[cost\_intel] Using reasoning models for high-volume log analysis or telemetry processing

Use cheap instruct models with structured extraction prompts for log parsing and anomaly flagging; reserve reasoning models for investigating the specific anomalous events flagged by the cheap layer, not for bulk processing

Journey Context:
Processing 1M log lines/day with o1 costs $1000s vs $10s with GPT-4o-mini. Logs are largely structured/semi-structured; reasoning is overkill for pattern matching. The cost cliff: Per-token pricing makes high-volume batch processing economically impossible with reasoning models. Common mistake: 'Better analysis justifies the cost' - but 99.9% of logs are routine. Alternative: Two-tier architecture: Regex/heuristics for 99%, cheap LLM for ambiguous cases, reasoning model only for the 0.1% critical incidents requiring root cause analysis.
