OpenAI just announced that it will retire GPT-4o, GPT-4.1, GPT-4.1 mini, and o4-mini from ChatGPT on February 13, 2026, though API access remains unchanged. The company noted that daily GPT-4o usage has plummeted to just 0.1% as users shifted to newer releases with updated conversational styles.
Anker just launched Soundcore Work, a wearable AI voice recorder roughly the size of a quarter. The $159 clip-on gadget packs an 8-hour battery, transcribes over 100 languages with speaker separation, and uses GPT-4.1 to summarize meetings in one click.
Microsoft just introduced CLIO, a runtime optimization framework that enables base LLMs to self-adapt their reasoning without reinforcement learning post-training. On Humanity's Last Exam biology and medicine questions, it pushed GPT-4.1's accuracy from 8.55% to 22.37%, outperforming OpenAI's o3. Why it matters: scientists get real control knobs to flag uncertainty and correct thought paths mid-stream.
California lawmakers just revived their push to regulate frontier AI with a toned-down bill called SB 53. Introduced by State Senator Scott Wiener, it would mandate leading labs like OpenAI and Google to publish safety protocols and report major incidents, while dropping developer liability rules that killed the previous SB 1047.
OpenAI just notified developers that GPT-4.5 Preview will be removed from its API on July 14, 2025. While the phase-out was technically planned back in April alongside GPT-4.1's debut, the reality check has left teams relying on its creative writing tone scrambling to migrate. ChatGPT subscribers can still breathe easy: it remains an option in the web dropdown.
OpenAI just teamed up with Kaggle to launch the OpenAI to Z Challenge, inviting developers to hunt for hidden Amazon archaeological sites using o3/o4 mini and GPT-4.1. Participants must combine open satellite imagery and lidar scans to uncover lost settlements, competing for a $250,000 first prize.
OpenAI just rolled out its GPT-4.1 and GPT-4.1 mini models directly into ChatGPT. The new models pack stronger coding and instruction-following chops than GPT-4o while running much faster than reasoning models like the o-series. GPT-4.1 is available to Plus, Pro, and Team subscribers, while mini is free for all users as it officially replaces GPT-4o mini.
OpenAI just dropped three new models in its API: GPT-4.1, GPT-4.1 mini, and its first-ever GPT-4.1 nano. They feature a 1-million-token context window, jump to 54.6% on SWE-bench Verified coding, and mini slashes costs by 83% while nearly halving latency. It is built squarely for developers building agents and coding workflows, though it won't be available in ChatGPT directly.
OpenAI just published an official prompting guide for GPT-4.1, detailing how to leverage its literal instruction following. By baking in three core reminders around persistence, tool calling, and deliberate planning, OpenAI boosted its agentic SWE-bench Verified score by nearly 20%.
