GPT-5.2 Codex, o3 and GPT-4.1 are reshaping AI

AI news is moving so fast that one week can bring new coders, new APIs, and new safety bets. Here are the latest drops worth watching today ^[1]^[2]^[4].

🧵 1/5

GPT-5.2 Codex just showed up in the latest AI release roundup, putting coding-focused model updates back in the spotlight. If coding assistants keep improving this fast, how much of dev work stays manual? ^[2]

🧵 2/5

OpenAI’s news page now lists Introducing OpenAI o3 and o4-mini, both released on Apr 16, 2025. That signals another push in reasoning models, with the smaller o4-mini likely aimed at faster, lighter use cases ^[4].

🧵 3/5

GPT-4.1 in the API is also on OpenAI’s April 2025 news list, alongside 4o Image Generation and next-generation audio models. The pattern is clear: one company, multiple modalities, all moving at once ^[4].

🧵 4/5

New models are arriving so quickly that llm-stats now tracks 240+ releases across 500+ models and highlights trends like reasoning, multimodal, and efficiency gains. Which change do you think will matter most next ^[1]^[2]?

Reply below!”). * Keep it concise and avoid hashtags. Additional notes: * Assume access to up-to-date data; for each item, fetch or insert the date/source before writing. * Ensure each tweet clearly states the most important thing about its news item. * Avoid hashtags altogether.Write a Twitter thread (X thread) about the very latest AI news, formatted as follows: 1. **First tweet (hook):** * Spark curiosity with a provocative question or surprising statement about AI today. * Tease that you'll share several must-know developments in the thread. * Keep it ≤280 characters and avoid hashtags. 2. **Subsequent tweets (one per news item):** For each: * **Headline/Context (concise):** A short phrase identifying the development (e.g., “Major breakthrough in multimodal models”). * **Key insight:** State the single most important takeaway or implication (“It can now generate lifelike videos from text prompts, potentially transforming content creation.”). * **Why it matters / curiosity angle:** A brief note on impact or a rhetorical question that encourages engagement (“Could this replace human editors?”). * **Brevity:** Stay within 280 characters total. * **Tone:** Informational yet conversational and shareable—use an emoji or casual phrasin AI’s latest moves: Codex, prices, and benchmarks AI’s latest shifts: models, trust, code, and video
