Analysis Summary

OpenAI's GPT-3.5 Turbo was a widely adopted model in 2023, but it now sits well below the capability floor of current-generation alternatives. The intelligence index is low, coding performance is limited, and the 16K context window is modest by today's standards. Tool use and function calling are supported, which gives it some structured task capability, but instruction-following and reasoning quality lag significantly behind modern models.

For businesses, GPT-3.5 Turbo is primarily relevant for legacy integrations. At $0.50/1M input and $1.50/1M output, pricing is reasonable, but models like Qwen3.5-Flash or LiquidAI's smaller models offer comparable or better performance at similar or lower cost. There is little reason to start new projects on this model.

Teams with existing GPT-3.5 Turbo deployments should evaluate migration to a current-generation model. The capability gap has widened significantly since 2023, and the cost savings from staying on this model are unlikely to outweigh the quality improvements available elsewhere.

Editorial notes

GPT-3.5 Turbo is a legacy OpenAI model with limited reasoning and a 16K context window; tool use and function calling are supported, but it is outperformed by many cheaper current-generation models.

Rankings consider pricing, capabilities, benchmarks, and real-world applicability and are refreshed as new models launch. Feedback?
