Choose an AI model by testing it on the work you actually need done—not by assuming that a larger model or higher provider tier will be better. Set a minimum quality bar, compare candidates on representative examples, and weigh their results against response time and cost at your expected usage. A smaller, faster model is a good starting point for routine or high-volume tasks; move to a more capable option when tests expose a meaningful gap.
Start with the job, not the model name
Before comparing models, describe the workflow in concrete terms: what goes in, what should come out, who will use the result, and what errors would matter. “Summarize documents” is too broad to evaluate. Specify the document types, the required summary format, whether key facts must be cited or preserved, and what counts as an unacceptable omission.
Set a pass threshold before seeing the results. For a low-stakes brainstorming task, usefulness may be enough. For consequential work, define which errors are unacceptable and where a person must review the output. A model that is impressive on average can still be unsuitable if it fails on a rare but costly case.

Build a representative test set
Collect realistic prompts and inputs from the workflow, with permission and appropriate safeguards for sensitive data. Include ordinary examples as well as difficult cases: ambiguous instructions, unusual formats, incomplete input, and edge cases that have caused problems before. A handful of polished demonstration prompts is not enough to show how a model will behave in everyday use.

Keep the examples consistent across candidates. Where practical, reserve some examples for evaluation rather than using every case to tune the prompt. This helps reveal whether an improvement generalizes beyond the examples used to make it.
Choose a sensible starting point
For routine, frequent, or time-sensitive tasks
Start by trialing an efficient, lower-cost candidate and see whether it clears the quality bar. If it succeeds reliably, using a more capable model may add expense and delay without improving the outcome enough to matter.
For demanding or accuracy-critical tasks
Begin with a stronger candidate when the work requires nuanced reasoning, difficult synthesis, or accuracy that outweighs cost. Its results can establish a capability baseline. Then test whether a less costly option, better instructions, or additional context can meet the same threshold.

These are starting strategies, not rankings. OpenAI’s model-selection guidance recommends experimenting with models and reasoning settings while considering the workflow’s frequency, turnaround time, and intended use. Anthropic likewise describes both efficiency-first and capability-first approaches in its model-selection guide. Those pages are providers’ guidance, not independent head-to-head tests across vendors.
Compare candidates on the same cases
Run the same inputs through each candidate, with the same task instructions and relevant context. Score what matters for the actual workflow rather than relying on a generic benchmark or a quick impression.
- Task success and error severity: Did the output meet the acceptance criteria, and how costly would any error be?
- Instruction-following and quality: Did it use the required format, include the necessary details, and avoid unsupported additions?
- Edge cases: Did performance hold up on unusual, ambiguous, or incomplete inputs?
- Usability: Could the intended user act on the result without extensive correction?
- Required capabilities: Does the workflow need tool use, image or audio input, or another feature that a candidate must support?
Human reviewers can score outputs against a shared rubric. For a fair comparison, reviewers can assess anonymized outputs without knowing which model produced each one. Automated model graders may help with larger batches, but check them against human judgments; control for position and verbosity bias so a longer or first-listed answer does not win just for presentation.

Ideal for gaming, video editing, and multitasking, it provides expansive and crisp multi-display support.
Include speed and total cost in the decision
Record quality alongside response time and the cost of processing the expected inputs and outputs. Compare candidates at realistic prompt and response lengths, then estimate how often the workflow will run. A small per-request cost difference can become material at high volume; a slower response can also undermine an otherwise strong result if users need an immediate answer.
OpenAI’s latency optimization documentation says model size is the main factor influencing inference speed: smaller models usually run faster and cheaper, and can outperform larger ones when used correctly. That is qualified guidance, not a guarantee for every task or model. OpenAI also suggests detailed prompts, few-shot examples, and fine-tuning or distillation as ways to help smaller models perform well.
Check providers’ current prices and rate limits before making a purchasing decision. Offerings and terms can change, so a cost estimate based on an old price or usage limit may not reflect the real operating cost.

Improve the workflow before upgrading
If a candidate misses the bar, first inspect the failure. The problem may be an unclear instruction, missing context, an output format the prompt did not specify, or a task that should be split into smaller steps. Fixing those issues can be more effective than immediately moving to a larger model.
Then rerun the same evaluation set. If important cases still fail, try a more capable candidate or adjust supported reasoning settings and features. Keep the acceptance threshold fixed while testing so that a change in scoring does not make a weak result appear successful.

Model behavior is not fixed. OpenAI notes that outputs are non-deterministic and behavior can change between snapshots and model families in its model optimization guidance. Re-run relevant tests after changing a model, snapshot, prompt, provider, or feature setting, and periodically when the workflow is important enough that drift could cause harm.

Model size can offer a useful clue about speed and capability, but it cannot answer whether a model is right for a particular workflow. A 2022 example makes the distinction clear: in “Training Compute-Optimal Large Language Models,” Jordan Hoffmann and co-authors reported that the 70-billion-parameter Chinchilla model achieved 67.5% average accuracy on MMLU and exceeded Gopher by more than seven percentage points on that benchmark. The paper also reported that Chinchilla outperformed several larger models on a range of downstream evaluations. The authors trained more than 400 models, ranging from 70 million to over 16 billion parameters. These are historical findings from a specific 2022 study—not evidence that any current smaller model will beat any current larger one.
Google Cloud’s model-selection article also identifies factors such as performance, latency, cost, customization, data, skills, and compute. Treat that, like other providers’ selection advice, as a useful checklist rather than an independent ranking.
