+## Evening Session (2026-08-17): tool calling, model swap, batch 8192
+
+Three changes landed after the initial deployment:
+
+### 1. Tool calling on frank-default-small (HTTP 400 fix)
+
+Clients (pi) send `tool_choice: "auto"`. vLLM rejects it with HTTP 400
+unless the server enables tool calling. Fixes applied:
+
+- `--enable-auto-tool-choice --tool-call-parser qwen3_xml` (the Avesed /
+  Quark chat template renders the Qwen3 XML tool format, and qwen3_xml
+  is the matching parser).
+- Custom chat template `/home/dank/models/qwen36-chat_template-tools.jinja`:
+  derived from the repo's `chat_template.jinja` (the tokenizer_config.json
+  ships no template, so vLLM would use its built-in one, which does not
+  render the XML tool instructions). The custom template adds:
+  - a concrete WORKED EXAMPLE built from the actual tool schema
+    (name + parameter keys) — models follow concrete examples much
+    better than the generic placeholder;
+  - tool requests default to non-thinking (`enable_thinking` unset + tools
+    present -> empty think block). Qwen3 tool calls only work reliably
+    with thinking off; normal requests keep thinking.
+
+Known pitfall: the earlier Avesed model still emitted malformed XML even
+with the strong template (`<function=get_weather(city=...)>`); that was
+model behavior, which motivated the swap.
+
+### 2. Model swap: Avesed INT8 W8A8 -> Quark W8A8 INT8
+
+`frank-default-small` now serves
+`nameistoken/Qwen3.6-35B-A3B-Quark-W8A8-INT8` (AMD Quark 0.11.1, ~35 GB,
+vLLM-native expert layout). The Avesed compressed-tensors quant's
+Qwen3-XML tool fidelity was poor. Verified with the Quark model: plain
+tool requests (no chat_template_kwargs) return clean
+`tool_calls: [{"name": "get_weather", "arguments": {"city": "Paris"}}]`;
+non-tool requests keep reasoning. The Avesed checkpoint stays in the HF
+cache for rollback.
+
+### 3. Batch 8192
+
+`MAX_NUM_BATCHED_TOKENS` lowered from 16384 to 8192 (user request).
+vLLM has no separate ubatch knob; the scheduler issues one batch per
+step up to this token cap.
