Current flagship: what “Grok 4.x” means in practice
This page is not a press release. It’s the practical answer to: Which Grok should I care about right now, and what does it change in real life?

Facts gate: Live Off Screen Space still lists Grok 4.3 as current/default with 1M context and API near $1.25 / $2.50. Drafts and product chatter also use Grok 4.5, 500k context, and $2 / $6. Before this page goes live, lock one row in 00-facts-and-claims.md and replace every number below. Until then, treat specs as illustrative of the current flagship class, not a contract.This page is not a press release.

In one paragraph
The current flagship Grok is the model behind the “best” experience in the apps, web, API, and (where available) Build/CLI surfaces. Compared with earlier Groks, the pitch is sustained work: multi-step plans, tool use, long threads that don’t fall apart, strong coding/knowledge work, and a voice path that feels usable outside a demo booth.
For Off Screen Space readers that usually means: smarter home planning sessions, longer site-building threads, better research synthesis, and less “I have to restart the chat every hour.”
What actually improved (user-visible)
| Capability | What you’ll notice | Independence angle |
|---|---|---|
| Long context | Whole projects, long PDFs, multi-day threads | Fewer “remind me what we decided” loops |
| Agentic behavior | Plan → do → fix, not one-shot answers | More finished checklists and drafts |
| Coding / builders | Better full-stack and repo-shaped help | Useful if you run small sites |
| Voice | Lower friction, more natural back-and-forth | Car, kitchen, caregiving |
| Tool use | Browse / code / files depending on surface | Research + verify in one flow |
| Speed / efficiency | Feels snappier; sometimes fewer tokens to solution | Less waiting, sometimes lower API cost |
Exact tokens/sec and context numbers belong on the model version page once verified.
Who should “upgrade” attention to this model
Yes, prioritize the flagship if you:
- Keep multi-day projects in one chat (site, renovation, business plan)
- Use voice as a daily driver
- Write code or content systems for real shipping
- Hit rate limits or weak answers on free / older tiers
Maybe skip obsessing if you:
- Only need quick Q&A a few times a week (free tier may be enough)
- Need offline-only AI (Local AI)
- Are blocked by plan price — optimize workflow first, subscription second
Voice Agent Builder (flagship-era feature)
If your account shows a Voice Agent / phone agent builder, treat it as a product of this generation of Grok — not magic from the base chat model alone.
Good for: screening, appointment intake, simple FAQs, after-hours capture. Not for: emergencies, medical triage, guaranteed compliance without reading terms.
Full guide: Voice agents. Don’t bury the whole feature only on this page.
API vs app (same model, different job)
| Surface | Best for |
|---|---|
| App / web | Voice, agents, daily chat, images |
| API | Batch jobs, automations, your own tools |
| Build / CLI (if available) | Repo-aware coding loops |
Pricing note: Consumer plans (Free / SuperGrok / Heavy / X bundles) are separate from metered API. Confirm both on official pages; OSS cards should say “as of [date].”
How it feels day to day (OSS lens)
- Direct tone — less corporate fog; still wrong sometimes
- Long coherence — better partner for smart-home design sessions
- Build, don’t only advise — drafts code, tables, content you can edit
- Still cloud — no network, no flagship
Pair with Limits so trust stays calibrated.

Image ideas
- Dark OSS-style card: “Current default” + verified context + plan tier (typeset in HTML, not AI text).
- Multi-step project strip: research → plan → draft → verify.
- Soft deep-link to Image Studio rather than fake product UI screenshots.
