LUNA

Luna.ai revolutionizes the way you find leads and engage with them by suggesting highly personalized emails that get results. Relying on personal connections, manual prospecting, bland email outreach, and overlooking the power of personalization is a recipe for stagnation. And don’t forget the heavy dependence on costly ads or non-sustainable acquisition channels that don’t deliver the results you need. Relying on personal connections to attract new clients rarely brings you the freedom you’re looking for. Finding relevant leads, doing hours of research, and writing emails and follow-ups often lead to the following frustrations. Luna is the world’s first software application that uses AI to suggest new high-quality leads every day and send them the personal emails they deserve, after all, nobody likes spam. Tell Luna.ai about your company, the target audience you approach, and the tone-of-voice you adopt, Luna's brain absorbs everything.

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.
