Emdash (YC W26)

Open-source Agentic Development Environment

[Emdash (YC W26) @emdashcom]

@rashed_sahaji @elmd_ @zeddotdev @rashed_sahaji we also have a chat ui via acp :)

What are we building with K3 today?

[Emdash (YC W26) @emdashcom]

Use Grok 4.5 in Emdash

➡️Grok 4.5 is built for real-world engineering: navigating large codebases, working across multiple repositories, and completing long-running tasks with a variety of tools.

➡️It combines fast, token-efficient reasoning with strong coding performance. It’s served at 80 tokens per second and priced at $6 per million output tokens.

➡️Grok 4.5 ranks #2 on @ProximalHQ’s FrontierSWE leaderboard: behind only Claude Fable 5 and ahead of Opus 4.8, GLM-5.2, and GPT-5.5.

[Proximal @ProximalHQ]

Grok 4.5 ranks #2 on FrontierSWE

It is only outperformed by Claude Fable 5 and ranks higher than Opus 4.8, GPT-5.5 and GLM-5.2

[Emdash (YC W26) @emdashcom]

Use GLM-5.2 (@Zai_org) in Emdash

➡️ GLM-5.2 is built for long-horizon coding work: understanding large codebases, following repo conventions, and completing multi-step engineering tasks.

➡️ It’s open weight, MIT licensed, supports a 1M-token context window, and offers strong price-performance compared to closed frontier models.

Introducing GLM-5.2: Frontier Intelligence, Open Weights

- Significant improvements in coding and agentic tasks
- Strong long-horizon capabilities with a 1M context window
- Two levels of reasoning effort: GLM-5.2 (max) pushes the limits, while GLM-5.2 (high) strikes a strong balance between performance and token efficiency
- MIT-licensed open weights
- Same API pricing as GLM-5.1

We've got something for you

[Arne Strickmann @arnestrickmann]

What a model week

[Emdash (YC W26) @emdashcom]

Muse Spark 1.1 is now available in Emdash with OpenCode.

[AI at Meta @AIatMeta]

We’re excited to introduce Muse Spark 1.1, a significant upgrade from the first Muse Spark model we released earlier this year.

Along with this release, we are launching a public preview of the new Meta Model API where developers can access Muse Spark 1.1.

The model is also available now in "Thinking" mode in the Meta AI app and on https://t.co/wHkMPH82ZH.

GPT-5.6 Sol is now live in Emdash.

Compare it against Fable, GLM-5.2, Kimi-K2.7, or any other model.

[Arne Strickmann @arnestrickmann]

Grok 4.5 is now in Emdash.

Try it and compare it with Fable, Opus 4.8, GPT-5.5, GLM-5.2, or Kimi-K2.7 on real coding tasks.

[Emdash (YC W26) @emdashcom]

What are we building today?

[Arne Strickmann @arnestrickmann]

Finally using Kimi K2.7 Code in Emdash.

Strong coding intelligence, 256k context, and concise reasoning make it especially interesting for long-running coding tasks.

Curious to see how it holds up against /goal runs with Grok and Codex.

[Arne Strickmann @arnestrickmann]

Set your default agent and model for scheduled automation runs in the Emdash control center 🎛️

Coming to Emdash very soon.

[raban @rabanspiegel]

Emdash crossed 1m github release asset downloads.

Grateful. Just getting started!

[Emdash (YC W26) @emdashcom]

Qoder CLI support is coming to Emdash.

Try it in the next release!

[Qoder @qoder_ai_ide]

Stop prompting one agent. Start orchestrating a team.

Qoder CLI Workflows are here — multi-agent execution that decomposes, parallelizes, and recovers.

[Emdash (YC W26) @emdashcom]

Emdash just crossed 5,000 stars on GitHub.

Excited about our recent progress and what’s to come!

[raban @rabanspiegel]

ChatUI coming to Emdash. Escaping the terminal!

[Emdash (YC W26) @emdashcom]

New prod release! Emdash v1.1.35 is out.

SSH port forwarding for remote previews, plus browser profiles, a global auto-approve default, and faster task and tab navigation.

And smaller updates for agent integrations, automation controls, and reliability. And many, many fixes!

[Arne Strickmann @arnestrickmann]

Super excited about this addition as more and more software development moves onto remote machines:

SSH port forwarding is now live in Emdash!

When a dev server starts on a remote machine, Emdash detects it, forwards the port locally, and gives you a clickable preview URL so you can review the app right inside the Emdash browser.
