Reinforcement Learning with Verification

page dédiée →

Training methodology that uses formal verification as reward signal for reinforcement learning, providing much stronger feedback than statistical approaches like RLHF or GRPO. Pioneered by axiom-math as core component of verified-ai systems.

Core Concept

Stronger Reward Signals: Instead of relying on statistical approximations (GRPO, RLHF), verification provides binary correct/incorrect feedback through lean-proofs verification. This is analogous to compiling and testing code rather than guessing correctness.

Training Loop:

  1. Model generates mathematical reasoning or proofs
  2. lean-proofs verifier checks correctness mechanically
  3. Verification result provides immediate, precise reward signal
  4. Model learns from definitive feedback rather than statistical approximations

Advantages

Sample Efficiency: Precise feedback enables faster learning compared to statistical methods that rely on human preferences or approximations.

Maximum Performance: Verification provides objective ceiling for correctness rather than subjective quality assessments.

Compounding Training Data: Verified proofs become high-quality training examples that can be trusted for future training, unlike informal reasoning that may contain subtle errors.

Objective Optimization: Removes human preference biases and statistical noise from training signal.

Technical Implementation

Verification Integration: Uses formal verification engines (like Lean theorem prover) as part of training infrastructure rather than post-hoc validation.

Reward Structure: Binary correct/incorrect signals provide cleaner optimization landscape compared to continuous preference scores.

Curriculum Learning: Can progressively tackle more complex proofs as verification capabilities improve.

Performance Results

axiom-math reports significant advantages using this approach:

  • Perfect 12/12 putnam-mathematical-competition score
  • 99% (187/189) on proofgen-benchmark vs OpenAI o3's 4.9%
  • Superior performance to models trained with statistical methods

Comparison with Statistical Methods

GRPO/RLHF Limitations:

  • Rely on human preferences or statistical approximations
  • Subject to bias and inconsistency
  • Cannot compound knowledge reliably
  • Provide weaker optimization signals

Verification Advantages:

  • Mathematically precise feedback
  • Enables knowledge compounding
  • Objective optimization target
  • Higher sample efficiency

Implementation Challenges

Lean Generation Difficulty: Current LLMs struggle to generate valid lean-proofs directly, requiring specialized training approaches.

Scaling Brilliance

page dédiée →

Core philosophical framework of axiom-math and carina-hong describing how formal-verification enables both scaling and compounding of mathematical insights. The concept has two complementary dimensions that together enable exponential knowledge growth.

Two Dimensions

Scaling Dimension

Definition: Enabling more people to benefit from mathematical insights

  • Formal proofs communicate intuitions reliably across individuals
  • Verified results can be trusted and built upon by others
  • Quality of formal proofs approaches human-level regardless of generating system
  • High-quality training corpus grows through verified outputs

Compounding Dimension (compounding-brilliance)

Definition: Mathematical insights building upon each other over time

  • Verified proofs provide solid foundations for further development
  • Future inference and training can reliably build on proven results
  • Avoids the degradation that occurs with informal, unverified reasoning
  • Creates exponentially growing value from proven mathematical knowledge

Historical Analogy: Ramanujan

Hong uses srinivasa-ramanujan as the paradigmatic example. When G.H. Hardy persuaded Ramanujan to formalize his intuitive mathematical insights:

  1. Personal improvement: Formalization forced articulation of details, opening new lines of thinking
  2. Scaling effect: Others could understand, learn from, and validate his work
  3. Compounding effect: Future mathematicians could build reliably on his proven foundations

Technical Implementation

In AI systems, Scaling Brilliance manifests through:

  • Reinforcement Learning with Verification: Using formal proof correctness as training signal
  • Verified knowledge bases: Accumulating mathematically sound results over time
  • Sample efficiency: Stronger verification signals vs statistical approaches (GRPO, RLHF)
  • Maximum performance: Higher ceiling than informal reasoning approaches

Philosophical Foundation

The concept represents Axiom's core thesis that verification isn't about "fixing lousiness" but about amplifying and preserving brilliance. As Hong states: "Verification to me is about scaling brilliance, compounding brilliance."

This distinguishes their approach from traditional AI safety or correctness concerns, instead positioning verification as a fundamental enabler of intellectual progress.

Specification Business

page dédiée →

The recognition that as formal-verification capabilities improve, the primary bottleneck shifts from proof generation to accurately specifying what needs to be proven. As carina-hong states: "Anything that can be specified can be proven. Humans are bad at specifying everything we want."

