Training a state-of-the-art large language model (LLM) like GPT-5 is a massive engineering, logistical, and financial undertaking. Headlines and rumors about how many GPUs were used vary wildly — from a few tens of thousands to several hundreds of thousands — and part of that variance comes from changing hardware generations, efficiency gains in software, […]
Sora 2 is one of the fastest-moving AI products of 2025: a next-generation video + audio generation system from OpenAI that produces short cinematic clips with synchronized audio, multi-shot coherence, improved physics, and a “cameos” system for inserting people into generated scenes. Because Sora 2 is new and evolving rapidly — launched in late September […]
OpenAI DevDay 2025 was a high-velocity developer showcase (held in early October 2025) where OpenAI unveiled a broad slate of products, toolkits, SDKs and model releases designed to move the company from model-provider to platform-operator: apps that run inside ChatGPT, a drag-and-drop agent builder (AgentKit), the general-availability rollout of Codex for developer workflows, and a […]
OpenAI’s GPT-5 Pro landed with a splash: touted as the company’s “smartest and most precise” variant of GPT-5, it promises step-changes in reasoning, coding, and multimodal capability, and it’s already showing top marks on a range of public benchmarks. But “most powerful” depends on how you measure power — raw benchmark scores, real-world usefulness, multimodal […]
Sora 2 is OpenAI’s flagship text-to-video and audio generation system designed to produce short cinematic clips with synchronized dialogue, sound effects, persistent scene state, and markedly improved physical realism. Sora 2 represents OpenAI’s step forward in producing short, controllable videos with synchronized audio (speech and sound effects), improved physical plausibility (motion, momentum, buoyancy), and stronger safety controls compared with earlier text-to-video systems.

GPT-5-Codex is OpenAI’s new, engineering-focused variant of GPT-5, tuned specifically for agentic software engineering inside the Codex product family. It’s designed to take on large real-world engineering workflows: creating full projects from scratch, adding features and tests, debugging, refactors, and performing code reviews while interacting with external tools and test suites. This release represents a […]
September 15, 2025. OpenAI unveiled GPT-5-Codex, a specialized variant of GPT-5 optimized for agentic software engineering inside its Codex product. The company says the model can operate autonomously on large, complex engineering tasks for more than seven hours at a stretch, iterating on implementations, fixing failing tests, and delivering completed work with reduced human intervention. […]
GPT-5 is a family and a unified reasoning system that OpenAI ships in multiple variants for different workloads; gpt-5-chat (often seen as gpt-5-chat-latest) is the chat-tuned, non-reasoning variant that powers quick conversational responses in ChatGPT and is exposed to developers as a distinct API model. They share architecture and training lineage, but they are tuned, […]
Grok 4 — the latest flagship model from xAI — is the hot topic in AI circles this summer. Its debut has reignited the competition between xAI, OpenAI, Google and Anthropic for the “most capable general-purpose model,” and with that race comes the inevitable question for everyday users, developers and businesses: is Grok 4 free? […]
GPT-4o is OpenAI’s high-performance, multimodal successor in the GPT-4 line that is available via the OpenAI API, in ChatGPT for paid tiers, and through cloud partners such as Azure. Because model availability and default settings have changed recently (including a brief replacement with GPT-5 and a user-driven restoration of GPT-4o in ChatGPT), the sensible path […]
