OpenSource Monitoring, Evaluating & Optimization for your LLM-apps
Today, LLM testing is often scattered across notebooks, dashboards, and scripts, making it slow, unreliable, and difficult to scale effectively.
We’ve heard the same pain points from teams struggling with LLM performance testing:
"I don't have a dataset to evaluate yet"
"How can we measure the quality when there is no defined golden answer in our case?"
"I have no idea how we should get started with evals, should we use LLM-as-a-judge?"
LangWatch brings you a smarter, and more reliable way to test and optimize your LLMs.
Here’s what you’ll love about the newest release of LangWatch: The Evaluations Wizard:
Build your own Evaluators: Use 50+ built-ins, LLM-as-a-judge, your own, or a human-in-the-loop review.
Evaluate full pipelines: Chain LLM calls together and test across realistic, multi-step workflows.
Launch in minutes: Upload test data, generate synthetic examples, or connect your pipeline—no setup headaches.
DSPy optimizers built-in: Optimize prompts and model configs programmatically, directly in LangWatch.
CI/CD Ready: Run batch tests via SDKs or CLI and get detailed reports, costs, and latency fast.
Whether you're an AI developer, AI PM, domain expert or any other person involved in building LLM-apps this is your new command center for LLM quality.
This is a big change in how teams will be Evaluating the performance of their LLM-apps.

Key Points
AvatarFX lets users animate AI characters and real images, offering more than just basic text-to-video generation.
Character.AI says it will watermark videos, block animations of minors, and filter celebrity images to prevent misuse.
🤖News - Character.AI, the platform known for letting users chat and roleplay with AI-generated characters, has announced a new tool called AvatarFX. Now available in closed beta, AvatarFX can animate characters in a range of styles and voices, from realistic human figures to 2D animal cartoons.
🤔What's the most interesting point here? Unlike OpenAI’s Sora, AvatarFX is not limited to just text-to-video. It also lets users animate existing images, including photos of real people.
📽️Say hello to AvatarFX — our cutting-edge video generation model. Cinematic. Expressive. Mind-blowing. Dive in: character-ai.github.io/avatar-fx/ #CharacterAI#AvatarFX

😵💫Why this is problematic - While the technology opens up creative possibilities, it also raises some serious concerns. People could upload photos of celebrities or individuals they know and create videos where they appear to do or say things they never actually did.
Although deepfakes have been around for some time, building this kind of tool into a widely used platform like Character.AI could make it easier for the technology to be misused.
🙄Safeguards are promised, but questions remain - To address these risks, Character.AI says it will watermark all AvatarFX videos to show they are AI-generated. The company also plans to filter and modify images of real people, block the animation of minors, and restrict the generation of videos featuring major celebrities and politicians.
But since AvatarFX is still in limited testing, it remains to be seen how well these safeguards will work in practice.
We just dropped the 16th edition of Workflow Wednesday—built for AI-minded professionals who want to do more than just read about AI.
This week’s theme: AI Learning That Sticks
Sharpen your prompting skills with LearnPrompting.org, turn Jenni AI into your personal research + writing assistant, and set up an automated AI-powered reading list with Notion, Zapier, and ChatGPT.

Key Points
Grok Vision lets users point their phone at objects and ask questions, similar to other real-time vision tools.
xAI also launched multilingual audio support and real-time search in Grok’s voice mode, expanding user capabilities.
Android users must subscribe to xAI’s $30/month SuperGrok plan to access the latest voice features.
☕News - xAI launched Grok Vision, a feature that lets users point their phone’s camera at objects like products, signs, and documents, then ask questions about them. This is similar to the real-time vision features already available in tools like Google’s Gemini and ChatGPT.
For now, Grok Vision is available on the iOS version of the Grok app, but Android users will have to wait a bit longer.
