July 9, 2026 v0.28.0 → v0.30.0 plus panel 0.6.9 → 0.7.3. The local-LLM story from the day before rounds out to every major local runtime, the first mobile building blocks land, and the gemma4 fine-tune ladder gets honest Arena numbers.

​
More local backends: LM Studio, llama.cpp, custom endpoints

  • LM Studio as a first-class local backend (#160), with a full hands-off model/server lifecycle (#164) — the agent can load the model and start the server itself.
  • llama.cpp (llama-server) as a first-class local backend (#161).
  • Custom OpenAI-compatible endpoint as a first-class backend (#162) — point the panel at anything that speaks the API.
  • Temperature pinned to 0 for these backends — nondeterministic empty finals after tool results are gone (#166).
Each ships with its own panel chip + setup card (panel 0.6.9 / 0.7.0).

​
Mobile building blocks: phone pairing + render mailbox

  • On-demand phone pairing (#180) — a token-gated LAN/tunnel listener; nothing is exposed until you ask.
  • Render mailbox (#182) — never lose a render while the phone is away; headless (mobile/remote) tabs get renders delivered in-turn (#165) and show_media can inline media bytes for clients with no ComfyUI reachability (#171).

​
gemma4 fine-tune Arena results

LLM Arena results for the gemma4-comfyui-mcp ladder: :e4b 14/20 (best local model tested), :12b 13/20, and :e2b honestly flagged at 4/20 pending its v2 training fix. Leaderboard SVGs + model-sizing guidance updated across the docs and the Ollama onboarding copy. Full story on the blog.

​
Workflow intelligence + node development

  • query_workflow (#179) — filter / traverse / aggregate over big workflows without loading the whole graph into context.
  • Graph-health findings in validate_workflow / analyze_workflow (#175) — disconnected nodes, missing required inputs, duplicate model loads, orphaned branches, muted/bypassed nodes.
  • Node-dev tools (#173) — path-jailed read/search/write/patch plus per-pack git for custom_nodes; commit/push stays behind COMFYUI_MCP_ALLOW_GIT_WRITES.
  • get_comfyui_settings / set_comfyui_setting (#174) — read/write ComfyUI’s own user-settings store. calculate (#176) — safe batch math with variables and seeded RNG.
  • panel_auto_layout (#177) — one-shot topological canvas auto-arrange, and panel_connect auto-matches slots by type with full diagnostics on failure (#178).

Panel: survives tab switching

The agent now keeps working when you switch to another sidebar tab (0.7.3) — the panel detaches instead of tearing down, so the connection, session, and chat survive, and an activity badge on the tab icon shows a green spinner while a turn runs and a red dot when it finished while you weren’t looking. Bridge-driven graph mutations became properly undoable (one command = one Ctrl+Z, 0.7.1), and a “Remote control” QR button (behind a default-off beta toggle) previews phone pairing.
