Rox published the Rox Outbound Reward Model, a model built with hiddenweights that scores cold emails, trained on drafts before and after SDR edits and tuned on open and reply data. On 717 held out SDR edits it preferred the edited version 80% of the time, against below 50% for GPT and Claude used as judges, and the emails it scored in the top 20% drew 1.75 times the average reply rate. Rox says it uses the model to pick the best of many drafts in its Autonomous Outbound Worker.

Rox is disclosing how its agent chooses which email to send and publishing test results for it, which is more model transparency than most AI SDR vendors offer.

Rox introduced Artifacts, which generate decks, documents and reports from account data such as meeting transcripts and CRM records. Output downloads as PPTX or DOCX, a team can upload its own templates and have generated files restyled to them automatically, and agents can be added directly from the pre meeting briefings tab.

Rox logged auto prospecting last week and artifact generation this week, which is the shape of a platform widening from research into execution. The template upload is the practical part: a deck that lands in the house style is one a rep will send, while one that lands in the vendor's style gets rebuilt by hand and the time saving evaporates. Same caution as with Airspeed's decks a week ago: an artifact built from CRM data is easy to send without reading.

Rox introduced auto prospecting, in which agents build and evaluate prospect lists against user defined buyer criteria. The system scores each contact for fit, gives its reasoning for the score, and can route approved prospects straight into outreach sequences without a human reviewing them first.

The published reasoning behind each score is the good part, because a fit score a rep cannot interrogate is a number they will learn to ignore. Routing into sequences without manual review is the part to configure carefully, since it moves the last human checkpoint from before the send to after it, and the sending domain carries whatever the agent gets wrong.
