lexi-coder-v5.1
lexi-coder-v5.1 by Reallexi LLC AI Model Builder — llm.reallexi.io
Copyright (c) 2026 Reallexi LLC. All rights reserved.
A standalone model of 3.86B parameters, derived from reallexi/lexi-coder-v4.3.
The adapter has been merged into the base weights, so no PEFT adapter is needed at runtime.
Size and requirements
| Parameters | 3,859,090,432 (3.86B) |
| Weights on disk | 7.15 GB |
| Trained context length | 1,024 tokens |
| Base model | reallexi/lexi-coder-v4.3 |
Approximate memory to hold the weights. Add context and runtime overhead on top.
| Precision | Weights |
|---|---|
| FP16 / BF16 | 7.19 GB |
| 8-bit (Q8_0) | 3.59 GB |
| 4-bit (Q4_K_M) | 1.98 GB |
Training
| Strategy | lora |
| Adapter | Auto LoRA |
| LoRA rank / alpha | 16 / 32 |
| Dataset | reallexi/lexi-coder-v3-datasest |
| Samples learned | 110,000 (through phase 28 of 258) |
| Training steps | 15,000 |
| Epochs | 3 |
Before / after samples
The same prompts, drawn from the training data, run through the base model before training and the finished model after. This shows what the run changed on representative prompts -- it is not a benchmark. Full outputs are in SAMPLES.md and samples.json alongside this file.
