RubyLLM 1.16: Concurrent Tool Execution + Rails-style Instrumentation + api_base support for all providers + a deluge of fixes

RubyLLM 1.16 makes your tools run concurrently in threads or fibers, makes RubyLLM observable without monkey patching, and lets every native provider sit behind a proxy.

Concurrent Tool Execution

RubyLLM.Concurrent.Tool.Executions.mp4

When a model returns multiple tool calls in one response, RubyLLM has always run them one at a time. Incredibly useful for I/O-bound tools like HTTP calls, database lookups, other LLM requests.

Turn it on for every chat from one place:

RubyLLM.configure do |config|
  config.tool_concurrency = true # :threads, :fibers, true, or false
end

true uses Ruby threads and needs no extra dependencies. :fibers mode uses the optional async gem.

You can also override it per PORO or Rails chat record, when a particular conversation needs different behaviour:

chat.with_tools(Weather, StockPrice, Currency, concurrency: true)
chat.with_tools(Weather, StockPrice, Currency, concurrency: :threads)
chat.with_tools(Weather, StockPrice, Currency, concurrency: :fibers)
chat.with_tools(Weather, StockPrice, concurrency: false)
chat_record.with_tools(Weather, StockPrice, concurrency: :threads)

Inside Rails, each concurrent tool call runs wrapped in the Rails executor, so connection pools, CurrentAttributes, and reloading behave the way the rest of your app expects.

Streaming Results as They Finish

Concurrency doesn't make you wait for the slowest tool to start showing progress. Each tool result is added back to the conversation the moment that tool finishes, in completion order. RubyLLM still waits for every result before asking the model for its next response, but your callbacks and streaming UI see results stream in as they land instead of all at once at the end.

This way, simply adding

RubyLLM.configure do |config|
  config.tool_concurrency = :fibers # or :threads
end

gives you and your users the best performance and user experience.

Rails-Style Instrumentation

RubyLLM now emits structured events for the work it does. No specific observability backend required.
