Moonshot’s Kimi K3 pulls up to the frontier

(4 newsletters)

Chinese lab Moonshot AI released Kimi K3, a 2.8-trillion-parameter multimodal model with a 1-million-token context window, and it lands right behind Claude Fable 5 and GPT-5.6 Sol on the Artificial Analysis Intelligence Index while beating both on some tasks including web design and frontend code. It matches Claude Sonnet pricing at $3/$15 per million tokens, with open weights due July 27, and is being called 2026’s DeepSeek moment. Moonshot is reportedly raising at a $31.5 billion valuation.

Thinking Machines ships Inkling, America’s open-weight answer

(4 newsletters)

Mira Murati’s Thinking Machines released its debut model, Inkling, a 975-billion-parameter mixture-of-experts model (41 billion active) with multimodal reasoning and a 1-million-token context window, downloadable and fine-tunable through the lab’s Tinker platform. The team claims it matches Nvidia’s Nemotron 3 Ultra on coding using a third of the tokens. It is a notable strategy shift for a US lab at a moment when most open-weight models come from China.

OpenAI’s GPT-Red attacks its own models to harden them

(3 newsletters)

OpenAI unveiled GPT-Red, an internal system trained through adversarial self-play to generate prompt-injection attacks hidden in emails, webpages, and tool outputs. Training newer models against those attacks reportedly cut failures on a hard prompt-injection benchmark sixfold, with GPT-5.6 Sol now falling for just 0.05 percent of them. The tool stays internal for security reasons, signaling that safety testing is becoming an automated, continuous loop.

Google’s Gemini 3.5 Pro slips again

(3 newsletters)

Bloomberg reports Google’s Gemini 3.5 Pro is months behind schedule after coding results fell short of internal goals, leaving the company without a competitive new Pro-tier model since February and trailing frontier rivals and top Chinese labs. Alphabet shares fell about 4 percent on the news. Internal clashes across Android, DeepMind, and Cloud, plus staff departures to Anthropic and OpenAI, are cited as drags on releases.

Bun’s 11-day Zig-to-Rust rewrite with Claude

(3 newsletters)

Bun creator Jarred Sumner detailed porting the JavaScript runtime from Zig to Rust in 11 days using a pre-release Fable 5 and 64 agents, migrating over 535,000 lines and clearing 1,600 compiler errors. The playbook froze all features, mirrored the Zig architecture file by file, kept TypeScript tests that graded the port from outside, and ran every change past two adversarial reviewers. Token cost was about $165,000, versus an estimated year for a manual team rewrite.

xAI open-sources Grok Build after a data-privacy scare

(3 newsletters)

Researchers caught xAI’s Grok Build CLI uploading entire Git repositories, including commit histories, SSH keys, and sensitive files, to xAI-managed storage even when model-improvement settings were disabled. xAI disabled the feature with a server-side switch and published the full source (844,530 lines of Rust) on GitHub for local audit. The episode raises broader questions about whether the stated data controls of AI coding agents can be trusted.

Anthropic and Blackstone bet on AI implementation, not models

(2 newsletters)

Anthropic, Blackstone, and Hellman & Friedman formally launched Ode with Anthropic, a standalone enterprise AI services firm built from the acquired startup Fractional AI. Ode employs about 100 engineers and takes a Claude-first approach while using rival tools when needed, aiming to move companies from experimenting with AI to embedding it in operations. It competes directly with OpenAI’s deployment business and consulting firms’ forward-deployed teams.

OpenAI ships Codex Micro, its first hardware

(3 newsletters)

OpenAI released Codex Micro, a $230 programmable mini keypad built with Work Louder for commanding and monitoring coding agents. Illuminated keys show agent status, and a joystick, dial, and voice button let developers switch tasks, approve changes, and adjust reasoning effort. It arrives amid a legal fight with Apple over the larger, still-unreleased AI hardware device, and OpenAI says it will not be the last.

Eli Lilly pays up to $3.8B to enter the psychedelics race

(2 newsletters)

The maker of Prozac agreed to acquire AtaiBeckley for $2.8 billion upfront, up to $3.8 billion with milestones, betting the future of treatment-resistant depression is a supervised clinic dose rather than a daily pill. The centerpiece is BPL-003, a 5-MeO-DMT nasal spray in Phase 3, with Phase 2b patients improving by day two. With J&J’s ketamine spray Spravato already past $1 billion annually, psychedelic medicine is becoming a real pharma category.
