The editorial take
Choose OpenRouter if you need to switch among many model providers or compare proprietary and open models without separate accounts. Choose Together AI if your workload is centered on open-source model inference, fine-tuning, or direct infrastructure from a single AI cloud.
OpenRouter - Pros & Cons
Pros
- ✓One API key and one bill for hundreds of models across dozens of providers
- ✓Automatic fallback keeps apps running when a provider throttles or fails
- ✓OpenAI-compatible schema drops into most SDKs and agent frameworks unchanged
- ✓BYOK lets you keep your provider contracts/rate limits while using the gateway
- ✓Provider preference controls (price/latency/ZDR) give real routing flexibility
Cons
- ✗Extra network hop adds a small amount of latency versus calling providers directly
- ✗Single point of failure — an OpenRouter outage takes down every model at once
- ✗Free-tier models are rate-limited and rotate, so not suitable for production
- ✗BYOK still incurs a 5% fee after 1M requests/month, on top of provider billing
- ✗Enterprise controls (SSO, VPC peering, audit exports) are lighter than dedicated gateways like Portkey
Together AI - Pros & Cons
Pros
- ✓Cheaper per token than closed-model APIs for equivalent tasks — Llama 3.3 70B at ~$0.88/M is a real cost delta
- ✓Broad catalog covers most open models teams actually consider (Llama, DeepSeek, Qwen, Mistral, Kimi)
- ✓Three deployment tiers (serverless, dedicated, cluster) let you graduate without moving off the platform
- ✓Full-parameter and LoRA fine-tuning available with your dataset — a rare combination at this price
- ✓HIPAA-eligible and SOC 2 Type II environments make enterprise deals possible
Cons
- ✗Frontier reasoning still lags Claude, GPT, and Gemini for the hardest tasks; open models close but rarely lead
- ✗Serverless cold starts and shared-tenant latency vary — high-QPS production usually needs dedicated endpoints
- ✗Pricing per model shifts frequently as new SKUs launch; long-term budgeting requires occasional re-costing
- ✗Dedicated endpoints and clusters require some capacity planning — not fire-and-forget like serverless
