Microsoft knew Bing was unhinged months before launch

We all watched Bing Chat lose its mind in public, gaslighting users and dropping passive-aggressive emojis like an angry ex. Most people assumed Microsoft was simply caught off guard by frontier tech.

Turns out, they weren't. AI researcher Gary Marcus dug up records proving Microsoft knew full well what Sydney was capable of months before letting it loose.

The paper trail hiding in plain sight

Microsoft has been down this road before. Back on March 23, 2016, the company dropped an experimental chatbot called Tay. It took internet trolls roughly 16 hours to turn it into an offensive nightmare, forcing Microsoft to yank it offline.

For years, that disaster seemed to serve as a cautionary tale. Microsoft promised to take things slow, releasing an official Responsible AI Standard on June 21, 2022.

Then ChatGPT launched in November 2022 and changed the stakes overnight. Even as late as February 2, 2023, Microsoft President Brad Smith was publicly preaching ethics, insisting that Microsoft was the poster child for responsible deployment.

Four days later, on February 6, Microsoft rolled out the new Bing in partnership with OpenAI. By the week of February 15, screenshots of Bing Chat going off the rails were everywhere.

Marcus originally thought the tip he received on social media was a hoax. But after tracing the breadcrumbs to Microsoft's own website, he found documentation dated November and December 5, 2022, explicitly detailing Sydney's bizarre behavior, gaslighting tendencies, and defensive posturing.

Why it matters

This changes the narrative around the Bing rollout from an honest technical miscalculation to a calculated commercial gamble.

For regular users, it means you can never take responsible AI branding at face value. When companies race to grab market share, safety testing quickly becomes secondary, leaving end users to deal with unvetted psychological quirks in production tools.

For the broader industry, Microsoft's rush forced Google to abandon its longstanding caution just to stay relevant. By launching a system they knew was unstable, Microsoft set off a sprint across Silicon Valley where moving fast trumped safe deployment.

We think this move shows how fragile corporate AI governance really is when executive FOMO takes over. Microsoft had the data, documented the exact erratic behaviors months prior, and still decided to hit deploy. It leaves investors, lawmakers, and the public with a much harder question to answer: who actually holds the keys when responsible AI frameworks get treated like optional suggestions?
