Claude went down twice in two days — 529s across Claude.ai, the API, and Claude Code

Claude went down twice in two days — every model returning "529 Overloaded" across Claude.ai, the API, Claude Code, and Claude Cowork: roughly three hours Wednesday evening, then almost five more this morning, with a third, smaller incident opened just after. Kimi K3's open weights are now actually running on home hardware — independent reports, real numbers, about 4 tokens a second. GitHub's free model playground, GitHub Models, shuts down for good today after a month of warnings. And GitHub's Copilot code review can now call a repo's own tools and pull live context from MCP servers. The daily pulse of AI coding tools — what shipped, what matters, what's next.

When the tools go down

Claude went down twice in two days — 529s across Claude.ai, the API, and Claude Code

Anthropic's status feed logged two full outages in under 24 hours: Wednesday 19:49–22:36 UTC (~2h47m) and this morning 05:57–10:48 UTC — ~4h51m, longer than the first — both hitting the same four surfaces (claude.ai, the API, Claude Code, and Claude Cowork), with every model returning 529 Overloaded instead of finishing requests. A third, smaller incident — degraded Opus 4.8 performance — opened at 13:43 UTC and was still open as we published. Anthropic hasn't said what caused any of them. If you were running a long Claude Code session either afternoon, you hit a dead session with no checkpoint — a different failure than a rate limit, and the thing every team's Slack was talking about.

The open-weights story grows hands

Kimi K3 runs at home — first independent reports: ~4 tokens/sec on a 594GB build

Two days after Unsloth started publishing compressed builds of Kimi K3's open weights (1.56TB shrunk to 594GB), r/LocalLLaMA's top threads are no longer the authors' — they're run reports: a home-lab setup pushing roughly 4 tokens/sec, with hardware specs, quant choices, and failure modes in the comments. The practical read: K3 at home is real but marginal — interactive-assistant speed, not coding-agent speed, and the floor is still a workstation, not a laptop.

Deadlines and defaults that moved

GitHub Models — the free multi-model playground — shuts down for good today

The playground, model catalog, inference API, and bring-your-own-key endpoints all stop working today — the last step of a retirement GitHub announced July 1 and rehearsed with two scheduled brownouts (July 16 and 23). GitHub's advice: move model experimentation to Microsoft Foundry, and route AI workflows through Copilot instead. If your team used GitHub Models to prototype against multiple providers without standing up separate cloud accounts, that path closes today.

In June, we announced that we are retiring GitHub Models and closed it to new customers. We’re now sharing the timeline for the next step: GitHub Models will be fully…

Copilot code review can now call your team's own tools — agent skills and MCP go GA

Copilot code review can now invoke a repository's own SKILL.md-defined tools (under .github/skills) and pull live context from MCP servers — issue trackers, docs, service catalogs — while reviewing a PR. Generally available as of yesterday for Copilot Pro, Pro+, Business, and Enterprise, and review comments now say when a skill or an MCP server produced them. It's the same MCP that went stateless this week showing up as a concrete feature a day later: review comments built from your team's actual runbook instead of generic pattern-matching.

Claude's connectors now speak the new MCP spec — the 950+ connector directory supports the 2026-07-28 stateless spec end-to-end: embedded UI, enterprise-managed auth, observability, and private-network tunnels (research preview). The spec change we led with yesterday, landing in the product a day later.
