In Brief
You can automatically generate compact, single-path model inference engines from a curated knowledge base using a multi-agent workflow; copying large framework source code helps shorten the work but is not required.

Key Findings
MetaInfer creates runnable, single-path inference engines by turning deployment constraints and distilled knowledge into code via a multi-agent loop (implementer, reviewer, verifier) and staged test contracts. When the knowledge base already covered a target, a zero-source approach produced engines with runtime profiles consistent with a bespoke implementation. When knowledge was missing for a new model, repeated controlled exploration and consolidation let the system learn model- and platform-specific rules and then re-generate a verified engine without consulting full framework source code. Separating implementation, specification review, and independent testing reduced self-confirming errors and enforced traceable verification. Blackboard Pattern
Key Data
1Runtime profiling used a 3×3 workload matrix: prompt lengths 11, 256, 1021 and generation lengths 256, 1024, 2048 tokens.
2Main runtime experiments ran Qwen3-8B with tensor parallelism = 4 and bfloat16 precision on the K100 platform.
3Related prior work cited a ~10% utilization improvement for a generated training engine (ForgeTrain on H100) as contextual evidence for agent-driven generation benefits.
Why It Matters
Platform engineers and ML operations teams who need compact, maintainable inference stacks can use this approach to produce tuned runners for specific hardware and models. Researchers and technical leads evaluating automation for production pipelines will value the method for its explicit verification gates and knowledge evolution loop that capture novel model or hardware rules.

Key Figures
Fig 1: Figure 1: Overall architecture of MetaInfer . The system organizes three loops around the CKB. The zero-reference generation loop generates and verifies a single-path inference engine from user constraints; the knowledge-base evolution loop supplements knowledge about new models or platforms when coverage is insufficient; and the experience-feedback loop writes reusable verification and optimization experience back into the CKB.
Fig 2: Figure 2: Zero-reference generation branch. Without actively consulting the source code of open-source inference frameworks, the forward path uses contract knowledge to drive code generation, specification review, and test acceptance. The backward path feeds failure reports, repair experience, and knowledge gaps back into the implementation workflow or the CKB.
Fig 3: Figure 3: Knowledge-base evolution branch. When knowledge coverage is insufficient, the system permits controlled exploration of external information and obtains a usable implementation through candidate generation and verification. A target model or platform is considered absorbed by the CKB only after effective information has been consolidated and revalidation passes with source-code reference disabled.

Reported experiments focus on a small set of models and two specific platforms (K100 and Z200), so performance numbers may not generalize across all hardware. The paper presents process and feasibility more than exhaustive numeric head-to-head comparisons with mainstream frameworks. The knowledge base must be curated and validated—generation depends on having accurate, testable contract knowledge, which can require human effort for novel architectures.

Methodology & More
MetaInfer uses a curated contract knowledge base (CKB) and a staged multi-agent workflow to generate compact inference engines from natural-language constraints and code fragments. Inputs include the target model, weight paths, parallelization mode, hardware, and performance goals. Agents play three distinct roles—implementation, specification review, and independent verification—and advance through staged test contracts that check unit behavior, end-to-end outputs, weight loading, and that execution follows the intended single-path design. The system enforces authenticity checks (real weights, no hard-coded outputs or external-framework bypasses) before accepting an artifact. Three experiment groups validate the approach. First, a controlled comparison showed that having full framework source as reference lowers construction cost (fewer agent steps and less editing) but is not necessary to produce a working engine. Second, a zero-reference build for Qwen3-8B on K100 (tensor parallelism 4, bfloat16) was profiled across a 3×3 prompt/generation workload and exhibited resource and throughput characteristics consistent with a tailored single-path engine. Third, when facing Qwen3.6-27B—whose architecture included new attention and normalization variants—the system ran a knowledge-base evolution loop: controlled exploration, consolidation of new rules, candidate generation, and revalidation without source reference. The result shows the approach can absorb new model and platform knowledge into reusable contracts, though scaling this to many models or diverse hardware will require more CKB expansion and automated operator tuning in future work.
