talkie-web-13b-it (Transformers format)
This is a conversion of talkie-lm/talkie-web-13b-base to the HuggingFace Transformers format. The original model was distributed as a raw PyTorch checkpoint with a custom inference library; this version can be loaded directly with AutoModelForCausalLM and AutoTokenizer.
[!NOTE] This base model was ported to Hugging Face format by Xiaoning Wang, based on the version automatically converted by Hugging Face's ML Intern at lewtun/talkie-1930-13b-it-hf — an AI agent for ML engineering tasks. Try it yourself via the CLI or the Demo.

Key Features
- Vintage knowledge: trained exclusively on pre-1931 text, offering a unique window into early 20th-century language and thought
- Instruction-tuned: fine-tuned for conversational use with a simple chat template
- 13B parameters in bfloat16 (~26 GB VRAM)
- 2048 token context window

Architecture Details
talkie is a 40-layer decoder-only GPT with several distinctive architectural choices:
| Component | Details |
|---|---|
| Parameters | 13B |
| Layers | 40 |
| Attention heads | 40 (MHA, no GQA) |
| Hidden size | 5120 |
| Head dimension | 128 |
| Intermediate size (MLP) | 13696 |
| Position encoding | RoPE (θ = 1,000,000) |
| Activation | SwiGLU |
| Normalization | RMSNorm (pre-norm) |
| Context length | 2048 |
| Vocabulary | 65,540 (65,535 BPE + 5 special tokens) |
| Precision | bfloat16 |
Notable architectural features:
- QK-normalization: RMSNorm is applied to queries and keys after RoPE
- Per-head gain: learnable scalar gain per attention head, applied to queries
- Embedding skip connections: each transformer block receives a residual connection from the (normalized) input embeddings
- Activation gains: learnable scalar gains on attention and MLP residual streams (initialized to (2·L)^(-0.5))
- lm_head weight gain: a learnable scalar applied to the output projection weights
Conversion Notes
This model was converted from the original talkie-lm/talkie-web-13b-it PyTorch checkpoint using the reference talkie codebase as ground truth. The conversion involved:
- Model weights: the
.ptstate dict was remapped to aPreTrainedModelsubclass (TalkieForCausalLM) and saved as safetensors - Tokenizer: the tiktoken BPE vocabulary was converted to a
PreTrainedTokenizerFastwith the HuggingFaceTikTokenConverter, including all 5 special tokens (<|endoftext|>,<|end|>,<|user|>,<|assistant|>,<|system|>) - Validation: logits were compared on 4 test prompts covering chat, system prompts, and raw completion — all top-5 decoded tokens match exactly, with cosine similarity ≥ 0.99999994
Since this is a custom architecture, loading requires trust_remote_code=True.
