Introducing Agent Mode: Agentic AI is now measured in the Arena.
Agent Mode can do deep research, create reports, generate images, build websites, debug code, and more.
It completes more complex tasks by using tools like web search, bash in a sandbox environment, image
Thrilled to see Seedream 5.0 Pro debut at #2 on @arena ’s Multi-Image Edit leaderboard.
It’s especially encouraging to see the leap from #11 with Seedream 4.5 to #2 with Seedream 5.0 Pro. Independent community evaluations like Arena help push everyone to build better models.
Exciting news: @OpenAI’s GPT-5.6-sol is now joint #1 in the Code Arena: Frontend, matching Claude Fable 5!
This marks the first time an OpenAI model has reached the top spot in Code Arena, demonstrating major gains in agentic coding, frontend and web app development.
If you've been relying on skills or special prompt tricks to make frontends with 5.5, I recommend trying 5.6-sol without them. The default behavior should be quite good.

Muse Spark 1.1 ranks #9 on Code Arena: Frontend.
Highlights:
- #2 in the Data & Analytics domain
- Top 10 in domains like Reference-Based Design, Simulations and Content Creation Tools
Muse Spark 1.1 has entered the Code Arena: Frontend at #9!
Muse Spark 1.1 reshapes the cost-performance Pareto Frontier by scoring 1541 at a blended $3.5M ($1.25 per input MToken, $4.25 per output MToken). This is frontier performance at a fraction of the price.
Congrats to
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
Across the 15 selected categories in the Text Arena, Muse Spark 1.1 improves in 12.
The largest increases are:
- Expert: #36 -> #15
- Instruction Following: #26 -> #5
- Longer Query: #34 -> #15
- Life, Physical & Social Science: #14 -> #6
