+# Yeager.ai
+
+This page covers how to use [Yeager.ai](https://yeager.ai) to generate LangChain tools and agents.
+
+## What is Yeager.ai?
+Yeager.ai is an ecosystem designed to simplify the process of creating AI agents and tools. 
+
+It features yAgents, a No-code LangChain Agent Builder, which enables users to build, test, and deploy AI solutions with ease. Leveraging the LangChain framework, yAgents allows seamless integration with various language models and resources, making it suitable for developers, researchers, and AI enthusiasts across diverse applications.
+
+## yAgents
+Low code generative agent designed to help you build, prototype, and deploy Langchain tools with ease. 
+
+### How to use?
+```
+pip install yeagerai-agent
+yeagerai-agent
+```
+Go to http://127.0.0.1:7860
+
+This will install the necessary dependencies and set up yAgents on your system. After the first run, yAgents will create a .env file where you can input your OpenAI API key. You can do the same directly from the Gradio interface under the tab "Settings".
+
+`OPENAI_API_KEY=<your_openai_api_key_here>`
+
+We recommend using GPT-4,. However, the tool can also work with GPT-3 if the problem is broken down sufficiently.
+
+### Creating and Executing Tools with yAgents
+yAgents makes it easy to create and execute AI-powered tools. Here's a brief overview of the process:
+1. Create a tool: To create a tool, provide a natural language prompt to yAgents. The prompt should clearly describe the tool's purpose and functionality. For example:
+`create a tool that returns the n-th prime number`
+
+2. Load the tool into the toolkit: To load a tool into yAgents, simply provide a command to yAgents that says so. For example:
+`load the tool that you just created it into your toolkit`
+
+3. Execute the tool: To run a tool or agent, simply provide a command to yAgents that includes the name of the tool and any required parameters. For example:
+`generate the 50th prime number`
+
+You can see a video of how it works [here](https://www.youtube.com/watch?v=KA5hCM3RaWE).
+
+As you become more familiar with yAgents, you can create more advanced tools and agents to automate your work and enhance your productivity.
+
+For more information, see [yAgents' Github](https://github.com/yeagerai/yeagerai-agent) or our [docs](https://yeagerai.gitbook.io/docs/general/welcome-to-yeager.ai)

I also heard that at first it was seized by U.S. customs if it ever tried to enter this country, therefore being a fan of films considered \"controversial\" I really had to see this for myself.<br /><br />The plot is centered around a young Swedish drama student named Lena who wants to learn everything she can about life. In particular she wants to focus her attentions to making some sort of documentary on what the average Swede thought about certain political issues such as the Vietnam War and race issues in the United States. In between asking politicians and ordinary denizens of Stockholm about their opinions on politics, she has sex with her drama teacher, classmates, and married men.<br /><br />What kills me about I AM CURIOUS-YELLOW is that 40 years ago, this was considered pornographic. Really, the sex and nudity scenes are few and far between, even then it\\'s not shot like some cheaply made porno. While my countrymen mind find it shocking, in reality sex and nudity are a major staple in Swedish cinema. Even Ingmar Bergman, arguably their answer to good old boy John Ford, had sex scenes in his films.<br /><br />I do commend the filmmakers for the fact that any sex shown in the film is shown for artistic purposes rather than just to shock people and make money to be shown in pornographic theaters in America.

I\\'ve seen R-rated films with male nudity. Granted, they only offer some fleeting views, but where are the R-rated films with gaping vulvas and flapping labia? Nowhere, because they don\\'t exist. The same goes for those crappy cable shows: schlongs swinging in the breeze but not a clitoris in sight.

