OpenAI's GPT-5.5 Cyber ships gated under the Daybreak program. What 'trusted access' means, the CyberGym-vs-Mythos-5 benchmark claim (and its caveats), and what defenders and developers should take from it.

A coding head-to-head: GLM-5.2's leaderboard-topping text coding vs MiniMax M3's native multimodality, lower price, and MSA long-context speed — with specs, benchmarks, and a clear verdict.

A practical walkthrough for self-hosting GLM-5.2 (744B MoE, 40B active) on llama.cpp. Quant tables, four hardware paths, exact install commands, verification, and a fallback to the Z.ai cloud API if your rig falls short.

Four credible 128GB-class boxes, four very different price points. We synthesise what practitioners with the hardware on their desks are actually reporting.

VibeThinker-3B is WeiboAI's MIT-licensed 3B reasoning model built on Qwen2.5-Coder-3B. We unpack the viral 'Opus 4.5 performance' claim with the actual HF benchmarks.

Z.ai's GLM-5.2: 744B params (40B active), 1M-token context, MIT-licensed weights — still the newest GLM you can self-host while GLM-5.3's weights are pending. Architecture, benchmarks, pricing, and a 3-path local-inference playbook.

Moonshot's open-weights Kimi K2.7 Code goes head-to-head with Anthropic's Claude Opus 4.8. Architecture, benchmarks (and where they don't exist yet), per-task cost, agentic strength, self-host paths, and a clean per-workload verdict.

Two open-weights heavyweights from China go head-to-head for the agentic-coding throne. K2.7 leads on MCP tool-use depth; V4 leads on raw per-token economics and proven independent benchmarks. We break down cost, agentic strength, self-host paths, and pick a winner per workload.

Moonshot's Kimi K2.7 Code and Z.ai's freshly-released GLM 5.2 are both Chinese open-weights coding flagships, both shipped in June 2026, and they trade on opposite axes. K2.7 leads on MCP tool use and pricing; GLM 5.2 leads on 1M context. We pick per workload.

GLM 5.2 ships 1M-token context and MIT open weights on a flat subscription. Claude Opus 4.8 stays the agentic-coding benchmark at premium per-token pricing. We compare cost, agentic strength, self-hosting and pick a winner per workload.

Two open-weights heavyweights from China go head-to-head for the agentic-coding throne. GLM 5.2 leads on context window; DeepSeek V4 leads on token economics. We break down cost, agentic strength, self-host paths, and pick a winner per workload.

OpenAI's flagship versus Z.ai's freshest open-weights challenger. GPT-5.5 holds frontier coding benchmarks; GLM 5.2 ships a 1M window and self-hostable weights. Where each actually wins for engineering teams.

How Moonshot's open-weight Kimi K2.7 Code stacks up against Claude Opus 4.8, GPT-5.5, and DeepSeek V4 for agentic coding — on price, context, and the benchmarks that exist. K2.7's scores are Moonshot-reported only, so the verdict is subject to change once independent results land.

Moonshot AI's Kimi K2.7 Code — a 1T-parameter open-weight coding model with a 256K context, ~30% fewer thinking tokens than K2.6, and strong MCP tool-use. Benchmarks, pricing, API, and local-deployment guide.

Anthropic's first publicly available Mythos-class model, released June 9, 2026. Third-party benchmarks, pricing, context window, availability, the safety reroute to Opus 4.8, and how it compares to GPT-5.5 and Gemini 3.5.

Anthropic launched Claude Opus 4.8 on May 28, 2026: SWE-bench Pro 69.2%, GDPval Elo 1890 (+121 over GPT-5.5), Fast mode 3x cheaper than 4.7, dynamic workflows for hundreds of parallel subagents. Pricing unchanged at $5/$25 per 1M. Full launch breakdown.

Two weeks after Qwen 3.7 Max, Alibaba shipped WebWorld: an Apache 2.0 web world model series that simulates browsers for agent training. Sizes, benchmarks, code, gotchas.

xAI launched Grok Imagine Agent Mode on May 1, 2026 — an infinite-canvas creative agent that plans, generates, edits, and stitches 6-second video clips into longer films. Features, four templates, vs Sora and Veo, pricing, and API examples.

Gemini 3.5 Pro was promised for June 2026 and never shipped. The full delay timeline, what Google has said officially, and what to run instead: 3.7 Flash for most work, 3.1 Pro for Pro-class needs.

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.

DeepSeek made its 75% V4-Pro discount its standing price on May 22, 2026: $0.435/M input, $0.87/M output. Here is what changed, the cost-per-quality math vs Claude Opus 4.7 and GPT-5.5, and why those rates end on August 16, 2026.

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.

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.
