AgSpec adapts retrieval-based speculative decoding to coding agents

huggingface.co by Sumin Lee et al. Editor score 8/10

AgSpec retrieves drafts from session, workspace and global corpora, then adapts draft length using verification feedback; it reports up to 4.37× throughput at batch size 1 and 4.76× at batch size 16. The results show how agent-specific context and acceptance behavior can improve inference speed.

What
AgSpec adapts retrieval-based speculative decoding to coding-agent pipelines with agent-specific corpora and draft-length policies.
Method
It retrieves from session, workspace, and global corpora; offline caps and verification feedback set draft lengths and adapt them online.
Why it matters
On two repository-level multi-agent coding benchmarks, it raises throughput over autoregressive decoding up to 4.37× at batch size 1 and 4.76× at batch size 16.
