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.
GLM‑5.2 is Z.ai’s newest open‑source model designed for long‑horizon coding tasks. It supports a solid 1 million‑token context, introduces flexible “effort” levels for balancing speed and capability, and uses the IndexShare architecture to cut per‑token FLOPs by 2.9×. Benchmarks show it outperforms its predecessor (GLM‑5.1) and ranks as the strongest open‑source coding model, closing the gap to leading closed‑source systems.
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.
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.
