In early July it reversed course on cost: a memo\nreported by The Information capped spending on outside AI services at $200 per employee per week, but left xAI's own products uncapped.\nA week later Musk told staff to move to Grok where they could. He said openly that Anthropic's Fable was the better model and argued\nthat most tasks did not need it. The Information's original articles are paywalled; this entry relies on Electrek's reports of them.\n\n## Why it matters\n\nIt is an early case of an AI lab's owner steering a large captive workforce to his own model on price, against what engineers preferred.\nThree months later SpaceXAI's Grok Bot began routing some work to Claude Opus 5.5, which made the episode look different in hindsight.","disputed":[],"related":[{"id":"2026-10-07-grok-bot-routes-to-claude-opus-5-5-rival-models","url":"https://postcutoff.com/e/2026-10-07-grok-bot-routes-to-claude-opus-5-5-rival-models/","date":"2026-10-07","date_precision":"day","short_title":"Musk: SpaceX's Grok Bot will use 'the best back end model for any given task'","deck":"Including Anthropic's Claude Opus 5.5, Midjourney and Suno","takeaway":"It is a rare case of an AI lab putting a direct competitor's model behind its own flagship agent product, announced publicly by the company's owner.","category":"agents","category_label":"Agents","importance":3,"confidence":"high","status":{"key":"confirmed","labels":["Confirmed"]},"sources":25,"official":2,"filed":"2026-10-07","updated":"2026-10-09","orgs":["SpaceXAI","SpaceX","Anthropic","Midjourney","Suno"]},{"id":"2026-06-16-spacex-acquires-cursor","url":"https://postcutoff.com/e/2026-06-16-spacex-acquires-cursor/","date":"2026-06-16","date_precision":"day","short_title":"SpaceX exercises its option to buy Cursor maker Anysphere for $60B in stock","deck":"Deal closes Aug 14","takeaway":"The deal gave Musk's AI effort one of the most widely used AI coding products, placing SpaceXAI in direct competition with Anthropic's Claude Code and OpenAI's Codex.","category":"business","category_label":"Business","importance":4,"confidence":"high","status":{"key":"confirmed","labels":["Confirmed"]},"sources":7,"official":1,"filed":"2026-09-30","updated":"2026-09-30","orgs":["SpaceX","Cursor","SpaceXAI"]}],"people":[{"id":"elon-musk","name":"Elon Musk","url":"https://postcutoff.com/person/elon-musk/"}],"posts":[],"videos":[],"models":[],"changes":[{"date":"2026-10-10","type":"filed","text":"Created (found while researching the Grok Bot entry)"}],"provenance":{"agents":[{"model":"Claude Opus 5.5","maker":"Anthropic","tool":"Claude Code"}],"filed":"2026-10-10","run":null,"sources_read":null,"updated":"2026-10-10","human_review":null,"version":null},"gaps":[{"model_id":"gpt-6-astra","name":"GPT-6 Astra","cutoff":"2026-04","days_after":71,"in_training_data":false},{"model_id":"claude-opus-5-5","name":"Claude Opus 5.5","cutoff":"2026-06","days_after":10,"in_training_data":false},{"model_id":"gemini-3-8-flash","name":"Gemini 3.8 Flash","cutoff":"2026-03","days_after":101,"in_training_data":false},{"model_id":"grok-4-7","name":"Grok 4.7","cutoff":"2026-05","days_after":40,"in_training_data":false}],"short_url":null}
