Mirage, the company behind the video‑editing app Captions, has raised $75 million in growth financing from General Catalyst’s Customer Value Fund. The startup rebranded to Mirage, introduced a freemium model, and launched new AI models for pacing, framing, attention dynamics, and accent‑preserving audio. With more than 3.2 million downloads and over 200 million videos created, the platform serves an international audience and is targeting small‑business marketers. The fresh capital will fuel growth, especially in high‑growth Asian markets, and support the development of additional AI models for video assembly. Read more →

ChatGPT now displays only three model options—Instant, Thinking, and Pro—while the actual AI engine is chosen automatically based on prompt complexity and other factors. The older model names have been removed from the main interface and are only accessible through hidden settings. This shift aims to streamline the user experience and reduce costs, but it also means users may not know which model generated a given answer, creating potential gaps between expectation and reality.

OpenAI has launched two new lightweight models, GPT-5.4 mini and GPT-5.4 nano, described as its most capable small models yet. The models are accessible to free and Go-tier ChatGPT users through a new “Thinking” option rather than a direct model selector. In testing, the Thinking models produced more detailed, multi‑step answers than the standard ChatGPT response, offering clearer reasoning for travel planning and online‑income strategies. While slightly less deep than the full‑size GPT-5.4 Thinking model available to Plus users, the mini and nano versions are faster and provide a notable upgrade for free users. Read more →

OpenAI has launched two smaller versions of its latest GPT-5.4 model—Mini and Nano—designed for developers who prioritize speed and cost over maximum reasoning power. The Mini model runs more than twice as fast as the full model while staying close on key benchmarks, and the Nano model focuses on simple classification and data‑extraction tasks. Both models support text and image inputs, tool use, function calling, and a 400,000‑token context window, and they are available today via the API, Codex, and ChatGPT. This tiered approach lets developers allocate cheaper models for routine work and reserve the full model for complex reasoning, reshaping how real‑time AI applications are built. Read more →

OpenAI has launched GPT-5.4 mini and nano, the smallest and quickest variants of its GPT-5.4 family. Designed as workhorse models for coding and data‑processing tasks, the mini model is reported to be more than twice as fast as its predecessor on coding, reasoning, and tool‑use benchmarks, while still approaching the performance of the full GPT-5.4. The nano model targets even lighter workloads such as classification and data extraction. Both models are available through OpenAI’s API, with the mini model also integrated into Codex and the ChatGPT "Thinking" feature, positioning OpenAI against rivals like Anthropic’s Claude Code.

OpenAI has entered a partnership with Amazon Web Services to deliver its artificial‑intelligence products to U.S. government agencies. The deal leverages AWS’s GovCloud and Classified Regions, allowing OpenAI models to be used for both classified and unclassified workloads. While AWS will distribute the technology, OpenAI retains control over which models are offered and can impose additional safeguards for sensitive deployments. The arrangement builds on OpenAI’s recent Pentagon contract and positions the company to serve a broader range of federal customers through Amazon’s existing cloud infrastructure. Read more →
