Abstract

A presentation exploring the use of large language models for generating and verifying TLA+ formal specifications. The talk examines how LLMs can assist in the synthesis of formal specifications from natural language, discussing both the promise and the limitations of current models on rigorous specification tasks.

This work builds on the group’s systematic evaluation of LLMs on TLA+ specification synthesis, extending the discussion to practical generation and verification pipelines.

Based On

This presentation builds on the published ICSOFT 2026 paper. The archival record uses the title ChatTLA+ - Can LLMs Write Correct TLA+ Specifications?.
