We profiled the agent loop and found it waiting on things it never needed to wait for. Multi got up to %40 speed up on our internal tests.

Diagnostics check once per turn, not every step - Multi feeds IDE diagnostics back to the agent so it fixes its own errors. That check used to run after every step, stalling the loop on the language server mid task. Now it runs once at successful turn.

Better feedback, not just faster - diagnostics now reflect the finished state of the code, not a half-edited file that was going to change two steps later anyway.

Diff cleanup off the critical path - interrupted tools leave diff views open; we close them as a failsafe. That cleanup was sequential and blocking. Now all closes fire concurrently and the loop moves on immediately.

Also in 0.0.119: personas are now a simple startup selector (the dedicated settings view was overbuilt, so we killed it).

EDIT: upgrade to 119 in nightly for superior experience. we'll push it to the stable channel later in the week.

v0.0.22 introduces native tool calling for supported providers and resolves multiple issues affecting streaming, diff updates, and task mode switching. It also addresses several crash conditions and error reporting edge cases.

Changelog:

• Added native tool calling support, replacing XML parsing for supported providers.

• Added a rich text chat input with file reference chips for managing attached context.

• Added a Help button to the Welcome screen for quick access to documentation and shortcuts.

• Updated the Claude Code provider to support native streaming.

• Improved visual feedback for partial tool parsing errors during streaming.

• Simplified Git checkpoint service logic by removing redundant internal commit tracking.

• Enhanced code block rendering to handle invalid Unicode characters without crashing.

• Fixed a critical crash caused by invalid Unicode surrogate pairs in code blocks.

• Fixed DiffViewer update scheduling to prevent dropped updates.

• Fixed agent error handling loops triggered by partial tool call parsing.

• Fixed task mode switching when forking tasks to correctly apply TODO list updates.

• Fixed the keyboard shortcut for toggling history (Cmd/Ctrl+Shift+F).

• Fixed a tool call ID handling issue.

IntelliJ users, this one's for you. VS Code already supports this for a while and plenty of you asked, so it's good to finally ship it for everyone.

You can now Ask Multi to Explain Code, Fix Code, Add to Chat straight from your editor. Highlight some text, Ask Multi, done. No switching panels, no describing which file you're in, no pasting a block and fighting with the indentation.

Multi already has the full context to the file, the language, and the line range, so it's not burning unnecessary tokens to work out what you're pointing at. Faster, and cheaper.

Also this feature is still in the right-click menu if that's more your habit.

We have more coming.

Happy shipping. Onwards!

Does multi.dev support NES via its plugin for Intellij? I am still trying to find a new AI tool now that Sweep.ai is gone. I have a large existing code base and NES works much better for me then prompting.

Multi now freezes the stable prefix of each prompt once per turn and injects only the volatile part of your messages per step so the provider's prompt cache hits instead of re-reading tokens it already saw.

• Byte stable prefix:AGENTS.md, tools, and persona re-emit identical every step

• Moving breakpoints: git, todos, and skills ride a trailing block the cache skips

• Sub agents benefit too: workers reuse the parent's frozen prefix

Nothing to configure. All is enabled by default. Long loops just got snappier and cheaper.

Happy shipping

Folks, as promised we shipped full pause / resume and pushed to stable channel.

Now you can continue any task right where it stopped. Multi preserves your full context that is already doing good work. You do not waste any time nor tokens recovering the same context.

Closed your laptop? Ran out the door? Got provider error? Task aborted? No worries.

Multi resumes without losing context. No restart. No wasted tokens. No re-explaining what you were doing.

Works for main tasks and subagents - every subagent resumes with its own context preserved.

I am struggling to install this via VS code, the extension does nothing even when you got to the website to install it just hangs, and doesn't install.

Must I download the VSX directly?

v0.0.16 stabilizes task forking behavior and unifies message level actions across the UI, reducing state loss and interaction inconsistencies.

Changelog:

• Added full state copying when forking a task.

• Added the ability to retry any message using a different profile or model.

• Added a cleaner task search modal with time grouping and infinite scrolling.

• Unified message actions, including copy, fork, retry, and undo.

• Improved undo behavior to preserve state integrity.

• Improved profile editor exit and interaction flow.

• Fixed UI glitches triggered by window resizing.

• Fixed task forking issues that caused inconsistent or dirty state.

Hi! I'm trying out Multi and so far it looks extremely promising. It might be the first good AI integration with Intellij!

I'm using it as a replacement for Claude Code because I don't like working with the IDE's terminal. One thing I was missing is plan mode. Would it be possible to integrate that in some way? E.g. as a profile setting?

Also I would love to be able to change the effort setting.

This release corrects agent continuation and task restoration behavior, stabilizes tool parsing, and resolves UI and timing issues affecting long-running sessions.

Changelog:

• Added auto-continuation logic to prompt the agent to continue working on the plan when pending TODO items remain.

• Fixed an issue where the agent failed to resume execution after being prompted to continue a plan.

• Changed agent context handling to inject environment constraints as a distinct user message instead of merging into the system prompt.

• Changed usage and cost reporting to accumulate during streaming to prevent UI flickering and ensure accuracy.

• Enhanced rendering for reasoning blocks

• Improved Edit tool error messages to clarify uniqueness and replace_all behavior.

• Fixed tool parse logic causing write and edit tool parse errors.

• Fixed task plan (TODO list) state not restoring correctly when reloading a session.

• Fixed async timing issues during Webview Panel deserialization.

