Lesson 20 of 25
The Strategic Use of Temperature
Temperature is the setting that controls how adventurous a model's word choices are: low makes it predictable and literal, high makes it surprising and inventive. The important thing to know is that you cannot touch it in the ChatGPT, Claude or Gemini apps - there is no slider. It is an API setting, or one you adjust in Google AI Studio. In the apps you get the same effect through wording: "stick strictly to the text, add nothing" pulls the output one way, "be surprising, give me unexpected angles" pulls it the other.
There is no temperature setting here at all, and the question is close to moot: an answer engine is built to report what sources say, which is low-temperature behaviour by construction. For the factual example that makes it a natural fit - and it goes further than the others, because it can tell you what else was reported about the same event rather than only summarising your copy. For the creative example it is the wrong tool, and for the poem it does the research half while another tool does the imaginative half.
- No temperature setting, and no wording changes it.
- Low-temperature by construction - the natural fit for factual work.
- It is faithful to its sources, not to your pasted text.
- Do not expect creative looseness at any wording.
- Use it to check what else was reported on the same event.

**Goal: a precise, factual summary of a news article.** This is the natural fit for an answer engine - it has no temperature setting and does not need one, because reporting what sources say *is* low-temperature behaviour. One caution: it is faithful to the sources it finds, not to the article you hand it, so if you need a summary bounded strictly to one document, do that in Claude, ChatGPT or Gemini. What this tool adds is the comparison. I am looking at a report in The Hindu about [EVENT]. Published [DATE]. 1. What are the key facts of this event as reported? Give them as a numbered list, each with the outlet and date it came from. 2. Which outlets reported it, and where do their accounts differ on facts - figures, timings, attributions, who said what? Name the differences explicitly. This is what a single-source summary cannot give me and it is the reason to ask here. 3. Which claims are attributed to officials or spokespeople rather than independently confirmed? Separate these from the rest. A reported claim and an established fact are different things and most coverage blurs them. 4. What is the primary source - a government order, a court judgment, a company filing, a press release? Link it directly. I would rather read the document than anyone's summary of it. 5. What has been reported since [DATE]? Anything corrected, retracted or updated. 6. What remains unreported or unresolved? Name the open questions rather than filling them in. For every fact: the source and the date. No interpretation, no analysis of what it means, no prediction of what follows - and if the only available sources are themselves opinion pieces, say so rather than extracting facts from argument. Where sources conflict, present the conflict. Do not resolve it by picking the most common version.

**Goal: brainstorm creative names for a new food delivery service in Hyderabad.** Wrong tool, and this is the clearest illustration of the chapter's point. There is no temperature setting here and no wording raises it - tell an answer engine to be wild and surprising and it will return sourced sobriety with citations, because that is what it is for. Generate the names in ChatGPT, Claude or Gemini. What this tool does better than any of them is the research either side of that. Run this first: 1. Which food delivery and quick-commerce brands currently operate in Hyderabad? List them with their names and cite your sources. Include the small and regional ones, not just the national players. 2. Looking at those names together, what naming conventions dominate - which words, which languages, which constructions recur? State the pattern explicitly. That becomes my ban list in the next tool, which is worth more than any instruction to be creative. 3. What is reported about the Hyderabad food delivery market - how competitive it is, whether speed is already an established claim, and whether anyone owns it? Cite reports with dates. If three brands already promise ten-minute delivery, my positioning is the problem rather than my name. 4. How do I actually check whether a brand name is available in India? Which trade mark classes cover food delivery, how to search the IP India register, and what else is required to trade - FSSAI, Shops and Establishments in Telangana. Cite the official process. 5. What naming disputes or forced rebrands have Indian consumer brands been through? Cite the cases, so I know what the mistake costs. 6. What is documented about brand names that blend English with Indian languages - any research or industry commentary on how they perform? Use Academic focus where it exists and say plainly if there is little published. Cite everything with dates. Where you only find aggregators and listicles, say so rather than dressing them up. Then generate elsewhere with answer 2 as the ban list, and come back here with your final three for the checks in answer 4.

**Goal: both a factual summary and a creative interpretation of a poem.** Half of this belongs here and half does not, which makes it a good illustration. There is no temperature setting on this tool, and the imaginative half of the task cannot be asked for at any wording - what comes back will be sourced criticism rather than your own reading. Do Task 2 in Claude, ChatGPT or Gemini. What this tool does well is everything you would want to know before interpreting. On "The Tyger" by William Blake: 1. What is the established factual record - when it was written and published, which collection, and what is known about its composition and the accompanying plate? Cite scholarly sources with dates. Strictly what is documented, not what is inferred. 2. What are the major critical interpretations of the poem? For each, name the critic or school and cite the work. I want the map of existing readings before I form my own - and specifically so that I know when a reading I think is mine is actually a well-worn position. 3. Which readings are currently dominant in scholarship, and which have fallen out of favour? Cite recent criticism. Use Academic focus. 4. What is documented about Blake's own religious and political views at the time, and how far do scholars disagree about how much they should bear on the poem? Cite the disagreement rather than resolving it. This is exactly where a non-sourced tool will give you a confident answer to a contested question. 5. What is the relationship between this poem and "The Lamb", as scholars describe it? Cite the criticism. 6. Where does the surviving manuscript evidence show Blake revised the poem, and what changed? Cite the scholarship. The revisions are the most concrete evidence available about intent and they are routinely left out of general accounts. Cite everything. Distinguish documented fact from critical interpretation throughout - the two get fused in most writing about this poem and separating them is the single most useful thing on this list. Then take it elsewhere for the two tasks: the literal summary from the poem itself, and the three imaginative readings. Use answer 2 to check that at least one of your three is genuinely new.
