**Inspecting model resolver**

I think I need to take a closer look at the lines in model-resolver.js. It’s likely important to understand how it’s functioning or potentially troubleshoot it if something’s not working as expected. Each line could have a significant role, so I want to make sure I’m being thorough. Once I check it out, I’ll have a better sense of how to proceed. Let's dig into that!

bash

set -e
TMP=$(mktemp -d)
cd "$TMP"
URL=$(curl -s https://registry.npmjs.org/@mariozechner/pi-coding-agent/latest | jq -r '.dist.tarball')
curl -L -s "$URL" -o pkg.tgz
tar -xzf pkg.tgz
sed -n '1,120p' package/dist/core/model-resolver.js

**Clarifying npm version support**

I need to provide a concise answer that clearly says yes and backs it up with evidence. I want to mention that the latest upstream version is npm 0.73.1, but I have 0.74.0 installed locally. There isn’t a README in the online repo/docs, but the package source does have a built-in provider. I could also mention that it’s officially supported in the code, although that’s not prominently documented.

Yes.

Upstream check says **DeepSeek is built-in / officially supported**.

Proof:
- `pi --help` lists:
  - `DEEPSEEK_API_KEY`
  - `--provider deepseek`
- Upstream package source has built-in provider name:
  - `deepseek: "DeepSeek"`
- Upstream default model map includes:
  - `deepseek -> deepseek-v4-pro`

Online upstream package:
- npm latest seen: `@mariozechner/pi-coding-agent 0.73.1`
- local install here: `pi 0.74.0`

One nuance:
- It looks **supported in code/CLI**.
- It is **not prominently documented** in README/sdk docs from what I checked.

If you want, next I can tell you the exact command to use it on this Pi.
