LeemerChat GA1 is now generally available, shaped by years of development and billions of tokens across chat, research, podcast, Analyst, LeemerStudio, and new model lanes.
LeemerH2 is the successor to Leemer Heavy, built as a council of models for stronger software engineering, research, verification, and 128K-token synthesis.
Leemer Analyst is a persistent research agent inside its own E2B VM, built for long-running analysis, memory, connectors, verification, and private artifact deployment.
LeemerStudio is a new creative workspace inside LeemerChat for generating images, animating references, rendering video, tracking live status, and keeping every output in private history.
We replaced every active Grok route with Grok 4.3, promoted Qwen3.6 Max Preview into the premium slot, added Qwen3.6 35B A3B, and cleaned out older Qwen/Grok baggage. Here's why.
A detailed product update after eight recent PRs: why PowerCode now lives on as Critique.sh, what changed across the app shell and settings UX, how DeepSeek V4 Flash and Pro plus Xiaomi MiMo V2.5 and V2.5 Pro landed in the lineup, and why Firecrawl now sits under the live search stack for both free and pro flows.
LeemerChat v8.0.0 retires the in-app PowerCode agent (4.9+). What it was, why Critique.sh fits review and ship work better, and what stays in main chat. Partner terms on /tips.
We refreshed our partner lineup around Chinese-led trillion-scale open models—DeepSeek V4 Pro and Flash, Xiaomi MiMo 2.5 Pro and 2.5, Moonshot Kimi K2.6, plus a time-bound free route for InclusionAI Ling 2.6 1T. Here is why we bundled them, how they differ, and how to benchmark them on real work instead of leaderboard screenshots alone.
LeemerLabs is the infrastructure arm of the Leemer Group: Ireland-hosted inference, custom model creation through LeemerFoundry, and the systems powering products like LeemerChat.
Z.AI's GLM-5.1 is the first model built for long-horizon autonomous coding — running independently for 8+ hours, planning, executing, and self-improving without human input. It beats or matches GPT-5.4 and Claude Opus 4.6 on several benchmarks. Here's why we made it free, how it compares, and why Pro still matters.
Three frontier-grade models go free — Xiaomi MiMo-V2-Pro (1M context), Z.AI GLM-5V-Turbo (native multimodal agent), and Google Gemma 4 31B IT (89.2% AIME 2026). Premium gets sharper with GPT-5.4, GLM-5, and MiniMax M2.7. Plus: why we cleaned up the lineup and what frontier actually means now.
Mission Control is our next-generation agentic research and execution platform. It represents a fundamental shift in how we interact with AI—moving away from rigid pipelines and chat interfaces, and stepping into the era of autonomous, goal-oriented swarms.
Tinker is now generally available. Vision input, Kimi K2 Thinking, and LoRA Without Regret are reshaping what custom model training looks like in 2026. Here's why fine-tuning is more strategically important than ever — and how LeemerLabs Model Foundry is building the infrastructure to prove it.
MiniMax M2.5 launches on LeemerChat with breakthrough performance in Word, Excel, and PowerPoint generation. Scoring 80.2% on SWE-Bench Verified and 76.3% on BrowseComp, M2.5 extends M2.1's coding expertise into general office productivity.
GLM-5 launches on LeemerChat with major upgrades in scale, training data, and RL infrastructure. Built for long-horizon agentic systems, coding reliability, and complex reasoning under production constraints.
We've integrated Cursor's Cloud Agents API into LeemerChat so you can launch, monitor, stop, and follow-up with autonomous coding agents on your GitHub repos — all from the chat. Just enter your API key in settings and start dispatching agents with natural language.
We've integrated Blackbox Cloud into LeemerChat so you can dispatch autonomous coding agents to your GitHub repos — single-agent or multi-launch — without leaving the conversation. Create, monitor, and cancel tasks with natural language.
What if AI answers came from a council of experts instead of a single voice? KingLeemer orchestrates multiple frontier models to think together, disagree, debate, and converge on answers more reliable than any single model could produce alone.
Kimi K2.5 brings state-of-the-art visual coding, 262K context, and self-directed agent swarms. We’re Ireland’s first AI platform to launch it — and it’s live free on LeemerChat.
Upload a PDF, get it back solved. No prompts required. Introducing our standalone PDF processing workflow with Mistral OCR, Multi-Agent Consensus, and Visual Overlay.
Introducing Codebase Chat with GitHub integration, natural AI Memory for preferences, Second Thought expert consultations, and concurrent generation. The biggest evolution of LeemerChat yet.
Google's Gemini 3 Flash represents a clear shift in how frontier-level AI is delivered in production. Near-Pro-level reasoning and multimodal understanding while remaining fast, responsive, and economical enough for large-scale deployment.
Meet RIN (凛) — a 26B-A3B MoE model running at 450 tokens/second, completely free and unlimited. The precision instrument for builders who value speed over hand-holding. Semi-successor to LeemerGLM.
This holiday season, we're reflecting on an incredible year together. From V3 to V4.9, over 1.5B+ tokens processed, LeemerLite at 1,750 T/s, PowerCode, and welcoming GPT-5.1, Claude 4.5 Sonnet, Gemini 3, and Qwen — here's to building the future together.
Discover how IKEA-inspired design, frosted glass interfaces, and revolutionary durable generation create an AI workspace that feels effortless yet powerful. This is what happens when design meets reliability.
We just dropped LeemerLite: a super-simplified, no-signup chat running gpt-oss-safeguard-20b at world-class speeds. See how it stacks up against GPT-5 Nano, Llama 4 Scout, and Mistral.
Detailed drop of research, email, and automation updates with new model lineup.
A behind-the-scenes look at how we built LeemerGLM on top of Gemma 3 4B, why we paired it with a multimodal specialist, and how it slots into our expert panel.
Vibe coding feels fast, but it hides a $50B cleanup bill. This editorial exposes why 80% of startups crash because of sloppy code and how frontier AI turns vibes into infrastructure.
The AI boom is the biggest technological surge since the internet — and it is dangerously overheated. Based on historical venture cycles, market concentration, and structural economics, 90% of today's AI companies will likely be worth close to zero by 2027. This is not pessimism. It is pattern recognition.
In a world where AI is becoming critical infrastructure, relying on third-party APIs is like renting your brain. We explore why self-hosted, sovereign AI models are the future—and why the smartest companies are already making the switch.
We're launching Ireland's first custom LLM creation studio. Fine-tune frontier models up to 235B parameters using Tinker distributed training, powered by Thinking Machines Lab. Build domain-specific intelligence layers that you own and deploy anywhere.
We tested GPT-5.1, Claude Sonnet 4.5, Grok-4.1-Fast, and Gemini 2.5 Pro across coding, reasoning, writing, vision, research, and speed. The results reveal why using multiple models in one chat is the future of AI.
How LeemerChat used BotID Deep Analysis to shut down coordinated synthetic agents without slowing down real users.
A deep dive into the union model architecture powering Leemer Heavy's iterative research orchestration and Heavy (Fast)'s rapid debate synthesis system.
