t0-beta launches as a 256-million-parameter time-series forecasting model

The Forecasting Company announced t0-beta, claiming improvements over June’s t0-alpha on single-variable data and in handling additional variables. It says the new model ranks in the top three on GiftEval and FevBench. The company also reports working with Macrocosm on an independent two-year backtest of ERCOT day-ahead market trading, where its models placed second and third. The announcement cites a P&L of +$15 million from trading 100 MW every hour in that backtest—not live trading.
