OpenAI has begun a limited preview of the GPT‑5.6 family: **Sol** (flagship), **Terra** (balanced, 2× cheaper than GPT‑5.5), and **Luna** (fast, low‑cost). Sol introduces a new “max” reasoning mode and an “ultra” mode that uses sub‑agents. Early benchmarks show state‑of‑the‑art performance on coding (Terminal‑Bench 2.1), biology (GeneBench v1), and cybersecurity (ExploitBench, ExploitGym). The models ship with OpenAI’s most robust safety stack to date, but the preview may block or delay some requests.
OpenAI: OpenAI announced a limited preview of the GPT‑5.6 family—Sol, Terra and Luna. Sol is the new flagship, described as a step‑function improvement over GPT‑5.5. Terra delivers performance competitive with GPT‑5.5 at roughly 2× lower cost, and Luna is the most cost‑efficient model, offering strong capability at the lowest price. The company plans to make the three models generally available in the coming weeks, but the preview is currently limited to a small group of trusted partners in Codex and the API at the request of the U.S. government.
Google DeepMind announces Gemini 3.5 Flash now includes a native computer‑use tool, enabling developers to create agents that can see and act across browsers, mobile and desktop interfaces.

Visual Studio Code’s latest release adds a unified model customization picker for tuning and shows total chat‑session costs, simplifying cost tracking and usage insight.
Kimi.ai: Released the open‑source Kimi‑K2.7‑Code model, reporting +21.8% on Kimi Code Bench v2, +11.0% on Program Bench, +31.5% on MLS Bench Lite, and 30% lower reasoning overthinking. Google Research: Launched Gemini‑SQL2, a text‑to‑SQL system built on Gemini 3.1 Pro that hits state‑of‑the‑art scores on the BIRD benchmark. OpenAI: Added saved Codex rate‑limit resets for Go, Plus, Pro, and Business tiers (one free reset) and a two‑week invite program letting Plus/Pro users earn extra resets by inviting friends. Claude: Made dynamic workflows in Claude Code generally available, letting the model orchestrate parallel sub‑agents for complex tasks like codebase‑wide bug hunts and verify work before returning results.
NVIDIA AI announced the release of Nemotron 3 Ultra, a 550 B MoE model that speeds inference fivefold, lowers agentic task costs up to 30 % and excels at coding, deep research, and long‑horizon planning. OpenCode noted that Nemotron 3 Ultra is now free with 1 M context and fully open source. Ollama said the model is available on its cloud platform, offering launch commands for Claude, Hermes and OpenClaw. OpenAI introduced a new memory system for ChatGPT that automatically tracks important details, doubles memory capacity for Plus and Pro users in the US, and lets users review and steer remembered content via a summary. Cursor added an interactive context‑usage report in its canvas, breaking down token distribution across prompts, tools, rules and skills.
Qwen: introduces Qwen3.7-Plus, a multimodal agent model that unifies vision and language with both GUI and CLI operation and serves as a coding and productivity assistant. OpenAI: frontier models and Codex are now generally available on AWS via Amazon Bedrock, extending enterprise security, compliance, and governance workflows. xAI: Composer 2.5 is now inside Grok Build, described as a fast, highly intelligent model for long‑running tasks and complex instructions. LangChain: highlights Fleet for secure agent access to private resources and adds LangSmith LLM Gateway spend limits that return a 402 error when caps are hit. Google Antigravity: is becoming a scientific workbench with a Science Skills bundle that runs complex workflows like protein analysis using Alpha* models and dozens of databases; Google Gemma: releases the first gemma‑skills iteration, enabling agents to build with Gemma, use MTP for speed, pick model size, and locate up‑to‑date resources. ClaudeDevs: resets 5‑hour and weekly rate limits for Pro/Max plans and fixes excessive parallel subagents; Cursor: raises usage limits for Teams and adds a Premium seat with 5× usage at 3× cost; Visual Studio Code: demos orchestrating agents via the VS Code Agents window; NVIDIA: adds real‑time AI media tools including Synthetic Video Detector (up to 92% accuracy, 22 ms latency), RTX Video Super Resolution and Frame Generation; Vercel: enables remote execution of Conductor’s parallel coding agents on fast Sandboxes; Perplexity: launches Search as Code, a new architecture that writes Python to call its search stack directly, now default in the Perplexity Agent API.

OpenAI and Thrive Holdings collaborated to build Tax AI, a self-improving tax agent that automates tax preparation and improves over time. The system uses Codex to turn production use into structured signals that fuel autonomous improvement.
OpenRouter now supports "apply_patch," a server tool that lets models propose file edits using V4A diffs through the Responses API. The model generates a patch, and OpenRouter validates the diff syntax server-side. This feature allows for more efficient and accurate file editing. xAI has released grok-build-0.1 in public beta via the xAI API. This model powers the Grok Build CLI and excels at agentic coding, priced at $1/m input and $2/m output. Google AI has released an episode of Release Notes featuring the architects of Gemini, including @JeffDean, @koraykv, @OriolVinyalsML, and @NoamShazeer. They discuss their journey and the people behind the model. LangChain has released LangSmith LLM Gateway, which enforces spend limits and redacts PII before requests reach the model. They also announced Deep Agents v0.6, which makes harness profiles a first-class abstraction, allowing for production-grade performance at lower costs. NVIDIA has announced a new era of PC, but the details are unclear. OpenAI has launched Rosalind Biodefense to help trusted builders develop new biodefense and pandemic preparedness capabilities. They are also expanding trusted access to GPT-Rosalind for select U.S. government and allied partners.
