GPT-5.4 Review: The Computer-Use Frontier
GPT-5.4 brings native computer use, a 1M token context window, and serious coding muscle to OpenAI's mainline model - but at a premium price.

GPT-5.4 brings native computer use, a 1M token context window, and serious coding muscle to OpenAI's mainline model - but at a premium price.

OpenAI posted '5.4 sooner than you Think.' one hour after launching GPT-5.3 Instant. Here is what the Codex repo leaks already told us - and what the tweet does not.

Google quietly launched Gemini 3.1 Flash-Lite Preview - the first Flash-Lite in the Gemini 3 series - while announcing Gemini 3 Pro will shut down March 9. Developers have six days to migrate.

OpenAI ships GPT-5.3 Instant with 27% fewer hallucinations, a less preachy tone, and better web search - available now across all ChatGPT tiers and the API.

Two pull requests in OpenAI's public Codex GitHub repo referenced GPT-5.4 before being scrubbed - one adding full-resolution vision support, the other a fast mode toggle. Seven force pushes and a deleted employee screenshot confirm this was not intentional.

Google's Gemini 3.1 Pro more than doubles its predecessor's reasoning scores and introduces adjustable thinking modes, but latency issues and preview-status quirks keep it from a clean sweep.
