Finally got to record a 15 min overview of what @langfuse is based on an end-to-end example - how it helps build great AI agents/apps - how to continuously improve them with Lanfguse - how the integration works - why langfuse and no closed-source solutions - how agents use it
Replying to @marcklingen
@marcklingen sat down to demo all langfuse features in a single video. Agent observability, monitoring, evals, prompt management, and what is special about Langfuse. Great place to start if you are new, or catch up on latest changes. langfuse.com/watch-demo

What is an AI Gateway? Why did Langfuse build one? And where is it going? Our Solutions Architect @drborismichel answers all three questions in a new video. Great summary of what's live today and what's to come in the next weeks. Give it a try and tell us what you think. Feedback shapes what we build next. If you want to hear more, join our Quarterly Townhall tonight with @marcklingen to talk about our latest ships and roadmap (link in thread).

copilot/cursor Tab was the first big use case for AI that got many of us excited in 2022 today I actually wanted to edit a file myself and just found Cursor Tab to be very annoying, similar to a person that would always interrupt and try to complete what I try to say while not really getting it; I am typing myself as it is not obvious what I want to type if I type myself, I want to go for the full raw experience (like posting, ok if it has some typos, whatever), everything else will be done by an agent anyway

Kinda nuts that you don’t have to think about backwards compatibility at all with your MCP tools.

Part of why I joined @ClickHouseDB is because they do what I would do if I were running a database company. ✅Kept flagship OLAP DBMS open source. No enshitification. ✅Add verticals (agents, observability) on top of OLAP DBMS. ✅Launch Postgres service 1yr after buying PeerDB.
Today we’re announcing the largest expansion of ClickHouse since we launched ClickHouse Cloud, and we’re welcoming the @xata team to ClickHouse. ClickHouse now serves more than 5,000 customers, including DoorDash, Ramp, Meta, Tesla, Cisco, and Visa. What began as an open source analytical database is now a platform for the full set of data-intensive workloads behind modern applications. Launching today 🚀 ClickHouse Managed Postgres is generally available. ClickHouse Observability is in public beta. ClickHouse Security is in private preview. Langfuse AI Gateway is in public beta. And with the acquisition of Xata, the agent-native Postgres company, we’re accelerating instant branching, cloning, and scale-to-zero environments for developers and AI agents. Welcome, Xata! One open, composable foundation to build, observe, and secure applications. Read the full announcement: clickhouse.com/campaigns/pla…

Guess after more than 10 years without a console, I need to go shopping this weekend falling for the GTA marketing as many memories are tied to playing gta5 with brother/friends

Big open source projects should start to feel like a GTA/Fortnite game lobbies The community jamming together and having fun Massive multiplayer agent projects
Your agents can now coordinate with your teammates’ agents. Projects has been rebuilt for multiplayer: every teammate and their agents can now work together in one unified workspace.

Just recommended a friend to do a Show HN for his new security project Our initial Show HN was a huge driver of initial traction and many of the changes discussed on the thread happened over time: embrace OTel, massively scale ingestion, OLAP: news.ycombinator.com/item?id… also, @NathanFlurry called it early lol very fun to look back at where we were 3y ago

Very excited about this launch! In our team we wanted to understand whether all of our work on skills / Agents.md actually makes sense and how can optimize further 🧵
Today, we are launching Langfuse AI Gateway, in public beta. We believe every company needs a unified way to use models, track costs and govern access to AI. Change one base_URL in front of OpenAI and Anthropic, and every request becomes a Langfuse trace. 🧵

privately now switched from muse to grokbot I am so happy I liked the whatsapp UI, but Muse just routinely dropped the ball on tasks and was not able to do things in parallel which made me use chat/claude while I generally prefer grokbot UX for personal productivity

expanding into gateway market today. thousands of teams use langfuse with third party gateways already today so this is a natural extension & marks us going "multi product". self-hostable (MIT) & on cloud as you are used to. lots more to come in the cold & dark months of the year!
