- Esper 4, our flagship agentic coder: specialist in coding, architecture, DevOps, and MLOps! - Tachibana-Agent, trained only on code for dedicated, predictable deployment!
We'll be expanding Esper 4 to more models and releasing new models as funding allows - donate for more, faster, better models and datasets: sequelbox/SupportOpenSource
Inspect model quantization in the browser, without download
Curious how models on Hugging Face spend their "bit budget"? A few days ago I shared the first version of a little tool I built out of my own curiosity (and for fun). Since then, thanks in large part to great feedback from people here, a lot has changed.
New in the last few days: - GGUF support - handy with all the new great GGUF quants - Decode for AWQ, GPTQ, NF4, mxfp4 packed experts, packed-int32, and additive-codebook formats - Improved comparison view for diffing two quants of the same model - Built-in anonymous report-issue button connecting a report to specific model - plus many small fixes
After my first post I got great feedback from several community members, and some issues were fixed within hours. I'm planning an acknowledgments section on the site, and when you report an issue you get a receipt ID you can keep to claim credit later. (reports are anonymous by design; I store no identity, so the receipt hash works like a bearer token for your find)
It's still very much a side project I hope others find useful. Explore any HF model in the browser without downloading it, the webpage reads from the safetensors header via a range request, and only tensors you click stream, and large ones are sampled, not downloaded in full. And there is a report button right in the tool when things donβt look right.
Feedback very welcome, especially models that break it :) Or ideas on what is missing.
Meta released Muse Glimmer 30B on Aug 10. We fine-tuned it the next day.
Not the full-precision weights directly β the unsloth bnb-4bit quantized re-upload (unsloth/Muse-Glimmer-30B-unsloth-bnb-4bit), which is what makes a 24h turnaround possible on a single GPU at all. Worth saying plainly: Meta's own official repo (meta-models/Muse-Glimmer-30B) still shows no download data β it's that fresh.
What we tuned it on: not new facts, a pattern. LoRA on ~194 examples teaching the difference between citing real proof, honestly declining when there's no data, and fabricating β confident or hedged, doesn't matter which.
Results on 20 held-out claims never seen in training: - base model: 0/20 - tuned: 20/20
Training: 472.5s, loss 0.799 β 0.086.
Open-ended test (not multiple choice β the model answering in its own words): base confabulates specific numbers mid-reasoning on questions it can't actually answer. Tuned: declines cleanly, every time.
Same non-fabrication pattern also holds on Hermes-3-8B and Qwen2.5-7B, tested with the identical held-out set. Effect size varies a lot by base model β one of them barely moved (base was already close to ceiling on this exact task). More on that soon.
i go to huggingface, look on spaces just to see whats new and i see that MY OWN space is trending. ProCreations/maple-webgpu very cool to see, on the very first page of spaces too. anything is possible in the open source community!
bench-labs developed **GCTokenizer-v1**, which is a multi-lingual tokenizer Available in four sizes: 32K, 65K, 131K and 262K tokens "S, M, L, XL" It utilizes an encoding scheme which allows it to handle characters in any language around the world
General (multi lingual) Consensus (from multiple model tokenizers consensus) Tokenizer
We included an implementation script too, built like BPE- it can encode arbitrary text, most of the time, efficiently
Introducing Unsloth Desktop π¦₯ The first desktop app to run and train models locally.
β’ Open-source. Runs on Mac, Windows and Linux β’ Supports MLX, diffusion image/video, audio, GGUF β’ Connect Claude Code and Codex to local LLMs β’ 50% more accurate, self-healing tool calls + sandboxed code exec β’ Works for CPU + multiGPU setups - NVIDIA, AMD, Intel, Mac β’ Train models 2Γ faster with 70% less VRAM β’ Private web search, deep research, RAG, MCP and exports (NVFP4, GGUF) β’ Use Unslothβs OpenAI-compatible API and cloud models β’ Securely deploy LLMs remotely and access anywhere
So far I've been pointing it at Markdown Minimap, an Obsidian plugin that adds a scrollable IDE-style minimap to your notes. This week I've been clearing a backlog of user-reported issues on it, with Claude often handling them end to end.
