Together AI Production Checklist

Overview

Together AI provides OpenAI-compatible inference across 100+ open-source models (Llama, Mixtral, Qwen, FLUX) plus fine-tuning and batch processing. A production integration routes completions, embeddings, or image generation through Together's API. Failures mean inference latency spikes, model availability gaps, or unexpected cost overruns from uncontrolled batch jobs.

Authentication & Secrets

• TOGETHER_API_KEY stored in secrets manager (not source code)
• API key restricted to production workspace
• Key rotation schedule documented (90-day cycle)
• Separate keys for dev/staging/prod environments
• Fine-tuning job tokens scoped separately from inference tokens

API Integration

• Production base URL configured (https://api.together.xyz/v1)
• Rate limit handling with exponential backoff
• Model IDs validated against client.models.list() before deployment
• Completion streaming implemented for real-time use cases
• Embedding batch size optimized (max 2048 inputs per request)
• Batch inference configured for non-real-time workloads (50% cost savings)
• Fallback model configured if primary model is unavailable

Error Handling & Resilience

• Circuit breaker configured for Together API outages
• Retry with backoff for 429/5xx responses
• Model-not-found errors caught before user-facing requests
• Token usage tracked per request to prevent budget overruns
• Fine-tuning job failure alerts configured
• Timeout handling for long-running generation requests (>30s)

Monitoring & Alerting

• API latency tracked per model and endpoint (chat, embeddings, images)
• Error rate alerts set (threshold: >5% over 5 minutes)
• Token consumption monitored against daily/monthly budget caps
• Model availability checked (Together status page integration)
• Batch job completion rate tracked
