AI agents for software engineering, scaled at inference time
Agents invest additional compute at test time to reason, explore and verify before producing a fix, rather than relying only on a single forward pass.
Systems aimed at real repository work: locating the relevant code, understanding intent and producing changes that address an issue.
The team publishes measured outcomes, including a reported 62.2% resolve rate on SWE-bench Verified.
Regular engineering notes covering agent architecture, evaluation methodology and lessons learned from building coding systems.

Automated reasoning that makes AI-generated software provably correct
Imandra's reasoning engine builds formal models of programs and autonomous systems, then exhaustively analyzes behavior to surface edge cases that testing and statistical models miss.
CodeLogician translates a codebase into mathematical logic and assembles a MetaModel spanning every file and dependency, giving AI assistants a complete structural context with no learning phase.
Instead of sampling inputs, Imandra decomposes state space into behavioral regions so decisions and boundary conditions are examined exhaustively and reproducibly.
Benchmarks published by Imandra show that augmenting LLMs with formal reasoning through CodeLogician closed a 41-47 percentage point accuracy gap on software-analysis reasoning tasks compared with LLM-only approaches.
