Groq is climbing off raw inference: hosted tools and MCP connectors now sit above the chips.
GroqCloud's changelog splits three ways: model availability (MiniMax M2.5, Qwen3-VL for enterprise, GPT-OSS variants), speech work consolidating on Orpheus after the PlayAI deprecation, and a newer line of server-side capabilities — browser search as a built-in tool, and MCP connectors for Google Workspace. SDK releases are maintenance-grade following December 2025's 1.0 GA. Cadence has thinned since Q1, with the most recent captured entries dating to April.
Knock is hardening for enterprise buyers while its agent takes over the analysis work.
Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.

The interesting movement is Groq offering things that execute rather than only generate: tools the model can call inside Groq's own runtime, and pre-built OAuth connectors to business applications. That is a bid to be the place agents run, not merely the fastest token endpoint, and it competes with the same agent-runtime pitch Bedrock and OpenAI's Responses API make. Speed remains the underlying claim, but the surface being sold is moving up the stack.
Expect the connector catalog to widen beyond Google Workspace and more built-in tools to reach the general model lineup rather than only GPT-OSS.

Two arcs run in parallel. The infrastructure lane is buying enterprise credibility — roles, passkeys, audit-grade permissions — the checklist items that decide procurement rather than daily use. The data lane keeps widening what can trigger a workflow: product analytics from Amplitude, enriched rows from Clay, internal Slack channels as a destination. Together they push Knock from a notification API toward the messaging control plane, with the agent as the layer that explains what the plane did.
Expect the roles work to continue into audit logs or scoped API keys, since granular permissions without an activity trail is an incomplete enterprise story. More data sources are likely on the same cadence, with the CRM and warehouse categories the obvious remaining gaps.
