You can try the hosted model before its weights arrive. Record which version and access route produced the result, then compare it with another coding assistant.
What is available now
Moonshot’s October 23 announcement introduces Kimi K3.1 Pro and Highspeed through Kimi’s hosted services. It names Kimi.ai, Kimi Work, Kimi Code, and the API. The same announcement promises full weights by November 4, 2026.
That leaves two different deployment decisions. An eligible account can start a hosted trial. Running the released weights requires the actual files, their license, and hardware requirements when they arrive.
Moonshot reports speed and benchmark improvements. Those measurements do not establish the fastest or best model for a reader’s repository. We have not reproduced them.
Check the Kimi Code plan and thinking settings
The Kimi Code release notes place Pro access at Plus/Moderato and above. The 1M-token context option and Highspeed require Pro/Allegretto or a higher plan. These are Kimi Code subscription rules; do not apply them automatically to the separate API.
K3.1 uses thinking mode, with low, high, and max levels. High is the default. Disabling thinking returns a 400 error, per the release notes.
The notes recommend starting a fresh session. Enterprise access is off by default at launch, so an administrator may need to enable it before a user can select the model.
Use a task that exposes integration problems
I would start with a single, contained repository change with a deterministic acceptance check. Give each comparison run the same starting commit, instructions, and available tools.
- Record the plan, selected model, and access route.
- Save the thinking level and effective context limit.
- Check the proposed changes against the requested behavior.
- Run the repository’s relevant checks and inspect the diff.
- Record elapsed time, retries, and actual usage charges.
A long context window can hold more material, but it doesn’t prove the model used the important file correctly. Include a requirement whose answer depends on a specific repository detail.
Keep the hosted trial separate from a weights evaluation
Save the hosted run as a dated baseline. When the weights are released, repeat the task with the exact downloadable version and inference configuration.
Compare accepted changes and review time alongside latency. Otherwise, a faster generation can hide additional correction work, or a different thinking setting can make two runs look more comparable than they are.
Our Kimi K3 on Bedrock article covers a different hosting route. The Chinese model comparison offers a broader framework for selection.
