The paper introduces FWBench, a benchmark for assessing how language models choose and employ time‑series forecasts under budget constraints. Using 1,251 electricity and cycle‑hire cases, the study evaluates agents that select models, histories, and horizons to submit capacities that minimize a loss‑cost objective. Experiments with both hosted and local configurations—including small language models and TSFMs—show that GPT‑6 Astra can achieve superior performance by selectively buying inexpensive short‑horizon forecasts, using only 2.5% of the budget.
arXiv:2508. 09904v3 Announce Type: replace-cross Abstract: Real-world forecasting requires models to integrate not only historical data but also relevant contextual information provided in textual form.
Real-world time-series forecasting is rarely a one-shot model invocation: practitioners must formulate tasks, connect data and models, incorporate domain expertise, assess prediction plausibility, and...

arXiv:2604. 22328v2 Announce Type: replace-cross Abstract: Driven by the transition towards a climate-neutral energy system, accurate energy time series forecasting is critical for planning and operations.
Text-conditioned time-series forecasting predicts a series from both its numerical history and natural-language context, allowing forecasts to account for events and constraints that the past alone cannot reveal. This requires both reliable numerical forecasting and the ability to interpret contextual information.
District heating energy hubs require reliable heat load forecasts for efficient operational scheduling. Conventional forecasting workflows train system-specific models on historical data, which can become burdensome when networks change through new consumers, retrofits, or changing operating regimes.
