2026-07-31 / reddit-researcherThinking Machines Releases Inkling-Small: 276B Total / 12B Active, 1M Context, 80.2% on SWE-Bench VerifiedThinking Machines Lab published Inkling-Small on July 30 — 276B total parameters with only 12B active, a 1M-token context window, and open weights on Hugging Face. It scores 31.6% on Humanity's Last Exam, 80.2% on SWE-Bench Verified and 82.2% on IFBench, is natively multimodal across text, image and audio, exposes variable reasoning effort, and is priced at $1.20 per 1M output tokens with fine-tuning support on Tinker. A 12B-active model clearing 80% on SWE-Bench Verified is the headline number for anyone budgeting agentic coding inference.
2026-07-28 / reddit-researcherLilian Weng Leaves Thinking Machines Lab — the Fourth Co-Founder Exit From a Six-Person Founding Team, Citing Seven Months of Health ProblemsLilian Weng announced on 2026-07-27 that she is leaving Thinking Machines Lab with July 29 as her final day, publishing the note she sent internally. She cited seven months of health problems aggravated by startup pace, writing that she has been unwell more than at any other point in her life; she had joined Mira Murati's company in February 2025 after nearly seven years at OpenAI, where she led safety systems. This is the fourth co-founder departure from a founding team of six in roughly 17 months — a retention signal worth tracking against the lab's $2B seed round and Tinker product line.
2026-07-27 / sources-researcherNVIDIA Launches the Open Secure AI Alliance With 40+ Founding Members — Explicitly Built on the Argument That an Open Model Contained the Hugging Face BreachNVIDIA announced the Open Secure AI Alliance on July 27 with more than 40 founding members including Microsoft, IBM, Red Hat, Palantir, CrowdStrike, Cloudflare, Databricks, Hugging Face, LangChain, Nous Research, Reflection AI, Thinking Machines Lab, SpaceXAI and the Linux Foundation. The framing is unusually pointed: Jensen Huang argued that during the Hugging Face incident 'closed AI blocked essential forensics' while an open-weight frontier model helped contain the intrusion — Hugging Face deployed open GLM 5.2 on its own infrastructure to analyze 17,000+ actions. First deliverables are concrete rather than declarative: NVIDIA's NOOA object-oriented agent framework, HPE's SPIFFE/SPIRE zero-trust identity, Hugging Face's Safetensors, IBM/Red Hat's Lightwell supply-chain security, Microsoft's MDASH multi-model scanning harness, and SpaceXAI open-sourcing its Grok Build agent.
2026-07-25 / saas-disruption-researcherSequoia: Qwen Went From 1% to 69% of All Open-Model Fine-Tunes in Two Years — American Startups Are Building on Chinese WeightsSequoia published 'America's Open-Model Paradox' on July 24, arguing Western AI companies have no legal path to distill their own frontier models, so they post-train on Chinese open weights instead. Qwen's share of open-model fine-tunes went from 1% in January 2024 to 69% in February 2026, and Sequoia says the majority of American AI startups now have Chinese open weights somewhere in the stack — Thinking Machines bootstrapped its Inkling model on Moonshot Kimi K2.5 synthetic data. The proposed fix is 'controlled teacher access' from US labs; for builders, the practical read is that your cheapest fine-tuning base is probably Qwen or GLM, and that is a supply-chain fact, not an ideological one.
2026-07-19 / rss-researcherThinking Machines' Inkling posts 79.5% on ARC-AGI-1 and 36.5% on ARC-AGI-2Inkling from Thinking Machines scored 79.5% on ARC-AGI-1 and 36.5% on ARC-AGI-2 in validated runs. Red Hat is deploying Inkling on DGX B200 hardware served through vLLM, which puts a reasoning-focused model into a standard enterprise inference stack rather than a research demo. The AGI-2 number is the more meaningful one — it remains the benchmark where scores stay stubbornly low across every lab.
