Is Claude 3.5 Sonnet Getting Dumber? You Might Not Be Hallucinating
In recent weeks, there has been growing concern among users of Claude 3.5 Sonnet that the AI assistant’s capabilities seem to be degrading. Numerous reports on social media and forums describe Claude giving less coherent responses, making more mistakes, and generally performing worse than it did previously.
While some dismiss these claims as mere perception bias, there is mounting evidence that Claude may indeed be “getting dumber” in certain ways. This article will examine the situation, explore potential causes, and offer some recommendations for users.
The Symptoms: How Claude Seems to be Declining
Users have reported a variety of issues that suggest Claude’s performance is slipping:
- Less coherent responses: Claude’s outputs sometimes lack logical flow or contain non-sequiturs.
- Increased errors: More factual mistakes and incorrect information in responses.
- Difficulty with complex tasks: Struggling with multi-step problems it previously handled well.
- Repetition and hallucination: Repeating itself or making up false information more frequently.
- Degraded code generation: Producing buggy or nonsensical code, especially for larger projects.
- Inconsistent performance: Wide variation in quality of responses to similar prompts.
Many long-time Claude users insist these issues were not present (or were much less common) when they first started using the 3.5 Sonnet model. The degradation seems to have occurred gradually over time rather than as an abrupt change.

Potential Causes: Why Might Claude Be Declining?
There are several theories about what could be causing Claude’s apparent performance issues:
Quantization and Model Compression
One possibility is that Anthropic has applied quantization or other model compression techniques to Claude.
- This involves reducing the precision of the model’s parameters to shrink its size and computational requirements. While this can make the model more efficient to run, it often comes at the cost of some accuracy and capability.
- OpenAI took a similar approach with GPT-4, creating the more lightweight GPT-4 Turbo and GPT-4–0125 models. These compressed versions trade some performance for increased speed and lower resource usage. Anthropic may be experimenting with similar optimizations for Claude.
It Might Due to Load Balancing and Resource Management
As Claude’s popularity has grown, Anthropic may be struggling to keep up with demand. To manage this, they could be selectively routing some queries to smaller, less capable models or limiting the computational resources allocated to each query. This could explain why performance seems worse during peak usage times.
It Might Due to Ongoing Training and Updates
It’s possible that Anthropic is continuously fine-tuning or updating Claude based on user interactions and feedback. While the intent would be to improve the model, this process could inadvertently introduce regressions or unintended behaviors.
It Might Due to Safety Filters and Constraints
Anthropic may have added or tightened content filters and safety constraints on Claude. While intended to prevent harmful outputs, overzealous restrictions can hamper the model’s ability to engage with certain topics or tasks effectively.
A Closer Look: Before and After Comparisons
To illustrate the potential decline in Claude’s capabilities, let’s examine some before and after examples:Code Generation (Before):
def fibonacci(n):
if n <= 1:
return n
else:
return fibonacci(n-1) + fibonacci(n-2)
# Generate first 10 Fibonacci numbers
fib_sequence = [fibonacci(i) for i in range(10)]
print(fib_sequence)Code Generation (After):
def fibonacci(n):
# TODO: Implement fibonacci sequence
pass
# Generate first 10 Fibonacci numbers
fib_sequence = []
for i in range(10):
# TODO: Append fibonacci numbers
pass
print(fib_sequence)In the “before” example, Claude produces a correct and concise implementation of the Fibonacci sequence. The “after” example shows a degraded response with placeholder comments and incomplete logic.
Complex Reasoning (Before):
”The relationship between inflation and unemployment is complex and often described by the Phillips curve. In the short run, there tends to be an inverse relationship — lower unemployment is associated with higher inflation and vice versa. This occurs because as the labor market tightens, workers can demand higher wages, which can lead to increased prices. However, in the long run, the relationship breaks down as expectations adjust and other factors come into play. Policymakers often face a trade-off between these two economic indicators when making decisions.”
Complex Reasoning (After):
”Inflation and unemployment are related. When unemployment is low, inflation can go up. When unemployment is high, inflation can go down. This is called the Phillips curve. It’s important for the economy.”
The “before” response demonstrates a nuanced understanding of the topic with specific details and explanations. The “after” response is overly simplistic and lacks depth.
What Can Users Do?
If you’re experiencing issues with Claude, there are a few strategies you can try:
- Use the API version: Some users report better performance using Claude via API rather than the web interface.
One of the easiest way to use Claude via API, actually, virtually ANY AI MODEL via API, is using Anakin AI.
Anakin AI is the all-in-one AI Platform that allows you to manage all AI models easily in one place with a handy API support as well. No need to manage multiple AI Subscriptions and keep switching all the time, Anakin AI can handel them all!
Oh, you can also use the awesome uncensored LLM at Anakin AI as well, access the power of AI without any restrcitions!
2. Break tasks into smaller chunks: Instead of asking Claude to handle large, complex tasks all at once, try breaking them down into smaller, more focused queries.
3. Provide clear context: Be explicit about what you’re asking and provide relevant background information to help guide Claude’s responses.
4. Experiment with prompting techniques: Try different ways of phrasing your queries or use techniques like chain-of-thought prompting to improve results.
5. Consider alternatives: If Claude isn’t meeting your needs, you may want to explore other AI assistants or language models such as Llama 3.1 405B.
Conclusion
While it’s difficult to definitively prove that Claude 3.5 Sonnet is “getting dumber,” the consistent reports from users suggest that something has changed. Whether due to technical optimizations, resource constraints, or other factors, it appears that Claude’s performance may have declined in certain areas.
As AI technology rapidly evolves, it’s likely that we’ll continue to see fluctuations in model performance as companies experiment with different approaches. Users should remain adaptable and be prepared to adjust their workflows as needed.
Ultimately, Anthropic will need to address these concerns if they want to maintain user trust and satisfaction. Greater transparency about any changes or optimizations made to Claude would go a long way in helping users understand and adapt to the model’s evolving capabilities.
