Powerful Enumeration + and Functional Concepts\n```ruby\n# Advanced enumeration\nnumbers = [1, 2, + 3, 4, 5]\nresult = numbers.select(&:even?)\n .map { |n| n * 2 + }\n .reduce(:+)\n```\n\nEcosystem and Frameworks:\n1. Ruby on + Rails: Most popular web framework\n - Convention over configuration\n - + Rapid application development\n - Full-stack web framework\n\n2. Popular + Gems (Libraries):\n - Devise (Authentication)\n - ActiveRecord (ORM)\n - + Sidekiq (Background Processing)\n - RSpec (Testing)\n - Pry (Advanced + REPL)\n\nPerformance Characteristics:\n- Interpreted language with Just-In-Time + (JIT) compilation in newer versions\n- Generally slower than compiled languages\n- + Significant performance improvements in recent versions (Ruby 3.x)\n- Good + for web applications, scripting, and prototyping\n\nModern Ruby Development + Principles:\n1. Prefer Composition over Inheritance\n```ruby\n# Composition + example\nclass Report\n def initialize(formatter:)\n @formatter = formatter\n end\n\n def + generate\n @formatter.format(data)\n end\nend\n```\n\n2. Service Objects + for Complex Logic\n```ruby\nclass UserRegistrationService\n def initialize(user_params)\n @user_params + = user_params\n end\n\n def call\n ActiveRecord::Base.transaction do\n user + = User.create!(@user_params)\n send_welcome_email(user)\n user\n end\n end\n\n private\n\n def + send_welcome_email(user)\n UserMailer.welcome(user).deliver_later\n end\nend\n```\n\nStrengths:\n- + Extremely readable and expressive syntax\n- Rapid development capabilities\n- + Strong community and ecosystem\n- Excellent for web development and scripting\n- + Powerful metaprogramming\n- High developer productivity\n\nLimitations:\n- + Performance overhead compared to compiled languages\n- Memory consumption\n- + Not ideal for high-performance computing\n- Smaller job market compared to + Java/JavaScript\n\nRecommended Use Cases:\n- Web Applications\n- Prototyping\n- + Scripting\n- DevOps tools\n- Automation\n- Small to medium-scale enterprise + applications\n\nBest Practices:\n- Follow Ruby style guides\n- Use RuboCop + for code linting\n- Write comprehensive tests\n- Leverage design patterns\n- + Keep methods small and focused\n- Use meaningful variable and method names\n\nModern + Ruby (3.x) Improvements:\n- Improved performance with YJIT\n- Concurrent programming + features\n- Pattern matching\n- Endless method definitions\n- Improved type + signatures\n\nSample Modern Ruby 3.x Code:\n```ruby\n# Pattern matching\nresult + = case data\n in { name: String => name, age: Integer => age } \n \"Valid: + #{name}, #{age}\"\n in { name: }\n \"Invalid age\"\n else\n \"No + match\"\n end\n\n# Improved concurrency\nrequire ''async''\n\nAsync + do\n # Non-blocking operations\nend\n```\n\nRecommended Learning Path:\n1. + Ruby basics and syntax\n2. Object-oriented programming in Ruby\n3. Ruby on + Rails\n4. Testing with RSpec\n5. Advanced metaprogramming\n6. Performance + optimization\n7. Distributed systems with Ruby\n\nRuby continues to evolve, + maintaining its core philosophy of developer happiness while adapting to modern + software development needs."}],"stop_reason":"end_turn","stop_sequence":null,"usage":{"input_tokens":4,"cache_creation_input_tokens":2113,"cache_read_input_tokens":0,"output_tokens":1174}}' + recorded_at: Mon, 09 Jun 2025 19:02:17 GMT +recorded_with: VCR 6.3.1 diff --git a/spec/ruby_llm/providers/anthropic/chat_complete_with_prompt_caching_spec.rb b/spec/ruby_llm/providers/anthropic/chat_complete_with_prompt_caching_spec.rb new file mode 100644 index 00000000..08572bb2 --- /dev/null +++ b/spec/ruby_llm/providers/anthropic/chat_complete_with_prompt_caching_spec.rb @@ -0,0 +1,71 @@ +# frozen_string_literal: true + +require 'spec_helper' + +LARGE_PROMPT = File.read(File.join(__dir__, '../../../fixtures/large_prompt.txt')) + +RSpec.describe RubyLLM::Providers::Anthropic::Chat, '.complete with prompt caching' do + include_context 'with configured RubyLLM' + + class DescribeRubyDev < RubyLLM::Tool # rubocop:disable Lint/ConstantDefinitionInBlock,RSpec/LeakyConstantDeclaration + description LARGE_PROMPT + + def execute + 'Ruby is a great language for building web applications.' + end + end + + CACHING_MODELS.each do |model_info| + provider = model_info[:provider] + model = model_info[:model] + + describe "with #{provider} provider (#{model})" do + let(:chat) { RubyLLM.chat(model: model, provider: provider).with_temperature(0.7) } + + context 'with system message caching' do + it 'adds cache_control to the last system message when system caching is requested' do + chat.with_instructions(LARGE_PROMPT) + chat.cache_prompts(system: true) + + response = chat.ask('What are the key principles you follow?') + + expect(response.cache_creation_input_tokens).to be_positive + end + end + + context 'with user message caching' do + it 'adds cache_control to user messages when user caching is requested' do + chat.cache_prompts(user: true) + response = chat.ask("#{LARGE_PROMPT}\n\nBased on the above, tell me about Ruby") + + expect(response.cache_creation_input_tokens).to be_positive + end + end + + context 'with tool definition caching' do + it 'adds cache_control to tool definitions when tools caching is requested' do # rubocop:disable RSpec/MultipleExpectations + chat.with_tools(DescribeRubyDev) + chat.cache_prompts(tools: true) + + response = chat.ask('Tell me about Ruby') + + expect(chat.messages[1].cache_creation_input_tokens).to be_positive + expect(response.cache_read_input_tokens).to be_positive + end + end + + context 'with multiple caching types' do + it 'handles multiple caching types together' do # rubocop:disable RSpec/MultipleExpectations,RSpec/ExampleLength + chat.with_tools(DescribeRubyDev) + chat.with_instructions(LARGE_PROMPT) + chat.cache_prompts(system: true, tools: true, user: true) + + response = chat.ask("#{LARGE_PROMPT}\n\nBased on the above, tell me about Ruby") + + expect(chat.messages[2].cache_creation_input_tokens).to be_positive + expect(response.cache_read_input_tokens).to be_positive + end + end + end + end +end diff --git a/spec/spec_helper.rb b/spec/spec_helper.rb index e25f67e8..d0b50741 100644 --- a/spec/spec_helper.rb +++ b/spec/spec_helper.rb @@ -160,3 +160,9 @@ AUDIO_MODELS = [ { provider: :openai, model: 'gpt-4o-mini-audio-preview' } ].freeze + +# Models that support prompt caching +CACHING_MODELS = [ + { provider: :anthropic, model: 'claude-3-5-haiku-20241022' }, + { provider: :bedrock, model: 'anthropic.claude-3-5-haiku-20241022-v1:0' } +].freeze
