short_description: Probabilistic stock forecasting with Kronos

Kronos Filter — Probability API

Remote compute backend for kronos-filter.vercel.app.

This Space wraps the Kronos foundation model into a REST API that returns probabilistic stock forecasts.

Usage

Via UI (this page)

Fill in tickers and parameters below, click "Predict".

Via API

from gradio_client import Client

client = Client("Kurtobe/kronos-filter")
result = client.predict(
    tickers_raw="MSFT, NVDA, AAPL",
    lookback=400,
    pred_len=30,
    samples=30,
    seed=42,
    api_name="/predict"
)

Or via HTTP (two-step):

# Step 1: submit
curl -X POST https://kurtobe-kronos-filter.hf.space/call/predict \
  -H "Content-Type: application/json" \
  -d '{"data": ["MSFT,NVDA", 400, 30, 30, 42]}'
# → { "event_id": "..." }

# Step 2: stream
curl https://kurtobe-kronos-filter.hf.space/call/predict/{event_id}

Model

• Kronos-small (24.7M params, 512 context)
• Tokenizer: Kronos-Tokenizer-base
• Runs on ZeroGPU (A10G, dynamically allocated per request)
• Typical inference: 5-15 seconds for 3-10 tickers × 30 samples
• First request cold-start: ~15s (model load onto GPU)
• Free HF account daily quota: ~5-10 GPU-minutes

Disclaimer

Not financial advice. The returned probabilities are model-subjective — the internal distribution of Kronos's sampled paths — not real-world probabilities.
