Chat01

Chat01 is a web-based platform that provides users with direct access to a wide range of large language models developed by OpenAI, including recent iterations like GPT-5.5, GPT-5.4, and GPT-5.2, as well as older models such as o3 and GPT-4.5. The service is designed as an alternative to the official ChatGPT Pro subscription, offering similar capabilities without the need for a paid monthly plan. Users can select from multiple model variants, each with different strengths: some are optimized for reasoning tasks (e.g., “thinking” variants), while others prioritize speed or general conversation. The interface is straightforward: after selecting a model, the user types a question or prompt into a text box and clicks “Get Answer” to receive a response generated by the chosen model. One of Chat01’s core features is its credit-based access system. New users receive two free daily credits, which can be used to query any of the available models. Each model has a different cost per query, indicated by a number in parentheses (e.g., “gpt-5-5 (1)” means one credit per use, while “gpt-5-5-pro (20)” costs twenty credits). Users can also earn additional credits by inviting friends—ten credits per successful referral—or by purchasing one of several paid plans. The paid plans are tiered, offering more credits per day or month, and are described on a separate pricing page. This system allows casual users to try the service for free while providing heavy users with the option to buy credits for extended usage. The platform differentiates itself from official ChatGPT offerings by removing throttling limits. Whereas OpenAI’s free tier imposes rate limits and usage caps, Chat01 claims to provide uninterrupted access as long as the user has credits available. This makes it suitable for tasks
