"Congrats on 2.0 — the BEAM's supervision and fault tolerance makes a lot of sense for agent workloads. One thing we've been tackling at ARU (aru-runtime.com) is the certification layer between agent intent and execution — validating outputs against a defined contract before they pass downstream. Curious whether Jido has opinions on output validation/certification, or if that's left to the application layer?"

I haven't used Jido for anything yet, but it's one of those projects I check in on once a month or so. BEAM does seem like a perfect fit for an agent framework, but the ecosystem seeming limited has held me back from going too far down that path. Excited to see 2.0!

Just a heads up, some of your code samples seem to be having an issue with entity escaping.

  Thank you! Fixing ...

Love this! The timing couldn't be more perfect. I had to write my agent framework with a mix of gen servers and Oban. It's honestly a pain to deal with. This looks like it will really remove a lot of pain for development. Thank you so much!

Is this anything similar at all to:

https://github.com/openai/symphony

I'm not very familiar with the space, I follow Elixir goings on more than some of the AI stuff.

It is curious... and refreshing... to see Elixir & the BEAM popping up for these sorts of orchestration type workloads.

  It’s great to see OpenAI embracing Elixir - symphony is a direct implementation of the types of things Jido can do!

  Not sure if related, but the page loads fine and then after a few seconds refreshes into a 404. I gave up trying to read the article.

    For me it just seems to keep refreshing for no reason so the page keeps jumping around. Also had to give up.

  • today at 5:29 PM

Very eager to read through your code! I read the first version and incorporated several of its ideas into our own internal elixir agent framework. (We make use of your ReqLLM package, thanks much for that!)

Congrats on the release!

• mikehostetler

  Thanks!!!

Nice work shipping this.

I’ve found the hardest part with agent frameworks isn’t model plumbing, it’s operational boundaries: how you isolate tools, enforce time/budget limits, and recover from partial failures when an agent call chain fans out.

BEAM’s supervision model feels like a genuinely strong fit for that, especially if each tool execution can be treated as a supervised unit with clear restart/escalation semantics. Curious whether you’ve seen teams default to many small specialized agents vs fewer general agents with stricter policies.

• mikehostetler

  today at 6:01 PM

  Thank you!

  Agree on operational boundaries - it took a long time to land where we did with the 2.0 release

  Too much to say about this in a comment, but take a look at the "Concepts: Executor" section - it digs into the model here

Thanks for sharing! I’ll definitely check it out.

I just LLM-built an A2A package which is a GenServer-like abstraction. I however missed that there already was another A2A implementation for Elixir. Anyway, I decided to leave it up because the package semantics were different enough. Here it is if anyone is interested: https://github.com/actioncard/a2a-elixir

    Lovely! Thanks for doing the first star!

I've been following this project for several months now and Elixir/BEAM is absolutely perfect for running agents. BEAM is so incredibly lightweight; IFYKYK. Theoretically you could run 1000s of agents on a single server. I'm looking forward to seeing what people who understand this build.

• mikehostetler

  today at 6:31 PM

  The core of Jido will run on a Raspberry Pi - we've even had people look at running Agents inside the BEAM where the BEAM is deployed on bare metal (embedded)

  The future is going to be wild

Hey I'd love to talk to people using this amazing framework!

  There’s a growing community showcase and I have a list of private/commercial references as well depending on your goals

It'd be cool to see a screenshot of what 'observer' shows as the process tree with a few agents active.

Edit: for those not familiar with the BEAM ecosystem, observer shows all the running Erlang 'processes' (internal to the VM). Here are some examples screenshots on one of the first Google hits I found:

  We have a full dashboard called `jido_studio` that will be available soon that helps visualize it.

  Teaser screenshot is here: https://x.com/mikehostetler/status/2025970863237972319

  Agents, when wrapped with an AgentRuntime, are typically a single GenServer process. There are some exceptions if you need a larger topology.

    I was curious about the actual BEAM processes though, that you see via the observer application in Erlang/Elixir.

    • mikehostetler

      today at 4:21 PM

      I'll put something together!

How do you ensure security? Does it have a proper container? Otherwise, it's impossible to prevent leaking prod secrets.

• mikehostetler

  today at 5:57 PM

  By using Signals and Plugins, all data between agents can be encrypted. I've seen a Jido implementation doing this already.

  It's use-case specific though - security is a much bigger topic then just "agents in containers"

  The point of Jido isn't to solve this directly - it's to give you the tools to solve it for your needs.

Meta curiosity… would OP care to comment on what role agents/LLMs played in crafting this library?

• mikehostetler

  today at 9:36 PM

  The original version where I laid down the overall patterns was all hand coded. This was mid 2024.

  I used Claude to learn & refine the patterns, but it couldn’t write this level of OTP code at that time.

  As models got better, I used them to find bugs and simplify - but the bones are roughly the same from that original design.

Jido is fantastic. A friend and I have been working on an OpenClaw type of tool in Elixir with Jido if anyone wants to check it out:

Going to give it a shot this weekend

  Fantastic!!! Appreciate any feedback

Where does this stand in relation to LangChain? https://github.com/brainlid/langchain

(Probably complimentary but wanted to check)

• mikehostetler

  today at 5:58 PM

  Jido originally used Langchain for LLM calls - but it wasn't a fit so I built an entire LLM client package to work with Jido called ReqLLM

  https://hex.pm/packages/req_llm

  ReqLLM is baked into the heart of Jido now - we don't support anything else

  • cpursley

    today at 7:42 PM

    ReqLLM is a key part of my stack, thank you for making it!

• neya

  today at 5:46 PM

  Elixir has a LangChain implementation by the same name. And in my opinion as a user of both, the Python version and the Elixir version, the Elixir version is vastly superior and reliable too.

  This agentic framework can co-exist with LangChain if that's what you're wondering.

  https://github.com/brainlid/langchain

• mmcclure

  today at 5:06 PM

  I went down this path a bit the other night, curious what OP's answer is. My mental model was that they could be complimentary? Jido for agent lifecycle, supervision, state management, etc, LangChain for the LLM interactions, prompt chains, RAG, etc. Looks like you could do everything in Jido 2.0, but if you like/are familiar with LangChain it seems like they could work well together.

  • mikehostetler

    today at 6:16 PM

    See my other comment, but Jido 1.0 used (Elixir) Langchain

    As LLM API's evolved, I needed more and built ReqLLM which is now embedded deeply into Jido.

Huh... excellent timing. I am working on a project that currently is handling this with bunch od npm tasks :)(I know), but it works.

Sidian Sidekicks, Obsidian vault reviewer agents.

I think Jido will be prefect for us and will help us organize and streamline not just our agent interactions but make them more clear, what is happening and which agent is doing what.

And on top of that, I get excuse to include Elixir in this project.

Thanks for shipping.

Let me guess, in the next 6 months, Elixir and Erlang becoming fashionable to build AI agents and then another hype cycle of AI usage and marketing of Elixir.

What's old is now rebranded, reheated and new again.

• neya

  today at 5:52 PM

  Elixir has always been fashionable to build high performance systems in. In fact, it is more suited for AI applications than any other language or framework because of the BEAM architecture and the flexibility of the language itself. I wish more people gave it a chance. You get insane performance at your fingertips with so much scalability out of the box and your code by default is less error prone compared to dynamic languages.

A library I'm excited to not vibecode against!
