About ACG Tools

ACG Tools provides a collection of six free utilities tailored for developers who build and run AI coding agents, with a primary focus on tracking and forecasting token expenses. The suite operates using official model price lists rather than live API calls, allowing users to estimate costs before deployment and mitigate the risk of unexpected expenses. Core tools include calculators for official large language model (LLM) list prices, GPT-6 Astra API costs, monthly agent burn rates, and prompt-level billing, enabling precise cost projections at different stages of development. Additional resources include budget-aware MCP templates designed for coding agents, a checklist of twelve cost runaway signals to identify potential budget overruns, and detailed explanatory pages that compare pricing models such as Batch versus Flex, ChatGPT subscriptions versus API billing, and Astra versus Sol rates. The tools are particularly suited for teams aiming to implement basic budget controls and cost predictability without the need to integrate a full monitoring service. By leveraging official pricing data, ACG Tools empowers agent builders to make informed decisions about model selection, deployment strategies, and cost optimization before scaling their projects.
