Ithy
Ithy is an advanced AI-powered research and knowledge synthesis platform designed to combine the capabilities of multiple leading artificial intelligence models into a single, unified system that produces comprehensive, high-quality answers. It operates as an “AI aggregator,” meaning it does not rely on a single model but instead queries and integrates responses from multiple large language models, including systems similar to ChatGPT, Gemini, and others, to generate more accurate and nuanced outputs. It transforms user queries into interactive, article-style responses that can include text, charts, videos, and other visual elements, creating a richer and more engaging research experience compared to traditional chat-based tools. It offers different research modes, such as fast analysis for quick answers and deep research for more detailed, multi-perspective insights, allowing users to choose the level of depth and speed they need.

GPT-5.6 Luna
GPT-5.6 Luna is the fast and affordable model in OpenAI’s GPT-5.6 series, built to bring strong capability to users and developers who need practical intelligence with lower overhead. In the new GPT-5.6 naming system, the number identifies the model generation, while Sol, Terra, and Luna identify durable capability tiers that can advance on their own cadence, giving people and developers clearer choices across intelligence, speed, and cost. Luna sits alongside Sol, the flagship model, and Terra, the balanced model for everyday work, as part of a family designed for broader access to next-generation AI. During the limited preview, GPT-5.6 models are initially available through the API and Codex to a select group of trusted partners and organizations, with plans for broader availability in ChatGPT, Codex, and the API. OpenAI developed GPT-5.6 Sol, Terra, and Luna with its most robust safeguards to date, with configurations matched to each model’s capabilities.

ChatGPT Plus
We’ve trained a model called ChatGPT which interacts in a conversational way. The dialogue format makes it possible for ChatGPT to answer followup questions, admit its mistakes, challenge incorrect premises, and reject inappropriate requests. ChatGPT is a sibling model to InstructGPT, which is trained to follow an instruction in a prompt and provide a detailed response.
ChatGPT Plus is a subscription plan for ChatGPT a conversational AI.
ChatGPT Plus costs $20/month, and subscribers will receive a number of benefits:
- General access to ChatGPT, even during peak times
- Faster response times
- GPT-4 access
- ChatGPT plugins
- Web-browsing with ChatGPT
- Priority access to new features and improvements
ChatGPT Plus is available to customers in the United States, and we will begin the process of inviting people from our waitlist over the coming weeks. We plan to expand access and support to additional countries and regions soon.
