Integrate GPT-5 Pro with Hybrid Reasoning and RAG

Integrate GPT-5 Pro (or `gpt-4o`) into your agents. For the 'IoC Extraction & Enrichment' agent, implement hybrid reasoning: use 'Instant Think' for basic parsing of log entries, but switch to 'Deep Think' mode for complex natural language descriptions of suspicious files or intricate network patterns. Also, implement RAG to query a simulated threat intelligence vector database (e.g., for MITRE ATT&CK techniques) for context on extracted IoCs.
