GPT-4 1106 Preview—A review of performance and quality # GPT-4 1106 Preview The November 2023 GPT-4 Turbo preview featuring a 128k context window, JSON mode, and improved instruction-following for complex generation tasks. [Start building](https://telnyx.com/sign-up)[GET Available Models](https://developers.telnyx.com/docs/inference/models) ## about Announced at OpenAI DevDay in November 2023, this preview expanded [GPT-4's context window from 8K to 128K tokens](https://developers.openai.com/docs/models/gpt-4-turbo) while cutting input pricing by 3x. It introduced JSON mode, parallel function calling, and reproducible outputs via a seed parameter, though it was widely noted for a "laziness" problem where the model would truncate code or respond with "rest remains the same."

GPT-4 Turbo 1106 Preview was the first release of GPT-4 Turbo in November 2023, introducing the 128K context window and JSON mode. The [0125 snapshot](https://telnyx.com/llm-library/gpt-4-0125-preview) later fixed issues with format-following and added improved code generation. ### Is GPT-4 discontinued? OpenAI is deprecating individual GPT-4 snapshots as newer models supersede them. The [1106 preview](https://telnyx.com/llm-library/gpt-4-1106-preview) remains available but OpenAI recommends migrating to GPT-4o or GPT-4.1 for new projects. ### What is the difference between GPT-4 and o1 Preview? GPT-4 is a general-purpose language model, while o1 Preview is a reasoning-focused model that uses internal chain-of-thought before responding. The excels at broad tasks, while o1 is better for math, science, and complex analytical problems. 128000 ## Use cases for GPT-4 1106 Preview 1. **Book-length document analysis:** The 128K context window processes full manuscripts, regulatory filings, or codebases in a single prompt for comprehensive analysis without chunking. 2. **Guaranteed JSON extraction:** JSON mode ensures structurally valid output for data pipelines, eliminating the parsing failures that plagued earlier GPT-4 versions. 3. **Reproducible content generation:** The seed parameter delivers deterministic outputs for applications requiring audit trails, regression testing, or consistent baseline comparisons. ## Quality Arena Elo1251 MMLUN/A MT Bench9.32 GPT-4 1106 preview maintains the 86.5% MMLU (5-shot) baseline of the GPT-4 Turbo family while adding a 128K context window, JSON mode, and parallel function calling. Its Arena ELO of 1,251 places it above GPT-4 (1,165) but below GPT-4o (1,316) on the same sheet, reflecting incremental improvements in chat quality beyond what MMLU captures. **GPT-4 Omni** 1316 **Claude-3-7-Sonnet-Latest** 1268 **GPT-4 1106 Preview** 1251 **Llama-4-Scout-Instruct** 1250 **Llama 3.1 70B Instruct** 1248 ## pricing The cost per 1,000 tokens for running the model with Telnyx Inference is $0.0010\. For instance, analyzing 1,000,000 customer chats, assuming each chat is 1,000 tokens long, would cost $1,000. ## What's Twitter saying? * **Mixed coding performance**: [While GPT-4 Turbo showed faster inference,](https://telnyx.com/llm-library/gpt-4-1106-preview) coding benchmarks revealed trade-offs—GPT-4 solved 86 out of 122 tasks on the first attempt compared to GPT-4 Turbo's 56, though GPT-4 Turbo improved significantly on second attempts with 28 successes versus GPT-4's 10. * **Quality concerns despite claims**: [Some developers reported that GPT-4-1106-preview generated](https://blog.galaxy.ai/compare/gpt-4-1106-preview-vs-gpt-4-turbo-preview) consistently worse content than the previous GPT-3.5-turbo model, questioning whether this was due to the model's "not yet suited for production traffic" status or other factors. * **Latency and responsiveness issues**: [Users on social media reported significant](https://the-decoder.com/openai-gpt-4-turbo-early-benchmarks-show-mixed-performance/) latency problems with GPT-4-Turbo (1106-Preview), noting it was slower than the original GPT-4, and some observed that Azure deployments returned noticeably shorter and less detailed responses compared to OpenAI's direct API. | Organization | Model Name | Tasks | Languages Supported | Context Length

This is roughly [one-third the cost of the original GPT-4](https://telnyx.com/llm-library/gpt-4-0125-preview) while offering a larger context window and additional features. ### What did GPT-4 1106 Preview introduce? The 1106 snapshot introduced the 128K context window, JSON mode for structured outputs, parallel function calling, and improved instruction following. These features made it the [foundation for GPT-4 Turbo](https://telnyx.com/llm-library/gpt-4-1106-preview) and influenced subsequent model releases. ### Is GPT-4 1106 Preview still worth using? GPT-4 1106 Preview is functional but has been superseded by the [0125 snapshot](https://telnyx.com/llm-library/gpt-4-0125-preview), GPT-4o, and GPT-4.1\. Unless you have a specific reason to pin to this version, migrating to a newer model will give you better results at equal or lower cost.
