OpenAI has officially launched the GPT-5.6 family with Sol, Terra, and Luna, and after extensively testing every model, it's safe to say OpenAI is back in a big way.
OpenAI today released new conversational models, called GPT-Live-1 and GPT-Live-1 mini, claiming that they sound more natural and can handle turn-taking better. These are full-duplex models, meaning they can speak and listen at the same time, allowing users to interrupt naturally and enabling features like live translation.
On Tuesday, OpenAI released a new foundation model called GPT-5.5 Instant, which will replace GPT-5.3 Instant as the default ChatGPT model. The company said the model reduces hallucination in sensitive areas such as law, medicine, and finance, while maintaining the low latency of its predecessor.
OpenAI just open-sourced Symphony, their internal orchestration spec for scaling autonomous coding agents, and it highlights one of the biggest shifts happening in AI engineering right now. As coding agents become more capable, humans become the bottleneck, and the real work moves from writing code to building the scaffolding around the agents.
In this video, I break down the mental models behind agent harness engineering and show you how to think about building reliable autonomous systems at scale. Whether you're trying to scale Claude Code beyond a few chat sessions, or designing orchestration into your own AI powered apps, these frameworks will help you architect systems that actually work in production.
On Thursday, OpenAI released GPT-5.5 and GPT-5.5 Pro. The new model is, unsurprisingly, its most capable model yet.
After Anthropic launched Opus 4.7 a week ago, it was only a matter of time before OpenAI would follow suit — and, at least according to the benchmarks we’ve seen so far, GPT-5.5 and 5.5 Pro beat Opus 4.7 across many of today’s standard benchmarks. In many benchmarks, though, GPT-5.4 Pro still outperforms the default GPT-5.5.
Three of the biggest players in AI all made moves in the agent space over the last seven days. Anthropic launched Claude Managed Agents, a fully cloud-hosted agent platform. The very next day, LangChain responded with Deep Agents Deploy, explicitly positioned as the open alternative. And then OpenAI shipped the next evolution of the Agents SDK.
The problem is none of these announcements make sense in isolation. Each one is solving a different version of the same problem, at a different point on the build-to-buy spectrum.
On Thursday, OpenAI released GPT-5.4, a new foundation model billed as “our most capable and efficient frontier model for professional work.” In addition to the standard version, GPT-5.4 is also available as a reasoning model (GPT-5.4 Thinking) or optimized for high performance (GPT-5.4 Pro).
The API version of the model will be available with context windows as large as 1 million tokens, by far the largest context window available from OpenAI.
OpenAI on Thursday launched GPT-5.3-Codex-Spark, a stripped-down coding model engineered for near-instantaneous response times, marking the company's first significant inference partnership outside its traditional Nvidia-dominated infrastructure. The model runs on hardware from Cerebras Systems, a Sunnyvale-based chipmaker whose wafer-scale processors specialize in low-latency AI workloads.
GPT-5.3 Codex is blowing minds in early 2026! In this video, we put OpenAI’s fastest, most interactive coding AI to the test and compare it against Claude Opus 4.6—one of the deepest reasoning, long-horizon planning models out there.
OpenAI on Wednesday released GPT-5.3-Codex, which the company calls its most capable coding agent to date, in an announcement timed to land at the exact same moment Anthropic unveiled its own flagship model upgrade, Claude Opus 4.6. The synchronized launches mark the opening salvo in what industry observers are calling the AI coding wars — a high-stakes battle to capture the enterprise software development market.
Explore the OpenAI Codex app, a potential command center for AI agents. This video demonstrates the app's features, including multi-project handling and built-in voice dictation. A firsthand setup and usage walkthrough on macOS is also included.
ServiceNow announced a multi-year partnership with OpenAI to bring GPT-5.2 into its AI Control Tower and Xanadu platform, reinforcing ServiceNow’s strategy to focus on enterprise workflows, guardrails, and orchestration rather than building frontier models itself.
In this video, I look at the Open Responses Standard that's been released by OpenAI to support open models with their Responses SDK.
The rumors were true: OpenAI on Thursday announced the release of its new frontier large language model (LLM) family, GPT-5.2.
OpenAI describes GPT-5.2 as its "most capable model series yet for professional knowledge work," aiming to reclaim the performance crown with significant gains in reasoning, coding, and agentic workflows.
Aardvark, OpenAI's new agentic security researcher powered by GPT-5 and released Thursday, can assist security teams by identifying and helping patch vulnerabilities. The agent is meant to tackle existing challenges in the software security space, as tens of thousands of new vulnerabilities are discovered across enterprise and open-source codebases every year.
Today, OpenAI launched its new Atlas web browser in a surprise livestream. OpenAI’s browser project has been an open secret in Silicon Valley since at least this summer — and it was clear from the beginning that it would be a potential threat to Google, current owner of the world’s most popular browser. But Tuesday’s product and presentation details made it clear exactly how much the web giant has to lose in the AI era — and how little the Google’s success with Gemini seems to have helped.
AI agents, as of now, don’t have the ability or the trust infrastructure to make people and banking institutions feel safe enough to let it loose on someone’s cash. And so, over the past few weeks, three competing agentic commerce standards have emerged: Google announced the Agent Pay Protocol (AP2) with partners including PayPal, American Express, Mastercard, Salesforce and ServiceNow. Soon after, OpenAI and Stripe debuted the Agentic Commerce Protocol (ACP), and just this week, Visa launched the Trusted Agent Protocol (TAP).
OpenAI just changed everything. ChatGPT Apps are here — full-blown apps that run inside ChatGPT itself. Think of it as an entirely new ecosystem with visual widgets, agent builders, and even its own upcoming ChatGPT App Store.
