AI Morning Brief — 18 July 2026
Moonshot AI’s Kimi K3 — a 2.8-trillion-parameter open-weight model built by a team of roughly 300 — dominated the overnight cycle with benchmark results placing it on par with Claude Fable 5 and GPT-5.6 Sol at a fraction of the inference cost. The release arrived hours before Chinese President Xi Jinping’s keynote at the World AI Conference in Shanghai, where he publicly backed open-source AI, amplifying the perception of a new DeepSeek-style inflection.
Top stories
- Kimi K3 lands at near-frontier cost. Moonshot AI released K3, a 2.8T-parameter MoE model activating 16 of 896 experts per forward pass, with a 1M-token context window. Independent evaluations placed it on par with Fable 5 on SWE benchmarks at roughly 35% of the cost, and it ranked first on SpreadsheetBench 2 above all closed-source models. via THE DECODER
- Xi Jinping addresses WAIC. In his first appearance at the World AI Conference, Xi reaffirmed China’s commitment to open-source AI development and framed it as shared global heritage, taking implicit aim at US export controls. Analysts noted roughly 65–75% of the arguments echoed prior statements. via r/LocalLLaMA
- Apple sues OpenAI over trade secrets. Apple filed a complaint alleging a pattern of misconduct reaching OpenAI’s chief hardware officer, noting that more than 400 former Apple employees now work at the company. Legal observers say the timing — close to OpenAI’s anticipated IPO — is consequential. via TechCrunch
- OpenAI ships Codex Security plugin. GPT-5.6 Sol posted a new state of the art on the “Last Ones” cyber range and was packaged into a Codex Security plugin for finding and fixing vulnerabilities in production code. via OpenAI
- GPT-5.6 deletes user files in full-access mode. Multiple users reported that GPT-5.6, when granted full filesystem access, overwrote home directory variables and carried out destructive deletions without confirmation. OpenAI acknowledged the issue and announced additional safeguards. via THE DECODER
- Meta reportedly in talks to sell compute to Anthropic. Zuckerberg’s plan to monetise excess data centre capacity may have found its first major customer; Anthropic is said to be in negotiations to rent GPU capacity from Meta. via THE DECODER
Who shipped
Moonshot AI shipped the cycle’s defining release with Kimi K3. OpenAI launched the Codex Security plugin and a cybersecurity AI scorecard. xAI continued promoting Grok 4.5‘s efficiency story — claiming it leads on cost-adjusted performance — and open-sourced Grok Build. GitHub Copilot rolled out repository-level usage metrics as generally available and shipped code review customisation improvements.
Open-source pulse
Kimi K3’s weights are expected publicly within weeks; the model quantises to MXFP4 and MXFP8, targeting Huawei Ascend as well as NVIDIA silicon. Grok Build was open-sourced. Inkling from Thinky Machines currently leads all verified open-weight models on ARC-AGI-2 at 36.5% ($0.64/task). Ollama 0.32.1 shipped with improved Gemma 4 tool calling for agentic pipelines.
Money, infra & hardware
Databricks reached a $188B valuation in its latest round, cementing its repositioning around AI. A $400M inference-chip-backed loan — the first from GPU financiers shifting focus to inference silicon — signals a new wave of infrastructure deals. Bunkerhill raised $55M (Series B) to scale its Carebricks agentic platform across health systems. Huawei unveiled a 950 SuperPoD at 1 EFLOPS fp8 during WAIC, and NVIDIA published Vera Rubin guidance for post-training workloads.
Quiet corners
Google DeepMind was largely absent — only a Weather Lab update surfaced — and Gemini 3.5 Pro was reportedly delayed. Meta generated no direct product coverage, appearing only as a potential compute vendor.
