After four overhauls and millions of real-world sessions, here are the lessons we learned about context engineering for AI agents:

This post shares the local optima Manus arrived at through our own "SGD". If you're building your own AI agent, we hope these principles help you converge faster.

Honestly, I'm surprised too — that's a legacy Manus from a few versions back lol...

Happy to see Manus hitting SOTA in @scale_AI & @ai_risks' new benchmark, but that 2.5% on the Y-axis says we've still got a loooong way to go😅
Can AI automate jobs? We created the Remote Labor Index to test AI’s ability to automate hundreds of long, real-world, economically valuable projects from remote work platforms. While AIs are smart, they are not yet that useful: the current automation rate is less than 3%.

A new eval, Remote Labor Index, measures AI's ability to automate real-world, economically valuable projects from remote work platforms. Currently entirely unsaturated (max score of 2.5%) A great collaboration between @scale_AI and @ai_risks!

The all new web dev experience are now fully rolled out and available to all users. Behind it is still a unified general agent architecture, where every capability works together seamlessly: researching deeply to create sites, analyzing collected data, turning those insights

We released Manus 1.5: faster, higher quality, unlimited context, and an upgraded builder to create full apps in one prompt with backend, login, databases, AI features, notifications, and analytics.
Introducing Manus 1.5 Faster, better quality results. Unlimited context. Build full-stack web apps, with real AI features, backends, user logins, custom domains and analytics. Run your biz, start your side hustle, or just have fun. If you can dream it, Manus can build it.

Context Engineering in Manus i had a great conversation w/ @peakji abt the design of @ManusAI_HQ + how these use context engineering. wrote some notes here (video link below). https://t.co/rmTD4m37Fm

Grateful to be named in this year's MIT TR35 at 33. Fourteen years ago, I was fortunate to be on Forbes 30 Under 30 at 19. The past 14 years have been about learning, failing, and striving. Innovation is a journey, not a moment.
Yichao “Peak” Ji developed Manus, one of the buzziest AI apps of the year, in the latest project that blends his technical prowess with killer consumer instincts. We named him as one of this year’s 35 Innovators Under 35.

What's going on here @GeminiApp, aren't we supposed to be best buddies? 😂
IMO, this may be the most interesting data from our @a16z top 100 AI apps report. We looked at "Affinity Scores" for the top 6 most popular LLMs. Ex. what other apps are you most likely to have if you're a Claude or Perplexity user? This gave us mini-profiles of AI

Today a16z released the latest AI Top 50 list. As a small startup, it's truly an honor that we made it with not just one, but two products. The company is charging toward the $100M milestone, and I'm about to enter my 15th year in entrepreneurship. In the beginning, I thought

🚨 Announcing the latest @a16z top 100 AI apps! This marks the fifth edition 🎉 of our global ranking of consumer AI websites and mobile apps by usage. And in my opinion, it was our most surprising list yet! Our top takeaways + who made it 👇

Manus hits $90m run rate! Remarkable execution and a fantastic product being built in Singapore. Building exclusively on models from Anthropic, Google, and OpenAI, Manus is defining the next generation of ai powered productivity software for consumers and teams.

Just had a great conversation with @paulharapin at Stripe Tour Singapore. It's amazing to see Manus grow from launch in March to a $90M revenue run rate, with $100M just around the corner. Grateful for Stripe's strong support along the way!

Trying Manus Wide Research and loving it. If I were a product guy at that company, I’d be thinking of ways to make Manus more proactive. I’d love to have a daily or weekly call with the product where I can brainstorm research projects it could do for me then go off and do them.

With “Wide Research,” @ManusAI_HQ is bringing about a fundamental change in agentic work. I instructed the tool to scan 100 scientific articles – including titles, abstracts, authors, journals, year, number of citations, institution, and country. Everything was automatically

Wide Research is our latest exploration in agent-agent collaboration. Built on our large-scale virtualization infrastructure, Manus can now autonomously dispatch a team of homogeneous Manus agents to work in parallel and aggregate the results. While building AI agents, we've

Choose the system architecture that benefits the most from switching to a stronger model, instead of comparing design choices using the same model. I treat it as a regularization factor in context engineering. It helps you discover more robust, generalizable architectures. It
@peakji Thanks for sharing the note, super helpful! What do you mean by 'Maximize F(M_strong) - F(M_weak)'?

Forgot to include a key lesson in the blog: Context engineering can also overfit - not just to specific model families, but also to today's model limitations via premature optimization. At Manus, we never commit to an architecture based on static benchmarks. Instead, we treat

Thinking of you guys, while the rest of us are squashing bugs back in Singapore. 🫠
We were excited to meet with @satyanadella and the team in Seattle last week - and are excited for our partnership ahead!
