# Lovelace-1-7B

*A research-oriented code language model focused on realistic software reasoning*

---

## Model Summary

**Lovelace-1-7B** is a 7-billion parameter, code-focused large language model based on
[`bigcode/starcoder2-7b`](https://huggingface.co/bigcode/starcoder2-7b).

It is part of the **Lovelace** model family, which focuses on building **scalable, engineering-aligned coding models** intended for long-term use in tooling, agentic systems, and research environments.

Rather than optimising for short-term benchmarks, Lovelace prioritises **correctness, constraint awareness, and system-level reasoning**.

---

## Model Family

| Model             | Base Model        | Parameters | Status       |
| ----------------- | ----------------- | ---------- | ------------ |
| Lovelace-1-3B     | StarCoder2-3B     | 3B         | Released     |
| **Lovelace-1-7B** | **StarCoder2-7B** | **7B**     | **Released** |
| Lovelace-1-15B    | Planned           | 15B        | Planned      |

All Lovelace models are designed to remain interface-compatible with the **Lovelace Code** runtime.

---

## Architecture

* **Base architecture:** Transformer (decoder-only)
* **Foundation model:** StarCoder2-7B
* **Training paradigm:** Continued pretraining and alignment for code-centric tasks
* **Modalities:** Text (code and natural language)
* **Tokenisation:** Inherited from StarCoder2

The architectural design closely follows StarCoder2-7B to preserve its strong multilingual and multi-language coding capabilities, while enabling future extensibility.

---

## Intended Capabilities

Although formal benchmarks are not yet published, Lovelace-1-7B is designed for:

* Code generation and completion across multiple programming languages
* Code refactoring and explanation
* Debugging and error localisation
* API usage reasoning and software design discussion
* Identifying infeasible or unrealistic engineering requests and responding with viable alternatives

The model is explicitly tuned to **avoid hallucinated implementations**, preferring transparent limitations and constructive guidance.

---

## Lovelace Code Library

Lovelace-1-7B is intended to be used alongside **Lovelace Code**, a companion library providing:

* Structured coding prompts and system templates
* Long-request handling and staged generation
* Guardrails for non-computable or impractical tasks
* Integration points for execution, tooling, and agent frameworks

Current development focuses on **stability for long requests**, including multi-file generation and iterative refinement workflows.

---

## Evaluation

At present:

* No public benchmark results are released
* Internal evaluation focuses on qualitative correctness, coherence under long prompts, and tool-aligned behaviour

Formal evaluation and transparent reporting are planned future work.

---

## Limitations

* Long-context stability is still under active development
* No vision or multimodal support at this stage
* Performance characteristics may differ from StarCoder2-7B depending on downstream usage

Users should evaluate the model carefully before deploying in production or safety-critical environments.

---

## Roadmap

Planned improvements include:

* Improved long-context stability in Lovelace Code
* Release of **Lovelace-1-15B**
* Vision-language support (code + visual inputs)
* Public benchmarks and technical reporting
* Deeper integration with agentic and execution-based systems

---

## Intended Use

Lovelace-1-7B is suitable for:

* Research into code-focused LLM behaviour
* Developer tooling and agent-based coding systems
* Educational and exploratory programming assistance

It is **not intended** for autonomous execution or high-risk domains without additional safeguards.

## Acknowledgements

Lovelace-1-7B builds directly on the work of the **BigCode** project, specifically
[`starcoder2-7b`](https://huggingface.co/bigcode/starcoder2-7b).

The Lovelace project draws inspiration from modern open-weight research releases and large-scale industrial coding systems.
