Together AI reveals production-tested techniques cutting inference latency by 50-100ms while reducing per-token costs up to 5x through quantization and smart decoding.
Running AI models in production just got cheaper. Together AI published a detailed breakdown of optimization techniques that their enterprise clients use to slash inference costs by up to 5x while simultaneously cutting response times—a combination that seemed impossible just two years ago.
The Real Bottleneck Isn’t Your Model
Most teams blame slow AI responses on model size. They’re wrong.
According to Together AI’s production data, the actual culprits are memory stalls, inefficient kernel scheduling, and GPUs sitting idle while waiting on data transfers. Their benchmarks across Llama, Qwen, Mistral, and DeepSeek model families show that fixing these pipeline issues—not buying more hardware—delivers the biggest gains.
“Your GPU spends a lot of time doing nothing and just… waiting,” the company noted, pointing to unbalanced expert routing in Mixture-of-Experts layers and prefill paths that choke on long prompts.
Quantization Delivers 20-40% Throughput Gains
Dropping model precision from FP16 to FP8 or FP4 remains the fastest path to cheaper inference. Together AI reports 20-40% throughput improvements in production deployments without measurable quality degradation when done properly.
The math works out favorably: lighter memory footprint means larger batch sizes on the same GPU, which means more tokens processed per dollar spent.
Knowledge distillation offers even steeper savings. DeepSeek-R1’s distilled variants—smaller models trained to mimic the full-size version—deliver what Together AI calls “2-5x lower cost at similar quality bands” for coding assistants, chat applications, and high-volume enterprise workloads.
Geography Matters More Than You Think
Sometimes the fix is embarrassingly simple. Deploying a lightweight proxy in the same region as your inference cluster can shave 50-100ms off time-to-first-token by eliminating network round trips before generation even starts.
This aligns with broader industry momentum toward edge AI deployment. As InfoWorld reported on January 19, local inference is gaining traction precisely because it sidesteps the latency penalty of distant data centers while improving data privacy.
Decoding Tricks That Actually Work
Multi-token prediction (MTP) and speculative decoding represent the low-hanging fruit for teams already running optimized models. MTP predicts multiple tokens simultaneously, while speculative decoding uses a small “draft” model to accelerate generation for predictable workloads.
Together AI claims 20-50% faster decoding when these techniques are properly tuned. Their adaptive speculator system, ATLAS, customizes drafting strategies based on specific traffic patterns rather than using fixed approaches.
Hardware Selection Still Matters
NVIDIA’s Blackwell GPUs and Grace Blackwell (GB200) systems offer meaningful per-token throughput improvements, particularly for workloads with high concurrency or long context windows. But hardware alone won’t save you—tensor parallelism and expert parallelism strategies determine whether you actually capture those gains.
For teams processing billions of tokens daily, the combination of next-gen hardware with intelligent model distribution across devices produces measurable cost-per-token reductions.
What This Means for AI Builders
The playbook is straightforward: measure your baseline metrics (time-to-first-token, decode tokens per second, GPU utilization), then systematically attack the bottlenecks. Deploy regional proxies. Enable adaptive batching. Turn on speculative decoding. Dynamically shift GPU capacity between endpoints as traffic fluctuates.
Companies like Cursor and Decagon are already running this playbook to deliver sub-500ms responses without proportionally scaling their GPU bills. The techniques aren’t exotic—they’re just underutilized.
