What is Baseten?

Baseten is selling to the labs that build models, not just the developers who call them.

The catalog turns over constantly — DeepSeek V4 Pro 0813, Inkling and Inkling Small, Kimi K3, GLM 5.2 Fast in, and GLM 5.1, GLM 5, Kimi K2.5 and Nemotron Super 120B deprecated — all reachable through the same OpenAI-compatible endpoint with dedicated deployments for larger workloads. Two releases break that pattern. Baseten for Model Labs packages the serving stack as infrastructure a lab can adopt instead of building its own, and the Fast tier debuts with GLM 5.2 Fast: identical weights on dedicated capacity tuned for sustained per-user throughput. Workspace governance fills in alongside — org-scoped key administration, programmatic logs and metrics, and a GPU usage view for admins.

What is OpenRouter?

OpenRouter is turning the routing decision itself into the product.

Recent shipping splits in two. The routing layer keeps getting smarter — a rebuilt Auto router, live leaderboards for web-search configurations, guidance on measuring provider latency and throughput. Beside it sits Ori, a client-side line covering evals and harness configuration, plus a steady run of spend-governance material: shared org credit pools, per-key caps, per-member budgets, and Classifiers that tag every generation by department or task type.

Baseten is selling to the labs that build models, not just the developers who call them.

◆ Current state

The catalog turns over constantly — DeepSeek V4 Pro 0813, Inkling and Inkling Small, Kimi K3, GLM 5.2 Fast in, and GLM 5.1, GLM 5, Kimi K2.5 and Nemotron Super 120B deprecated — all reachable through the same OpenAI-compatible endpoint with dedicated deployments for larger workloads. Two releases break that pattern. Baseten for Model Labs packages the serving stack as infrastructure a lab can adopt instead of building its own, and the Fast tier debuts with GLM 5.2 Fast: identical weights on dedicated capacity tuned for sustained per-user throughput. Workspace governance fills in alongside — org-scoped key administration, programmatic logs and metrics, and a GPU usage view for admins.

◆ Where it's heading

Baseten is working both sides of the market at once. Toward developers, model choice is being commoditised into interchangeable catalog entries while serving characteristics become the thing that is actually priced. Toward labs, the pitch is that distribution and serving are someone else's problem. Those converge on the same position: whoever owns the endpoint owns the relationship, regardless of who trained the weights. The governance releases are the unglamorous prerequisite for the larger accounts that position requires.

◆ Prediction

Expect the Fast tier to expand beyond GLM 5.2 to the models agentic workloads lean on hardest, and the deprecation cadence to continue thinning older catalog entries as newer ones land.

OpenRouter is turning the routing decision itself into the product.

◆ Current state

Recent shipping splits in two. The routing layer keeps getting smarter — a rebuilt Auto router, live leaderboards for web-search configurations, guidance on measuring provider latency and throughput. Beside it sits Ori, a client-side line covering evals and harness configuration, plus a steady run of spend-governance material: shared org credit pools, per-key caps, per-member budgets, and Classifiers that tag every generation by department or task type.

◆ Where it's heading

The company is moving from 'one endpoint, many models' toward owning which model actually runs. Auto routing trained on aggregate user choices, evals that grade your own agent on your own prompts, and published benchmarks all make the routing call harder to reproduce with a raw provider key. The spend controls are the enterprise wrapper that lets that default survive contact with a finance team.

◆ Prediction

Expect the Auto router and Ori Eval to converge, with eval results feeding routing policy directly, and more first-party leaderboards published for request types beyond web search.
