Elon Musk has predicted that Grok will begin inventing new applied sciences by 2026 and will uncover new physics as early as subsequent yr.

The forecast got here throughout a livestreamed demo on X on Wednesday night time. Musk mentioned it was solely a matter of time.

“I believe it could uncover new applied sciences as quickly as later this yr. And I’d be shocked if it has not achieved so subsequent yr. So I’d count on Grok to actually uncover new applied sciences which can be truly helpful no later than subsequent yr and perhaps [the] finish of this yr,” Musk mentioned.

“And it’d uncover new physics subsequent yr. And inside two years, I’d say virtually definitely. So simply let that sink in,” he added.

What we find out about Grok 4

At a look

Grok 4, which succeeds Grok 3, includes a 100-fold enhance in coaching in comparison with its predecessor, Grok 2. The mannequin is available in two variations: a single-agent Grok 4 and a multi-agent Grok 4-Heavy that generates a number of reasoning threads.

The system was skilled utilizing xAI’s custom-built supercomputer Colossus, which incorporates 200,000 H100 GPUs. Not like its predecessor, Grok 4 integrates instruments like code, search, and visualization throughout coaching.

In accordance with the xAI crew, the AI mannequin achieved near-perfect outcomes on standardized exams, together with SATs and GREs, throughout numerous disciplines. On the Humanities Final Examination, a difficult 2,500-question benchmark, Grok 4-Heavy solved as much as 50% of the text-only subset.

xAI plans to attach Grok with superior engineering instruments to allow capabilities similar to designing rockets, automobiles, and drugs. The corporate goals to finally combine the AI system with humanoid robots like Tesla’s Optimus.

Superior voice mode

Grok 4 introduces enhanced voice capabilities, including new artificial personalities similar to “Sal,” a deep, cinematic voice, and “Eve,” a British feminine voice.

These voices deliver a extra human-like texture to interactions, making AI conversations really feel much less robotic.

Eve, specifically, demonstrated pure conversational stream, even dealing with interruptions and artistic prompts, similar to improvising an opera about Food plan Coke, with fluency and attraction.

Voice latency has additionally been lower in half, making responses noticeably faster than different AI assistants.

For the reason that launch of voice mode, Grok has seen a tenfold enhance in lively customers, the addition of 5 new voices, and a doubling of end-to-end response velocity.

Inventive and leisure potential

Grok 4’s voice mode can produce unique musical and poetic content material on demand. The crew demonstrated this by having Eve carry out an operatic piece about Food plan Coke.

xAI envisions Grok writing and producing a 30-minute tv episode by the tip of 2025 and a full-length AI-generated movie in 2026. These ambitions shall be powered by enhancements in Grok’s multimodal methods and video era capabilities.

Superior reasoning and benchmark efficiency

Grok 4 units a brand new customary in reasoning benchmarks.

As famous by the crew, it scored 15.8% on the personal ARC-AGI v2 benchmark, changing into the one mannequin to interrupt the ten% barrier in latest months, doubling the efficiency of its closest competitor, Claude 3.5 Opus.

xAI described Grok 4 as its next-generation reasoning mannequin, leveraging ten instances extra compute and built-in instruments used for problem-solving.

API availability and developer instruments

Launched with API entry and a 256K token context window, Grok 4 is already powering enterprise simulations, analysis, and sport improvement.

In exams, it managed merchandising machine stock and technique autonomously, helped CRISPR analysis, and enabled solo sport builders to construct playable prototypes in hours.

Multimodal and future capabilities

Presently, Grok 4’s means to know picture, video, and audio inputs is proscribed, based on the crew. Nevertheless, main upgrades are on the horizon.

Model 7, due in July 2025, will enhance picture, video, and audio understanding. By 2026, Grok is anticipated to generate 3D video games, interactive movies, and real-time media content material utilizing large-scale video fashions.

Coding specialization

To assist builders extra deeply, xAI is making ready a specialised coding mannequin, anticipated to launch in late July or early August 2025.

This mannequin will additional improve Grok 4’s means to deal with software program engineering duties, constructing on its current power in automating repetitive workflows like asset sourcing.

Actual-world affect and scalability

Grok 4 exhibits potential to function at scale, operating simulated companies and integrating with enterprise workflows. It’s already being adopted in analysis and finance, with availability on main cloud platforms from Could 2025.

Accessibility and subscription

Grok 4 entry was restricted throughout the livestream to forestall overload, however expanded availability is being rolled out quickly.

Full entry requires an X Premium+ subscription, whereas these looking for most efficiency can improve to SuperGrok Heavy at $300/month.

Constructed on the Grok 4 Heavy mannequin, it provides increased fee limits, early characteristic entry, and all the advantages of the usual $30/month SuperGrok plan, tailor-made for these looking for top-tier efficiency.
