You create a fine-tuning dedicated AI cluster to customize a foundational model with your custom training dat
a. How many unit hours are required for fine-tuning if the cluster is active for 10 hours?
Comprehensive and Detailed In-Depth Explanation=
In OCI, unit hours typically equal actual hours of cluster activity unless specified otherwise (e.g., per GPU scaling). For 10 hours of activity, it's 10 hours 1 unit/hour = 10 unit hours, but options suggest a multiplier (common in cloud pricing). Assuming a standard 2-unit/hour rate (e.g., for GPU clusters), it's 10 2 = 20 unit hours---Option C fits best. Options A, B, and D imply inconsistent rates (2.5, 4, 3).
: OCI 2025 Generative AI documentation likely specifies unit hour rates under DedicatedAI Cluster pricing.
In the context of generating text with a Large Language Model (LLM), what does the process of greedy decoding entail?
Comprehensive and Detailed In-Depth Explanation=
Greedy decoding selects the word with the highest probability at each step, aiming for locally optimal choices without considering future tokens. This makes Option C correct. Option A (random selection) describes sampling, not greedy decoding. Option B (position-based) isn't how greedy decoding works---it's probability-driven. Option D (weighted random) aligns with top-k or top-p sampling, not greedy. Greedy decoding is fast but can lack diversity.
: OCI 2025 Generative AI documentation likely explains greedy decoding under decoding strategies.
Which is NOT a typical use case for LangSmith Evaluators?
Comprehensive and Detailed In-Depth Explanation=
LangSmith Evaluators assess LLM outputs for qualities like coherence (A), factual accuracy (C), and bias/toxicity (D), aiding development and debugging. Aligning code readability (B) pertains to software engineering, not LLM evaluation, making it the odd one out---Option B is correct as NOT a use case. Options A, C, and D align with LangSmith's focus on text quality and ethics.
: OCI 2025 Generative AI documentation likely lists LangSmith Evaluator use cases under evaluation tools.
In which scenario is soft prompting especially appropriate compared to other training styles?
Comprehensive and Detailed In-Depth Explanation=
Soft prompting (e.g., prompt tuning) involves adding trainable parameters (soft prompts) to an LLM's input while keeping the model's weights frozen, adapting it to tasks without task-specific retraining. This is efficient when fine-tuning or large datasets aren't feasible, making Option C correct. Option A suits full fine-tuning, not soft prompting, which avoids extensive labeled data needs. Option B could apply, but domain adaptation often requires more than soft prompting (e.g., fine-tuning). Option D describes continued pretraining, not soft prompting. Soft prompting excels in low-resource customization.
: OCI 2025 Generative AI documentation likely discusses soft prompting under parameter-efficient methods.
What does the Loss metric indicate about a model's predictions?
Comprehensive and Detailed In-Depth Explanation=
Loss is a metric that quantifies the difference between a model's predictions and the actual target values, indicating how incorrect (or ''wrong'') the predictions are. Lower loss means better performance, making Option B correct. Option A is false---loss isn't about prediction count. Option C is incorrect---loss decreases as the model improves, not increases. Option D is wrong---loss measures overall error, not just correct predictions. Loss guides training optimization.
: OCI 2025 Generative AI documentation likely defines loss under model training and evaluation metrics.
