## What the models said about Fluent Bit

- "these are signal-specific, not full pipelines like modern ones" (Grok 4.1 Fast, comparative prompt, soft negative)
- "Use a dedicated pipeline (e.g., OpenTelemetry Collector, Fluent Bit) for filtering, sampling, redaction, enrichment upstream before backends." (Grok 4.1 Fast, negative prompt, first choice)
- "I'd recommend starting with Vector or Fluent Bit." (MiniMax M2.5, paraphrase prompt, first choice)
- "Running Kubernetes and want lightweight log collection | Fluent Bit (agent) + Vector (aggregator)" (DeepSeek V4 Flash, paraphrase prompt, alternative)
