I Did the Math on Grok 4.5. The $6 Output Price Is the Real Story.

Short summary

Grok 4.5's real differentiator is its $6/1M output token price — roughly 2.5x–5x cheaper than competing flagship coding models. xAI claims 15,954 average output tokens on SWE Bench Pro versus 67,020 for Opus 4.8 max, making the cost gap even wider in practice. The article provides concrete per-run and monthly cost calculations showing $166–$256/month at 1,000 runs, and recommends canary testing before migrating existing Claude/GPT routes.

• •Grok 4.5 priced at $2 input / $6 output per 1M tokens — aggressive output pricing for coding agents
• •xAI claims 4x lower output token usage vs Opus 4.8 on SWE Bench Pro, compounding cost savings
• •EU API access delayed to mid-July; canary test before ripping out existing routes
