Alice has partnered with Inflection AI and AI21 to post-train and fine-tune NVIDIA Nemotron models for enhanced safety and security. These projects utilize an adversarial database to mitigate risks like sycophancy and indirect prompt injection in large-scale language models.
Why it matters
As open-weight models become industry standards, the ability to adapt them for compliance and security without degrading performance is critical for enterprise adoption. This effort targets the specific vulnerability of personal AI agents to manipulation.
Fine-tuning on an adversarial database increased Pi's alignment score by 30% while maintaining unnecessary refusal rates at 1.6%. Resilience against indirect prompt injection improved by 41 points across NVIDIA Nemotron 3 120B and 3.5 Super VL architectures.
The players
Alice
An AI security firm focused on red-teaming, reinforcement learning, and safety alignment for large language models.
Inflection AI
A developer of personal AI agents, known for the Pi product and research into conversational alignment.
AI21
An AI company specializing in natural language processing architectures and open-weight model development.
NVIDIA
A hardware and software provider whose Nemotron models serve as the foundational architecture for these safety projects.
The details
Alice uses red-teaming datasets—structured adversarial tests designed to uncover model weaknesses—alongside 20 distinct personas to stress-test multi-turn interactions. By building reinforcement-learning environments, the team trains models to identify and neutralize malicious injection attempts while maintaining functional task execution. These techniques are designed to sanitize model responses against sycophancy, the tendency of models to prioritize user agreement over factual accuracy.

The Tech Race
This work aligns with the industry-wide push to standardize safety benchmarks for open-weight architectures, mirroring the rigor of the 2023 NIST AI Risk Management Framework. It marks a departure from purely academic safety research by integrating these fixes directly into production-grade personal AI.
Users of the Pi personal AI will experience more consistent, non-manipulable interactions following the 30% alignment gain. Developers building on NVIDIA Nemotron models can now leverage these post-training techniques to harden their own deployments against common prompt injection vectors.
The takeaway
Securing open models against adversarial manipulation is now a quantifiable engineering discipline rather than a theoretical goal. Watch for future performance benchmarks released for the Nemotron 3.5 series as developers apply these red-teaming techniques to broader enterprise use cases.
