Grok 4.72026-09-21 18:31:52Grok 4.7 launches at the same price as 4.6, while the older model struggled in an AI StarCraft benchmarkSpaceXAI rolled out Grok 4.7 on Sept. 21, describing it as the company’s strongest model yet for coding and knowledge work. The company said pricing and speed remain in line with Grok 4.6, with access now available through Cursor, Grok Build, and the Grok API. According to SpaceXAI, the new release uses a larger base model than Grok 4.6, underwent longer reinforcement learning training, and was tuned for harder tasks that can take hours to complete. It was also trained to better verify its own outputs, handle longer context windows, and work within the framework used by the company’s resident agent, Grok Bot. SpaceXAI’s own benchmark table showed Grok 4.7 leading in electrical engineering and legal-agent testing, while trailing Fable 5.1 in software engineering and long-duration terminal tasks. In clinical reasoning, it ranked below the two competing models listed. The company also said Grok 4.7 includes a new safety system, allowing only 3.3% of risky dual-use cybersecurity requests in HackerBench v0.3 and scoring 62.4% in the LatchBio biosafety benchmark. A separate discussion on X drew attention to Grok 4.6’s weak showing in Brood War Bench, a StarCraft: Brood War evaluation built by developer Ben Swerdlow. In 171 matches across 19 model and reasoning-setting combinations, Grok 4.6’s three settings lost to all Codex and Claude settings, with its best configuration winning only two of 18 games. The benchmark has not yet posted results for Grok 4.7.410

Elon Musk2026-09-17 21:16:03Bloomberg: SpaceXAI discussed buying data from failed startups to train GrokElon Musk’s SpaceX has internally discussed buying leftover customer files and operating records from startups that have already shut down, according to people familiar with the talks cited by Bloomberg. The conversations are taking place inside SpaceXAI, the artificial intelligence unit created in February after SpaceX merged with xAI, though the discussions are described as informal and may not lead to a deal. The logic is straightforward: high-quality business records are valuable training material for AI models, and data from defunct companies may be cheaper than licensing information from firms that are still operating. The report points to a recent precedent. Google paid $10 million in a bankruptcy auction for Spirit Airlines’ internal records, including about 100 million emails, 500 million Microsoft Teams messages, and decades of employee files, with the data headed into an AI training pipeline. That sale has drawn objections from a flight attendants’ union, which argues in bankruptcy court that removing names from records does not fully protect identities. Bloomberg also noted that Musk told a SpaceX all-hands meeting in August that the company would not stop at buying outside data and would also mine its own, saying the model would 「inherit your thoughts」. SpaceX released Grok 4.5 in July, its first model after the xAI merger closed.440
Elon Musk2026-09-14 11:25:40Musk says Grok 5 may surpass every AI model on the marketElon Musk laid out a fresh roadmap for Grok in a post on social media, saying Grok 4.7 should be roughly on par with Opus 5.0 rather than 5.1, with strengths in some areas and weaknesses in others. He said Grok 4.8 should bring a noticeable jump, Grok 4.9 could reach the Astra/Fable tier, and Grok 5 may outperform every product currently available. Musk had previously previewed Grok 4.8 as a 2.5T-parameter model trained on SpaceXAI’s new C++ software stack. According to him, pretraining is set to finish this week, followed by reinforcement learning. He had also said in late June that Grok’s training and inference stack would be heavily rewritten in C/C++ over about three months, with many intermediate layers removed and specific optimization for Nvidia GB300. The update comes as Grok 4.7 has already been delayed because of RL-related issues. Musk had earlier said the model would launch around Sept. 12, but later acknowledged that it gave up too early on difficult problems and was not strict enough when checking answers.790
SpaceXAI2026-09-14 07:13:07SpaceXAI says unified Grok and Cursor subscription plan is coming within weeksSpaceXAI is working on a new subscription structure for Grok and Cursor, with a unified plan expected within the next few weeks, according to product lead Maxime Prades. The comment came after a user complained that the current lineup is too confusing and suggested cutting it down to two subscriptions, X and Cursor, while bundling Cursor Pro into X Premium+ and discontinuing Grok Build. Prades did not endorse those specific proposals. He said only that a new plan is already in progress and invited the user to review it early and share feedback. The complaint reflects broader confusion around the current setup: Cursor Pro, Pro+, and Ultra include Grok Bot; SuperGrok and X Premium+ can also enable Grok Bot for a Cursor account. Even so, usage across the two sides does not combine, and each subscription still renews separately. Users in the Cursor community have also been asking which option to buy between SuperGrok Heavy and Cursor Ultra, and whether their quotas are shared.870
SpaceXAI2026-09-12 13:36:43SpaceXAI team to livestream a 72-hour startup build using Grok BotThree employees at Elon Musk-backed AI company SpaceXAI are set to run a live event called "Grok Bot Galaxy" from Sept. 15 to 17, attempting to build a startup from scratch in 72 hours. During the stream, they will decide the company name, product, and business plan in real time, while relying on the firm’s AI agent product, Grok Bot, for ideation, planning, product development, and engineering deployment. The event will take place in San Francisco and stream globally each day from 8:30 a.m. to 6:00 p.m. Pacific Time. SpaceXAI was formed after SpaceX acquired xAI in an all-stock deal valued at $250 billion in February, and it later bought coding company Cursor for $60 billion in August. Musk has also recently acknowledged that Grok is not yet the preferred choice in this area, as reports have highlighted misuse of rival Anthropic’s Claude model in cyber operations and fraud.770
SpaceXAI2026-09-11 08:46:16SpaceXAI to livestream a three-day startup build using Grok BotSpaceXAI plans to stage a live three-day startup challenge from Sept. 15 to Sept. 17 at The Howard in San Francisco, with an online stream running at the same time. The event, called Grok Bot Galaxy, asks a simple question on its official page: can three people build a company in three days? The format centers on Matt Palmer, Lauren Tan, and Roshan Sadanani, who will use Grok Bot to move from an idea to a live product. Lauren Tan is identified as a SpaceXAI engineer, while Palmer previously worked at Cursor. The report says SpaceXAI was folded into SpaceX’s AI division from xAI in February, and in June bought Cursor in an all-stock deal valued at $60 billion. Grok Bot, which entered beta on Aug. 11, is described as a persistent agent with its own cloud computer that can sign into tools without APIs. SpaceXAI is using the event to show whether the agent can handle not only coding, but also sales, support, and marketing work.900
