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.

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.

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