Pros and cons
🧠
NotebookLM
Research · freemium

- ✓Fast Research and Deep Research can add web sources to the notebook
Cons
- ×The free plan caps you at 100 notebooks and 50 sources per notebook

Fugu-Cyber
Research · paid
Pros
- ✓Specialized for cybersecurity rather than a general model used off-label
- ✓Claimed SOTA on real-world benchmarks (CyberGym, CTI-REALM), not just synthetic tests
- ✓Orchestration design targets multi-step agentic security workflows
- ✓Application-gated rollout is a reasonable posture for offensive-security capability
Cons
- ×Access is gated behind application approval with no free tier or public playground
- ×Performance claims come almost entirely from Sakana's own release — little independent verification yet
- ×Output pricing is steep and scales higher for large-context requests
- ×Narrow specialization: not useful outside security work
