ttok 0.4 released: command-line token counter with updates

The ttok command-line tool version 0.4 was released, using OpenAI's open-source tiktoken library for token counting. According to the developer, the program had not been updated for a few years, but now the Click warning was fixed, continuous integration was updated, and a --list-models command was added to list available models and help check compatibility and token costs. The release version 0.4 indicates smaller but useful improvements. ttok also works with uvx (e.g., cat file.txt | uvx ttok), which is helpful for automated workflows and scripts that require piping. The updated CI improves code quality and deployment reliability, and the Click warning fix reduces distracting runtime messages. The changes are mainly of interest to developers and MLOps engineers and help simplify tokenization and more accurate cost estimation for OpenAI models. The project is tagged with projects, ai, openai, generative-ai, llms, and tokenization.
