensor shaped [variables, time].
history = ci.load_example()

# Forecast the next 24 hourly time steps.
prediction = model.forecast(history, horizon=24)

# Plot the forecast and its uncertainty bands.
ci.plot_forecast(history, prediction, model.quantiles, output="forecast.png")
```

forecast and nested quantile bands.](assets/readme/bike_sharing_forecast.png)

**The next 24 hours, with uncertainty included.** The shaded region marks the forecast
day. The curve shows the model's median forecast, surrounded by nested quantile bands.
Replace the example history with your own to get started.

**Dive deeper.** The [walkthrough notebook][walkthrough] extends this example with calendar
covariates, practical uses of the quantiles, and forecasting through missing data.

## Frontier performance

**The #1 foundation model on fev-bench.**

## Talk to the team

**Tell us what you need to predict.** We want to hear about the decisions you're trying to
improve, the data you're working with, and where current methods fall short.

Whether you're exploring a new idea or improving an existing system, we'd like to work
with you on a solution. Share your use case, your constraints, and what success would look
like, and let's discuss how we can help.

## Beyond ci-proto

**Frontier performance is our starting point.** ci-proto gives you a first look at our
approach to time-series intelligence. Our next release builds on that foundation.

## Usage details

Covariates, categorical inputs, timestamps, related series, revision pinning, and CPU and
GPU setup are documented in the [package README](https://github.com/continuousintelligence/ci#usage-details).

## Model details

- **Developed by:** Continuous Intelligence Limited
- **Model type:** pretrained time-series foundation model for zero-shot probabilistic forecasting
- **Parameters:** 167M
- **Inputs:** one or more target series, with optional past and future covariates, timestamps and related series
- **Outputs:** nine quantiles from 0.1 to 0.9 for every target and forecast step
- **Files:** `model.ckpt` (histories up to 16,384 steps), `model-long.ckpt` (longer histories, selected
  automatically), `tta.json` (preprocessing and calibration settings) and `config.json` (model information)

## Training and evaluation

- **Training data:** a large corpus of real-world and synthetic time series.
- **Evaluation:** zero-shot on all 100 tasks of [fev-bench](https://huggingface.co/spaces/autogluon/fev-leaderboard),
  with the released preprocessing and calibration in `tta.json`, scored by scaled quantile loss.

## Licence

The model weights are released under the [ci-proto Code and Model Licence](LICENCE).
