A note on the Pharo 14 release

by Esteban Lorenzano

Hello Pharo users and developers, You may have noticed that our usual AprilâMay release did not happen this yea. We wanted to explain why Pharo 14 has been delayed, and why we are still not quite at the point where we want to release it. There is not much mystery: we got very ambitious about what we wanted to include. We are still finishing a few important pieces that we believe need to be part of this release, as they will provide foundations for the next development cycle. Here is a non-exhaustive list of what we are aiming to include: * Massive changes in the VM (v12) * Migration to SDL3 as the backend * Alexandria, as a future replacement for Athens * A Bloc preview â yes! * Toplo, the new widget set based on Bloc, and a SpecâToplo preview * And many other things that are not polished enough yet So, yes, we are disappointed not to have met our usual release cycle. But we believe the extra time will be worth it â once we get there :) Cheers, Esteban

Re: An Inference engine inside Pharo for LLMs

by S Krish

Great work. Will try it out sometime ahead. My notes from few months back: """ Pharo can offer new possibilities . LLM : processing of intent into code sent to pharo agents. All of non deterministic/ deterministic logic that is transformed to code to operate on input data Pharo agents: live environment that compiles in fraction of seconds.. perhaps milliseconds. Runs instant unit tests. Distribute verified runtime patch to other agents .. rather than messy library for everything like java/ python scaffold everything from its memory Object datastore: zero impedance non relational exactly mapped object data store with all of ACID properties if needed """ On Fri, 26 Jun, 2026, 03:20 omar abedelkader, <omar.abedelkader(a)inria.fr> wrote: > Hello everyone, for the first time, we have the first prototype of an > inference engine without any connection to any of the external provider > like Ollama, LMStudio, or vLLM. > > [image: pharo-infer.png] > > pharo-llm/pharo-infer: pharo-infer is a inference engine inside Pharo > <https://github.com/pharo-llm/pharo-infer> > github.com <https://github.com/pharo-llm/pharo-infer> > <https://github.com/pharo-llm/pharo-infer> > > > > [image: Capture dâeÌcran 2026-06-25 aÌ 23.40.41.png] > â > OA > >

An Inference engine inside Pharo for LLMs

Hello everyone, for the first time, we have the first prototype of an inference engine without any connection to any of the external provider like Ollama, LMStudio, or vLLM. https://github.com/pharo-llm/pharo-inferï¿¼ pharo-llm/pharo-infer: pharo-infer is a inference engine inside Pharo github.com ï¿¼ â OA

ANN: pharo bindings for QREncode

by Esteban Lorenzano

Hello, Looking for small examples for (one of) my ESUG talks, I generate bindings forÂ this small tool: https://fukuchi.org/en/works/qrencode/ You can have things like this: https://github.com/pharo-cig/pharo-libqrencode I think it can be pretty useful :) Cheers ! Esteban

Re: "Claude, My New Pair Programming Partner" â New blog post on all: objects all: theTime

by Aaron Wohl

No matter how bad you think AIs are, I think there are some areas they are always useful: - scaffolding -- I have seen large projects fail because the later phases couldn't start until it was too late. If you have a good spec for a big project and all the interface points, an AI is great for making temporary working implementations of all the parts. Although it can raise amuzing questions when a 6-month 2-person project has a 100% working scaffold in a weekend. - Code reviews with an LLM. An agent has a limited token space. But with a custom LLM looking things like code vs comment discrepancies, it can turn up a lot of issues. ----- Original message ----- From: Esteban Lorenzano via Pharo-dev <pharo-dev(a)lists.pharo.org> To: pharo-dev(a)lists.pharo.org Cc: Esteban Lorenzano <estebanlm(a)netc.eu> Subject: [Pharo-dev] Re: "Claude, My New Pair Programming Partner" â New blog post on all: objects all: theTime Date: Sunday, June 07, 2026 12:39 PM I like what Linus Torvalds say here : https://thenewstack.io/torvalds-ai-programming-productivity/ In the best of cases, is a productivity tool.

in fact Linus says AI may increment productivity x10, but compilers did it x1000, so we are not quite close :) Esteban On 6/7/26 18:47, Nicolas Anquetil wrote: > > may be AI will allow us to raise the level of abstraction, just as > compilers, or OO did ? > > We (humans) will still program (through AI) but the programming > language will be different > > nicolas > > On 2026-06-07 18:39, Esteban Lorenzano via Pharo-dev wrote: >> >> I like what Linus Torvalds say here : >> https://thenewstack.io/torvalds-ai-programming-productivity/ >> >> In the best of cases, is a productivity tool.

may be AI will allow us to raise the level of abstraction, just as compilers, or OO did ? We (humans) will still program (through AI) but the programming language will be different nicolas On 2026-06-07 18:39, Esteban Lorenzano via Pharo-dev wrote: > > I like what Linus Torvalds say here : > https://thenewstack.io/torvalds-ai-programming-productivity/ > > In the best of cases, is a productivity tool.
