Introduction

The era when Moore's Law could be relied upon to double computing power every 18 months is over. Fable's arrival in the market marked the end of this golden age of the "free lunch" for developers. But what does this really mean for tech companies today?

Historical Context

Herb Sutter famously described this period as the "free lunch" in a seminal essay. For decades, developers could afford not to rigorously optimize their code, knowing that future hardware improvements would offset their inefficiencies. However, with the slowdown of Moore's Law starting in the mid-2000s, developers had to rethink their approach.

The Impact of Fable

Fable revolutionized the market with its impressive capabilities, albeit at a significant cost. Compared to other models like GLM and Opus, Fable stands out in performance but requires an investment not all companies are willing to make. GLM 5.2, for instance, offers a viable alternative at a much lower cost.

Optimization and Strategies

With the end of the "free lunch," companies must now focus on optimizing their resources. This involves carefully choosing which models to use for which tasks. While less powerful than Fable, GLM is sufficient for many repetitive tasks when used with appropriate context.

The Future of Inference

Despite falling inference costs, companies must still weigh the pros and cons before sending complex tasks to expensive models like Fable. Smaller models, such as K3 and Qwen, also benefit from harness innovations, making them increasingly competitive.

Security and Access Considerations

Fable introduced strict access controls and data retention requirements that force companies to think about where they send their data. This has prompted many organizations to consider more secure alternatives.

Conclusion

The end of Moore's Law and the emergence of Fable are redefining the tech development landscape. Companies need to be strategic in their choice of AI models to maximize efficiency while minimizing costs. Ready to discuss the best strategy for your company? Let's discuss your project in 15 minutes.
