COSTAR prompting framework
COSTAR is a structured methodology that guides you thru crafting efficient prompts for FMs. By following its step-by-step strategy, you may design prompts tailor-made to generate the varieties of responses you want from the FM. The class of COSTAR lies in its versatility—it gives a strong basis for immediate engineering, whatever the particular approach or strategy you use. Whether or not you’re utilizing few-shot studying, chain-of-thought prompting, or one other technique (lined later on this submit), the COSTAR framework equips you with a scientific approach to formulate prompts that unlock the total potential of FMs.
COSTAR stands for the next:
- Context – Offering background data helps the FM perceive the particular state of affairs and supply related responses
- Goal – Clearly defining the duty directs the FM’s focus to satisfy that particular aim
- Fashion – Specifying the specified writing model, equivalent to emulating a well-known persona or skilled skilled, guides the FM to align its response along with your wants
- Tone – Setting the tone makes certain the response resonates with the required sentiment, whether or not or not it’s formal, humorous, or empathetic
- Viewers – Figuring out the meant viewers tailors the FM’s response to be acceptable and comprehensible for particular teams, equivalent to consultants or freshmen
- Response – Offering the response format, like a listing or JSON, makes certain the FM outputs within the required construction for downstream duties
By breaking down the immediate creation course of into distinct levels, COSTAR empowers you to methodically refine and optimize your prompts, ensuring each facet is fastidiously thought of and aligned along with your particular objectives. This stage of rigor and deliberation in the end interprets into extra correct, coherent, and useful outputs from the FM.
Chain-of-thought prompting
Chain-of-thought (CoT) prompting is an strategy that improves the reasoning talents of FMs by breaking down advanced questions or duties into smaller, extra manageable steps. It mimics how people motive and clear up issues by systematically breaking down the decision-making course of. With conventional prompting, a language mannequin makes an attempt to supply a remaining reply immediately primarily based on the immediate. Nonetheless, in lots of instances, this will likely result in suboptimal or incorrect responses, particularly for duties that require multistep reasoning or logical deductions.
CoT prompting addresses this situation by guiding the language mannequin to explicitly lay out its step-by-step thought course of, referred to as a reasoning chain, earlier than arriving on the remaining reply. This strategy makes the mannequin’s reasoning course of extra clear and interpretable. This method has been proven to considerably enhance efficiency on duties that require multistep reasoning, logical deductions, or advanced problem-solving. General, CoT prompting is a strong approach that makes use of the strengths of FMs whereas mitigating their weaknesses in advanced reasoning duties, in the end resulting in extra dependable and well-reasoned outputs.
Let’s have a look at some examples of CoT prompting with its totally different variants.
CoT with zero-shot prompting
The primary instance is a zero-shot CoT immediate. Zero-shot prompting is a way that doesn’t embrace a desired output instance within the preliminary immediate.
The next instance makes use of Anthropic’s Claude in Amazon Bedrock. XML tags are used to supply additional context within the immediate. Though Anthropic Claude can perceive the immediate in quite a lot of codecs, it was educated utilizing XML tags. On this case, there are sometimes higher high quality and latency outcomes if we use this tagging construction so as to add additional directions within the immediate. For extra data on learn how to present extra context or directions, check with the related documentation for the FM you’re utilizing.
You need to use Amazon Bedrock to ship Anthropic Claude Textual content Completions API or Anthropic Claude Messages API inference requests, as seen within the following examples. See the total documentation at Anthropic Claude fashions.
We enter the next immediate:
As you may see within the instance, the FM supplied reasoning utilizing the
CoT with few-shot prompting
Few-shot prompting is a way that features a desired output instance within the preliminary immediate. The next instance features a easy CoT pattern response to assist the mannequin reply the follow-up query. Few-shot prompting examples may be outlined in a immediate catalog or template, which is mentioned later on this submit.
The next is our customary few-shot immediate (not CoT prompting):
We get the next response:
Though this response is appropriate, we might wish to know the variety of goldfish and rainbow fish which might be left. Subsequently, we must be extra particular in how we wish to construction the output. We will do that by including a thought course of we would like the FM to reflect in our instance reply.
The next is our CoT immediate (few-shot):
We get the next appropriate response:
Self-consistency prompting
To additional enhance your CoT prompting talents, you may generate a number of responses which might be aggregated and choose the commonest output. This is called self-consistency prompting. Self-consistency prompting requires sampling a number of, various reasoning paths by few-shot CoT. It then makes use of the generations to pick out essentially the most constant reply. Self-consistency with CoT is confirmed to outperform customary CoT as a result of choosing from a number of responses normally results in a extra constant answer.
If there’s uncertainty within the response or if the outcomes disagree considerably, both a human or an overarching FM (see the immediate chaining part on this submit) can assessment every end result and choose essentially the most logical selection.

Tree of Ideas prompting
Tree of Ideas (ToT) prompting is a way used to enhance FM reasoning capabilities by breaking down bigger drawback statements right into a treelike format, the place every drawback is split into smaller subproblems. Consider this as a tree construction: the tree begins with a strong trunk (representing the primary subject) after which separates into smaller branches (smaller questions or matters).
This strategy permits the FMs to self-evaluate. The mannequin is prompted to motive by every subtopic and mix the options to reach on the remaining reply. The ToT outputs are then mixed with search algorithms, equivalent to breadth-first search (BFS) and depth-first search (DFS), which lets you traverse ahead and backward by every subject within the tree. In line with Tree of Ideas: Deliberate Drawback Fixing with Massive Language Fashions, ToT considerably outperforms different prompting strategies.
One technique of utilizing ToT is to ask the LMM to guage whether or not every thought within the tree is logical, potential, or not possible if you happen to’re fixing a posh drawback. It’s also possible to apply ToT prompting in different use instances. For instance, if you happen to ask an FM, “What are the consequences of local weather change?” you should utilize ToT to assist break this subject down into subtopics equivalent to “checklist the environmental results” and “checklist the social results.”
The next instance makes use of the ToT prompting approach to permit Claude 3 Sonnet to unravel the place the ball is hidden. The FM can take the ToT output (subproblems 1–5) and formulate a remaining reply.
We use the next immediate:
We get the next response:
Utilizing the ToT prompting approach, the FM has damaged down the issue of, “The place is the ball?” right into a set of subproblems which might be easier to reply. We sometimes see extra logical outcomes with this prompting strategy in comparison with a zero-shot direct query equivalent to, “The place is the ball?”
