CPM Calculator

AI marketing

CPM Calculator is a free online CPM calculator that instantly calculates CPM (cost per thousand impressions), ad spend, or impressions. Users only need to enter two known values, and the page automatically updates the result without clicking a calculate button. This tool is aimed at YouTube advertising, paid social, brand awareness campaigns, and top-of-funnel media planning scenarios, offering formula display, step-by-step summaries, budget checkpoints, and shareable links. The page also includes industry average CPM benchmarks, market CPM patterns, and a dual-scenario comparison feature to help users evaluate the impact of different CPM assumptions on spend before locking in a budget. All calculations and benchmark data are directional references and must be validated against specific channels, targeting, inventory quality, and buying models.

CPPO

AI developer platforms

CPPO (Completion Pruning Policy Optimization) is a method for accelerating the training of reasoning models based on GRPO (Group Relative Policy Optimization). The project was released by lzhxmu on GitHub, and the paper has been accepted by NeurIPS 2025. Although GRPO is effective, it requires sampling multiple completions for each question, resulting in high training costs. CPPO significantly reduces the number of completions required for gradient computation and updates by pruning completions with lower absolute advantage, and introduces a dynamic completion allocation strategy that maximizes GPU utilization by incorporating additional questions. Experimental results show that, compared with the original GRPO, CPPO can achieve up to 8.32x speedup on GSM8K and 3.51x speedup on Math, while maintaining or even improving accuracy. The project provides a verl version and has open-sourced the relevant repository files.

Crab

AI developer platforms

CRAB (Cross-environment Agent Benchmark) is a general benchmarking framework for multimodal language model agents, developed by the CAMEL-AI team. It provides an end-to-end and easy-to-use framework for building agents, operating environments, and creating benchmarks to evaluate them, and includes three core components: cross-environment support, graph evaluator, and task generation. The CRAB Benchmark-v0 developed based on this framework was released on October 18, 2024, includes 120 tasks in two environments, Ubuntu and Android, and was tested using 6 different multimodal language models under 3 communication settings. CRAB supports seamless adaptation across multiple environments, provides fine-grained performance analysis through the graph evaluator, and uses a graph-based method to automatically generate complex tasks close to real-world scenarios. All agent operations, observations, and evaluators are defined through Python functions. Adding a new environment requires only a small amount of code, and the configuration follows a declarative programming paradigm, making experiments easy to reproduce.
