🌍 New release: Twelve Data World Model Dataset
We just open-sourced a financial dataset shaped for training world models, fine-tuning LLMs, and offline reinforcement learning.

📦 What's in it
• 51 large-cap US equities
• 3 timeframes: 1day, 1h, 1min
• 3 output views per timeframe:
— bars: OHLCV + 19 causal indicators + macro joins
— text: instruction-tuning JSONL
— trajectories: (state, next_state) windows
• Macro context joined per row: SPY, VIX, TLT, DXY, sector ETFs
• Time-based splits: train ≤ 2023, val = 2024, test = 2025+

✅ Why it's different
• Causal correctness enforced with unit tests — no leakage from
future bars
• Auto-updated daily; corporate-action handling rebuilds adjusted
history automatically
• Full pipeline open source, not just the data
• Three output formats for three workflows — pick what fits your model
