⚙️ Performance optimization Tabnine includes settings to balance performance and features, allowing users to disable certain capabilities when working on resource-constrained systems.

Privacy and Security Features

🛡️ Deployment flexibility Tabnine offers multiple options to accommodate different security requirements:

• SaaS deployment: Standard cloud-based service with zero data retention policy
• VPC deployment: Within customer’s Virtual Private Cloud
• On-premises deployment: Complete isolation within organization’s infrastructure

🔐 Data handling approach With the SaaS option, information sent to Tabnine’s inference servers is “encrypted in transit, runs only in memory, and is deleted after delivering the response.”

⚖️ IP protection guarantee Tabnine’s proprietary models are trained exclusively on permissively licensed code, providing “guaranteed protection against legal liabilities” related to IP violations without post-generation filtering requirements.

📋 Model choice tradeoffs Users can choose from eight AI models with varying privacy levels. Models like Claude 3.5 Sonnet and GPT-4 Turbo lack the same data privacy guarantees and IP protection as Tabnine’s Protected models.

Code Suggestion Quality and Accuracy

🎯 Suggestion capabilities Tabnine excels at predicting common patterns and completing standard programming constructs, including function calls, variable names, logical next steps, and boilerplate code.
