I benchmarked 7 browser setups for coding agents on real tasks on live websites. With Claude Sonnet 5: - @Stagehanddev: 61% - wdio session: 58% - @webdriverio MCP: 54%, cheapest per task and token - agent-browser 50% - @playwrightweb: 46%/37% benchmark.webdriver.io

I am so excited about this release @webdriverio and every single new feature 😊 If a task is verifiable, agents can do it. A lot of people are noticing that right now. So the question isn't "can the agent write the feature?" It's "how does it prove the feature works?" 🧵 1/3

🧠 Solving the Memory Problem: Introducing LangChain's Summarization Middleware in LangChain v1 alpha! Ever built an AI agent that "forgets" important context when conversations get too long? You're not alone. Token limits are one of the biggest challenges in building production-ready AI applications. The Problem: Long conversations hit token limits, forcing you to either: ❌ Truncate early messages (losing context) ❌ Manually manage conversation history ❌ Accept degraded performance as context grows The Solution: LangChain's new summarizationMiddleware automatically manages conversation memory by intelligently summarizing older messages while preserving recent context. Why This Matters: ✅ Zero Manual Work - Automatic token monitoring and summarization ✅ Smart Preservation - Never breaks AI/Tool message pairs ✅ Context Continuity - Maintains conversation flow seamlessly Real Impact: Our example shows a conversation going from ~6,000 tokens down to ~1,500 tokens (75% reduction!) while maintaining all the essential context. The agent can still reference earlier challenges and recommendations perfectly. Perfect for: 🎯 Customer support chatbots with long sessions 🎯 Code review assistants processing large codebases 🎯 Research agents analyzing extensive documents 🎯 Any multi-turn dialogue that needs persistent memory This isn't just about staying under token limits—it's about building agents that can have truly long-form, meaningful conversations without losing their memory. 📚 Read more in our new docs: docs.langchain.com/oss/javas… What's your biggest challenge with conversation memory in AI applications? #AI #LangChain #MachineLearning #Chatbots #AgentDevelopment #OpenAI #Anthropic #agents
