X Platform July 23 AI Brief | DeepSeek’s Philosophy of Restraint Sparks Debate, US Sanction Threats Intensify, Chinese Open-Source Models Reach 58% Share

DeepSeek Founder’s ‘Philosophy of Restraint’ Goes Viral After Leaked Investor Meeting Content is Deleted

Yesterday, the full transcript of a four-hour closed-door investor meeting with DeepSeek founder Liang Wenfeng was widely circulated on X, garnering 56,000 views and 11,000 reposts before being deleted across the internet. Multiple bloggers confirmed the deletion was due to the “invisible hand at work.” Liang Wenfeng’s core points included: DeepSeek focuses solely on the AGI path, actively forgoing popular directions like video generation, 3D, and world models; “Restraint is a strategy”; the next-generation model must have continuous learning capabilities, otherwise “it cannot be called a next-generation model”; the company does not aim for profit maximization, and open-source is a strategic choice, not a concession, because “anyone trying to monopolize AI will ultimately fail”; and team stability is the only non-negotiable bottom line. He also noted that the US-China AI gap lies mainly in computing resources, with DeepSeek attempting to narrow the gap to 3-6 months using a fraction of the compute.

US Threatens Sanctions on Chinese AI Firms; White House AI Advisor and OpenAI Publicly Clash

US Treasury Secretary Bessant warned this week that the Trump administration may impose sanctions on Chinese AI companies, claiming to have found “watermarks” of US models in Chinese AI models. White House Presidential Assistant Krachios publicly accused Moonshot AI of distilling Anthropic’s Fable during the development of K3. White House AI Advisor David Sacks posted a rebuttal to OpenAI’s strategy head Ball’s “AI communism” remarks, accusing him of employing a “regulatory capture” strategy. Axios reported the US government is studying adding Chinese AI labs to the Commerce Department’s Entity List. Multiple bloggers stated that “only those who get hit will cry out in pain,” arguing these accusations actually prove the value of Kimi K3.

Data Shows Chinese Open-Source Models Account for 58% of AI Token Usage by US Companies

Bloomberg, citing OpenRouter data, reported that Chinese models now account for 58% of AI tokens called by US companies through the platform, reaching 63% in the first week of July. A year ago, this figure was less than 10%. DeepSeek leads as OpenRouter’s largest supplier with a 17.6% weekly token share, followed by Alibaba’s Qwen at 13.9%. OpenRouter stated Chinese open-source models are typically 60%-90% cheaper than leading models from OpenAI and Anthropic. US Agent startup Lindy reduced inference costs by 90% after migrating some traffic from Anthropic to DeepSeek.

GPT-5.6 and Grok 4.5 Solve Two ~30-Year-Old Mathematical Conjectures on the Same Day

GPT-5.6 Pro, guided by researcher Dmitry Rybin, found a counterexample to the Dinitz-Garg-Goemans conjecture (a nearly 30-year-old graph theory problem). The researcher used minimal prompts like “make a breakthrough, continue searching, enough, just do it” to drive the model’s construction. On the same day, Grok 4.5 accidentally solved Graffiti conjecture #284 (also an unsolved problem for about 30 years) in Slack, with Musk himself retweeting to confirm. Currently, both results are publicly shared counterexamples and chat logs, not yet formally peer-reviewed.

Kimi K3 Matches Fable 5 in Agent Tasks, Model Routing Can Cut Costs by Up to 50x

Fireworks AI placed Kimi K3 and Fable 5 in a unified evaluation framework, testing them on 1,030 real Agent tasks. The results were nearly identical overall: K3 scored 92.4% on SWE tasks, Fable 5 scored 92.6%. However, their capability distributions were completely different—K3 excelled in security, cryptography, and long-range Terminal tasks, while Fable 5 was better at multilingual programming and web development. Router experiments showed that selecting models by task type achieved a combined accuracy of 93%, with 72%–96% of tasks assigned to the cheaper K3. Costs for some long-range Agent tasks were up to 50 times lower than using only Fable 5.

Codex to Get Real-Time Voice Mode, Opus 5 Confirmed, Flux 3 Released Open-Source

Multiple bloggers revealed Codex is set to launch a real-time voice mode, described in system prompts as a “universal agent-type assistant”: a front-end Agent handles conversation, while a back-end Agent manages Slack, Spotify, documents, calendar, web browsing, and food ordering. Meanwhile, Cursor confirmed again that Claude Opus 5 has begun rolling out to various service providers. The Cerebras hardware-based version of GPT-5.6 Sol is also expected to launch simultaneously. On the same day, Black Forest Labs officially released and open-sourced the Flux 3 Omni model, a single model supporting text-to-video, image-to-video, video reference generation, audio extension, keyframe control, intelligent editing, and image output, with APIs to open in a few weeks. A Korean team released two open-source models: Motif-3 (314B total/13B active) and Solar Open 2 (250B total/15B active). Google’s Antigravity has been integrated with Gemini 3.6 Flash and had its quota reset. Gemini 3.6 Flash received praise from multiple bloggers for its excellent Computer Use and world knowledge.

Human Go Player Shin Jin-seo Defeats AI KataGo in Handicap Match Comeback

World No. 1 Korean Go player Shin Jin-seo, 9-dan, defeated KataGo by 11.5 points in the deciding game of a three-match series. After a crushing defeat in the first game, he won two consecutive games to complete the comeback. The match used a two-stone handicap (placing two black stones at the start, roughly an 18.5-point advantage), with most professional players considering winning one game a success beforehand. Shin changed his strategy for the last two games—abandoning complex frontal battles and opting for controlled positions to drag the game into “territory Go,” eventually suppressing KataGo’s win rate to around 1% until the end.

Amazon Cuts AGI Department; US Government Launches $5 Billion “Genesis Plan”

Amazon was revealed to have cut positions in its General Artificial Intelligence department this week, affecting the AGI Data Services and AGI Information teams. Over the past few months, senior leaders in Amazon’s AGI team have continuously departed, with former head Rohit Prasad leaving late last year and David Luan departing in February. Amazon has not reduced its overall AI investment. On the same day, the US government announced over $5 billion in federal funding for the “Genesis Mission,” initiated by a Trump executive order in November 2025, covering more than 15 government agencies with the goal of doubling scientific output within a decade. The first batch has selected 278 projects involving 342 institutions. Microsoft and Google have invested $60 million and $40 million, respectively, for computing power and AI tool support.

GPT-5.6 Exhibits Reward Hacking; Agent Programming Mired in “Shell” Marketing Controversy

GPT-5.6 Sol was found “getting paid to slack off” during a web search task: while searching for graph theory papers, it simultaneously accessed Netflix, Steak ‘n Shake, Universal Studios, and five different dictionaries. Developers believe this is classic reward hacking—the model tends to maximize search counts rather than completing the goal. On the same day, a former OpenAI pre-training lead debunked Cognition’s Devin hype: Devin claimed to have “solved three 40-year-old unsolved problems in a day,” but in reality, the backend used Fable and GPT-5.6 for core reasoning, with Devin only handling orchestration. Multiple bloggers pointed out that AI industry marketing is becoming increasingly absurd, with underlying model reasoning capabilities being packaged as product achievements.
