ColGrep Agent 2B
by LightOn AI
ColGrep-Agent-2B is a specialized 2-billion-parameter open-weight model released by LightOn AI on October 12, 2026, designed as a local code-localization subagent. It performs repository-level code search to reduce expensive API calls to primary coding agents, supporting integrations with Claude Code, Codex, and OpenCode. Vendor-reported evaluations show 34% API-token reduction and 40% cache-aware cost reduction across 52 questions in 13 repositories.
Primary Use Cases
- Repository-level code search and localization
- Reducing API costs in coding agent pipelines
- Local code navigation for large codebases
- Subordinate agent in multi-agent coding workflows
✅ Strengths
- Narrow specialization enables high efficiency for code localization tasks
- Small model size (2B) enables local deployment on modest hardware
- Vendor-reported 34% API-token reduction (label: vendor evaluation, not independently validated)
- Complements rather than replaces primary coding agents
⚠️ Limitations
- Designed as a subordinate agent, not a standalone coding assistant
- Performance figures are vendor-reported across limited evaluation set (52 questions, 13 repos)
- Requires integration setup with primary coding agent
