Langfuse is an open-source LLM engineering platform designed to help developers build, debug, and optimize large language model applications
Stronger traffic
Langfuse is an open-source LLM engineering platform built for developers who create, debug, and optimize applications powered by large language models. It gives teams working with LLMs the visibility and tooling needed to move an AI feature from prototype to production with confidence.
What Langfuse Does
Provides observability into LLM application behavior for developers building on top of language models
Supports debugging of LLM-powered applications to identify issues in prompts, chains, or outputs
Helps optimize LLM applications over time based on observed performance
Is distributed as open-source software, allowing developers to inspect, self-host, or extend the platform
Who Uses Langfuse
Langfuse is aimed at developers and engineering teams building products on top of large language models. It fits teams that need to understand what their LLM application is doing in practice, troubleshoot unexpected or incorrect outputs, and refine prompts or application logic based on real usage rather than guesswork.
For makers shipping LLM-based features, Langfuse fits into the engineering workflow as the layer that sits between building a prototype and trusting it in production, giving visibility into how the application behaves so issues can be caught and addressed before they reach end users.
Seedance 2.5 online — generate 30-second 4K AI videos with up to 50 multimodal references. Text, image, audio, video & 3D blockout input. Free credits in browser.
Seedance 2.5 AI Video Generator is the upcoming generation of the Seedance AI video model, designed for longer, more controllable, and more consistent AI video creation. According to the current Seedio preview, the model is expected to support up to 30-second native video generation, as many as 50 multimodal references, and improved prompt adherence compared with Seedance 2.0.
Seedance 2.5 is currently marked as coming soon, so the platform mainly provides a preview of its expected capabilities while users can continue using Seedance 2.0.
How does Seedance 2.5 work?
Seedance 2.5 is designed around a multimodal video generation workflow. Users will be able to describe a scene through text and combine different reference materials to guide characters, environments, motion, camera direction, and overall visual style.
Key capabilities highlighted on the current page include:
30-Second Native Clips: Generate a complete video of up to 30 seconds in a single pass.
Up to 50 Multimodal References: Combine text, images, audio, source video, and 3D blockouts in one project.
Finer Camera Control: Use instructions such as dolly movements, holds, and timed camera actions.
Improved Prompt Adherence: The site claims roughly 20% better prompt adherence compared with Seedance 2.0.
Multi-Shot Character Consistency: Use reference materials to maintain a character across different angles, lighting conditions, and scenes.
Multiple Output Formats: The preview lists 720p, 1080p, and native 4K, alongside 16:9, 9:16, 1:1, and 4:3 aspect ratios.
Multilingual Prompts: English, Chinese, Japanese, and Korean are listed as supported prompt languages.
The planned workflow is simple: describe the shot, attach relevant references, select the desired format, generate the video, and then refine specific elements when necessary.
Who is Seedance 2.5 for?
Seedance 2.5 is positioned for content creators, filmmakers, marketing teams, brands, creative agencies, and independent studios. A 30-second generation window could be particularly useful for social videos and advertising, while multi-reference control could help filmmakers with pre-visualization and brands maintain consistent characters, products, locations, and visual styles across different shots.
Overall, Seedance 2.5 AI Video Generator is positioned as an upcoming upgrade focused on longer video generation, multimodal reference control, stronger prompt adherence, character consistency, and more precise cinematic direction. Since the site currently labels Seedance 2.5 as “coming soon,” these features should be treated as previewed capabilities until the model's official availability is confirmed.
