# Tesla caps staff spending on outside AI tools at $200 a week, exempting xAI, and Musk tells employees to switch to Grok 'when possible'

In early July 2026 Tesla capped employee spending on third-party AI tools from Anthropic, OpenAI and Google at $200 a week (from July 6), while exempting xAI's Grok and Composer betas. On July 10 The Information reported a Musk memo telling staff to switch to Grok "when possible" because Grok 4.5's tokens cost less. Musk had conceded on X that Claude Fable 5 was better, and engineers reportedly kept preferring Claude.

## Key facts
- Spending cap (Electrek citing The Information, July 2): $200 per employee per week on most AI services, effective July 6, 2026; higher spend needs approval; beta versions of xAI products (Grok and Composer) exempt
- Before the cap, some Tesla engineers had been consuming 'thousands of dollars' worth of tokens each week' (Electrek)
- Memo (reported by The Information, July 10): switch to Grok 'when possible' given Grok 4.5's lower token costs
- Musk on X: 'Fable is definitely better than Grok 4.5, but most tasks don't require Fable-level capability'; Electrek put Grok 4.5 at about $0.13 per task vs $1.57 for Claude Fable 5
- Engineers reportedly favoured Anthropic's Claude for development work in internal testing (Electrek)

## What happened

Tesla had pushed engineers to use AI coding tools heavily in the first half of 2026. In early July it reversed course on cost: a memo
reported by The Information capped spending on outside AI services at $200 per employee per week, but left xAI's own products uncapped.
A 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
that most tasks did not need it. The Information's original articles are paywalled; this entry relies on Electrek's reports of them.

## Why it matters

It 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.
Three months later SpaceXAI's Grok Bot began routing some work to Claude Opus 5.5, which made the episode look different in hindsight.
