BlazerApex-2B (IQ4_XS)

BlazerApex-2B é um modelo de linguagem ultracompacto (2.5B parâmetros), altamente otimizado e fine-tuned com foco total em Português do Brasil (PT-BR), Programação, Lógica e Matemática.

Projetado especificamente para ser o SOTA (State-of-the-Art) de bolso, este modelo roda 100% offline, de forma rápida e fluida em smartphones intermediários (como o Motorola Moto G34 5G com Snapdragon 695), sem precisar de internet ou servidores externos.

Como usar no Celular (Android)

Este repositório contém a versão quantizada IQ4_XS (~1.4 GB), ideal para dispositivos com 4GB a 8GB de RAM.

  1. Baixe o arquivo BlazerApex-2B-IQ4_XS.gguf direto no seu celular.
  2. Instale o aplicativo Maid ou Layla na Play Store.
  3. Abra o app, vá em "Models" (Modelos) e importe o arquivo .gguf baixado.
  4. Pronto! Configure a temperatura entre 0.2 e 0.7 e comece a conversar, programar ou resolver problemas de lógica offline.

Sobre o Treinamento

O BlazerApex-2B foi construído sobre a excelente arquitetura base do openbmb/MiniCPM5-2B, utilizando técnicas avançadas de LoRA (Low-Rank Adaptation) no Kaggle (2x NVIDIA Tesla T4).

Mix de Dados (Dataset)

O modelo foi treinado com um dataset híbrido e balanceado (80% PT-BR / 20% EN) para garantir fluência nativa em português sem perder a capacidade de sintaxe de código em inglês:

  • Nemotron-SFT-PT-BR-v2-Filtered (~15k exemplos): Programação e matemática estruturada em PT-BR.
  • orca-math-portuguese-64k (~15k exemplos): Raciocínio matemático passo-a-passo (Chain-of-Thought) adaptado para PT-BR.
  • wikipedia-pt-br-instructions-sft (~850 exemplos): Extração estruturada de informações e conhecimento geral.
  • wikipedia-rag (~3k exemplos): Regularização de leitura de contexto longo.
  • Qwen3.8_Max_DeepSeek_Distillation_PT-BR & BlazerDataset-PT-BR (~250 exemplos): Destilação complexa, identidade do modelo, saudações e lógica agêntica.
  • ChatGPT-Jailbreak-Prompts (~80 exemplos): Treinamento de segurança e recusa firme contra engenharia social em PT-BR.
  • Ox-Alpha-10k (~3k exemplos): Âncora em inglês puro (Go, Rust, C++, Python) para blindar a sintaxe exata de programação.

opt-125m

AI at Meta

OPT was first introduced in Open Pre-trained Transformer Language Models and first released in metaseq's repository on May 3rd 2022 by Meta AI. Disclaimer: The team releasing OPT wrote an official model card, which is available in Appendix D of the paper. Content from this model card has been written by the Hugging Face team. To quote the first two paragraphs of the official paper OPT was predominantly pretrained with English text, but a small amount of non-English data is still present within the training corpus via CommonCrawl. The model was pretrained using a causal language modeling (CLM) objective. OPT belongs to the same family of decoder-only models like GPT-3. As such, it was…

Chirp Chirp! We are introducing Ornith-1.5, a major step toward building foundation models through end-to-end self-improvement. Ornith-1.5 extends Ornith-1.0 (which was developed on top of Qwen3.5 and Gemma4 with additional continued pretraining, mid-training, and post-training) by expanding the self-improvement loop from scaffold and rollout optimization to jointly optimizing task generation, scaffold construction, and solution rollouts. Rather than relying on a fixed set of human-curated tasks and manually designed harnesses, Ornith-1.5 continuously generates new training tasks, discovers effective strategies for solving them, and improves the policy through reinforcement learning.

Ornith-1.0-9B-GGUF

Ornith

Aloha! Today, we are releasing Ornith-1.0, a self-improving family of open-source models for agentic coding. This model card documents Ornith-1.0-9B, the most lightweight member of the Ornith family, designed for efficient single-GPU deployment. Ornith-1.0-9B is a dense ~9B model (≈19 GB in bf16), so it serves comfortably on a single 80GB GPU. The recipes below stand up an OpenAI-compatible server; add --tensor-parallel-size / --tp if you want to shard across more GPUs. For a quick local test (or to script offline generation), load the model directly with Transformers. Make sure you have a recent release installed — see the Transformers installation guide; Ornith-1.0-9B requires…

Uncensored Qwen3.8-27B, published as GGUF quantizations with the multi token prediction (MTP) head retained and verified. Refusal behaviour has been substantially reduced, not eliminated. See Measured behaviour for the numbers. Capabilities, training data, and architecture are otherwise unchanged. - Refusal directions removed with Heretic, which co minimizes refusal count against KL divergence from the base model. No handwritten refusal removal code, no finetuning, no additional training data. - Abliteration runs at bf16 (no 4 bit quantization). the resulting LoRA is merged into the bf16 base, so the published weights are not a quantized round trip. - mtp. tensors are copied verbatim from…
