⚠️ IMPORTANT NOTICE
- This model is experimental. Glint-1 is a 1M parameter research model designed for architectural experimentation.
- Performance characteristics: The model exhibits behavioral patterns comparable to ~2M parameter models despite its compact size.
- Not production-ready: This release demonstrates functional capability, not optimal performance.
Glint-1 is an ultra-compact language model developed by CompactAI following our rebrand initiative. This 1M parameter model demonstrates that efficient architectural design can yield behavioral characteristics typically associated with larger models (~2M parameters).
This release includes both Pretrained Weights (base language modeling) and Instruction-Tuned Weights (fine-tuned for conversational tasks).
| Parameter | Value |
|---|---|
| Architecture | Transformer Decoder |
| Parameters | ~1M |
| Effective Behavior | ~2M parameter equivalent |
| Context Length | 2,048 tokens |
| Vocabulary | Standard |
| Normalization | RMSNorm |
| Activation | SwiGLU |
Glint-1 has been evaluated on standard language modeling and reasoning benchmarks:
Grammaticality minimal pairs across 67 paradigms. Accuracy measured as % grammatical < ungrammatical perplexity.

Multiple-choice science QA (~2.4K questions) using perplexity-based answer selection.

Language modeling perplexity on Wikipedia test split. Lower is better.

| Parameter | Value |
|---|---|
| Batch Size | 48 |
| Learning Rate | 8e-4 (pretrain), 2e-4 (SFT) |
| Warmup | 300 steps |
| Weight Decay | 0.02 |
| Max Grad Norm | 1.0 |
This model is released for research purposes. While functional, users should not expect state-of-the-art performance. The model demonstrates that compact architectures can achieve reasonable behavioral characteristics, making it suitable for:
