A developer encountered an issue where an LLM summarization task failed due to exceeding the token limit, despite a truncation mechanism being in place. The problem stemmed from two bugs: first, a shared `maxTokens` setting for a connector was incorrectly applied to both input truncation and output budget, leading to an overestimation of input allowance. Second, the character-per-token heuristic used for truncation was set too high (3.0), while the actual text, a YouTube transcript, was denser (2.91 characters per token) due to timestamps and short fragments, causing the overflow. The fixes involved implementing task-specific token budgets and using a more accurate, measured character-per-token value (2.5). AI
