GPT-5.5 Instant replaced GPT-5.3 as ChatGPT's default, Codex shipped Goal Mode and richer MCP, and a GPT-5.6 entry briefly surfaced in OpenAI's Codex logs. Here is the complete May 2026 OpenAI changelog and what it means for developers.
Cohere released Command A+ on May 20, 2026: a 218B sparse Mixture-of-Experts model with 25B active parameters, Apache 2.0 licensed, that runs on as few as 2 H100 GPUs. Built for sovereign, on-prem enterprise agents with native citations.
xAI's Grok 4.3 lands with a 1M token context window, native video input, and aggressive pricing at $1.25 input / $2.50 output per million tokens. Here is what changed from Grok 4.20, how it benchmarks against Claude Opus 4.7, GPT-5.5, and Gemini 3.1 Pro, and when it is the right tool to reach for.
Anthropic Mythos is the frontier preview model unveiled April 7, 2026: stronger than Opus 4.7 on math and security, withheld from public release, shipped only via Project Glasswing to ~50 defensive-security partners.
Claude Mythos, Opus 4.7, and GPT-5.5 shipped within three weeks of each other in April 2026. We break down which frontier model wins on coding, reasoning, vision, cost, and which one your team should actually pick.
Alibaba's Qwen 3.7 Max launched May 20, 2026 with a 1M-token context, native extended-thinking mode, and benchmark wins on SWE-Pro and Terminal-Bench. Here's how it compares to Claude Opus 4.7, GPT-5.5, Gemini 3.5 Flash and DeepSeek V4, what it costs on DashScope, and when to pick it.
Google dropped Gemini 3.5 Flash and Gemini Spark at I/O 2026. A frontier-grade Flash model that outruns 3.1 Pro, and a persistent personal agent built on top of it. Here's what shipped, what's rumored, and where it fits next to Claude Opus 4.7 and GPT-5.5.
A practitioner's roundup of every AI model release that mattered in May 2026 — Anthropic Mythos, Gemini 3.5 Flash, Qwen 3.7 Max, Mistral Medium 3.5, ERNIE 5.1, and Subquadratic's 12M-token SubQ. Benchmarks, pricing, availability, and what to actually use.
Baidu's ERNIE 5.1, released May 8 2026, became the first Chinese LLM in the global Search Arena top 5. Here's what it does, how it compares to DeepSeek V4 and Qwen, and when teams outside China should actually use it.
Mistral Medium 3.5 is a 128B dense model with built-in reasoning, coding, and agentic capabilities. Le Chat Work Mode turns it into a multi-tool agent. Here's what's new, what it costs, and when to actually pick Mistral over Claude or GPT.
Subquadratic, a Miami startup, launched SubQ on May 5, 2026 — the first frontier LLM with a 12-million-token context window, built on a new Subquadratic Selective Attention (SSA) architecture. Here's what's verified, what's plausible, and what to actually do with it.
What LM Studio is, how to install it on Mac, Windows and Linux, how the OpenAI-compatible server works, MLX vs llama.cpp on Apple Silicon, document chat (RAG), the lms CLI, and where it beats Ollama and llama.cpp.
Quick answer. Cherry Studio is a free, open-source desktop client (Mac, Windows, Linux) that gives you one chat interface for OpenAI, Anthropic, Google Gemini, DeepSeek, Mistral, Qwen and local Ollama or LM Studio models. Install it from cherry-ai.com or GitHub Releases, paste your API keys in Settings → Model Providers,
