Fit your budget
Set a token limit for the selected context, including citations. Reserve space separately for your prompt and model response.
CIGAR · v0.10.0 beta 1
The right context. Within your budget.
CIGAR selects relevant information from your documents and code, keeps source citations, and fits it into the context budget you set.
Open source · Rust-powered · Apache-2.0
Add your sources
Pass in the documents or code your agent needs.
Set a question and budget
CIGAR selects relevant information that fits.
Use the cited context
Send the result to your model with its source references.
WHY CIGAR
Useful context, less manual assembly.
Keep the source
Trace selected information back to its document or code. Inspect what your agent receives before it calls the model.
Update what changed
Replace a source as it changes. The local graph updates its index without rebuilding everything.
TRY V0.10.0 BETA 1
Add CIGAR to your application.
The new Python and TypeScript SDKs run the same Rust context graph locally. No server or API key needed.
Beta for Apple-silicon Macs (macOS ARM64). For evaluation; not yet production-ready.
