The results reveal a fundamental limitation of LLM-only approaches: despite strong code understanding, they fail to reason exhaustively about program behavior, edge cases, and decision boundaries.Using formally defined ground truth derived from automated state-space decomposition, the benchmark enables precise and reproducible evaluation of reasoning quality. Across all tested models, augmenting LLMs with formal reasoning via CodeLogician closes a 41-47 percentage point accuracy gap compared to LLM-only reasoning. These results show that formal reasoning is not merely an optimization, but a prerequisite for scalable and trustworthy AI-generated software.Learn moreRead the paperEdge Case DetectionControl Flow UnderstandingState Space EstimationCoverage CompletenessDirection AccuracyOutcome PrecisionDecision BoundaryLLM + CodeLogiciananthropic/claude-opus-4.6anthropic/claude-sonnet-4.5google/gemini-3-pro-previewopenai/gpt-5.2x-ai/grok-code-fast-1Cut the noiseEscape the noise with Neurosymbolic AINeurosymbolic AI is superior to purely statistical AI because it combines the creativity and pattern-recognition strengths of LLMs with the rigor and precision of symbolic reasoning. This fusion enables systems that can both generate solutions flexibily and prove their correctness, going beyond guesswork to deliver trustworthy, verifiable results.Augmented ContextComplete understandingCodeLogician™ delivers a complete context for LLMs to rely on. The logical models created by CodeLogician™ map every type, state, relation, function, and behavioral region of your codebase. No learning phase, no gradual understanding: instant access to a fully structured representation of how your entire system works.No credit card requiredStart NowNeurosymbolic AICodeLogician™ helps coding assistants think logicallyCodeLogician™ applies neurosymbolic AI to translate source code into precise mathematical logic, striving to create a formal model of the program's behavior that's functionally equivalent to the original source code. This model can then be analyzed with its reasoning tools to prove deep properties, uncover hidden bugs, and automatically generate rigorous test cases. Projects typically consist of many different files, so CodeLogician™ analyzes their dependencies and constructs a single MetaModel that represents the entire project. AI assistants then use CodeLogician and the MetaModel to:Ask deep questions about behavior of codeGenerate test cases with quantitative metricsPlan changes to the source code and verify their correctnessLearn moreSeamless IntegrationTurbocharge your vibe codingWithout CLWith CLFamous problems with using stats-only AI:Stats-only AI coding:• It's only as good as the data it's been trained on• No logical audit trail or independently-verifiable claims• Very difficult to apply in regulated industriesCodeLogician:•Brings rigorous logical reasoning to software development•Scales beyond trained data•Uses techniques relied upon in highly regulated industriesWithoutCodeLogician™File SystemYour AI Coding AssistantRead-onlyTerminalStats-only AI coding:•It's only as good as the data it's been trained on•No logical audit trail or independently-verifiable claims•Very difficult to apply in regulated industriesRead the press releaseDocsWant to know the details of how CodeLogician works?Learn morePricingAvailable plansSelect a plan that scales with your automated reasoning needs, from building AI agents with reasoning skills to deploying enterprise-grade formal verification.
