Jev, Firecrawl & the $1B rev club
Brex hosts three AI-related events this week and highlights Jev, a new model by Typesafe AI, as a solution to save money on token spending. Jev complements existing LLMs, such as OpenAI and Anthropic, by acting as a security guardrail to verify proposed system actions. Brex showcases Jev's capabilities through an example of an automated security guardrail for an AI customer support agent.

Jev, Firecrawl & the $1B rev club
Happy Tuesday, Brex Community!
There are three AI related events that Brex is hosting this week, see bottom of the email for specific details.
On a AI related note. The current trend is trying to save money on token spending and the most wide discussed solution the past two weeks is Jev, which is a new model released by Typesafe AI on Sept 15. For those who are unfamiliar, Jev is not competing directly against existing LLMs such as OpenAI and Anthropic, it is complementary to them. Here is an example:
A common enterprise use case for Jev is acting as an automated security guardrail for an AI customer support agent. In this setup, the LLM handles the conversation, while Jev strictly verifies the LLM's proposed system actions before they are allowed to execute. Here is how the interaction flows when a customer asks a support chatbot for a refund:
The User Request: A customer tells the chatbot, "I meant to pause my subscription, but I got charged today. Please refund my payment."
The LLM (The Communicator): The LLM reads the message, drafts a polite reply, and generates a system command to trigger the company's billing software: issue_refund(amount: $15.00).
