What is Baseten?

Baseten ends the free launch of elephant-1 and mammoth-1 and adds per-replica metrics.

Baseten's newest entries are commercial and operational. The elephant-1 and mammoth-1 classification models, launched free on October 21, moved to paid usage on Model APIs from October 27, and workspaces can now compare CPU, GPU and memory per replica to find outliers that aggregate graphs hide. The week before was mostly security: API keys unused for 30 days are revoked automatically, auth errors switch from 403 to 401 on October 28, and users were told to upgrade CLIs after the eMudhra CA compromise.

What is KServe?

KServe v0.21.0 ships as the GA release of a cycle that turned the platform into a production LLM inference layer.

KServe's last two major release cycles (v0.19.0, v0.20.0, now v0.21.0) delivered a comprehensive LLM serving rework: native support for OpenAI Completions, Responses API, and Anthropic Messages API; KV cache offloading for CPU tiering; traffic splitting for controlled LLM deployments; Managed DRA (Kubernetes Dynamic Resource Allocation) for GPU resource management; vLLM as a first-class runtime; LoRA adapter affinity scoring; confidential model serving; and autoscaling via KEDA and HPA. The LLMInferenceService (llmisvc) is now the platform's primary development surface, not the classic InferenceService.

Baseten ends the free launch of elephant-1 and mammoth-1 and adds per-replica metrics.

◆ Current state

Baseten's newest entries are commercial and operational. The elephant-1 and mammoth-1 classification models, launched free on October 21, moved to paid usage on Model APIs from October 27, and workspaces can now compare CPU, GPU and memory per replica to find outliers that aggregate graphs hide. The week before was mostly security: API keys unused for 30 days are revoked automatically, auth errors switch from 403 to 401 on October 28, and users were told to upgrade CLIs after the eMudhra CA compromise.

◆ Where it's heading

Baseten keeps adding models to Model APIs on a free-then-paid launch pattern, while building out observability for dedicated deployments: GPU temperature and utilization a week ago, per-replica breakdowns now. The security tightening of late October appears to have settled into defaults.

◆ Prediction

Expect further Model API additions following the same free launch window before paid usage, and more per-replica or per-worker debugging tools for dedicated deployments.

5.0

KServe v0.21.0 ships as the GA release of a cycle that turned the platform into a production LLM inference layer.

◆ Current state

KServe's last two major release cycles (v0.19.0, v0.20.0, now v0.21.0) delivered a comprehensive LLM serving rework: native support for OpenAI Completions, Responses API, and Anthropic Messages API; KV cache offloading for CPU tiering; traffic splitting for controlled LLM deployments; Managed DRA (Kubernetes Dynamic Resource Allocation) for GPU resource management; vLLM as a first-class runtime; LoRA adapter affinity scoring; confidential model serving; and autoscaling via KEDA and HPA. The LLMInferenceService (llmisvc) is now the platform's primary development surface, not the classic InferenceService.

◆ Where it's heading

KServe is repositioning as the Kubernetes-native LLM inference platform for enterprise, not just a generic ML serving abstraction. The prefill/decode disaggregation work (llm-d integration), KV cache tiering, distributed tracing, and multi-API protocol support (OpenAI, Anthropic) all target production LLM workloads at scale. Confidential model serving and Managed DRA integration signal intent to serve regulated environments where GPU resource isolation and data protection are requirements. The llmisvc trajectory points toward multi-model routing behind a single endpoint and increasingly sophisticated scheduling.

◆ Prediction

The v0.21.0 release cycle likely consolidates the llmisvc API into a stable surface. The next major release will probably ship autoscaling policies based on KV cache utilization rather than request count alone, and extend multi-model routing to cover model versioning and A/B deployments.
