Google Open Source

Open source is free as in puppies, not free as in beer. 🐶📦 While research often looks at upstream maintenance, @sophiaiv.bsky.social studied the effort to USE open source software at scale across Google. What makes updates take days vs. hours? Dive into the data: goo.gle/cost-of-oss

467 providers serve a conformant A2A agent card. Nearly half came from a docs platform default with a single skill: read our docs. Most of the rest are agent-native companies selling company data, trust and on-chain services by the call. Conformant is not the same as useful.

How do you test and serve Agent2Agent (A2A) v1.0 agents directly from the terminal without writing custom SDK boilerplate? @meteatamel.bsky.social walks through the official A2A CLI (`a2a card get`, `a2a send --stream`, `a2a server --echo`/`--exec`, and `a2a skill`): https://goo.gle/a2a-cli-guide

Instead of going token by token, DiffusionGemma refines a 256-token block at once on the same base model as Gemma 4. In my 10-task test, it did better on copy editing and upfront counts, missed on valid JSON and reasoning, and ran slower on my Mac but much faster on a GPU.

Huge milestone for the open social web—the first dedicated AT Protocol devroom is coming to FOSDEM 2027 in Brussels (Jan 30–31)! Congrats to @viivi.rocks, @edouard.paris, and the @atproto.eu community on bringing the room together. Watch for the CfP by Oct 27!

AGNTCon + MCPCon kicks off today! 🎉 Stop by booth D5 to chat with our team about open agents. Catch Rao Surapaneni's keynote tomorrow (Oct 23, 10 AM PT). Add it to your schedule: goo.gle/4hSAgng

The goal: agents that get better at tackling unfamiliar tasks by improving their own working setup. Explore the open-source framework 👇 github.com/google-rese... #AI #AIResearch #AIAgents #OpenSource

Keeping data open is just as important as keeping source open. Source code, it could be argued, is data anyway.

Google Cloud, Red Hat and IBM release llm-d 1.0, a stable open-source inference stack. It routes requests to servers that already hold the matching cached prompt and splits prompt processing from token generation onto separate machines.

Kicking off Day 2 @ 9:15 AM with a Keynote from Bill Jia, VP of Eng, Core ML/AI, Google Cloud! 🚀 Explore PyTorch hardware heterogeneity, the TorchTPU OSS release, and how agentic workflows simplify scaling AI workloads across any silicon. goo.gle/4Aa3Mw9

​Google published a great practical guide on building a voice agent that never goes silent using ADK. ​Difinitely planning to carve out some time to explore this. developers.googleblog.com/step-by-step...

Google Research released Harness², an open-source framework that tunes an AI agent's harness — prompts, tools, memory, guardrails — instead of the model. First-party tests show gains up to 11.5 points. The catch: more runs, more API cost and no sandbox by default. techstrong.ai/agentic-ai/g...

Generative AI is reshaping open source development, and the trade-offs are starting to show. LF Research surveyed 234 OSS contributors and maintainers: 1 in 4 incoming PRs are now "AI slop," and only 1 in 3 projects have a formal AI policy. Read the full report to learn more.

Genkit Dart 1.0 brings typed agent flows and provider plugins to Flutter. Define schemas once, share types between app and server, inspect AI workflows locally. The prize is less glue code, not another model wrapper. genkit.dev/blog/genkit-...

Google’s MCP Toolbox Java SDK separates agent reasoning from controlled data access: the model selects tools while predefined queries and bound parameters constrain execution. Let AI decide intent. Let deterministic systems enforce authority. cloud.google.com/blog/topics/... #MCP #Java #AgenticAI

"Open by itself does very little, but enables a lot." At Open @ UNGA81 with @opensource.org & @creativecommons.bsky.social, our own amanda casari explored what it takes to make good on openness—from investing in vendor-neutral standards to rethinking trust & maintainer tooling in the AI era.
