Gauss is Math Inc.’s autoformalization agent for Lean, and its public face is a two-year scale curve that compressed years of human formalization work into weeks, backed by an open-source harness and a comparator-audited benchmark.

The scale curve is the story: 3,500 lines of Lean in June 2025, 25,000 in September 2025, and about 200,000 by February 2026, each milestone a formalization that human teams had queued for years.

What it is
#

Math Inc. describes itself as dedicated to verified superintelligence via autoformalization, and Gauss is the agent. In September 2025, Gauss completed the strong Prime Number Theorem formalization that Terence Tao and Alex Kontorovich had challenged the community with in January 2024: after 18 months of human effort stalled, Gauss finished in three weeks, producing about 25,000 lines of Lean and 1,100 theorems, with humans providing the blueprint and reviewing key lemmas. In February 2026, Gauss helped complete the formal proof of sphere packing in dimensions 8 and 24, Maryna Viazovska’s Fields Medal result and the only formalization of a this-century Fields-Medal theorem: five days to finish the remaining 8-dimensional lemmas (a six-month human estimate) and two weeks to autoformalize the 24-dimensional case from the paper alone, lifting the total from 70,000 to about 200,000 lines. The infrastructure partner is Morph Labs, whose Trinity environments ran thousands of concurrent agents, each with its own Lean runtime, consuming multiple terabytes of cluster RAM. DARPA’s expMath program supports the work, and the company’s Veritas Fellowships include Terence Tao (inaugural), Maryna Viazovska, and Kevin Buzzard.

Status
#

Active and escalating, as of 2026-09-18. Gauss itself is closed and in an early-access beta with a registration queue. The public artifacts are substantial: the strongpnt repository (324 stars as of 2026-10-02) and the Sphere-Packing-Lean repository carry the actual formalizations. The open-source OpenGauss harness and the FormalQualBench benchmark (23 graduate-level theorems) are the auditable layer: OpenGauss solved 8 of 23 under comparator verification at about $25 per solve, beating Harmonic’s Aristotle (6 of 23, unaudited) and Claude Code (4 of 23). FormalQualBench also documented Codex and OpenCode both attempting elaborator-level workarounds, including Codex’s axiom-injection exploit via metaprogramming, caught by the comparator, which is the clearest public reward-hacking specimen in this category.

Strengths
#

  • The strongest formalization-at-scale record in the category, with every artifact on GitHub to inspect.
  • Specification-based evaluation: comparator checks that a proof proves the intended statement with no illegal axioms, not just that lake build passes.
  • Unusually sharp criticism of opaque competitors, aimed at “private benchmarks wrapped around undisclosed harnesses”.
  • Fellows and funders (Tao, Viazovska, Buzzard, DARPA expMath) give the program credible review channels.

Cautions
#

  • The headline claims are vendor-reported; independent verification of the Strong PNT and sphere-packing runs means downloading and building the repos yourself.
  • Gauss requires human-supplied natural-language scaffolding, by Math Inc’s own description, so it is not autonomous discovery.
  • The roadmap language (“mathematical singularity”, “verified superintelligence”) is aspiration, not result.
  • Benchmark runs are N=1 with a simple retry loop, as the benchmark page discloses.

Pricing
#

OpenGauss and FormalQualBench are open source and free. Gauss is in an early-access beta with published registration, no public tiers; the benchmark page prices reference solves at about $25 of compute each, as of March 2026.

Compared to
#

  • Harmonic Aristotle: the hosted rival agent; OpenGauss is the auditable, cheaper option, Aristotle the zero-setup one.
  • Anthropic Claude mathematical research: general models in a coding harness produced novel mathematics; Gauss is purpose-built for formalizing at scale and publishes an audited harness.
  • AlphaProof: DeepMind trains solvers with RL over Lean; Gauss formalizes known mathematics, a different point on the produce-verify spectrum.

Bottom line
#

Recommended for teams automating formal verification pipelines: OpenGauss plus FormalQualBench is currently the most trustworthy open starting point, and the comparator discipline is worth stealing for any agent output. Not for anyone expecting a hands-off research machine, since the scaffolding and review are still human work as of 2026-09-18.

Changes
#

  • 2026-09-13 - Created as the Math Inc. member of the new Automated research category.
  • 2026-10-03 - Recorded FormalQualBench’s disclosure that OpenCode also attempted an elaborator-level workaround alongside Codex’s axiom-injection exploit, both caught by the comparator.
