The most important thing about Grok Build and the 4.5 release is that it is genuinely so useful for real-world work
X Freeze@XFreeze· 10. Juli 2026Grok 4.5 just topped Perplexity’s WANDR orchestrator evaluation
It scored higher than every other tested configuration at just $4.76 per trial....roughly half the cost of Opus 4.8
Grok 4.5 is becoming the powerful brain coordinating entire agentic workflows
It’s now available

Built with two prompts and /goal!
Jayden Davis@JaydenDavisNC· 10. Juli 2026Grok 4.5 in Grok Build is insane for 3D game dev🤯
I ran a detailed prompt using the /goal feature and I created this in only two prompts. Took roughly an hour.
The model rigged all the enemy humanoids and made a fleshed out map and AI logic.

Try Grok 4.5 in Perplexity
Perplexity@perplexity_ai· 10. Juli 2026Grok 4.5 is now available as an orchestrator model in Computer for Consumer Pro and Max subscribers.
We evaluated it against five other orchestrator configurations on WANDR. It scored higher than every other configuration at roughly half the cost of Opus 4.8.

Grok is closing the loop on real-world use cases
Thibault Jaigu@ThibaultJaigu· 10. Juli 2026@OpenAI released 3 new models yesterday and we immediately tested it on our internal benchmark.
All three outperforming gpt-5.5 but @SpaceXAI still the clear winner with Grok-4.5

Mia@MiaAI_lab· 10. Juli 2026Here's one way to get the most from Grok 4.5 ✨
Switching effort to "low" gives strong results on most tasks, near-zero quality loss, big usage savings — plus it's the fastest.

Grok Build
X Freeze@XFreeze· 10. Juli 2026Grok 4.5 with Grok Build just ranked #1 on the SWE-Atlas-QnA benchmark with a score of 84
That puts it level with GPT-5.6 (max) Codex and ahead of Claude Code Fable 5 (max), Opus 4.8 (max), and every other tested coding setup

Grok 4.5 has the best real-world ROI
Julian Solemsli Rian@LORD_RIAN_· 10. Juli 2026Grok 4.5 just did what no other lab has managed: pushed the limits of frontier intelligence AND made it accessible to everyone.
Hopefully this shifts the AI race toward winning on cost too -> frontier intelligence for all, not just the few.
Huge respect to the @SpaceXAI team.

Artificial Analysis
@ArtificialAnlys · 9. Juli 2026
SpaceXAI's Grok 4.5 takes the #1 spot on AutomationBench-AA with a score of 51%, ahead of Claude Fable 5 (49%) and Claude Opus 4.8 (48%) at roughly a quarter of their cost per task - the first model to complete more than half of workflow objectives without breaking any business rules
AutomationBench-AA, our independent leaderboard for @zapier’s AutomationBench, tests whether AI agents can automate real SaaS workflows while adhering to business rules. The test set is private to prevent contamination.
Models complete 657 tasks across 40 simulated app environments including Gmail, Google Sheets, Slack, Salesforce, and HubSpot, and the headline score is the share of objectives completed without violating any guardrails.
Key takeaways:
➤ Grok 4.5 completes more objectives than any other model: It completes 79.9% of task objectives and strictly passes 21.9% of tasks. This is the highest we’ve measured on both outcomes, exceeding Claude Fable 5’s 73.3% objective completion and Claude Opus 4.8’s 19.3% of fully-completed tasks
➤ Grok 4.5 pushes out the Pareto frontier of score vs. cost per task: At $0.34 per task, it is both cheaper and higher-scoring than every other leading model - Claude Fable 5 ($1.35 per task), Claude Opus 4.8 ($1.46), GPT-5.5 (xhigh, $1.28), and Gemini 3.5 Flash (high, $0.49)
➤ It is extremely token-efficient: Grok 4.5 uses ~8k output tokens per task, the fewest of any leading model - less than a quarter of Claude Opus 4.8 (32k) and a third of Gemini 3.5 Flash (24k). Its total token usage of 0.44M per task is among the lowest on the leaderboard. Low cost is driven by this efficiency as well as low token pricing
➤ Grok 4.5 uses fewer turns with many parallel tool use: Grok 4.5 resolves tasks in ~16 turns, fewer than GPT-5.5 (xhigh, 25) and less than half of Gemini 3.5 Flash (high, 35), while making the most tool calls per task of any leading model (52.5). It batches 3.3 tool calls per turn, compared to ~2.5 for Claude Opus 4.8 and ~2.0 for GPT-5.5 (xhigh)
➤ Guardrails still get broken: Grok 4.5 triggers 0.63 violations per task, above Claude Opus 4.8 (0.55) and Gemini 3.5 Flash (0.46). At 13.0 objectives completed per violation, it trails Gemini 3.5 Flash (15.0) and Claude Opus 4.8 (13.5)
➤ Its strongest lead is in the hardest domain: Grok 4.5 completes 71% of Finance objectives, the domain with the lowest average score, ahead of Claude Fable 5 (64%) and Claude Opus 4.8 (62%)
Congratulations to @SpaceXAI and @elonmusk on topping the leaderboard!