Core Challenge

The specification business represents a fundamental limitation in the verified-ai approach:

  • Technical capability: AI systems become increasingly capable of generating formal proofs
  • Human bottleneck: The challenge shifts to humans accurately defining the problem space
  • Specification gap: Difference between what humans think they want proven and what they actually need

Implications for Axiom Math

This challenge has significant implications for axiom-math's business model and technical roadmap:

  • Market opportunity may depend more on specification tools than proof generation
  • Need for human-AI collaboration interfaces for problem definition
  • Potential requirement for domain-specific specification languages or frameworks
  • Business model may shift toward specification consulting rather than pure proof generation

Broader Context

The specification business connects to fundamental questions in AI alignment and requirements engineering:

  • Requirements elicitation: Classical software engineering problem at larger scale
  • AI alignment: Ensuring systems optimize for intended rather than specified objectives
  • Domain expertise: Need for deep understanding of problem domains to specify correctly
  • Iterative refinement: Specification as ongoing process rather than one-time definition

Strategic Response

Recognition of the specification business suggests several potential strategic directions:

  • Development of specification assistance tools and methodologies
  • Focus on domains where specification is clearer (mathematics, formal systems)
  • Human-in-the-loop approaches for specification refinement
  • Collaboration tools for specification development and validation

Specification Problem

page dédiée →

Critical challenge in verified-ai systems where the bottleneck shifts from proof generation to accurately specifying what needs to be proven. As carina-hong of axiom-math puts it: "Anything that can be specified can be proven. Humans are bad at specifying everything we want."

Core Challenge

Human Specification Difficulty: While formal-verification can mechanically check correctness once problems are properly specified, translating real-world requirements into formal specifications remains a fundamental human bottleneck.

Gap Between Intent and Formalization: The challenge lies not in proving correctness, but in capturing the full scope of what "correct" means in formal mathematical language.

Implications for Verified AI

Bottleneck Shift: As AI systems become better at generating lean-proofs, the limiting factor becomes humans' ability to specify requirements with mathematical precision.

New Skills Required: Success in verified-ai may require developing better tools and methodologies for specification rather than just proof generation.

Business Implications: Companies implementing verified AI systems may need to invest heavily in specification expertise alongside verification capabilities.

Relationship to Current AI

Informal vs Formal Gap: Current AI systems work well with informal specifications but struggle when requirements must be formalized for verification.

Human-AI Collaboration: May require new paradigms where humans focus on specification while AI handles proof generation and verification.

Potential Solutions

Specification Tools: Development of better interfaces and languages for capturing human intent in formal specifications.

Iterative Refinement: Approaches where specifications can be refined through interaction with verification systems.

Domain-Specific Languages: Creating specialized specification languages for particular application domains.

See also

Paradigm advocated by axiom-math and carina-hong that positions formal verification as essential for achieving artificial general intelligence. Rather than traditional approaches focused on statistical learning, Verified AI emphasizes mathematically provable correctness as the foundation for scaling AI capabilities.

Core Philosophy

"Scaling Brilliance, Not Fixing Lousiness": Verification isn't about error correction but about compounding and scaling mathematical insights. Uses srinivasa-ramanujan analogy - when convinced to formalize proofs, Ramanujan's capabilities improved AND others could build upon his work.

Compounding Knowledge: Formally verified proofs create solid foundations that enable:

  • Scaling: More people can use and trust the results
  • Compounding: Future work can build upon verified foundations
  • Transfer: Knowledge transfers reliably across domains

AGI Necessity: carina-hong makes unqualified claim: "We do not believe there is any other possible future" for AGI development.

Technical Implementation

Training Approach:

Inference Benefits:

  • Verified outputs have reliability comparable to human-generated proofs
  • Enables AI systems to build upon previous verified work
  • Reduces need for human verification bottlenecks

Cross-Domain Applications

Scientific AI: alex-lupsasca notes verification bottleneck in theoretical physics as AI generates thousands of proofs simultaneously.

Physical Systems: Applied Intuition highlights verification challenges in autonomous systems as models improve.

Critical Systems: Hardware verification, flight control, nuclear power, medical devices require formal correctness guarantees.

Implementation Challenges

Specification Problem: "Anything that can be specified can be proven. Humans are bad at specifying everything we want." - Core challenge of translating real-world requirements into formal specifications.

Generation Difficulty: lean-proofs are "expensive to produce, cheap to verify" - current LLMs struggle with direct Lean generation, requiring specialized training approaches.

Frontier Lab Gap: Current frontier labs reportedly still rely on informal proofs rather than direct Lean generation, creating opportunity for specialized approaches.

Market Positioning

Contrasts with current AI development focused on:

  • Statistical learning without verification
  • Informal reasoning and code generation
  • Scale without formal correctness guarantees
