ArgosBrain pushed Opus 4.7 from 87.6% to 95% on SWE-bench Verified

Learn how to improve AI coding agent efficiency by amplifying grep and Read with structural facts, reducing redundant file reads and hallucinated symbols.

Overview

ArgosBrain — structural engine for AI coding agents.
Opus 4.7 leads the GA SWE-bench Verified leaderboard at 87.6%. We’re aiming for ~95% — by amplifying (not replacing) grep and Read with ArgosBrain. Argos delivers structural facts — every symbol, every caller, every type — in under 50ms at $0 per query. Grep and Read get faster and sharper because they know exactly where to search. We’re publishing the full head-to-head: Opus 4.7 vanilla vs Opus 4.7 + ArgosBrain on SWE-bench Verified.
AI agents like Claude Code and Cursor re-read your codebase every session, burning 73% of their tokens on redundant file reads. ArgosBrain is a local Rust engine that indexes your code into a unified graph (SCIP + LSP + tree-sitter) and serves it to agents via MCP — sub-50ms symbol lookups, $0 per query, zero hallucinated symbols.
Live tested on Kubernetes (~2M LOC), VS Code, and OpenClaw. Per-task cost drops from $0.40 to $0.04 in our benchmarks.
