AstraGPTCoder-7B
Abstract
A coding-specialised sibling of AstraGPT-7B. Same base, same think-tag reasoning format, tuned with LoRA for code generation. It runs in roughly 6GB of VRAM at 4-bit quantisation, which is what makes it usable on a single consumer GPU.

Abstract
A coding-specialised sibling of AstraGPT-7B. Same base, same think-tag reasoning format, tuned with LoRA for code generation. It runs in roughly 6GB of VRAM at 4-bit quantisation, which is what makes it usable on a single consumer GPU.
Overview
AstraGPTCoder-7B is the coding sibling of AstraGPT-7B. It shares the base model and the <think> reasoning format, and was fine-tuned with LoRA on code-heavy data to improve generation, completion and explanation of source code.
The practical difference is footprint: at 4-bit quantisation the model fits in roughly 6GB of VRAM, so it runs on a single 8GB consumer card without offloading.
Specifications
| Item | Value |
|---|---|
| Base | AstraGPT-7B |
| Parameters | 7B |
| License | Apache-2.0 |
| Reasoning format | <think> ... </think> |
| VRAM at 4-bit | ~6GB |
| Training | LoRA (PEFT) on 2× RTX 4090 |
| Primary use | Code generation, explanation, refactors |
When to use it
- Code generation and completion where a local 7B is enough.
- Step-by-step explanation of unfamiliar code, using the think trace.
- Drafting tests and small refactors before a larger model reviews them.
- Not a replacement for execution: generated code still has to run and be reviewed.
Limitations
- Small-model code quality: complex repositories exceed its context and reasoning budget.
- The model card carries some older architecture notes from an earlier revision; treat AstraGPT-7B's card as the canonical configuration.
- English-primary, and no tool use out of the box.
