Felo Search adds Grok 4.5, SpaceXAI's latest coding and agentic AI model. Felo Pro subscribers get 7 days free access.

On July 8, 2026, SpaceXAI released Grok 4.5 — the first model jointly developed since SpaceX's acquisition of Cursor and the merger of xAI into the SpaceX ecosystem. It's priced aggressively at $2 per million input tokens and $6 per million output, trained on tens of thousands of Nvidia GB300 GPUs, and built for coding, agentic workflows, and knowledge work.

Today, Felo Search is adding Grok 4.5 as a selectable search model. Felo Pro subscribers can experience it free for 7 days — starting right now.

Felo Search Now Supports Grok 4.5 — Terminal-Bench 83.3%, 5x cheaper, 4.2x fewer tokens, Free 7-Day Trial for Pro Users

What Is Grok 4.5?​

Grok 4.5 sits at the intersection of two major industry shifts. SpaceX acquired Cursor for $60 billion in stock in mid-June 2026, and Grok 4.5 is the first fruit of that combined engineering effort — a model that merges SpaceXAI's massive compute infrastructure with Cursor's deep developer data and workflow intelligence.

The headline numbers are impressive:

  • Terminal-Bench 2.1: 83.3% — effectively tied with GPT-5.5 (83.4%) and ahead of Claude Opus 4.8 (78.9%)
  • SWE-Bench Pro: 64.7% — behind Fable 5's 80.4%, but xAI claims Grok 4.5 uses 4.2× fewer output tokens on the same tasks
  • SWE Marathon: 1st place at 29%
  • Artificial Analysis Intelligence Index: 4th place at 54, at $0.31 per task on AutomationBench (versus $1.35 for Fable 5)

The pricing story is what's making developers pay attention. At $2/$6 per million tokens, Grok 4.5 costs a fraction of what competitors charge — and if the 4.2× token efficiency claim holds up in production, the real-world cost advantage could be even wider.

What Users Are Saying​

We searched X (Twitter) to capture the early reactions from developers, researchers, and AI power users who've been hands-on with Grok 4.5. Here's what people are actually saying:

🚀 "Grok 4.5 Feels Like Crack"​

The most repeated sentiment across X is simple enthusiasm. Developer Elliot Arledge posted:

"My 4 Claude Max plans are out and I didn't have to think twice about switching to Grok Build (4.5 high thinking). The token efficiency, intent understanding, low entropy code gen, harness snappiness are in another world. It's also nice to not have anxiety about it randomly refusing requests or falling back to worse models."

Another user summed it up in four words: "grok 4.5 feels like crack."

💻 Coding and Frontend Strength​

Users are reporting strong performance in both backend and frontend development:

  • One developer compared Grok 4.5's design capabilities to Fable 5, saying it's "on the same level" for frontend work when paired with Cursor.
  • A Japanese developer shared that Grok 4.5 handled Japanese text in generated images correctly — a capability that often trips up coding-focused models.
  • The model's SWE Marathon first-place finish (29%) is getting attention, though some researchers are questioning how reliable the SWE-Bench Pro score of 64.7% is compared to competitors.

💰 The Cost-Performance Angle Is Real​

Multiple users highlighted the pricing as a genuine differentiator, not just marketing noise:

  • "APIで使うAI (LLM) を探すなら Grok 4.5 はダントツ最強コスパモデル" — "If you're looking for an AI for API use, Grok 4.5 is by far the best cost-performance model."
  • Industry analysts point out that Grok 4.5's $2/$6 pricing is well below Anthropic's Fable 5 ($10/$50) and OpenAI's GPT-5.6 ($5/$30) — making it the cheapest frontier coding model on the market by a significant margin.

⚠️ What People Are Concerned About​

No launch is perfect, and users flagged a few real issues:

Developer workflow with Grok 4.5 — code editor showing 4.2x fewer tokens, $2/M input pricing, SWE Marathon #1 metrics

  1. Weekly allowance vs. monthly: SpaceXAI moved from monthly to weekly token allowances. As one user noted, this removes a previous advantage for developers who work in sprints.
  2. Web chat billing: Grok 4.5 web chat usage now counts against quotas, which some see as unnecessary penny-pinching.
  3. Non-coding tasks: Several users questioned whether Grok 4.5 is as strong outside of coding and agentic work — "if it's not good at non-coding tasks, it ain't for me."
  4. Expert mode search quality: One user reported that Grok 4.5's Expert mode "is not that smart at search or current events compared to the older Grok Fast model which leans more on search results."
  5. EU delay: The model is already available globally but won't reach EU users until mid-July — a week behind everyone else.

Why Grok 4.5 in Felo Search Makes Sense​

Felo Search has always been about giving you the right answer — not just a list of links. Grok 4.5 strengthens that mission in several ways:

1. Code-Savvy Answers​

Grok 4.5's deep Cursor training data means it understands developer questions at a fundamental level. Ask it about API design, debugging strategies, or framework comparisons, and you'll get answers that are more technically precise than a general-purpose model could provide.

2. Token Efficiency = Better Cost-Per-Answer​

If Grok 4.5 really uses 4.2× fewer output tokens than competitors on complex tasks, that translates directly into faster, more focused answers in Felo Search. Less rambling, more signal.

3. Agentic Reasoning​

Grok 4.5 was built for agentic workflows — multi-step tasks that require planning, tool use, and self-correction. In a search context, that means better handling of complex, multi-part queries that would stump a standard conversational model.

4. Competitive Pricing Pass-Through​

By offering Grok 4.5 through Felo Search, we're making a frontier coding model accessible to anyone — not just developers with API keys. And for Felo Pro subscribers, the first 7 days are completely free.

How to Try Grok 4.5 on Felo Search​

Getting started takes one click:

  1. Go to felo.ai/search?search_model=grok-4.5
  2. Felo Pro subscribers get 7 days of free access — no extra charge
  3. Start asking questions and experience the difference

Whether you're a developer looking for technical answers, a researcher exploring AI trends, or just curious about what all the hype is about — Grok 4.5 on Felo Search is worth trying.

The Bigger Picture​

Grok 4.5's release isn't just another model drop. It's a signal that the AI coding market is entering a new phase — one where price, token efficiency, and vertical integration (model + IDE + distribution) matter as much as raw benchmark scores.

SpaceXAI has the compute. Cursor has the developer data. Together, they've built something that's making even Claude and OpenAI users reconsider their subscriptions.

We think you should judge for yourself. Head to Felo Search and give Grok 4.5 a spin — on us, for 7 days.
