Bub

A hook-first runtime for agents that live alongside people.

Very cool to see Gemma 4 12B.

We’ve tried #Bub with Gemma 4 E2B for simple on-device agentic workflows — so a stronger multimodal model for laptops and edge devices is an exciting step.

Local agents keep getting more practical.

Meet Gemma 4 12B!

A unified, encoder-free multimodal model designed to bring high-performance intelligence directly to your laptop, and released under an Apache 2.0 license.

Bridging the gap between edge efficiency and advanced reasoning. Here is what’s new with Gemma 4 12B: 👇

😜 Better observability: export data from Tape to @ArizePhoenix without any additional instrumentation— just install an otel plugin. Plus, #Bub and #Deepseek V4 Pro work seamlessly.

Tutorial 6 is live: use Bub as an #ACP agent.

Expose Bub through #agentclientprotocol, start with @zeddotdev , and keep models, tools, skills, plugins, and tapes on the Bub side.

Tutorial 4 is the wild one.

Your prompt in Go. Your llm provider in Rust. #Bub still handles the rest.

We kept Bub 's orchestration in Python. All through #WebAssembly + @extism .

oops...this is tutorial 5, 😌

Now, you can find me on https://t.co/TO6Gm3ZCEB ! Open spec make harness engineering happy.

recommend reading. LangChain has been showing how to make agents self-evaluate and self-evolve.

@bubdotbuild did something similar with https://t.co/DnuakWxEJR . It’s cool to see that in agent engineering, we’re starting to land on some shared ideas and best practices.

Tutorial: local Agents with #Bub + llama.cpp.

Whether a small local model like Gemma 4 by @googlegemma drive simple agentic workflows?

Not perfect, but surprisingly usable — and Bub’s abstraction makes it easy to experiment.

Tutorial 3 is live: #Bub with a SQLAlchemy-backed tape store.

Tape keeps the Agent model simple: append-only records for context, memory, and ops logs — whether you start with JSONL/Markdown or move to a queryable DB like #sqlite

@Ehco1996 bub 的上下文是可以放在 db 里的，我们制作了专门的 sqlalchemy 和 sqlite 插件

Part 2 of my tutorial series is LIVE!

Learn to connect ANY MCP server to Bub in minutes using bub-mcp. No more struggling with configs – just copy, paste, and run.

We now have a new plugin that brings the Model Context Protocol to #bub .

With #Bub, you can use familiar observability tools like logfire or jaeger. Of course, you can also just ask Bub what’s going on.

@pollenrobotics rm 't' in the link, it works

@sama I need a compact model that works well enough (at a lower price), and I truly hope that everyone in the world can enjoy cutting-edge technology as much as possible.

@ClickHouseDB numbers may not be exact, but a fun little reminder to celebrate.

bub just passed 10k downloads on PyPI 🎉

Many users deploy their own forks, but this still feels like a small milestone.

We’re happy to see people extend, adapt, and ship bub in their own ways.
