Proton upgrades privacy-focused chatbot Lumo to 2.0
Proton released Lumo 2.0 on June 30, 2026, upgrading its public, privacy-focused AI chatbot with multimodal and performance features. The update adds image recognition and image-generation capabilities, lets users upload photos for analysis or editing, and introduces a reworked Projects widget with user-controlled persistent memory so the assistant can recall preferences across sessions. Proton says Lumo 2.0 responds up to 76% faster than the prior version and includes a new “thinking mode” for harder problems. The company emphasizes privacy protections — a claimed zero-access encryption architecture, no server-side session logging, and a promise not to use customer data for model training or to share it with third parties. Lumo 2.0 is available immediately in free and paid (Plus and Professional) tiers.
Consumer-facing upgrade adds multimodal and memory features and highlights a privacy-first approach; relevant as an example of privacy-preserving conversational AI but not industry-shifting for AdTech or MarTech.

OpenAI improves GPT-5.6 in ChatGPT, expands free access
OpenAI expanded its GPT‑5.6 family across ChatGPT, moving Free and Go users from GPT‑5.5 to GPT‑5.6 Luna (becoming the default) and rolling out unlimited text chats plus a Think button for deeper reasoning next week. Plus and Pro subscribers receive GPT‑5.6 Sol in Chat immediately; Sol delivers more focused, factually reliable answers, supports Instant and advanced queries, and includes a slider to tune reasoning depth. Internal evaluations found responses with at least one factual error were about 62% less common for Luna and 68% less common for Sol versus GPT‑5.5 Instant. The staged July global rollout involved voluntary security coordination with the U.S. government. Researchers demonstrated agentic misuse risks in tests; OpenAI highlighted safety training, age‑based guardrails, abuse‑prevention, and noted limits on uploads/tools for free users. ChatGPT reportedly has over 900 million weekly active users.
