What the models credit SP1 (#1) with — and don’t credit OpenVM
- standard Rust toolchain compatibility GPT · Claude · Gemini · Grok“standard Rust toolchain compatibility”
- Succinct Prover Network GPT · Claude“pairs with the Succinct Prover Network so teams get decentralized proving capacity without running GPU fleets”
- deepest production footprint Claude · Grok“the deepest production footprint”
What would move the rank — the models’ fix lines, unified
- engineering and security-review burden GPT · Claude · Gemini“engineering and security-review burden”
- rougher developer experience GPT · Claude · Gemini“rougher developer experience than SP1/RISC Zero”
- higher build-and-maintenance overhead GPT · Claude · Gemini“a much higher build-and-maintenance overhead than all-in-one monolithic zkVMs”

Exceptional for teams needing a production-oriented, customizable zkVM: modular instruction extensions, efficient cryptographic accelerators, GPU proving, unbounded execution, Ethereum verification, external audits, and formal verification of its RV32IM extension.
Claude The modular architecture play — a no-CPU, extension-based framework where you compose exactly the instruction sets and precompiles your workload needs (Keccak, pairing, modular arithmetic, ECRECOVER), yielding excellent performance on specialized workloads; MIT/Apache licensed and adopted for serious production use (e.g. Scroll's zkEVM direction).
Gemini Provides an open-source, modular, CPU-less framework using independent executor chips, enabling developers to easily customize or extend instruction sets for specialized offchain workloads.
Where OpenVM falls short, per the models
- GPT Its configurable architecture adds engineering and security-review burden, so it is not the simplest default for ordinary prove-a-Rust-program workloads.
- Claude Smaller ecosystem and rougher developer experience than SP1/RISC Zero — the flexibility is aimed at teams willing to engineer custom extensions, not at practitioners who just want to prove a Rust binary with minimal setup.
- Gemini The customizability introduces integration complexity, leaving developers with a much higher build-and-maintenance overhead than all-in-one monolithic zkVMs.
