We break down the background behind why Claude intermittently experiences performance degradation or errors, and the response strategies users should consider.
Imagine this: You ask your AI assistant ‘Claude’ to summarize important meeting notes this morning, just like you always do. But Claude, usually so reliable, suddenly gives a nonsensical answer or stops responding entirely with an error message. It’s a frustrating moment, to be sure. Recently, many users have been experiencing intermittent performance drops with Claude. Why is this happening?
Why does this matter?
We no longer view AI as just a toy; it has become a reliable companion for our actual work and daily lives. We rely on AI to write code, compose text, and analyze complex data. But what happens when the AI we count on suddenly stops working properly? It’s more than just an inconvenience; it can lead to a significant drop in productivity and disrupt important decision-making. Reference 13 For developers and paid subscribers, this essentially makes the tool untrustworthy. Reference 14
Easy to understand
AI models like Claude operate within massive “brain” servers. This brain needs to perform countless complex calculations to think and produce results.
Let’s compare this process to a “restaurant run by a famous chef.”
- The AI model is the excellent dish served to the customer.
- The inference stack (the infrastructure where AI processes data) is the kitchen system that prepares the meal.
Sometimes, while trying to upgrade the kitchen system to make it faster, a chef might accidentally mix up ingredients or fail to regulate the gas flame, causing the dish to burn. Reference 19 If the entire system shifts even slightly, the user experiences the AI feeling less intelligent than before (quality degradation), responding slower (latency), or failing to answer entirely (errors). Reference 12
Current situation
Claude’s performance degradation is not limited to specific services. It has been reported intermittently across the entire Claude ecosystem, including the web environment (claude.ai), development tools (Claude Code), and API services. Reference 3, Reference 4
Looking at historical cases, a performance crisis in August 2025 lasted for about six weeks, affecting 30% of all users and eventually leading to a “great migration” where users left for other AI services. Reference 18 Recently, instances of performance degradation coupled with a higher error rate on requests have been observed, prompting Anthropic to take resolution measures. Reference 2, Reference 12
Concerns about “model degradation”—the feeling that the AI has become “dumber” than before—are also consistently being raised among users. Reference 14, Reference 15
What’s next?
As AI technology advances, systems will inevitably become more complex, and moments of instability will occur again. Therefore, for those who deeply integrate AI into their work, the following response strategies are needed when systems become unstable:
- Check Service Status: If a problem occurs, check the official status page from Anthropic (status.claude.com). Reference 1
- Multi-Model Strategy: Do not rely blindly on a single AI. It is safer to have a “Plan B” in place where you can immediately switch to another AI model (e.g., ChatGPT) in the event of a service outage. Reference 18
- Technical Preparation: If you are building apps using APIs, it is essential to design a system that includes automatic retry logic in case of errors or implements load balancing. Reference 12
MindTickleBytes AI Reporter’s View
Fluctuations in AI model performance may be a part of the growing pains of the technology. However, since users pay for these services, companies must be transparent in sharing the situation and exert all efforts toward building more robust systems. Users, too, need the wisdom to recognize that no technology is perfect and to respond flexibly.
