What is Ably?
Ably is rebuilding its realtime stack around AI agents: transport SDK and agent-native CLI
Ably is repositioning its realtime messaging infrastructure around AI agents. The clearest evidence is a dedicated AI Transport SDK, now with a session/run model, conversation branching, and human-in-the-loop handoff, plus a CLI rebuilt to be agent-operable that installs Agent Skills into Claude, Cursor, and Windsurf and emits structured JSON for self-healing automation. Underneath, the core Pub/Sub and Chat SDKs keep maturing and platform reach widens with a new Dart/Flutter SDK.
What is Cohere?
Cohere is widening from chat into a full enterprise model suite: code, audio, and retrieval.
Cohere is shipping across its whole model lineup: a new Command A+ flagship in May, the North-Mini-Code coding model in June, the Transcribe ASR model earlier in the spring, and Rerank/Embed v4 for retrieval. Alongside the launches, it has been aggressively retiring older Command, Embed, and Aya models plus legacy RAG endpoints. The portfolio is consolidating around the Command A family, embed-v4/rerank-v4, and now code and audio.

Ably is rebuilding its realtime stack around AI agents: transport SDK and agent-native CLI
◆ Current state
Ably is repositioning its realtime messaging infrastructure around AI agents. The clearest evidence is a dedicated AI Transport SDK, now with a session/run model, conversation branching, and human-in-the-loop handoff, plus a CLI rebuilt to be agent-operable that installs Agent Skills into Claude, Cursor, and Windsurf and emits structured JSON for self-healing automation. Underneath, the core Pub/Sub and Chat SDKs keep maturing and platform reach widens with a new Dart/Flutter SDK.
◆ Where it's heading
The trajectory is realtime-as-agent-infrastructure: the AI Transport SDK is iterating fast toward production agent apps with branching, suspend/resume, and tool-calling, while the tooling is built so AI coding agents, not just humans, can drive Ably. The conventional SDK and CLI work continues in parallel, but the directional energy is clearly aimed at the agent stack.
◆ Prediction
Expect the AI Transport SDK to keep adding agent-conversation primitives on its march to 1.0, and the Dart SDK to fill toward parity with the JS line.
Cohere
7.5INFRA · APIS
Cohere is widening from chat into a full enterprise model suite: code, audio, and retrieval.
◆ Current state
Cohere is shipping across its whole model lineup: a new Command A+ flagship in May, the North-Mini-Code coding model in June, the Transcribe ASR model earlier in the spring, and Rerank/Embed v4 for retrieval. Alongside the launches, it has been aggressively retiring older Command, Embed, and Aya models plus legacy RAG endpoints. The portfolio is consolidating around the Command A family, embed-v4/rerank-v4, and now code and audio.
◆ Where it's heading
Cohere is broadening from a chat-and-retrieval vendor into a multi-modal enterprise model suite, adding speech-to-text and now a code-specialized model, while pruning everything that predates the Command A generation. The steady deprecation cadence signals a deliberate narrowing to a smaller, current set of supported models rather than a sprawling catalog.
◆ Prediction
Expect a fast or larger sibling of North-Mini-Code, mirroring the pro/fast split Cohere already ships for Rerank, and continued retirement of pre-Command-A models as customers are steered onto the current generation.
