Can LLMs Write Correct TLA+ Specifications? Evaluating Natural-Language-to-TLA+ Generation

Researchers conducted the first systematic evaluation of Large Language Models' ability to generate correct TLA+ formal specifications from natural language, testing 30 LLMs across 2,730 runs. Results show LLMs achieve only 8.6% semantic correctness despite 26.6% syntactic correctness, indicating current models cannot reliably produce formal specifications without expert oversight.

TLA-Prover: Verifiable TLA+ Specification Synthesis via Preference-Optimized Low-Rank Adaptation

Researchers have developed TLA-Prover, a 20-billion-parameter AI model that significantly improves the synthesis of TLA+ formal specifications for distributed systems, achieving 30% correctness on verified benchmarks—roughly 3.5x better than previous baselines. The model combines supervised fine-tuning with repair-based policy optimization and uses TLC model checker feedback directly as a reward signal, eliminating the need for learned reward models.

TraceFix: Repairing Agent Coordination Protocols with TLA+ Counterexamples

TraceFix is a verification-first framework that uses TLA+ model checking to automatically repair and validate multi-agent LLM coordination protocols, achieving 100% verification success on 48 test tasks with 62.5% passing on first attempt. The approach reduces deadlock/livelock failures from 31.1% to 14.1% and improves task completion rates to 89.4% compared to unverified baselines.