To think about a legend like Lucille Ball being portrayed the way she was in the movie is horrendous. I cannot believe out of all the actresses in the world who could play a much better Lucy, the producers decided to get Rachel York. She might be a good actress in other roles but to play the role of Lucille Ball is tough. It is pretty hard to find someone who could resemble Lucille Ball, but they could at least find someone a bit similar in looks and talent. If you noticed York\\'s portrayal of Lucy in episodes of I Love Lucy like the chocolate factory or vitavetavegamin, nothing is similar in any way-her expression, voice, or movement.<br /><br />To top it all off, Danny Pino playing Desi Arnaz is horrible.

Ben Gazzara sports his usual cat\\'s-got-canary grin in a futile attempt to elevate the meager plot, which requires him to pursue Audrey Hepburn with all the interest of a narcoleptic at an insomnia clinic.

It\\'s a movie and we can expect that much, if that\\'s what you\\'re looking for you\\'d be better off picking up a copy of Vogue.<br /><br />Oh- and it has to be mentioned that Colleen Camp thoroughly annoys, even apart from her singing, which, while competent, is wholly unconvincing... the country and western numbers are woefully mismatched with the standards on the soundtrack. Surely this is NOT what Gershwin (who wrote the song from which the movie\\'s title is derived) had in mind; his stage musicals of the 20\\'s may have been slight, but at least they were long on charm. \"They All Laughed\" tries to coast on its good intentions, but nobody- least of all Peter Bogdanovich - has the good sense to put on the brakes.<br /><br />Due in no small part to the tragic death of Dorothy Stratten, this movie has a special place in the heart of Mr. Bogdanovich- he even bought it back from its producers, then distributed it on his own and went bankrupt when it didn\\'t prove popular. His rise and fall is among the more sympathetic and tragic of Hollywood stories, so there\\'s no joy in criticizing the film... there _is_ real emotional investment in Ms. Stratten\\'s scenes.

This entire movie was written by Peter, and it shows how out of touch with real people he was. You're supposed to write what you know, and he did that, indeed. And leaves the audience bored and confused, and jealous, for that matter. This is a curio for people who want to see Dorothy Stratten, who was murdered right after filming.

Ben Gazarra as an attractive and very seductive man, with the women falling for him as if her were a Brad Pitt, Antonio Banderas or George Clooney, is quite ridiculous. In the end, the greater attractions certainly are the presence of the Playboy centerfold and playmate of the year Dorothy Stratten, murdered by her husband pretty after the release of this movie, and whose life was showed in \"Star 80\" and \"Death of a Centerfold: The Dorothy Stratten Story\"; the amazing beauty of the sexy Patti Hansen, the future Mrs. Keith Richards; the always wonderful, even being fifty-two years old, Audrey Hepburn; and the song \"Amigo\", from Roberto Carlos. Although I do not like him, Roberto Carlos has been the most popular Brazilian singer since the end of the 60\\'s and is called by his fans as \"The King\". I will keep this movie in my collection only because of these attractions (manly Dorothy Stratten). My vote is four.<br /><br />Title (Brazil): \"Muito Riso e Muita Alegria\" (\"Many Laughs and Lots of Happiness\")', metadata={'label': 0})]"

 ```
 
+If you do not wish to specify `input_variables` manually, you can also create a `PromptTemplate` using `from_template` class method. `langchain` will automatically infer the `input_variables` based on the `template` passed.
+
+```python
+template = "Tell me a {adjective} joke about {content}."
+
+prompt_template = PromptTemplate.from_template(template)
+prompt_template.input_variables
+# -> ['adjective', 'content']
+prompt_template.format(adjective="funny", content="chickens")
+# -> Tell me a funny joke about chickens.
+```
 
 You can create custom prompt templates that format the prompt in any way you want. For more information, see [Custom Prompt Templates](examples/custom_prompt_template.ipynb).
 
 
 <!-- TODO(shreya): Add link to Jinja -->
 
-:::{note}
-Currently, the template should be formatted as a Python f-string. We also support Jinja2 templates (see [Using Jinja templates](examples/custom_prompt_template.ipynb)). In the future, we will support more templating languages such as Mako.
-:::
-
-
-## Load a prompt template from LangChainHub
-
-LangChainHub contains a collection of prompts which can be loaded directly via LangChain.
+## Template formats
 
+By default, `PromptTemplate` will treat the provided template as a Python f-string. You can specify other template format through `template_format` argument:
 
