Model Details
GPT-3.5 Turbo
Quick answer: GPT-3.5 Turbo is OpenAI's original low-cost ChatGPT API model, released March 2023. It is a legacy baseline in agentic and web-navigation research — early benchmarks like Mind2Web reported it struggling on multi-step, tool-use tasks compared to GPT-4.
At a Glance
Historical significance
- Powered the initial public ChatGPT API launch and countless early LLM-agent research baselines
- Cheap, fast alternative to GPT-4 for high-volume chat workloads in 2023
Modern context
- Long since superseded by GPT-4o mini, GPT-4.1 mini, and other efficient-tier models
- Used mainly today as a historical reference point in agent-benchmark papers (e.g. Mind2Web) rather than a production choice
