ChatGPT, Claude down? Simultaneous outage hits major AI platforms

Users of major artificial intelligence platforms faced widespread disruption on Thursday as OpenAI’s ChatGPT, Anthropic’s Claude and Google’s Gemini reportedly experienced service issues, triggering frustration across social media and disrupting everyday work for developers, students, researchers and office teams.

Anthropic confirmed that Claude was experiencing elevated errors across several models and said it had identified the underlying issue and was working on a fix. The incident affected both the Claude consumer service and API, with reports indicating disruption to Claude AI, Claude Code and Claude Cowork.

Users report simultaneous failures

The overlap in reported outages quickly became a talking point on X, formerly Twitter, where users shared screenshots, error messages and jokes about suddenly losing access to their preferred AI tools. Downdetector also showed a sharp rise in user-submitted incident reports, signalling that the problem was affecting more than isolated accounts.

“Both Claude and ChatGPT are down. Makes you wonder if people were moving to ChatGPT because Claude is down and that caused an overload to ChatGPT...,” a user wrote in X.

Others expressed a mix of panic and humour as their primary daily workflows came to an abrupt halt. A user wrote on X, “ChatGPT and Claude both are down, what am I supposed to do now?”

Claude outage affects users

Claude users reported issues with chat access, coding workflows and API-based tools. Reports on Thursday indicated that the largest concentration of complaints involved Claude Code and Claude Chat, while Anthropic’s status information identified elevated errors across multiple models.

The incident highlights how heavily professionals now rely on generative AI platforms for programming, writing, research, customer support and daily productivity tasks. When several major providers encounter trouble at the same time, users have fewer practical fallback options.

Is ChatGPT down?

OpenAI has previously acknowledged incidents involving elevated latency and partial ChatGPT outages, including cases in which users could not start or continue work in ChatGPT Work. However, simultaneous user reports alone do not establish that one provider’s outage caused another’s.

There is currently no verified evidence that traffic shifting from Claude to ChatGPT directly triggered a ChatGPT outage. High traffic, infrastructure failures, software changes, third-party service dependencies and regional network problems can each cause service disruptions independently.

Google Gemini issues

Google Gemini was also reported by some users as experiencing problems during the broader wave of AI-service complaints. With all three platforms reportedly affected, users searching for alternatives found that switching assistants did not always restore access immediately.

For real-time verification, users should check the official status dashboards for OpenAI, Anthropic and Google rather than relying only on social-media posts or outage-tracker submissions.