 ```python
+# Make sure jinja2 is installed before running this
+
+jinja2_template = "Tell me a {{ adjective }} joke about {{ content }}"
+prompt_template = PromptTemplate.from_template(template=jinja2_template, template_format="jinja2")
+
+prompt_template.format(adjective="funny", content="chickens")
+# -> Tell me a funny joke about chickens.
+```
+
+Currently, `PromptTemplate` only supports `jinja2` and `f-string` templating format. If there is any other templating format that you would like to use, feel free to open an issue in the [Github](https://github.com/hwchase17/langchain/issues) page. 
+
+## Validate template
+
+By default, `PromptTemplate` will validate the `template` string by checking whether the `input_variables` match the variables defined in `template`. You can disable this behavior by setting `validate_template` to `False`
+
+```python
+template = "I am learning langchain because {reason}."
+
+prompt_template = PromptTemplate(template=template, 
+                                 input_variables=["reason", "foo"]) # ValueError due to extra variables
+prompt_template = PromptTemplate(template=template, 
+                                 input_variables=["reason", "foo"], 
+                                 validate_template=False) # No error
+```
+
+
+## Serialize prompt template
+
+You can save your `PromptTemplate` into a file in your local filesystem. `langchain` will automatically infer the file format through the file extension name. Currently, `langchain` supports saving template to YAML and JSON file. 
+
+```python
+prompt_template.save("awesome_prompt.json") # Save to JSON file
+```
+
+```python
+from langchain.prompts import load_prompt
+loaded_prompt = load_prompt("awesome_prompt.json")
+
+assert prompt_template == loaded_prompt
+```
+
+`langchain` also supports loading prompt template from LangChainHub, which contains a collection of useful prompts you can use in your project. You can read more about LangChainHub and the prompts available with it [here](https://github.com/hwchase17/langchain-hub).
+
+```python
+
 from langchain.prompts import load_prompt
 
 prompt = load_prompt("lc://prompts/conversation/prompt.json")
 prompt.format(history="", input="What is 1 + 1?")
 ```

+- [Multi-Player D&D](agent_simulations/multi_player_dnd.ipynb): an example of how to use a generic dialogue simulator for multiple dialogue agents with a custom speaker-ordering, illustrated with a variant of the popular Dungeons & Dragons role playing game.
+- [Decentralized Speaker Selection](agent_simulations/multiagent_bidding.ipynb): an example of how to implement a multi-agent dialogue without a fixed schedule for who speaks when. Instead the agents decide for themselves who speaks by outputting bids to speak. This example shows how to do this in the context of a fictitious presidential debate.
+- [Authoritarian Speaker Selection](agent_simulations/multiagent_authoritarian.ipynb): an example of how to implement a multi-agent dialogue, where a privileged agent directs who speaks what. This example also showcases how to enable the privileged agent to determine when the conversation terminates. This example shows how to do this in the context of a fictitious news show.
 - [Generative Agents](agent_simulations/characters.ipynb): This notebook implements a generative agent based on the paper [Generative Agents: Interactive Simulacra of Human Behavior](https://arxiv.org/abs/2304.03442) by Park, et. al.

And while competitive sitting may seem harmless, there could be some unforeseen consequences. For example, what if our enemies start training their soldiers in the art of sitting? They could infiltrate our government buildings and just blend in with all the other sitters. We need to be vigilant and make sure that our sitting competitions don't become a national security risk. *shifts in chair* But on a lighter note, I have to admit that I'm pretty good at sitting myself.

Additionally, we must invest in the necessary infrastructure to support these vehicles, such as advanced sensors and communication systems. But we must also ensure that these innovations are accessible to all Americans, not just the wealthy.
