OpenAI says GPT-5.4 Thinking and Pro are rolling out gradually across ChatGPT, the API, and Codex. The company positions GPT-5.4 as a unified frontier model for professional work with stronger coding, tool use, and 1M-token context.
Google DeepMind said Gemini 3.1 Flash-Lite is rolling out in preview through the Gemini API and Google AI Studio. The company positioned it as the most cost-efficient Gemini 3 model, with lower price, faster performance, and tunable thinking levels.
OpenAI says GPT-5.4 Thinking is shipping in ChatGPT, with GPT-5.4 also live in the API and Codex and GPT-5.4 Pro available for harder tasks. The launch packages reasoning, coding, and native computer use into a single professional-work model with up to 1M tokens of context.
OpenAI Developers has updated its GPT-5.4 API prompting guide. The new guidance focuses on tool use, structured outputs, verification loops, and long-running workflows for production-grade agents.
Google AI shared practical Gemini 3.1 Flash-Lite examples, including high-volume image sorting and business automation scenarios. The thread also points developers to preview access via Gemini API, Google AI Studio, and Vertex AI.
OpenAI announced that GPT-5.4 Thinking and GPT-5.4 Pro are rolling out in ChatGPT, while GPT-5.4 is already available in the API and Codex. The launch positions GPT-5.4 as a unified frontier model for reasoning, coding, and agentic workflows.
Google AI Developers announced that Gemini 3.1 Flash-Lite is rolling out in preview via the Gemini API and Google AI Studio. The post positions it as the fastest and most cost-efficient model in the Gemini 3 line, now adding dynamic thinking for task-adaptive reasoning.
OpenAI released GPT-5.3 Instant on March 3, 2026 as a faster, cheaper derivative of GPT-5.3 for day-to-day use. The company says it matches GPT-4.1 latency and pricing while improving instruction following and reducing hallucinations.
OpenAI announced GPT-5 on 2025-08-07 for both ChatGPT and API usage. The launch highlights include a reported 45% hallucination reduction vs GPT-4o and major benchmark gains such as HealthBench Hard 44.6.
Google announced a major Gemini 3 Deep Think upgrade with stronger reasoning benchmarks and early API access for researchers and enterprises.
