Positioning brief — for the RISC Zero team
Why the models put RISC Zero at #2 for zkvm for verifiable offchain compute
- mature, battle-tested production choice GPT · Claude · Gemini · Grok“The most battle-tested general-purpose choice”
- strong Rust developer workflow GPT · Claude · Gemini · Grok“excellent Rust developer experience”
- audited correctness and formal verification GPT · Claude · Grok“multiple third-party audits, a formally specified RISC-V circuit”
- scalable proving and broad integrations GPT · Claude · Gemini · Grok“broad ecosystem integrations (multi-chain verification, oracles, coprocessors)”
What the models credit SP1 (#1) with — and don’t credit RISC Zero
- leading raw proving throughput GPT · Claude · Gemini · Grok“Leading performance (often fastest in benchmarks”
- near-real-time Ethereum block proving Claude · Grok“SP1 Hypercube's demonstrated near-real-time Ethereum block proving”
- lower EVM verification costs Gemini“Outperforms competitors in raw proving speed and EVM verification costs”
What would move the rank — the models’ fix lines, unified
- improve proving speed and latency GPT · Claude · Gemini · Grok“Slightly trails SP1 in peak speed/latency for heaviest workloads”
- reduce proving overhead and costs GPT · Claude · Gemini · Grok“Generally slower and costlier per cycle than SP1 on compute-heavy workloads”

The most battle-tested general-purpose choice, with a mature Rust workflow, strong documentation, explicit privacy semantics, recursive receipts, transparent STARK foundations, independent audits, Bonsai proving, and substantial real-world integration evidence.
Claude The most battle-tested zkVM — longest production history, multiple third-party audits, a formally specified RISC-V circuit, mature dev tooling (Bonsai, Steel for EVM state proofs), and the Boundless proving marketplace for offchain capacity; R0VM 2.0 closed much of the raw speed gap. Best pick when correctness assurance and ecosystem maturity outweigh peak benchmark numbers; near-tie with SP1, ranked second mainly on raw prover throughput.
Gemini Offers the most mature, battle-tested codebase, stable RISC-V implementation, and comprehensive SDK, backed by the Boundless decentralized prover market to easily scale variable proving workloads.
Grok Production-ready since 1.0/earlier with Bonsai cloud (reliable 1M+ cycles/sec throughput), excellent Rust developer experience, broad ecosystem integrations (multi-chain verification, oracles, coprocessors), consistent benchmarks, formal verification progress, and open-source maturity; strong real-world value for typical practitioners seeking dependable offchain verifiable compute.
Where RISC Zero falls short, per the models
- GPT Proving is commonly slower or more resource-intensive than SP1 and newer performance-focused systems.
- Claude Generally slower and costlier per cycle than SP1 on compute-heavy workloads, so at large scale the proving bill is the trade-off for its conservatism.
- Gemini Higher base proving overhead and slower local CPU proving times than SP1, making it unsuitable for latency-sensitive applications unless developers strictly optimize trace-level code or pay market premiums for outsourced proving.
- Grok Slightly trails SP1 in peak speed/latency for heaviest workloads; higher costs without heavy optimization.
The most mature general-purpose zkVM — stable Rust toolchain, strong tooling and docs, the Bonsai/managed proving path, and proven deployments; a safe zkVM choice for teams that value stability over raw benchmark leadership.
Where RISC Zero falls short, per the models
- Claude Proving latency and cost remain the main tax, and like any zkVM it is overkill when you need a small, cheap-to-verify circuit rather than general computation. Near-tie with SP1 — SP1 edges it on prover performance/precompiles, RISC Zero on maturity.
