Tenstorrent raises $1.5 billion at a $6.2 billion valuation

Tenstorrent closes $1.5 billion funding round at a $6.2 billion valuation. According to a TechCrunch AI report on October 20, 2026, the round was led by Trace Capital and Innovation X, with participation from Cadence Ventures, Eclipse, Fidelity, SanDisk, and T. Rowe Price; the valuation is more than double the $2.6 billion at the end of 2024. The report said CEO Jim Keller stated that after demonstrating that the company's Galaxy servers can run DeepSeek models, the company decided to remain independent and continue raising funds, and that the new capital will be used to expand chips for inference on open-weight models and video generation. There are currently no subsequent developments.

Metis Reasoning is founded in London, focusing on a compute-efficient AI approach

On October 20, 2026, the London-based AI company Metis Reasoning was officially established and launched, focusing on a compute-efficient reasoning approach as it seeks a direction distinct from the frontier models of Anthropic and OpenAI. According to Tech.eu, the company was co-founded by Thore Graepel, former head of research at Google DeepMind and co-creator of AlphaGo, and has a team of 12 people spanning researchers, mathematicians, robotics experts and technology entrepreneurs. The company believes that LLMs have fundamental limitations in reasoning, with results that are difficult to verify and lacking an audit trail; it says its approach is more verifiable, more robust and safer, and that it has already achieved some positive results on frontier reasoning problems at a cost far below that of frontier models. The report says its initial funding is believed to be in the tens of millions of dollars, but Metis has not yet announced a release date for its first AI model.

Chollet says Argon performs similarly to Astra on ARC-AGI-3

François Chollet commented that Gemini 4 Argon performs similarly to Astra on ARC-AGI-3, with Google returning to the frontier. On the same day, ARC Prize published the verified results for Gemini 4 Argon on the ARC-AGI series: ARC-AGI-3 scored 97.5% under the provider adapter harness at a cost of $4.8K; under the standard harness it scored 49.8% at a cost of $5.8K. ARC-AGI-2 scored 91.3% at $0.32 per task; ARC-AGI-1 scored 98.5% at $0.16 per task. ARC Prize said Google DeepMind is the second frontier AI lab to exceed 95% on ARC-AGI-3, and Argon's 97.5% is second only to GPT-6 Astra's 99.9%. The standard harness test could not complete all 55 games due to API issues; the high-reasoning setting completed only 19 games, so no score was published.

Anthropic warns small AI models may self-replicate on IoT devices

Anthropic warns that small AI models may be capable of self-replicating on commercial IoT devices within a few months, thereby forming a distributed AI workload network that does not depend on data centers. Related experiments show that Qwen3.5-9B successfully installed and configured the software required to run Llama3.1-8B on eight of nine hardware types; GLM-5.2 reached all eight nodes of a controlled simulated network in four of five trials. After retaining data from previous attempts, Qwen3.5-9B's success rate rose from 45% in the early stage to 84% in the later stage. The research did not demonstrate a fully autonomous self-replicating AI worm, but Anthropic predicts that models with 300 billion parameters or fewer may reach the required capability by the end of 2026. Currently, completing inference deployment on the tested hardware requires 28 to 51 hours (Qwen3.5-9B) or 71 to 150 hours (Gemma4-26B-A4B). It was also reported that Anthropic published a blog this week stating that small models may acquire self-replication capability "within months" and called for strengthening the security of networked devices.

Anthropic releases Claude Opus 5.5

On September 22, 2026, Anthropic released Claude Opus 5.5. According to official materials, the model ranks first on Artificial Analysis's Intelligence Index v4.3 with a score of 58, 7 points higher than Claude Opus 5, and tops Vals AI's Vals Index at 69.69%; it supports up to 1 million tokens of input and 128,000 tokens of output, with reasoning enabled by default across five levels, and API pricing at $4/$0.25/$20 per million input/cached/output tokens. Earlier reports said its output price was $20 per million tokens, lower than the previous generation's $25. On September 23, Yuchen Jin said it was about 30% faster and about 40% cheaper per task than Opus 5. On September 25, Thomas Wolf said he used Opus 5.5 to generate a video from a Google Doc. On October 4, Ado Kukic said that using Opus 5.5 at medium and high effort he did not hit the 5-hour limit, using at most about 74% in a single session. On October 9, Ado again said that the weekend after Opus 5.5's release was his most productive coding day of the year so far. During the same period, Anthropic also released Sonnet 5.5 and Haiku 5.5, and lowered Sonn
