The design and implementation of the package closes follows that of "WWW::OpenAI", [AAp1];

Installation

zef install WWW::PaLM

From GitHub:

Usage examples

Show models:

use WWW::PaLM;

palm-models()

# (models/chat-bison-001 models/text-bison-001 models/embedding-gecko-001)

Show text generation:

.say for palm-generate-text('what is the population in Brazil?', format => 'values', n => 3);

# 211,768,929
# 213,317,639
# 212,609,039

.say for palm-generate-message('Who wrote the book "Dune"?');

# {candidates => [{author => 1, content => Frank Herbert wrote the book "Dune". It was first published in 1965 and is considered one of the greatest science fiction novels of all time. The book tells the story of Paul Atreides, a young man who is thrust into a war for control of the desert planet Arrakis. Dune has been adapted into a film, a television series, and a number of video games.}], messages => [{author => 0, content => Who wrote the book "Dune"?}]}

                            "wher is the best coffee made?"],

Command Line Interface

Maker suite access

The package provides a Command Line Interface (CLI) script:

palm-prompt --help

# Usage:
#   palm-prompt [<words> ...] [--path=<Str>] [-n[=UInt]] [--mt|--max-output-tokens[=UInt]] [-m|--model=<Str>] [-t|--temperature[=Real]] [-a|--auth-key=<Str>] [--timeout[=UInt]] [-f|--format=<Str>] [--method=<Str>] -- Command given as a sequence of words.
#   
#     --path=<Str>                       Path, one of 'generateText', 'generateMessage', 'embedText', or 'models'. [default: 'generateText']
#     -n[=UInt]                          Number of completions or generations. [default: 1]
#     --mt|--max-output-tokens[=UInt]    The maximum number of tokens to generate in the completion. [default: 100]
#     -m|--model=<Str>                   Model. [default: 'Whatever']
#     -t|--temperature[=Real]            Temperature. [default: 0.7]
#     -a|--auth-key=<Str>                Authorization key (to use PaLM API.) [default: 'Whatever']
#     --timeout[=UInt]                   Timeout. [default: 10]
#     -f|--format=<Str>                  Format of the result; one of "json", "hash", "values", or "Whatever". [default: 'values']
#     --method=<Str>                     Method for the HTTP POST query; one of "tiny" or "curl". [default: 'tiny']

Remark: When the authorization key argument "auth-key" is specified set to "Whatever" then palm-prompt attempts to use the env variable PALM_API_KEY.
