What Grok is good at
Grok's personality is the first thing people notice: direct, brisk, and happy to give an opinion when asked for one. That makes it a good sparring partner for ideas and a quick way to get a straight answer without three paragraphs of preamble.
Its other strength is the present tense. Turn on Search and Grok pulls in real-time results from the web and from X, which suits questions about what people are saying, how a story is developing, or what changed today. Grok 4.3 accepts very long prompts too, up to a million tokens on the LazySusan API, so a long transcript or log file fits in one go.
For code there is Grok Build, a version tuned for programming. And the Image switch in the composer creates pictures with Grok Imagine without leaving the chat, which is handy for a quick visual to go with a post.

Chat costs are for a message of about 300 characters; you pay for what each reply uses. A typical Grok 4.3 reply is 6 tokens and Grok 4.7 11 tokens. Live search adds a little to each message that uses it.
Every plan includes Grok. Starter is $8 a month with 1,000 tokens; unused tokens roll over while you're subscribed. Compare plans.
prompts
Prompts to try with Grok
// live pulse
With Search on: what are people on X saying about today's interest rate decision? Summarise the main camps and link a few representative posts.
// straight answer
Give me your honest take: is it worth learning Rust in 2026 if I mainly write Python data pipelines? Keep it to five sentences.
// code
This Python function times out on large inputs. Explain why and rewrite it to run in linear time.
// long input
Here is the full server log from last night. Find the first error that caused the cascade and explain the chain of events.
// image
With Image on: a retro travel poster for a fictional Martian ski resort, bold flat colours.
tips
Getting better results
- 01Ask Grok for an opinion when you want one. It is more willing than most models to commit to a view, which is useful for decisions and less useful for neutral summaries.
- 02Turn on Search for anything time-sensitive. Without it, Grok answers from its training data, which won't know about this morning.
- 03Grok Auto sends code questions to Grok Build, at about 5 tokens a reply. If you're doing a long coding session, select Grok Build directly to keep it there.
- 04Grok Imagine images from the chat are about 24 tokens each, and you can ask for several at once.
alternatives
When to pick a different tool
- Perplexity if you need every claim backed by a numbered source rather than a quick take.
- ChatGPT if you want a measured, structured answer for planning or writing.
- Claude if the task is a long document or a careful piece of writing.
- DeepSeek if you want low-cost reasoning for maths or logic and don't need live search.
