Client

A client is setup as follows if ENV['GOOGLE_API_KEY'] exists:

A client may also be passed the following options:

• api_key (required - default is ENV['GOOGLE_API_KEY'])
• host (optional)
• version (optional - options are v1 or v1beta)

Configuration

Global configuration is supported for the following options:

OmniAI::Google.configure do |config|
  config.api_key = 'sk-...' # default: ENV['GOOGLE_API_KEY']
  config.host = '...' # default: 'https://generativelanguage.googleapis.com'
  config.version = 'v1beta' # default: 'v1'
end

Chat

A chat completion is generated by passing in prompts using any a variety of formats:

completion = client.chat('Tell me a joke!')
completion.choice.message.content # 'Why did the chicken cross the road? To get to the other side.'

completion = client.chat({
  role: OmniAI::Chat::Role::USER,
  content: 'Is it wise to jump off a bridge?'
})
completion.choice.message.content # 'No.'

completion = client.chat([
  {
    role: OmniAI::Chat::Role::USER,
    content: 'You are a helpful assistant.'
  },
  'What is the capital of Canada?',
])
completion.choice.message.content # 'The capital of Canada is Ottawa.'

model takes an optional string (default is gemini-1.5-pro):

completion = client.chat('How fast is a cheetah?', model: OmniAI::Google::Chat::Model::GEMINI_FLASH)
completion.choice.message.content # 'A cheetah can reach speeds over 100 km/h.'
