```
-## Models
+## Input/Output Format
-### FlowState
+### Input Data Format
+
+**All models require 3D input arrays:**
+
+```python
+# Shape: (batch_size, sequence_length, features)
+x = np.array([
+ [[1.0], [2.0], [3.0]], # Series 1
+ [[4.0], [5.0], [6.0]] # Series 2
+]) # Shape: (2, 3, 1)
+```
+
+- **batch_size**: Number of independent time series
+- **sequence_length**: Historical data points (context window)
+- **features**: Number of variables per time step (use 1 for univariate)
+
+**Important**: 2D input will raise a validation error. Always provide 3D arrays.
+
+### Output Data Format
+
+**Point Forecasts** (3D):
+```python
+response.point # Shape: (batch_size, horizon, features)
+```
+
+**Quantile Forecasts** (4D):
+```python
+response.quantiles # Shape: (batch_size, horizon, num_quantiles, features)
+# Example: (32, 24, 5, 1) = 32 series, 24 steps ahead, 5 quantiles, 1 feature
+```
+
+### Univariate vs Multivariate
+
+- **Chronos2**: โ
Supports multivariate forecasting (multiple features)
+- **FlowState**: โ ๏ธ Univariate only - automatically transforms multivariate input
+- **TiRex**: โ ๏ธ Univariate only - automatically transforms multivariate input
+
+When you provide multivariate input (features > 1) to FlowState or TiRex, the SDK automatically:
+1. Issues a warning
+2. Forecasts each feature independently
+3. Reshapes the output back to your original structure
+
+```python
+# Multivariate input to FlowState
+data = np.random.randn(2, 100, 3) # 2 series, 3 features
+request = FlowStateForecastRequest(x=data, horizon=24, prediction_type="mean")
+
+# Warning: "FlowState model only supports univariate forecasting..."
+response = client.forecast(request)
-Point forecasting model optimized for deterministic predictions.
+# Output is automatically reshaped
+print(response.point.shape) # (2, 24, 3) - original structure preserved
+```
+

```
-## Async Usage
+## Evaluation & Metrics
+
+The SDK includes a comprehensive evaluation toolkit (`faim_sdk.eval`) for measuring forecast quality with standard metrics and visualizations.
+
+### Installation
+
+For visualization support, install with the viz extra:
+
+```bash
+pip install faim-sdk[viz]
+```
+
+### Available Metrics
+
+#### Mean Squared Error (MSE)
+
+Measures average squared difference between predictions and ground truth.
```python
-async with ForecastClient(base_url="http://localhost:8003") as client:
- response = await client.forecast_async(ModelName.FLOWSTATE, request)
- print(response.point)
+from faim_sdk.eval import mse
+
+# Evaluate point forecast
+mse_score = mse(test_data, response.point, reduction='mean')
+print(f"MSE: {mse_score:.4f}")
+
+# Per-sample MSE
+mse_per_sample = mse(test_data, response.point, reduction='none')
+print(f"MSE per sample shape: {mse_per_sample.shape}") # (batch_size,)
```
-## Examples
+#### Mean Absolute Scaled Error (MASE)
+
+Scale-independent metric comparing forecast to naive baseline (better than MAPE for series with zeros).
+
+```python
+from faim_sdk.eval import mase
+
+# MASE requires training data for baseline
+mase_score = mase(test_data, response.point, train_data, reduction='mean')
+print(f"MASE: {mase_score:.4f}")
+
+# Interpretation:
+# MASE < 1: Better than naive baseline
+# MASE = 1: Equivalent to naive baseline
+# MASE > 1: Worse than naive baseline
+```
+
+#### Continuous Ranked Probability Score (CRPS)
+
+Proper scoring rule for probabilistic forecasts - generalizes MAE to distributions.
+
+```python
+from faim_sdk.eval import crps_from_quantiles
+
+# Evaluate probabilistic forecast with quantiles
+crps_score = crps_from_quantiles(
+ test_data,
+ response.quantiles,
+ quantile_levels=[0.1, 0.5, 0.9],
+ reduction='mean'
+)
+print(f"CRPS: {crps_score:.4f}")
+```
+
+### Visualization
+
+Plot forecasts with training context and ground truth:
+
+```python
+from faim_sdk.eval import plot_forecast
+
+# Plot single sample (remember to index batch dimension!)
+fig, ax = plot_forecast(
+ train_data=train_data[0], # (seq_len, features) - 2D array
+ forecast=response.point[0], # (horizon, features) - 2D array
+ test_data=test_data[0], # (horizon, features) - optional
+ title="Time Series Forecast"
+)
+
+# Save to file
+fig.savefig("forecast.png", dpi=300, bbox_inches="tight")
+```
+
+#### Multi-Feature Visualization
-See the `examples/` directory for complete notebook examples:
-- `flowstate_simple_example.ipynb` - Point forecasting with FlowState
-- `toto_simple_example.ipynb` - Probabilistic forecasting with ToTo
+```python

+ train_data[0],
+ response.point[0],
+ test_data[0],
+ features_on_same_plot=True,
+ feature_names=["Temperature", "Humidity", "Pressure"]

+## Async Support
+
+The SDK supports async operations for concurrent requests:

+```python
+import asyncio

+ Chronos2ForecastRequest(x=data3, horizon=24),
+ ]
+
+ # Execute concurrently
+ async with client:
+ tasks = [
+ client.forecast_async(req)
+ for req in requests
+ ]
+ responses = await asyncio.gather(*tasks)

-### Regenerating the Low-Level Client
+1. **Batch Processing**: Process multiple time series in a single request for optimal throughput
+ ```python
+ # Good: Single request with 32 series
+ data = np.random.randn(32, 100, 1)
-The `faim_client` package is auto-generated from the OpenAPI specification. To regenerate after API changes:
+ # Less efficient: 32 separate requests
+ # for series in data: client.forecast(...)
+ ```
-```bash
-# Get the latest OpenAPI spec from your server
-curl http://your-server:8003/openapi.json > openapi.json
+2. **Compression**: Use `compression="zstd"` for large payloads (default, recommended)
-# Regenerate the client
-openapi-python-client generate --path openapi.json --config client.config.yaml --meta none
-```
+3. **Async for Concurrent Requests**: Use `forecast_async()` with `asyncio.gather()` for parallel processing
-The `--meta none` flag prevents creating an extra outer directory.
+4. **Connection Pooling**: Reuse client instances across requests instead of creating new ones
-After regenerating, test that `faim_sdk` still works correctly:
-```bash
-poetry install
-pytest tests/
-```
