GPT-3.5 Turbo 1106

GPT-3.5 Turbo-1106 represents a November 2023 consolidation of OpenAI's earlier workhorse model variants, merging the standard and 16K versions into a single architecture defaulting to a 16,384-token context window. This snapshot introduced structured output capabilities through JSON mode, enabling developers to extract database-ready records from unstructured text without post-processing, while parallel function calling allows the model to query multiple external services simultaneously within a single conversation turn. A seed parameter delivers reproducible outputs, making it useful for automated testing pipelines that require consistent baseline responses.

On general knowledge benchmarks, the model scores 70.0% on MMLU and 7.94 on MT-Bench with an Arena Elo of 1068, placing it ahead of comparable instruction-tuned models while remaining below frontier systems. Input pricing dropped 50% from the prior snapshot, and training data advanced to a April 2023 cutoff, offering a practical balance of cost efficiency and capability for structured data extraction, multi-tool API orchestration, and deterministic test generation at production scale.
