Ollama publishes embeddinggemma:300m with general.architecture=gemma3
plus two extra dense projection layers stored as `dense.0.weight` /
`dense.1.weight` (the sentence-transformers post-pooling head, mapping
the 768-dim pooled embedding through 768→3072→768).
Upstream loads this model under arch=gemma-embedding, which both
disables causal attention (embeddings are bidirectional) and loads
`dense_2`/`dense_3` by name from the gemma-embedding.dense_*_feat_*
hparams. Without that arch, the gemma3 loader leaves dense.0/dense.1
unrequested and `done_getting_tensors` raises "wrong number of
tensors; expected 316, got 314".
Detection: arch=gemma3 AND has dense.0.weight tensor (only
embeddinggemma ships these — regular gemma3 chat models do not, so
the existing handle_gemma3 path remains for them).
Translation:
* switch arch_name to gemma-embedding (used by the loader to build
KV lookup prefix for subsequent reads)
* copy gemma3.* KV prefix to gemma-embedding.*
* derive gemma-embedding.dense_{2,3}_feat_{in,out} from the actual
dense tensor shapes
* rename dense.0/dense.1 → dense_2/dense_3
Verified via /api/embed: returns 768-dim vectors with correct cosine
similarity ordering (similar sentences cluster, dissimilar ones don't).
Confirmed gemma3:1b chat path is unaffected — handle_embeddinggemma's
detection only matches blobs with the dense.0 tensor present.

Libraries
Community
Get started
ollama
You'll be prompted to run a model or connect Ollama to your existing agents or applications such as Claude Code, OpenClaw, OpenCode , Codex, Copilot, and more.
Coding
To launch a specific integration:
ollama launch claude
Supported integrations include Claude Code, Codex, Copilot CLI, Droid, and OpenCode.
AI assistant
Use OpenClaw to turn Ollama into a personal AI assistant across WhatsApp, Telegram, Slack, Discord, and more:
ollama launch openclaw
Chat with a model
Run and chat with Gemma 3:
ollama run gemma3
See ollama.com/library for the full list.
See the quickstart guide for more details.
REST API
Ollama has a REST API for running and managing models.
curl http://localhost:11434/api/chat -d '{
"model": "gemma3",
"messages": [{
"role": "user",
"content": "Why is the sky blue?"
}],
"stream": false
}'
See the API documentation for all endpoints.
Python
pip install ollama
from ollama import chat
response = chat(model='gemma3', messages=[
{
'role': 'user',
'content': 'Why is the sky blue?',
},
])
print(response.message.content)
JavaScript
npm i ollama
import ollama from "ollama";
const response = await ollama.chat({
model: "gemma3",
messages: [{ role: "user", content: "Why is the sky blue?" }],
});
console.log(response.message.content);
