The Breakdown
GPT-4 Turbo was the industry standard for nearly a year, defining what 'smart' AI looked like. It introduced the 128k context window to the masses and powered the explosion of the AI agent ecosystem. While it has been superseded by the faster and cheaper GPT-4o, Turbo remains a crucial benchmark in AI history. It is the baseline against which all other models are measured. Developers still maintain it for legacy applications where prompt stability is prioritized over speed.

The Good
- The reliable workhorse that defined the generation
- Massive ecosystem support and tooling
- Still highly capable for complex reasoning
The Bad
- Significantly more expensive than GPT-4o or DeepSeek
- Slower inference speed
- Knowledge cutoff is getting stale
The Verdict
The former king, now retired to the hall of fame. While still powerful, there is almost no reason to use it over GPT-4o today unless you have a legacy prompt that breaks on newer models.
