OpenClaw Computer Use: 4.27 Release Breakdown

OpenClaw computer use is the headline feature of the new 4.27 release — and it changes what an AI agent can actually do on your computer.

OpenClaw 4.27 dropped this week.

The headline: Codex Computer Use is now built in.

Your AI agent can click buttons, open apps, navigate dashboards.

Plus a lot of reliability fixes.

This post breaks down everything in the release that actually matters.

The Big One: Codex Computer Use

OpenClaw 4.27 ships Codex Computer Use as a first-class feature.

What that means:

• Your agent can control your desktop.
• It can click buttons, open apps, navigate screens.
• It can fill out forms in apps that have no API.
• It can move data between tools that don't talk to each other.

Setup commands:

• /codex-computer-use status — check if ready.
• /codex-computer-use install — install with safety checks.

The install discovers the right MCP server, scans the marketplace, and uses fail-closed safety checks (it stops if something looks off).

This is the kind of feature that turns "AI agent" into "real automation".

Deep Infra As A New Provider

OpenClaw 4.27 adds Deep Infra as a built-in provider.

Why this matters:

• Cheaper access to dozens of models (Llama, Mistral, Qwen).
• One API key covers chat, image generation, image editing, audio transcription, text-to-speech, text-to-video, embeddings.
• Onboarding is automatic — enter the key and OpenClaw discovers the available models.

If you've been burning cash on cloud providers, Deep Infra is worth a look.

Pairs nicely with the DeepSeek + OpenClaw pattern for cheap, fast inference.

File Attachments Actually Work

This was a long-running bug.

Before 4.27, non-image files (PDFs, docs, spreadsheets) would silently get dropped if you sent them through web chat.

Now they come through properly.

If you've been trying to send contracts, reports, or data files to your agent for analysis — this was the blocker.

Fixed.

Strict Model Selection

This is a fix that solves a real reliability problem.

Before 4.27, if your main model failed (API down, rate limit), OpenClaw would silently switch to a different model.

Your agent kept replying — but with whatever backup it could find.

You'd get worse results and not even know.

In 4.27:

• Model selection is strict.
• If your chosen model fails, it fails visibly.
• Optional fallback list — but you have to opt in explicitly.

Same fix applies to scheduled tasks (cron jobs).

If your scheduled model is unavailable, the job tells you instead of running on something random.

Telegram Stability Fixes

If you've been running Telegram-connected agents through OpenClaw, three big fixes:

1. Bad token errors are clear.

Before: invalid tokens gave a confusing "delete web hook failing" error.

Now: clear "your token is wrong" message.

2. Slow sends don't freeze the gateway.

Before: a slow Telegram send could wedge the entire OpenClaw gateway.

Now: bounded by timeouts.

3. Generated images preserved.

Before: agent-generated images would silently disappear from Telegram replies.

Now: images come through properly.

If you're considering a Telegram AI agent, pair it with OpenClaw 4.27 for the best stability.

Slack Improvements

1. Web socket connection now uses ping-pong timeouts (15s default).

Before, the connection went stale silently.

2. File download timeouts prevent Slack file shares from freezing inbound message handling.

3. Reset phrase no longer leaks.

If you typed "new session" to reset, that phrase used to start the new conversation as the first message.

Fixed.

Discord Threading Fixes

Two key Discord changes:

1. Replies private by default.

Group/channel replies are now private unless your agent explicitly uses the message tool.

Before, agents would auto-reply to every message in the channel — noisy and unwanted.

You can opt back into the old behaviour if you want.

2. Long interaction handling.

If your agent took a while (running a tool or doing compaction), Discord's interaction timeout would fire and you'd see an error.

Now handled asynchronously.

Mattermost Double-Message Fix

Regular users were being processed twice — once as a normal message, once as a system event.

Your agent would see the same message twice and sometimes respond to both.

Fixed.

Gateway Startup Improvements

OpenClaw used to wait for your primary AI model to warm up before starting your chat channels.

If your model provider was slow (e.g. OpenRouter having a bad day), Telegram, Slack, and Discord agents would sit there not working.

In 4.27:

• Channels start immediately.
• Model warm-up happens in the background.
• Agents come online faster.

Outbound Proxy Routing

For enterprise setups, OpenClaw 4.27 adds operator-managed outbound proxy routing.

Configure with:

• proxy.enabled
• proxy.proxy_url

All outbound traffic goes through the proxy.

Validates the proxy URL, bypasses loopback, cleans up properly on exit.

If you work somewhere with strict compliance requirements, this was a missing piece.

Sessions And Memory

Two reliability fixes worth noting.

Sessions:

• Heartbeat checks no longer keep stale sessions alive.
• Clock skew can't keep stale sessions.
• Oversized session files no longer trigger auto-rotation backups on every write.
• New doctor command to clean things up if needed.

Memory dreaming:

• Cap on dreaming background processes (no more chain reactions eating resources).
• Retries with default model if dreaming model unavailable.

Should You Update?

Honest advice from the release notes:

If your current setup works, you don't have to update.

Updates can break things.

Always create a backup before updating.

If you specifically want computer use, Deep Infra, or any of the channel fixes — update.

If not, stay where you are.

My Take After Testing

I updated immediately for computer use.

It's already saving me time on:

• Filling forms in legacy admin tools.
• Moving data between tools that don't have APIs.
• Triggering workflows in apps without integrations.

Computer use is the feature that turns OpenClaw from "chat with files" into "real automation engine".

Worth the update for that alone.
