Welcome to V4

Hey friends,

Thank you for that beautiful send-off to V3. You stuck with us through every wild experiment, every late-night feature drop, and every "let's see what happens if we try this" moment. Your patience, curiosity, and hundreds of millions of tokens burned together built something special.

V4: Evolution, Not Revolution

We're not abandoning what made V3 magical—we're sharpening it. The same workshop energy that powered the Featured demos is now baked into every corner of LeemerChat V4. Here's what's new:

All-New UI & Google Sign-In

We rebuilt the interface from the ground up with the same philosophy: make powerful systems feel friendly. Clean, responsive, and faster than ever. Plus, you can now log in with Google—because nobody needs another password to remember.

Next-Generation Models

Remember when we launched that auto-router a year before anyone else? We're doing it again with V4's model lineup. You now have access to:

• GPT-5: The latest from OpenAI, delivering unmatched reasoning and creativity
• Grok-4-Fast: Lightning-quick responses without sacrificing intelligence
• Leemer Deep Research-80B: Our crown jewel—a fine-tuned Mixture of Experts model built on Qwen's architecture. It crawls your docs with Firecrawl, reasons through complex problems, and delivers answers grounded in your actual knowledge base

And yes—We Made It Even Cheaper 😹

While everyone else is raising prices, we're dropping ours. V4 launches at $14/month—that's $1 cheaper than V3. Same energy, more power, friendlier price. Because we believe the best AI should be accessible to novices and unstoppable for the ambitious.

What You Loved Is Still Here

All those breakthroughs you helped shape? They're not just preserved—they're improved:

• Auto-routing is faster and smarter, matching you with the perfect model for every prompt
• Hybrid models like Leemer-GR continue blending the best reasoning, speed, and tone
• DeepSeek-style thinking with Leemer tempo—ideate quickly, reason deeply, keep momentum
• SuperReply and AI teams orchestrate multiple agents to critique, plan, and co-write together

The Experiments Continue

V3 was our lab notebook. V4 is the production line—but the tinkering never stops. We're still learners first, still building in public, still calling ourselves novices so we can keep experimenting without ego.

That spirit isn't confined to LeemerChat anymore. It powers ask.warren.wiki,warren.wiki, usefolio.dev, and HeyCouncil. Each project carries the same mission—make advanced systems feel friendly and unstoppable.

Your Loyalty, Rewarded

To everyone who subscribed to V3: we haven't forgotten you. If you were a paid subscriber, email us at dev@leemerchat.com for a refund, plus a free month in the new V4 workspace when it launches. You believed in us when we were figuring it out—we've got your back.

Come Build With Us

V4 isn't just a new version—it's an invitation. We're opening the doors to a smarter, faster, friendlier workspace where novices feel welcome and experts feel limitless. The same place where ideas become products, where bugs get debugged, and where community beats polish every time.

Thank you for burning all those tokens with us. Thank you for believing in two proudly self-declared novices who just wanted to build something useful. V3 was your era. V4 is our next chapter together.

Welcome home. Welcome to V4.