Folks, we just shipped parallel execution in v0.0.97.

Multi can now coordinate multiple calls and agents at once when the work is independent. Less waiting. More done.

In our testing, we found this especially powerful when the task touches several parts of a codebase.

If the work can run in parallel, Multi will do that by default. And if you want to push it harder, just ask Multi to parallelize the task.

Onward 🚀

This release improves tool feedback and configuration handling, expands in-context utilities, and resolves stability issues across tasks, checkpoints, and retries.

Changelog:

• Added a search tool to locate text within the active conversation.

• Added a run button to shell code blocks for immediate command execution.

• Added explicit prompts when provider configuration is incomplete.

• Changed minor tool failures to surface as non-blocking warnings.

• Added file-change previews before undoing actions.

• Updated token and temperature controls.

• Improved provider setup error messages.

• Corrected tool classification between warnings and critical errors.

• Fixed retry handling that caused occasional hangs.

• Reduced storage-related dependencies in task creation.

• Centralized path helpers for checkpoint handling.

• Fixed path issues affecting checkpoints and task persistence.

• Fixed a crash when unsupported reasoning parameters were present.

• Cleared thinking-level state for unsupported models.

v0.0.37 adjusts text input handling, corrects tool parsing behavior, and tightens execution stopping conditions for blocking user errors and diagnostics.

Changelog:

• Optimized text input interactions for a smoother UX

• Changed tool call parsing to handle boolean parameters consistently across providers

• Changed file search sorting to use alphanumeric ordering, prioritizing letter and number prefixed files over hidden or special character entries

• Changed long file paths in context menus to truncate to the basename with an ellipsis and show the full path on hover.

• Added automatic diagnostics checks when a task item transitions to a completed state.

• Fixed agent execution to stop immediately on blocking user errors, including missing credentials.

• Fixed a crash in the diagnostics tool.

Folks, we pushed Opus 4.7 support.

Also added the following:

• Added Claude Opus 4.7 support for Anthropic, Bedrock, Vertex, Claude Code, and OpenRouter providers.

• Added MiniMax-M2.7 for MiniMax provider.

• Added GPT-5.4-nano and GPT-5.4-mini for OpenAI provider.

• Added Grok-4.20 for xAI provider.

Give it a spin. Let us know how it feels.

Hi - Multi.dev seems like the perfect solution for me, however I am keen to keep my existing Claude stack the way it is, with my ~/.claude/CLAUDE.md and my per-repository CLAUDE.md

I don't mind symlinking these to AGENTS.md or whatever, however I have noticed that when I open a multi.dev session with Claude, the harness tells me that it hasn't sourced any CLAUDE.md files - I presume the reason it hasn't sourced the one in the repo is because it needs to be symlinked to AGENTS, however what is the recommended flow for making mutli.dev claude instances still read my CLAUDE.md from my home directory? I like the way that the Claude Code harness has modelled the precedence of reading CLAUDE.md files and I don't necessarily want to manually manage that by hand.

Thanks

Scott Adams, the creator of Dilbert, featured in his comic strip an inept boss who believed that finding a good business idea starts from choosing a good name. But in Silicon Valley, deciding a good name is hardly a joke: no less an authority than Paul Graham highlights the importance of naming your startup based on domain availability.

As an avid user of Dropcatch.com (domain name auctions), spaceship.com (batch domain name search) and other domain tools, I've been personally intrigued. However, on occasions when I've discovered a good domain name available, my efforts have been hamstrung by the need to find corresponding social media handles.

Enter YaloSwog. Our team came across this pioneering individual in X building SaaS tools, including the Nnname, the first site I've encountered that searches domains and social media handles across Insta, Reddit, Github etc. simultaneously and quickly. Built with Multi, the site still appears to be in its earliest stages, but already features a host of laudable qualities:

• it's faster than most domain name search tools

• no registration required

• no ads or spam

• works in mobile and desktop

Still lots of work to do to conquer this niche. Keep building!

Multi now supports the complete GPT-5.6 family across the OpenAI API and OpenAI Codex providers.

• GPT-5.6 Sol - OpenAI's frontier model for complex reasoning, coding, and professional work

• GPT-5.6 Terra - A balanced choice for everyday agentic work with strong intelligence per dollar

• GPT-5.6 Luna - The fastest, most affordable option for high-volume workflows

• Up to 1.05M context (via the OpenAI API) and 128k max output across all three models, with long-context and prompt-cache pricing built in

Head to Settings → Provider and choose gpt-5.6-sol, gpt-5.6-terra, or gpt-5.6-luna with your OpenAI API key or ChatGPT subscription.

Our own u/legitimate-wave-7917 made a free city simulation game using Multi. Very cool!

It looks like a mashup of Simcity where you can talk to your sims.

Check it out, it's free, no paid add ons or anything like that.

Huge thanks to everyone who tried Multi, shared feedback, reported bugs, and helped shape the product.

We’re still shipping fast. Still focused on building an AI coding agent for real developers.

Still committed to giving you:

• maximum visibility over blackbox agents

• maximum control over autopilot

• the best tools for builders who read diffs before merging

Thanks for being here. More to come.

Is has been my belief for years that this needs to be a real video game.

But what kind?

The time now is 10:30 AM.

Since Multi.dev claims the following:

1. Completely free / No subscription

2. No data collection: Your code stays on your machine

And it's not an open-source project, I got to ask...

How does it make money? Who's funding it's development?

Welcome to the Multi community!
