Pick the right LLM model for an Output SDK prompt file.

Tokens, turns and time describe resource use, not a dollar price.
One of 7 test cases the skill fixed. Same model, same prompt, with and without the skill.
We need to run bulk offline token classification across millions of archive records where spend dominates completely and quality requirements are soft. Sibling prompts use `provider: openai`. Which model tier suffix should be selected?
| Checked | Without skill | With skill |
|---|---|---|
| The selected OpenAI model string ends with -nano. | Missed | Passed |
The instructions your model reads when the skill loads.
This skill is the single source of truth for model selection across Output SDK skills and agents. Other skills link here instead of pinning specific model IDs, because model rosters drift faster than docs.
We run this at skill-load time to fetch the 10 most recently released models per provider from the Vercel AI Gateway:
output=$(curl -fsS https://ai-gateway.vercel.sh/v1/models 2>/dev/null | jq '
.data as $models
| {
anthropic: ([ $models[] | select(.id | startswith("anthropic/")) ] | sort_by(.released) | reverse | .[0:10]),
openai: ([ $models[] | select(.id | startswith("openai/")) ] | sort_by(.released) | reverse | .[0:10]),
google: ([ $models[] | select(.id | startswith("google/")) ] | sort_by(.released) | reverse | .[0:10])
}
' 2>/dev/null)
if [ -n "$output" ]; then printf '%s\n' "$output"; else echo "(snapshot unavailable)"; fi
output=$(curl -fsS https://ai-gateway.vercel.sh/v1/models 2>/dev/null | jq '
.data as $models
| {
anthropic: ([ $models[] | select(.id | startswith("anthropic/")) ] | sort_by(.released) | reverse | .[0:10]),
openai: ([ $models[] | select(.id | startswith("openai/")) ] | sort_by(.released) | reverse | .[0:10]),

}
' 2>/dev/null)
if [ -n "$output" ]; then printf '%s\n' "$output"; else echo "(snapshot unavailable)"; fi
If the block above is empty, the script didn't execute automatically — likely because part of it (jq, curl, or network access) is missing. Query and filter the snapshot yourself before continuing.
