MiniMax M2.7 proprietary reasoning model competes with Gemini and Claude Opus; roundup covers Cursor Composer 2, MAI-Image-2, Claude Code Channels, and Anthropic defense dispute
MiniMax released M2.7, a proprietary reasoning model that achieved 66.6% on MLE Bench Lite (tying Gemini 3.1) and 56.22% on SWE-Pro, priced at $0.30/$1.20 per million tokens, with the shift to proprietary marking a potential strategic pivot among Chinese AI labs away from open weights. Cursor released Composer 2, an agentic coding model built on a fine-tuned Kimi 2.5 (via Moonshot partnership), priced 86% cheaper than its predecessor and scoring 73.7 on SWE-bench Multilingual. Anthropic released Claude Code Channels, routing Telegram and Discord messages into local Claude Code sessions via MCP plugins, and separately filed a court response denying it has any backdoor or kill switch into military deployments of Claude. Microsoft announced MAI-Image-2, a text-to-image model ranking third on Arena.ai among research labs.

Cursor's Composer 2.5 rivals GPT-5.5 and Claude Opus 4.7 on coding benchmarks at lower cost
Cursor released Composer 2.5, a specialized agentic coding model built on Moonshot's Kimi K2.5 open weights with additional pretraining and reinforcement learning fine-tuning tailored to Cursor's own CLI harness. The model ranks third on the Artificial Analysis Coding Agent Index behind Claude Opus 4.7 and GPT-5.5 at max reasoning, but significantly undercuts them on cost ($0.44 vs $4.14 per task) and speed (6.7 vs 17.7 minutes). The training approach—co-optimizing model and harness together using synthetic tasks, text feedback during RL, and 25x more synthetic data than Composer 2—illustrates a specialist model strategy that challenges the dominance of generalist frontier models in coding workflows.
Data Points: GLM-5.2 leads open models on coding benchmarks; SpaceX acquires Cursor; OpenRouter Fusion; Anthropic coding study; ChatGPT market share drops
Zhipu released GLM-5.2, a 744B-parameter open model under MIT license that ranks second only to Claude Opus 4.8 on long-horizon coding benchmarks including FrontierSWE and SWE-Marathon, featuring a 1M-token context window and a 2.9× compute reduction via IndexShare attention. SpaceX is acquiring Cursor (Anysphere) for $60B in stock, positioning Musk's company to compete in AI software tools using xAI's Colossus infrastructure. OpenRouter launched Fusion, a multi-model synthesis tool showing that budget model panels can match frontier model performance at half the cost. An Anthropic study of 400K Claude Code sessions found domain expertise—not coding skill—is the primary driver of agentic output, while a Munich court ruled Google liable for false claims in AI Overviews.
Claude 3.7 Sonnet and Claude Code: Anthropic's First Hybrid Reasoning Model and Agentic Coding Tool
Anthropic has released Claude 3.7 Sonnet, described as their most capable model to date and the first hybrid reasoning model on the market, capable of operating in both standard and extended thinking modes within a single unified model. The model achieves state-of-the-art results on SWE-bench Verified and TAU-bench, with particular strength in coding and front-end web development. Alongside the model, Anthropic is launching Claude Code in limited research preview, a command-line agentic coding tool that can read/edit files, run tests, and push to GitHub. Pricing remains unchanged at $3/M input and $15/M output tokens, with availability across Claude.ai plans, Amazon Bedrock, and Google Cloud Vertex AI.
Anthropic Releases Claude Opus 4.5 with State-of-the-Art Coding, Agent, and Computer Use Capabilities
Anthropic has released Claude Opus 4.5, positioning it as the best model in the world for coding, agentic workflows, and computer use, with pricing reduced to $5/$25 per million input/output tokens. The model demonstrates significant token efficiency gains—up to 65% fewer tokens than prior models on equivalent tasks—alongside improvements in long-horizon autonomous task execution, multi-step reasoning, and self-improving agent behavior. The release is accompanied by updates to Claude Code, the Claude Developer Platform, and integrations with Excel, Chrome, and desktop environments. Early partner feedback from GitHub Copilot, Cursor, Notion, Warp, and others reports measurable benchmark improvements and new use cases previously out of reach.
Anthropic launches Claude 2 with 100K context window and improved coding, reasoning, and safety
Anthropic released Claude 2, featuring a 100K token context window, improved performance on coding (71.2% on Codex HumanEval, up from 56.0%), math (88.0% on GSM8k), and legal reasoning (76.5% on the Bar exam multiple choice section). The model is available via API at the same price as Claude 1.3 and through a new public beta at claude.ai for US and UK users. Safety improvements include a 2x reduction in harmful outputs on internal red-team evaluations compared to Claude 1.3. Early API partners include Jasper and Sourcegraph.
Claude Opus 4.8 Launches with Improved Honesty; Anthropic Previews Mythos-Class Models and Dynamic Workflows
Anthropic released Claude Opus 4.8 with improvements in coding, reasoning, agentic tasks, and notably better uncertainty flagging—approximately four times less likely than Opus 4.7 to let code flaws pass uncommented. Alongside the model, Anthropic introduced dynamic workflows in Claude Code enabling tens to hundreds of parallel subagents for large-scale engineering tasks, an effort-control slider, and a 3x price cut on fast mode. Anthropic also previewed Mythos-class models, positioned above Opus in capability, currently available to a limited set of organizations for cybersecurity work pending broader safety clearance. The same digest covers MiniMax M3 (open-weights, ~60% SWE-Bench Pro), Nvidia's RTX Spark superchip, Cosmos 3 world model, and a GR00T/Unitree robotics partnership.
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.
The Batch: Claude Mythos 5 / Fable 5 debut, Apple AFM 3, Google Live Translate, OpenAI IPO filing, FrontierCode benchmark
Anthropic launched Claude Fable 5 (a safety-guardrailed model) and Claude Mythos 5 (same underlying model with safeguards removed, for vetted cyberdefense/infrastructure users via Project Glasswing with US government collaboration), both priced at $10/$50 per million tokens. Apple released five new Apple Foundation Models (AFM 3) spanning on-device and cloud tiers, built with Google and Nvidia infrastructure. Additional headlines cover Google's Gemini 3.5 Live Translate (70+ languages, real-time), OpenAI's confidential SEC IPO filing, a NotebookLM upgrade to Gemini 3.5, and Cognition's FrontierCode benchmark for code-quality evaluation where Claude Opus 4.8 leads at 34.3%.
