What is Jan?

Jan is quietly wiring subagents into the same tool pipeline its main agent uses.

Jan's tagged releases in this window are small: a persisted chain-of-thought duration, a CSP fix that unblocks video uploads, and a change to llama.cpp defaults that turns auto-fit off and pins context length to 8192. Cadence is slow — four tags spanning May to July. The most recent tag is not a release at all but a development checkpoint.

What is opencode?

opencode keeps publishing process-daemon patches on protocol 8.

The newest tags are npm publishes of the process daemon: @opencode/pty reached 0.5.0 on protocol 8 on November 5 and got 0.5.1 and 0.5.2 patches on November 11. Before that came 0.3.x and 0.4.0 on protocol 7, a CI pin and an app animation change. None of these tags describe a change to the agent itself.

Jan vs opencode: editorial side-by-side

AI-ASSISTANTS
5.0

Jan is quietly wiring subagents into the same tool pipeline its main agent uses.

◆ Current state

Jan's tagged releases in this window are small: a persisted chain-of-thought duration, a CSP fix that unblocks video uploads, and a change to llama.cpp defaults that turns auto-fit off and pins context length to 8192. Cadence is slow — four tags spanning May to July. The most recent tag is not a release at all but a development checkpoint.

◆ Where it's heading

That checkpoint is the informative one: subagents now reuse the main native tool pipeline rather than a separate path, alongside code-UI work. Jan is consolidating on one tool-calling surface for both the primary agent and its subagents, which is the precondition for multi-agent workflows inside a local desktop app. The shipped releases meanwhile read as stabilization of the chat surface — durable metadata, predictable inference defaults.

◆ Prediction

The subagent and code-UI work visible in the checkpoint tags should surface in the next minor release; on this cadence, expect more 0.8 stabilization patches before it does.

5.0

opencode keeps publishing process-daemon patches on protocol 8.

◆ Current state

The newest tags are npm publishes of the process daemon: @opencode/pty reached 0.5.0 on protocol 8 on November 5 and got 0.5.1 and 0.5.2 patches on November 11. Before that came 0.3.x and 0.4.0 on protocol 7, a CI pin and an app animation change. None of these tags describe a change to the agent itself.

◆ Where it's heading

The feed shows V2 infrastructure settling into separately versioned components. The protocol bump suggests the terminal layer the agent uses is still changing under the hood.

◆ Prediction

The entries don't show the next user-facing release; a CLI or extension update that adopts protocol 8 is the likely next visible tag.
