GPT-5.4 released with tool search, computer use, and frontier benchmark performance
OpenAI released GPT-5.4 in Thinking and Pro variants, featuring an expanded context window (up to 1.05M input tokens), native computer use, tool search capabilities, and adjustable reasoning levels. In independent testing by Artificial Analysis, GPT-5.4 Pro at xhigh reasoning achieved state-of-the-art on GDP-Val-AA, BrowseComp, Terminal-Bench-Hard, SWE-Bench-Pro, and MCP Atlas, while trailing Gemini 3.1 Pro Preview on MMMU-Pro and Humanity's Last Exam. Pricing is set at the top of the market ($30/$180 per million input/output tokens for Pro), and the release also powers Codex, OpenAI's competitor to Claude Code. The item is reported via The Batch (tier 2 commentary) and includes additional context on Andrew Ng's chub CLI tool for agent documentation sharing.
Introducing GPT-5.5
OpenAI has announced GPT-5.5, described as their most capable model to date, with improvements in speed and reasoning targeted at complex tasks including coding, research, and data analysis. The announcement positions GPT-5.5 as a step beyond GPT-5 in OpenAI's model lineage. The blog post is brief and announcement-level, with limited technical detail provided at this stage.
OpenAI GPT-5.4 Pro and GPT-5.4 Thinking challenge Gemini 3.1 Pro Preview for top AI model position
OpenAI released GPT-5.4 in two variants (Pro and Thinking), featuring expanded context windows up to 1.05M tokens, native computer use, tool search capabilities, and adjustable reasoning levels. In independent benchmarks by Artificial Analysis, GPT-5.4 Pro at xhigh reasoning nearly ties Gemini 3.1 Pro Preview on the Intelligence Index (57 vs 57.2 points) but at roughly 3.3x the cost, while leading on coding and agentic sub-indices. The release leapfrogs Claude Opus 4.6 on most benchmarks but faces stiff competition from Google's Gemini 3.1 Pro Preview, which maintains a price and multimodal advantage.
Claude Opus 4.6 Released with 1M Token Context, Agentic Coding Advances, and State-of-the-Art Benchmarks
Anthropic has released Claude Opus 4.6, its most capable model to date, featuring a 1M token context window in beta, improved agentic coding and planning capabilities, and adaptive thinking with developer-controlled effort levels. The model claims top scores on Terminal-Bench 2.0, Humanity's Last Exam, GDPval-AA, and BrowseComp, outperforming OpenAI's GPT-5.2 by 144 Elo points on GDPval-AA. New product features include agent teams in Claude Code, context compaction for long-running tasks, and Claude in PowerPoint (research preview). Pricing remains unchanged at $5/$25 per million input/output tokens.
Claude Opus 4.1 Released with 74.5% SWE-bench Verified Score
Anthropic has released Claude Opus 4.1, an incremental upgrade to Claude Opus 4 focused on agentic tasks, coding, and reasoning. The model achieves 74.5% on SWE-bench Verified (without extended thinking) and shows notable gains in multi-file code refactoring and large-codebase debugging. It is available to paid Claude users, Claude Code, and via API on Anthropic, Amazon Bedrock, and Google Cloud Vertex AI at the same price as Opus 4. Anthropic notes substantially larger model improvements are planned for the coming weeks.
OpenAI releases GPT-5.4 with integrated reasoning, coding, and agentic capabilities in ChatGPT
OpenAI released GPT-5.4, a frontier model that consolidates recent advances in reasoning, coding, and agentic workflows, incorporating the coding capabilities of GPT-5.3-Codex. The ChatGPT deployment introduces a 'Thinking' mode that surfaces an upfront reasoning plan mid-response, allowing users to redirect the model before it completes. Additional improvements include enhanced deep web research for specific queries, better long-context retention during extended thinking, and improved context window management for faster, higher-quality outputs.
Introducing GPT-5
OpenAI has released GPT-5, described as its most capable AI system to date. The model claims state-of-the-art performance across a broad range of domains including coding, mathematics, writing, health, and visual perception. The announcement positions GPT-5 as a significant intelligence leap over all prior OpenAI models.
OpenAI releases GPT-5.3-Codex, upgraded agentic coding model with faster inference and real-time steering
OpenAI released GPT-5.3-Codex, an incremental upgrade to GPT-5.2-Codex targeting complex software engineering tasks. The new model runs 25% faster, improves reasoning and professional knowledge, and adds better real-time collaboration features including progress updates and in-session steering. It is available immediately across ChatGPT paid plans via the Codex app, CLI, IDE extension, and Codex Cloud, with API access forthcoming.
