OpenAI claims that GPT-4 was improved with lessons from their adversarial testing program as well as ChatGPT, leading to better results on factuality, steerability, and better alignment.
## GPT-4 Turbo
GPT-4 Turbo is the latest GPT-4 model. The model has improved instruction following, JSON mode, reproducible outputs, parallel function calling, and more.
The model has a context window of 128K, which can fit over 300 pages of text in a single prompt. GPT-4 Turbo is currently only available via API for paying developers to try by passing `gpt-4-1106-preview` in the API.
At the time of release the training data cutoff point for the model is April 2023.
## Vision Capabilities
GPT-4 APIs currently only supports text inputs but there is plan for image input capability in the future. OpenAI claims that in comparison with GPT-3.5 (which powers ChatGPT), GPT-4 can be more reliable, creative, and handle more nuanced instructions for more complex tasks. GPT-4 improves performance across languages.

This is an impressive result as the model follows the correct instruction even when there is other available information on the image. This open a range of capabilities to explore charts and other visual inputs and being more selective with the analyses.

## GPT-4 Turbo With Vision
GPT-4 Turbo with vision is the newest version of GPT-4. It has the ability to understand images, in addition to all other GPT-4 Turbo capabilties. The model returns a maximum of 4,096 output tokens, and a context window of 128,000 tokens. This is a preview model version and not suited yet for production traffic.

## Text Generation Capabilities
Using GPT-4's text generation, you can build applications to:
- Draft documents
- Write code
- Answer questions about a knowledge base
- Analyze texts
- Give software a natural language interface
- Tutor in a range of subjects
- Translate languages
- Simulate characters for games
**Chat Completions**
The Chat Completions API from OpenAI allows for both multi-turn and single-turn interactions through a format that is conducive to conversation. This API operates by taking a list of messages, comprising 'system', 'user', or 'assistant' roles with associated content, and returns a contextually appropriate response from the model.
An example of an API call demonstrates how messages are formatted and fed to the model, which is capable of maintaining a coherent dialogue by referencing previous messages within the conversation. The conversation can begin with a system message that sets the tone and guidelines for the interaction, though it's optional. Every input must contain all the relevant context, as the model does not retain memory from previous requests and relies on the provided history to generate responses.
```
from openai import OpenAI
client = OpenAI()
response = client.chat.completions.create(
model="gpt-4-1106-preview",
messages=[
{"role": "system", "content": "You are a helpful assistant."},
{"role": "user", "content": "Who won the world series in 2020?"},
{"role": "assistant", "content": "The Los Angeles Dodgers won the World Series in 2020."},
{"role": "user", "content": "Where was it played?"}
]
)
```
**JSON mode**
A common way to use Chat Completions is to instruct the model to always return JSON in some format that makes sense for your use case, by providing a system message. This works well, but occasionally the models may generate output that does not parse to valid JSON.
To prevent these errors and improve model performance, when calling gpt-4-1106-preview the user can set `response_format` to `{ type: "json_object" }` to enable JSON mode. When JSON mode is enabled, the model is constrained to only generate strings that parse into valid JSON. The string "JSON" must appear in the system message for this functionality to work.
**Reproducible Outputs**
Chat Completions are non-deterministic by default. However, OpenAI now offers some control towards deterministic outputs by giving the user access to the seed parameter and the system_fingerprint response field.
To receive (mostly) deterministic outputs across API calls, users can:
- Set the seed parameter to any integer and use the same value across requests one would like deterministic outputs for.
- Ensure all other parameters (like prompt or temperature) are the exact same across requests.
Sometimes, determinism may be impacted due to necessary changes OpenAI makes to model configurations on their end. To help keep track of these changes, they expose the system_fingerprint field. If this value is different, you may see different outputs due to changes that have been made on OpenAI's systems.
More info about this in the [OpenAI Cookbook](https://cookbook.openai.com/examples/deterministic_outputs_with_the_seed_parameter).
## Function Calling
In API calls, users can describe functions and have the model intelligently choose to output a JSON object containing arguments to call one or many functions. The Chat Completions API does not call the function; instead, the model generates JSON that you can use to call the function in your code.
The latest models (`gpt-3.5-turbo-1006` and `gpt-4-1106-preview`) have been trained to both detect when a function should to be called (depending on the input) and to respond with JSON that adheres to the function signature more closely than previous models. With this capability also comes potential risks. OpenAI strongly recommends building in user confirmation flows before taking actions that impact the world on behalf of users (sending an email, posting something online, making a purchase, etc).
Function calls can also be made in parallel. It is helpful for cases where the user wants to call multiple functions in one turn. For example, users may want to call functions to get the weather in 3 different locations at the same time. In this case, the model will call multiple functions in a single response.
**Common Use Cases**
Function calling allows you to more reliably get structured data back from the model. For example, you can:
- Create assistants that answer questions by calling external APIs (e.g. like ChatGPT Plugins)
- e.g. define functions like `send_email(to: string, body: string)`, or `get_current_weather(location: string, unit: 'celsius' | 'fahrenheit')`
- Convert natural language into API calls
- e.g. convert "Who are my top customers?" to `get_customers(min_revenue: int, created_before: string, limit: int)` and call your internal API
- Extract structured data from text
- e.g. define a function called `extract_data(name: string, birthday: string)`, or `sql_query(query: string)`
The basic sequence of steps for function calling is as follows:
- Call the model with the user query and a set of functions defined in the functions parameter.
- The model can choose to call one or more functions; if so, the content will be a stringified JSON object adhering to your custom schema (note: the model may hallucinate parameters).
- Parse the string into JSON in your code, and call your function with the provided arguments if they exist.
- Call the model again by appending the function response as a new message, and let the model summarize the results back to the user.
