In a recent article from InfoWorld, the benefits and pitfalls of large language models (LLMs) such as GPT-4 in relation to coding tasks are brought into the spotlight. This detailed discourse is vital given the rapid rise and increasing usage of these models, and it invites further exploration of whether these systems are indeed the future of artificial intelligence (AI), particularly in relation to software development.

Are Large Language Models Suitable for Coding?

Key Takeaways:

  • Large Language Models (LLMs), like GPT-4, while adept at generating fluent and confident text, may not be as efficient or accurate for tasks requiring high precision, such as coding or game playing.
  • Reinforcement learning models, which iteratively strive for the best result, are suggested as a more effective alternative to LLMs for certain tasks, notably including software development and game playing.
  • Despite improvements in generative AI tools for coding, such as GitHub Copilot, they still require human supervision for accuracy, indicating that while LLMs have potential in certain domains, their effectiveness in areas requiring higher accuracy and precision might be limited.

The Pitfalls of LLMs in Non-Language Tasks: Expert Opinions

While these models have shown remarkable ability to generate highly fluent and confident text, their application might not be as effective or accurate in tasks that require a high level of precision and accuracy, such as writing code. Their abilities are challenged when applied to games like chess and go, performing mathematical operations, or in the precise world of software development due to their innate tendency to generate text, even if incorrect, with high confidence – a phenomenon termed as ‘hallucination’.

There is, however, no suggestion that LLMs are merely hype. Instead, it points towards a need for a more balanced understanding and less exaggeration in the discourse surrounding generative artificial intelligence (GenAI). The article points out that experts differ in their opinions on how to mitigate these ‘hallucinations’. Some suggest that adding reinforcement learning with human feedback could resolve the issue, while others argue that the problem lies deeper in the models’ lack of non-linguistic knowledge.

Reinforcement Learning Models: A Viable Alternative?

The CEO of Diffblue, Mathew Lodge, argues for the superiority of reinforcement learning models over LLMs in certain areas. He claims these models are faster, cheaper to run, and more efficient at tasks ranging from gaming to coding. The article suggests that the generative AI may be misdirected, forcing it into domains where reinforcement learning is much more potent.

For instance, Google’s AlphaGo, the leading AI for the game of Go, relies heavily on reinforcement learning. It uses a process of probabilistic search – generating different solutions to a problem, testing them, using the results to improve the next suggestion, and then repeating that process thousands of times to find the best result.

The Advantages & Lingering Problems with LLMs &

The persistent belief in LLMs’ potential improvement, however, doesn’t align with the evidence of their current struggles. For example, despite GPT-4 performing better than GPT-3 at certain tasks, it continues to struggle with mathematical operations. Also, the core characteristic of LLMs – generating likely outputs based on observed patterns – may not necessarily result in the correct or best answer, particularly in fields like mathematics or physics.

On the other hand, reinforcement learning AI excels in producing accurate results because it iterates towards the desired goal. While LLMs provide ‘good enough’ one-shot or few-shot answers, reinforcement learning strives for the best possible result.

Applying Reinforcement Learning to Software Development

Finally, when it comes to software development, the potential of GenAI has been demonstrated by developers who have improved productivity using tools like GitHub Copilot or Amazon CodeWhisperer. However, while these tools predict what code might come next, they still require human supervision for compiling and running the code correctly. Lodge argues that reinforcement learning can accomplish large-scale autonomous coding more accurately.


In conclusion, while LLMs offer potential in certain domains, they might not be the best fit for tasks that require a higher level of accuracy and consistency. Reinforcement learning, on the other hand, seems to hold promise in fields requiring precision and scale, such as software development.

Unraveling the Truth: 10 Common Misconceptions about Large Language Models

Despite the increasing prominence of Large Language Models (LLMs) in artificial intelligence discourse, several misconceptions continue to circulate. These misunderstandings often arise due to overhype, lack of understanding, or a general misinterpretation of their capabilities and limitations.

  • Infallibility: Although they are powerful tools, LLMs are not perfect and can often generate errors or inaccurate outputs.
  • Independent writing of flawless code: While they have shown promise in assisting with coding tasks, they still require significant human oversight to ensure accuracy.
  • All LLMs are alike: Different models have unique strengths, weaknesses, and features, depending on their architecture and training data.
  • The human understanding of context: While they are proficient at recognizing patterns and generating text, they don’t truly understand context or have human-like comprehension.
  • Size equals superiority: A larger model doesn’t necessarily mean a better one. Even though GPT-4 outperforms GPT-3 at certain tasks, it still struggles with tasks that were challenging for GPT-3.
  • Solution to any Problem: Despite their versatility, there are still tasks where other models, especially reinforcement learning models, perform better.
  • LLMs generate the correct answer every time: Due to their probabilistic nature, they often produce likely outputs but not necessarily the only correct answer.
  • Replacing human workers: LLMs are tools designed to assist human workers, not replace them. Human guidance is necessary to review and refine their output.
  • Training an LLM is easy: Training LLMs is computationally expensive and requires significant time and resources.
  • LLMs learn and evolve on their own: LLMs don’t learn from their mistakes unless they are explicitly retrained with new data that includes feedback on their errors.

Understanding these misconceptions helps to cultivate a balanced and informed view of LLMs, promoting their effective and appropriate usage in various applications.
