Introducing ChatGPT's AI Models: GPT 3.5 Turbo and GPT 4

ChatGPT offers two main AI models to choose from - GPT 3.5 Turbo and GPT 4. GPT stands for Generative Pre-trained Transformer. GPT 3.5 Turbo is a fine-tuned version of the GPT-3 model, optimized for speed on everyday tasks. GPT 4 is an entirely new model focused on more advanced reasoning, creativity, and capabilities.

Access to GPT 4 currently requires a paid ChatGPT Plus subscription. The free tier only allows GPT 3.5 Turbo. We'll analyze whether the extra features are worth the monthly price later on.

GPT 3.5 Turbo: Fastest Model for Everyday Tasks

According to ChatGPT's interface, GPT 3.5 Turbo is their fastest AI model designed for most everyday queries. It handles straightforward questions, basic research, and simple writing tasks efficiently. The compromise is that it occasionally struggles with complex logic or reasoning compared to GPT 4.

GPT 4: More Advanced Reasoning and Capabilities

In contrast, GPT 4 is marketed as ChatGPT's most capable AI system specialized for advanced reasoning. Its responses tend to seem more creative, nuanced, and human. GPT 4 also enables exclusive features like interpreting code, integrating web browsing, and accepting multimodal inputs. On standardized tests like the bar exam, GPT 4 scored in the 90th percentile while GPT 3.5 Turbo only managed the 10th percentile. This demonstrates GPT 4's superior logical reasoning abilities, albeit in a closed testing environment.

Comparing GPT 3.5 Turbo and GPT 4 Performance

When using ChatGPT in practice, GPT 4 generally provides more accurate, factual responses compared to GPT 3.5 Turbo. It is also more restricted in terms of generating inappropriate content. However, these advantages come at the cost of slower response times than the blazing fast GPT 3.5 Turbo model.

Standardized Testing: GPT 4 Excels

As evidenced by the bar exam example, GPT 4 dominates GPT 3.5 Turbo on complex standardized tests designed to evaluate logical reasoning abilities. While impressive, these closed testing scenarios may not translate directly to real-world use cases.

Factual Responses: GPT 4 More Accurate

In practice, GPT 4 supplies more truthful, factual answers compared to GPT 3.5 Turbo which occasionally 'hallucinates' information. This is likely because GPT 4 was trained on larger datasets allowing more factual knowledge absorption.

Inappropriate Content: GPT 4 More Restricted

GPT 4 is also less prone to generating hateful, biased or adult content. Its internal content filters appear superior at restricting inappropriate subject matter. This minimizes harmful responses, albeit slightly limiting its capabilities in certain edge cases.

GPT 4 Exclusive Features on ChatGPT

The advanced GPT 4 model enables several unique features not accessible by GPT 3.5 Turbo users on the free tier. These value-added capabilities include interpreting code, integrating web browsing, accepting multimodal inputs, and custom plugin extensions.

Code Interpreter for Programming

One of GPT 4's most exciting capabilities is intelligently interpreting and interacting with code. Users can upload code files or snippets and GPT 4 will analyze, document, debug, rewrite and even run the code. This unlocks advanced programming assistance.

Web Browsing Integration

At launch, GPT 4 briefly allowed directly embedding links and integrating web browsing into conversations before being restricted over content concerns. If re-enabled, this would greatly strengthen ChatGPT's knowledge by pulling contextual information from websites.

Multimodal Inputs Like Images

GPT 4 supports accepting multimodal inputs including images, videos and files to enhance responses. While mostly unseen, this functionality will likely expand over time to improve ChatGPT's understanding and capabilities.

Plugin Extensions

Finally, GPT 4 introduces a plugins architecture for custom enhancements. Developers can build extensions adding new buttons, features and contextual responses. This presents a framework to expand ChatGPT's skills over time.

Is GPT 4 Worth the Subscription Cost?

Given its exclusive capabilities, GPT 4 seems very promising for power users. However, the free GPT 3.5 Turbo still performs admirably for more basic use cases. Let's break down ChatGPT's paid subscription to help assess if the $20 monthly investment is worthwhile.

Monthly Price for ChatGPT Plus Access

A ChatGPT Plus subscription currently runs $20 per month in the United States, granting early access to new AI models and features. This includes unlocking GPT 4 and associated capabilities like the code interpreter.

Free Tier Still Functional for Most Uses

Fortunately, the free tier utilizing GPT 3.5 Turbo remains highly capable for straightforward queries, research, writing assistance and more. You can utilize ChatGPT quite effectively without paying unless advanced features become essential.

Evaluate if Advanced Features Are Necessary

Ultimately, the Plus subscription value depends on your personal or professional needs. If you require stronger logical reasoning, multimodal inputs, expert programming assistance, web integration and maximum accuracy, GPT 4 may prove indispensible despite the monthly cost.

FAQ
