In a significant blow to British AI startup Stability AI, key members of the artificial intelligence research team behind the groundbreaking Stable Diffusion text-to-image generation model have resigned, as reported by Forbes. The news was delivered by CEO Emad Mostaque during an all-hands meeting last week, according to sources familiar with the situation. The departing researchers include Robin Rombach, who led the team, as well as Andreas Blattmann and Dominik Lorenz - all three of whom were instrumental in developing the core Stable Diffusion research while at a German university.

Their resignations mark the latest in a series of setbacks for Stability AI, which has been grappling with a significant exodus of executives amid financial struggles and difficulty raising additional funds. The company, which once attracted major tech investment firms such as Coatue and Lightspeed, has seen its cash reserves dwindle as its spending on wages and compute power surpasses revenue, according to documents seen by Forbes. Bloomberg previously reported that Stability AI was spending $8 million per month.

The now-departed research team played a crucial role in the success of Stability AI, with their Stable Diffusion model generating AI images that went viral and contributed greatly to the generative AI craze. This enabled CEO Emad Mostaque to secure over $100 million in investments within days of the launch. A portion of these funds was used to hire Rombach, Blattmann, and Lorenz from their previous positions, keeping Stability AI at the forefront of technical innovations in generative AI imagery.

However, the resignations of Rombach and his team now add to Stability AI's growing list of high-profile technical departures. Over the past year, the company has seen several vice presidents, research chiefs, and other senior executives leave, creating a significant leadership vacuum. Vice presidents Christian Cantrell, Scott Draves, Patrick Hebron, and Joe Penna all departed, alongside notable figures such as research chief David Ha and LLM leads Stanislav Fort and Louis Castricato.

The financial strain on Stability AI has resulted in Coatue resigning from the board and Lightspeed Venture Partners relinquishing its board observer seat. Coatue reportedly called for CEO Emad Mostaque's resignation and urged the company to pursue a sale. However, Stability AI denied such intentions and emphasized Mostaque's instrumental role in the company's success. In a bid to alleviate their financial woes, Stability AI raised $50 million from semiconductor giant Intel in the form of a convertible note.

Stability AI's troubles extended beyond financial struggles. The company recently sold off Clipdrop, an image generating and editing platform, to AI startup Jasper. Additionally, concerns were raised over the company's ability to pay wages and payroll taxes, with reports suggesting blurred lines between Mostaque, his wife, and the company's finances. Stability AI denied allegations that cloud compute provider Amazon Web Services threatened access revocation due to unpaid bills.

As Stability AI continues to grapple with internal challenges and a weakened financial position, rival AI image generation company Midjourney blamed a 24-hour outage on "botnet-like activity" attributed to two user accounts linked with Stability AI employees. In response, Midjourney announced a ban on Stability AI employees and anyone engaging in aggressive automation to scrape prompts from their service.

The departure of key research team members highlights the mounting obstacles faced by Stability AI. The loss of their expertise and the ongoing leadership vacuum could impede the company's ability to stay at the forefront of generative AI innovations, placing its future in a precarious position.
