Speculative decoding has been around for a while. The idea: a small "draft" model predicts tokens cheaply, a large "verifier" model accepts or rejects them in batches. When acceptance rates are high, you get near-large-model quality at near-small-model speed.
The problem has always been static draft models. They work great on benchmarks, then degrade on your specific code, your naming conventions, your framework patterns. ATLAS fixes this.
Together AI's ATLAS (AdapTive-LeArning Speculator System) is the first speculative decoding system that dynamically adapts to workload patterns at runtime. No manual tuning. During a coding session, it specializes for the specific files being edited. The longer you work, the higher the acceptance rate climbs, the faster inference gets. Together claims 400% speedup on sustained coding sessions.
Available now on dedicated endpoints at no additional cost to 800K+ developers. That last part matters. This isn't a research paper or a waitlist. It's deployed.
For anyone running inference-heavy workflows (and if you're using coding agents, you are), this is free performance. The architecture is elegant: the system observes your workload's token distribution, adjusts the draft model's prediction biases toward patterns it's seeing repeatedly, and acceptance rates compound. Your codebase has naming patterns, import structures, common idioms. ATLAS learns them in real-time.
I'd combine this with the model routing pattern from story #5. Route complex reasoning to frontier, route everything else to local or Together endpoints with ATLAS enabled. Stack the savings.
