Model overview
The smallest member of the Lemma model family by Lethean. An EUPL-1.2 fork of Gemma 4 E2B with the **Lethean Ethical Kernel (LEK) merged into the weights** — consent-based reasoning baked into the attention projections via LoRA finetune, then merged so inference uses a single standalone model with no PEFT runtime required. This repo ships the **GGUF multi-quant build** — five quants from Q3_K_M up to BF16, with full multimodal support (text, image, audio). Use with Ollama, llama.cpp, GPT4All, or LM Studio. The unmodified Gemma 4 E2B fork lives at LetheanNetwork/lemer for users who want the raw Google weights without the LEK shift. **Looking for MLX?** The native Apple Silicon builds live in sibling repos: `lthn/lemer-mlx` (4-bit default) | `lthn/lemer-mlx-8bit` | `lthn/lemer-mlx-bf16` (full precision)

Limitations & considerations
Sources are insufficient to establish specific limitations. Verify task performance, latency, data policies, licensing and version lifecycle.
Source prices & cost analysis
Prices vary by channel, region and configuration. Channel quotes are listed independently and are not treated as a single official provider price.

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
