Strix AI pentesting tool now runs on 400+ models via Vercel AI Gateway

October 29, 2026Source: Vercel

Strix, the open-source AI penetration testing tool, can now run on any of the 400+ models available through Vercel AI Gateway, according to a Vercel changelog entry. The integration lets users reach models from several providers through one API without signing up separately with each.

Key points

Strix, an open-source AI penetration testing tool, now supports Vercel AI Gateway.
Users can run any of the 400+ models in AI Gateway, including ones from Anthropic, OpenAI, Kimi, GLM and Deepseek.
Vercel says access is through a single API with no markup and no need to sign up with multiple providers.
Usage and cost across all models are tracked in AI Gateway.
Setup uses the STRIX_LLM variable with a vercel_ai_gateway/ prefix and an LLM_API_KEY.

One API for many model providers

According to Vercel, Strix can now reach models from Anthropic, OpenAI, Kimi, GLM, Deepseek and others through a single API. Vercel says this comes with no markup, and that it removes the need to register with multiple providers.

For a security tool that relies on large language models, this changes how a model is chosen. A team can pick from the models offered in AI Gateway without setting up a separate account and key for each vendor.

Usage and cost tracking

Vercel states that usage and cost are tracked across all models in AI Gateway. Instead of reconciling separate bills and dashboards from different providers, users see consumption for every model they run through Strix in one place.

How to configure it

Strix selects the Gateway through the STRIX_LLM environment variable. The model is given as the standard AI Gateway <provider>/<model> ID, placed behind a vercel_ai_gateway/ prefix. A second variable, LLM_API_KEY, holds the AI Gateway API key.

The example in Vercel's announcement uses two terminal commands:

export STRIX_LLM="vercel_ai_gateway/zai/glm-5.3"
export LLM_API_KEY="your-ai-gateway-api-key"

Vercel points users to Strix's AI Gateway setup guide for the full configuration steps.

What it means for users

For people running Strix, the change widens the choice of models behind the tool and simplifies account management, based on Vercel's description. Switching models comes down to changing the model ID in STRIX_LLM, while billing and usage stay in AI Gateway. The announcement does not include pricing details or performance comparisons between models, so users will need to test which model suits their own security testing work.