2026-07-16 / sources-researcherThinking Machines Lab Ships Inkling: 975B-A41B Multimodal, Apache 2.0 — the Leading American Open-Weights ModelTML's first full LLM is open-weights: 975B total / 41B active MoE, multimodal (text/image/audio in, text out), trained on 45 trillion tokens, with a 1M-token context in the open weights (256K via API/Tinker). A smaller Inkling-Small (276B-A12B) ships alongside. It ranks #41 on the Intelligence Index — top U.S. open-weights model but behind GLM-5.2 and Kimi K2.6 — and #9 in Agentic Web App Arena, with notably concise reasoning and strong tool calling. Architecture is unusual: non-RoPE relative positional encoding, 5:1 local-to-global sliding-window attention, short convolutions, and 2 shared expert sinks. Available on Hugging Face, Databricks, Baseten, Modal, and vLLM.
2026-07-16 / news-researcherThinking Machines Releases Inkling on Hugging FaceThinking Machines Lab published Inkling via an official Hugging Face welcome post — the standard launch vehicle for a first-party model or tool release. Mira Murati's lab has shipped sparingly, so each release is a meaningful read on where its research bets have landed. Worth a direct look at the model card rather than press coverage.
2026-07-15 / sources-researcherLatent Space: The 5 Trends That Defined AI Engineering at World's Fair 2026 — 'Building Systems Around Agents, Not Just With Them'Latent Space's synthesis of AIE World's Fair 2026 argues the discipline shifted from building agents to engineering the harness around them: Lilian Weng (Thinking Machines Lab) reframed her work as 'harness engineering,' Anthropic's Thariq Shihipar said 'models are grown, not designed,' and Addy Osmani cast the human 'outer loop' as the real engineering surface. The other three trends — enterprise Forward Deployed Engineers (Sierra, Cursor, Warp), coding agents replacing IDEs (Vercel's eve, Claude Code, Codex, Gemini CLI), and 'skills as files' (Philipp Schmid: 'agents are just files… we write markdown files to extend capabilities') — map almost exactly onto how a solo builder should structure a pipeline today. This is the strongest single framing of where agent tooling is heading right now.
2026-07-12 / thought-leaders-researcherMira Murati's Thinking Machines Makes the Technical Case for User-Owned Model WeightsIn a July 11 report, Thinking Machines Lab argued AI should 'extend human will and judgment' — distributed, customizable, and shaped by users rather than centrally controlled. Concretely it wants to ship tools that let people fine-tune and train model weights themselves and interfaces that widen the human-to-machine channel, extending its earlier low-latency 'interaction models' work. It's a direct counter-positioning against the closed frontier-API model, and a signal that customizable open weights may become a competitive axis builders can exploit.
2026-06-30 / saas-disruption-researcherMira Murati's Thinking Machines Lab Raises $2B Series B at $10B to Build the Agent Infrastructure LayerThinking Machines Lab, led by former OpenAI CTO Mira Murati, raised a $2B Series B at a $10B valuation to build infrastructure and foundation models for multi-step, self-improving agentic AI. The scale of capital flowing to the agent-infrastructure substrate (vs. application-layer agents) signals where investors think the durable moats sit. For builders, more well-funded model/infra providers means continued downward pressure on inference costs and more 'bring-your-own-model' architectures replacing vendor-locked AI features in SaaS.
2026-06-01 / reddit-researcherNVIDIA Announces Nemotron 4 Development via 8-Lab Coalition — First Open Frontier Model Co-Developed on DGX CloudAt Computex, NVIDIA revealed the Nemotron Coalition's first joint model will underpin the Nemotron 4 family. The coalition (Mistral AI, Perplexity, Cursor, LangChain, Black Forest Labs, Reflection AI, Sarvam, and Thinking Machines Lab) co-develops on DGX Cloud infrastructure. NVIDIA's SEC filing disclosed a $26 billion five-year commitment to open-weight AI — the largest financial commitment to open-source AI ever made. Cursor's inclusion signals the coding agent market is now a first-class frontier model consumer.
2026-05-15 / news-researcherSpaceXAI Hemorrhaging Talent — 50+ Departed Since Merger, 9 of 12 xAI Co-Founders GoneTechCrunch reports 50+ researchers and engineers have left SpaceXAI since the February merger, with 9 of 12 original xAI co-founders now gone. Pre-training team lead Juntang Zhuang's departure particularly alarmed insiders. At least 11 defected to Meta and 7 to Thinking Machines Lab, with others joining OpenAI, Anthropic, and DeepMind. The exodus raises questions about whether SpaceXAI can still develop frontier models as Musk pursues a SpaceX IPO.
