Grok 4 Retirement May 2026
xAI's current pricing page lists Grok 4.3 and Grok 4.20 models as the relevant current pricing routes. For LangCopilot, that means old Grok 4 pages should stop being the main crawl target.
The practical replacement is:
| Old intent | Replacement | Why |
|---|---|---|
| Grok 4 API pricing | Grok 4.3 token calculator | Current 1M context route |
| Grok 4 long context | Grok 4.20 multi-agent calculator | 2M context route |
| Grok vs OpenAI | GPT-5.5 vs Grok 4.3 pricing | High-intent current comparison |
Current xAI prices
| Model | Context | Input / 1M | Cached input / 1M | Output / 1M |
|---|---|---|---|---|
| Grok 4.3 | 1M | $1.25 | $0.20 | $2.50 |
| Grok 4.20 multi-agent | 2M | $1.25 | $0.20 | $2.50 |
| Grok 4.20 reasoning | 2M | $1.25 | $0.20 | $2.50 |
| Grok 4.20 non-reasoning | 2M | $1.25 | $0.20 | $2.50 |
SEO handling
Old Grok routes should not be expanded into thousands of pairwise compare pages. The cleaner pattern is:
- keep current Grok 4.3 and Grok 4.20 calculators indexable;
- remove retired Grok routes from the sitemap;
- keep only high-intent comparisons such as GPT-5.5 vs Grok 4.3;
- add a migration article like this one so users and crawlers understand what replaced the old route.
Calculator checklist
When migrating Grok traffic, verify cached-input cost separately from standard input cost. A long-running agent can look much cheaper if most repeated context hits xAI's cached input rate.
