Prompts that actually work

Grok 4.5 is one of the most cost-efficient frontier models for coding — at $2/$6/M and 64.7% SWE-bench Pro, it handles debugging, code review, and refactoring at a fraction of the cost of Fable 5 or GPT-5.6 Sol. These prompts are optimised for Grok 4.5 via SuperGrok or the xAI API and take advantage of Grok's live X data access for tracking library updates and deprecations in real time.

Grok 4.5 with live X data access is uniquely positioned for financial research — it can pull real-time market sentiment, earnings reactions, and breaking news into financial analysis without manual research. At $2/$6/M via SuperGrok or the xAI API, it is significantly cheaper than GPT-5.6 Sol for high-volume financial queries. Note: these prompts are for research and analysis only — not financial advice.

Grok 4.5 with live X data access and 120 min/day Aurora voice on SuperGrok is uniquely positioned for real-time productivity workflows — morning briefings on current events, meeting prep from social media signals, competitor monitoring, and fast research tasks. These prompts cover daily workflow automation, news monitoring, task prioritisation, and voice-mode productivity sessions for SuperGrok and SuperGrok Heavy subscribers.

Grok 4.5 brings a unique advantage to SEO work: real-time X data access means you can research what people are actually discussing and searching for right now — not last month. These prompts cover keyword research, meta tag writing, title optimisation, and content gap analysis, all taking advantage of Grok's ability to surface live search intent signals from social discourse.

Grok 4.5's direct, no-filler writing style makes it particularly effective for fast-turnaround content — news summaries, social media posts, product descriptions, and opinion pieces. Its live X data access means it can incorporate current events and trending topics into written content without manual research. These prompts are optimised for SuperGrok and grok.com.

Grok Voice uses the Aurora model for natural real-time conversation with live X data access. Unlike text prompts, voice prompts need to be short, natural-sounding, and designed for spoken dialogue. These are optimised conversation starters for Grok Voice on iOS and Android — for SuperGrok (120 min/day) and SuperGrok Heavy (480 min/day) subscribers. Free tier gets 15 min/day.

Grok Voice Think Fast 2.0 ($0.08/min, AA agentic #1 at 56.5%, STS #2 at 82.9%) became the default on August 5, 2026. Key prompt guidance from ExplainX.ai and xAI's official docs: shorten system prompts, drop GPT-era workaround strings, and set reasoning.effort to "none" if you want less parallel thinking (it defaults to "high"). Most prompts from v1.0 carry over without changes — but regression test on your specific call type before production. Pin grok-voice-think-fast-2.0 in production; let grok-voice-latest float only in staging. Tool calling, web search, X search, file search, and remote MCP tools are all supported. These prompts are optimised for the Grok Voice API (model: grok-voice-think-fast-2.0) and the Voice Agent Builder.

Kimi K3 ranks #1 globally on Design Arena frontend coding (1679 Elo) and #1 on SWE Marathon (42.0%) — making it the strongest available model for frontend development and long-horizon agentic coding tasks. At $3/$15/M with 1M context on Allegretto+ tier, it offers the best price-to-coding-capability ratio of any frontier model. These prompts are optimised for Kimi Code CLI, the Kimi API, and kimi.com on Allegretto+ or Vivace tiers.

Kimi K3 leads the SWE Marathon agentic coding benchmark at 42.0% and tops the Frontend Code Design Arena at 1679 Elo — the highest coding-specific rankings of any model in July 2026. At $3/$15/M ($0.30/M cached) with 1M context, K3 can ingest entire codebases in a single session. Open weights are live from July 27, 2026 at huggingface.co/moonshotai under Modified MIT license. Important: independent testing found a 51% hallucination rate not disclosed in Moonshot's benchmarks — test on factual/retrieval tasks before production deployment. These prompts are optimised for kimi.com Allegretto+/Vivace tiers, the Kimi API, and self-hosted K3 deployments.

Kimi K3's 1M context window on Allegretto+ tier makes it one of the strongest research models available — it can ingest entire research papers, technical documentation sets, and large code repositories in a single session. At $0.30/M cached input, repeated context (like a standing research brief or knowledge base) becomes extremely cost-efficient. These prompts are optimised for kimi.com on Allegretto+ or Vivace tiers and the Kimi API.

Kimi K3 on Allegretto+ tier offers 1M context for writing tasks that require deep document awareness — editing a long manuscript, maintaining style consistency across a large content set, or rewriting with full context of everything written before. At $0.30/M cached input, repeatedly referencing a style guide or brand voice document costs almost nothing. These prompts are optimised for kimi.com on Allegretto+ and the Kimi API.

Kimi K3 with 1M context on Allegretto+ is exceptional for long-form writing tasks — the model can hold an entire book manuscript, legal document, or content strategy in context while writing new sections. At $3/$15/M ($0.30/M cached), repeated long-context writing sessions are cost-efficient. These prompts are optimised for kimi.com on Allegretto+ or Vivace tiers.

Qwen3.7-Max at $2.50/$7.50/M scored 80.4% on SWE-bench Verified and was the highest-placed Chinese model on the Artificial Analysis Intelligence Index at launch in May 2026. Qwen3.8-Max-Preview (July 19, 2026) adds multimodal capability and a 2.4T parameter scale, but benchmark results are not yet published — test on your own workload via the Token Plan preview. Qwen models support tool calling, code execution, long-context document analysis, and multi-turn agent sessions. These prompts are optimised for Qwen3.7-Max via the Alibaba Cloud API and Qwen3.8-Max-Preview via the Token Plan.

ChatGPT is fast, flexible, and excellent for coding tasks ranging from quick scripts to full feature implementation. These prompts are optimized for GPT-4o and work well across ChatGPT Plus and the API.

Claude is exceptionally good at SEO tasks that require structured thinking — keyword clustering, meta tag writing, content briefs, and title optimization. These prompts are built for SEO professionals and content teams.

ChatGPT is the most versatile writing assistant available in 2026. These prompts cover blog writing, copywriting, emails, social media, and creative writing — all tested on GPT-4o for quality output.

Grok excels at research tasks that require real-time information, current events, and fast-moving topics. These prompts are optimized for Grok 3 and take advantage of its live data access and direct response style.
