MiniMax M3 also a good model for agentic workload🙌
M3 would never 🙂‍↔️ As a matter of fact, the weights are now open, too. huggingface.co/MiniMaxAI/Min…

0.3.9 is out. This release adds turn admission hooks, lifecycle channel startup control, Telegram rich messages, and several fixes. We’re also preparing #Bub 0.4.0 with more compact and effective designs. github.com/bubbuild/bub/rele… #AIAgents #Python #OpenSource

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. bub.build/docs/tutorials/acp… Expose Bub through #agentclientprotocol, start with @zeddotdev , and keep models, tools, skills, plugins, and tapes on the Bub side. #AIAgents #OpenSource

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 . Read it: bub.build/docs/tutorials/lan… #harness #agent

recommend reading. LangChain has been showing how to make agents self-evaluate and self-evolve. @bubdotbuild did something similar with tape.systems . 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. bub.build/docs/tutorials/loc… #Agent #LocalAI

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 bub.build/docs/tutorials/tap… #python #agent #llm

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. Get the guide: bub.build/docs/tutorials/mcp… #MCP #Bub #AI #DevTools #Python
We now have a new plugin that brings the Model Context Protocol to #bub . #python #mcp #agent

With #Bub, you can use familiar observability tools like logfire or jaeger. Of course, you can also just ask Bub what’s going on. otel exporter powered by @pydantic logfire Read More 👇

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. pypi.org/project/bub/ Data screenshot via ClickPy by @ClickHouseDB
