Los Angeles radio station José FM has turned to large language models to stay competitive, launching a live AI co-host named Coyotec that is driving listener engagement while sparking fierce debate among human broadcasters. The AI, voiced by ElevenLabs using the vocal profile of Entravision Audio president Eduardo Maytorena, works alongside human DJ Geraldine "GeeGee" Guzman. Since going live in May, the hybrid format has moved from weekend slots to prime-time weekday commutes, expanding to markets including Sacramento, Las Vegas, and El Paso.

The Tech Stack Behind the Banter

Unlike fully automated overnight slots seen at other stations like 94.9 The Zone in Phoenix, Coyotec operates in a semi-automated loop that requires human oversight. Guzman uploads specific news topics and prompts to the AI's software, which then generates "hot takes" on subjects ranging from the Dodgers to ICE raids. The system is not without its bugs; the AI occasionally swears despite programming guardrails and struggles to maintain coherent voice conversations longer than 10 minutes. To manage this, Guzman records each of the four broadcast segments separately, editing around the AI's limitations to keep the flow natural.

The Economics of Synthetic Audio

The deployment comes as the radio industry contracts, with Bureau of Labor Statistics data showing a 22% decline in broadcasting jobs between 2019 and 2025. Major operators like iHeartMedia and Audacy have cut local DJs to reduce costs. However, José FM executive Eduardo Maytorena argues that AI is a revenue multiplier, not just a cost-cutter. He claims the ability to program verbatim ad pitches generates ten times the return for every dollar spent on the technology, noting that developing and running the AI DJ actually cost more than some human hires.

Union Resistance and Labor Concerns

Despite the financial upside for management, labor groups are pushing back. SAG-AFTRA has condemned the use of "synthetic substitutes," arguing that AI erodes public trust and undermines the livelihoods of professionals who deliver authenticity. The union hopes to convince large media organizations to limit AI use, positioning the technology as a threat to the human connection that defines the medium.

The Trust Deficit

Critics argue that while AI can mimic the cadence of a trusted friend, it lacks the embodied knowledge and stakes that make radio personal. Sam Gregory, a synthetic media expert at American University, warns that listeners are building relationships with a "predictive text machine," which could be dangerous if audiences stop distinguishing between human empathy and algorithmic output. John DeSantis, a DJ who lost his job at 96.5 KCAL-FM last month, asserts that AI cannot replicate the authentic connection of live, local hosting. Meanwhile, iHeartMedia has launched a "Guaranteed Human" campaign to appeal to listeners who still value human interaction over synthetic efficiency.

Key Takeaways

  • José FM's AI co-host Coyotec uses ElevenLabs voice cloning and LLMs to generate live commentary, requiring human DJ GeeGee Guzman to manage segment lengths and content prompts.
  • The AI format has expanded to multiple markets and moved to prime time, with executives claiming a 10x ROI on ad revenue despite higher development costs than some human hires.
  • Unions like SAG-AFTRA and displaced human DJs argue that AI erodes trust and authenticity, citing a 22% drop in broadcasting jobs since 2019 as evidence of industry contraction.

The Bottom Line

AI is no longer just a backend tool for scheduling; it is becoming a front-end product, and the tech community must decide if efficiency is worth the cost of human trust.
