prompt = f"Write a product description for {item['product']} with these features: {features}"
req = {
"key" : item["product" ],
"request" : {
"contents" : [{"parts" : [{"text" : prompt}]}]
}
}
f.write(json.dumps(req) + "\n" )
EOF
node scripts/create_batch.js product-descriptions.jsonl
node scripts/check_status.js <job-name> --wait
node scripts/get_results.js <job-name> --output results.jsonl
Best for: Product descriptions, dataset enrichment, bulk analysis
Workflow 4: Email Campaign Generation
python3 << 'EOF'
import json
customers = [
{"name" : "Alice" , "product" : "premium plan" },
{"name" : "Bob" , "product" : "basic plan" },
]
with open("emails.jsonl" , "w" ) as f:
for cust in customers:
prompt = f"Write a personalized email to {cust['name']} about upgrading to our {cust['product']}"
req = {
"key" : f"email-{cust['name'].lower()}" ,
"request" : {
"contents" : [{"parts" : [{"text" : prompt}]}]
}
}
f.write(json.dumps(req) + "\n" )
EOF
node scripts/create_batch.js emails.jsonl --name "email-campaign"
node scripts/check_status.js <job-name> --wait
node scripts/get_results.js <job-name> --output email-results.jsonl

Workflow 5: Async Job Monitoring
node scripts/create_batch.js large-batch.jsonl --name "big-job"
while true ; do
node scripts/check_status.js <job-name>
sleep 60
done
node scripts/get_results.js <job-name> --output final-results.jsonl

Parameters Reference
JSONL Format Each line is a separate JSON object:
{
"key" : "unique-identifier" ,
"request" : {
"contents" : [
{
"parts" : [
{
"text" : "Your prompt here"
}
]
}
]
}
}
Model Selection Model Best For Cost Speed gemini-3-flash-previewGeneral bulk processing Lowest Fast gemini-3-pro-previewComplex reasoning tasks Medium Medium gemini-2.5-flashStable, reliable Low Fast gemini-2.5-proCode/math/STEM Medium Slow
Job States State Description JOB_STATE_PENDINGJob queued, waiting to start JOB_STATE_RUNNINGJob actively processing JOB_STATE_SUCCEEDEDJob completed successfully JOB_STATE_FAILEDJob failed (check error message) JOB_STATE_CANCELLEDJob was cancelled JOB_STATE_EXPIREDJob timed out
Size Limits Method Max Size Best For File upload Unlimited Large batches (recommended) Inline requests <20MB Small batches
Output Interpretation
Results JSONL {
"key" : "your-identifier" ,
"response" : {
"text" : "Generated content here..."
}
}
Error Handling
Failed requests appear in results with error information
Check for error field in response
Partial failures don't stop entire job
Result Access
Use --output to save to file
Script prints preview of results
Parse JSONL line by line for processing
Common Issues
"google-genai not installed" npm install @google/genai@latest dotenv@latest
"JSONL file not found"
Verify file path is correct
Check file extension is .jsonl (not .json)
Use absolute paths if relative paths fail
"Invalid JSONL format"
Each line must be valid JSON
No trailing commas between objects
Check for syntax errors in JSON
Use JSON validator if unsure
"Job failed"
Check error message in status
Verify request format is correct
Check model availability
Review API quota limits
"No results found"
Ensure job state is JOB_STATE_SUCCEEDED
Wait for job completion before retrieving
Check job status first with check_status.js
"Processing stuck in RUNNING state"
Large jobs can take hours
Use --wait flag for automated polling
Check job size and model choice
Contact support if stuck >24 hours
Best Practices
JSONL Creation
Use unique keys for each request
Validate JSON before uploading
Test with small batch first (5-10 requests)
Include error handling in your scripts
Job Management
Use descriptive display names (--name)
Save job names for tracking
Monitor status before retrieving results
Keep backup of original JSONL file
Performance Optimization
Use flash models for cost efficiency
Batch as many requests as possible
File upload preferred over inline
Process during off-peak hours if timing sensitive
Error Handling
Check for failed requests in results
Retry failed requests individually
Log job names for audit trails
Validate output format before use
Cost Management
Batch API is 50%+ cheaper than real-time
Use flash models when possible
Monitor token usage
Process in chunks if quota limited
