Language

Instantiate a language model client by passing a provider name and an API token.

model = GenAI::Language.new(:open_ai, ENV['OPEN_AI_TOKEN'])

Generate embedding(s) for text using provider/model that fits your needs

result = model.embed('Hi, how are you?')
# => #<GenAI::Result:0x0000000110be6f20...>

result.value
# =>  [-0.013577374, 0.0021624255, 0.0019274801, ... ]

result = model.embed(['Hello', 'Bonjour', 'Cześć'])
# => #<GenAI::Result:0x0000000110be6f34...>

result.values
# =>  [[-0.021834826, -0.007176527, -0.02836839,, ... ], [...], [...]]

Generate text completions using Large Language Models

result = model.complete('London is a ', temperature: 0, max_tokens: 11)
# => #<GenAI::Result:0x0000000110be6d21...>

result.value
# => "vibrant and diverse city located in the United Kingdom"


result = model.complete('London is a ', max_tokens: 12, n: 2)
# => #<GenAI::Result:0x0000000110c25c70...>

result.values
# => ["thriving, bustling city known for its rich history.", "major global city and the capital of the United Kingdom."]

Chat

Have a conversation with Large Language Model and Build your own AI chatbot.

Setting a context for the conversation is optional, but it helps the model to understand the topic of the conversation.

chat = GenAI::Chat.new(:open_ai, ENV['OPEN_AI_TOKEN'])
chat.start(context: "You are a chat bot named Erl")
chat.message("Hi, what's your name")
# = >#<GenAI::Result:0x0000000106ff3d20...>

result.value
# => "I am a chatbot and you can call me Erl. How can I help you?""

Provider a history of the conversation to the model to help it understand the context of the conversation.

history = [
    {role: 'user', content: 'What is the capital of Great Britain?'},
    {role: 'assistant', content: 'London'},
]

chat = GenAI::Chat.new(:open_ai, ENV['OPEN_AI_TOKEN'])
result = model.start(history: history)
result = model.message("what about France?")
# => #<GenAI::Result:0x00000001033c3bc0...>

result.value
# => "Paris"

Image

Instantiate a image generation model client by passing a provider name and an API token.

model = GenAI::Image.new(:open_ai, ENV['OPEN_AI_TOKEN'])

Generate image(s) using provider/model that fits your needs

result = model.generate('A painting of a dog')
# => #<GenAI::Result:0x0000000110be6f20...>

result.value
# => image binary

result.value(:base64)
# => image in base64

# Save image to file
File.open('dog.jpg', 'wb') do |f|
  f.write(result.value)
end

Get more variations of the same image

result = model.variations('./dog.jpg')
# => #<GenAI::Result:0x0000000116a1ec50...>

result.value
# => image binary

result.value(:base64)
# => image in base64

# Save image to file
File.open('dog_variation.jpg', 'wb') do |f|
  f.write(result.value)
end

Editing existing images with additional prompt

result = model.edit('./llama.jpg', 'A cute llama wearing a beret', mask: './mask.png')
# => #<GenAI::Result:0x0000000116a1ec50...>

result.value
# => image binary

result.value(:base64)
# => image in base64

# Save image to file
File.open('dog_edited.jpg', 'wb') do |f|
  f.write(result.value)
end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
