Per-model settings were mirrored to the server as two fields only,
llama_extra_args and max_seq_length. Everything else lived in browser
localStorage, so a model loaded by an API request came up with app
defaults for context length, KV cache dtype, speculative decoding,
tensor parallel and GPU placement.
Store the full config server side and map it onto the same LoadRequest
the picker builds, so a remote load and a picker load of the same model
produce the same command line. Entries are keyed per quant, falling back
to the bare repo id so existing entries keep resolving.
Also moves the API monitor out of the settings tab: a full page at
/api-monitor, plus a floating panel that opens itself when traffic
arrives, and a settings page per model reachable from the Hub.
* Studio: trim serving-log noise and surface llama-server engine stats
Studio prints one structured line per HTTP request, so the SPA's polling and
per-invalidation fan-out bury the lines that matter.
- Dedup identical successful GETs within a short window (default 300ms,
UNSLOTH_STUDIO_ACCESS_LOG_DEDUP_MS) so a burst logs once. The dedup key
includes the query string, so distinct query-driven GETs are not collapsed.
Runs after the response is sent, so it adds no request latency; mutations,
non-2xx, and loading polls are untouched.
- Collapse pure-liveness polls (/api/health, /api/auth/status,
/api/inference/status, /api/inference/monitor) to a longer heartbeat
(default 10s, UNSLOTH_STUDIO_ACCESS_LOG_POLL_DEDUP_MS). The API monitor
console polls /monitor every 1.5s while open.
- Translate llama-server's Prometheus /metrics into a periodic vLLM-style
engine_stats line (generation/prompt throughput and requests in flight) from
a daemon poller, gated on UNSLOTH_STUDIO_ENGINE_STATS. Throughput uses
llama-server's predicted_tokens_seconds / prompt_tokens_seconds gauges, with
a tokens_predicted_total / prompt_tokens_total counter-delta fallback; it does
not use n_decode_total (which counts llama_decode() calls, not tokens). No KV
field is emitted, since llama.cpp does not expose kv_cache_usage_ratio.
--metrics is added only when probe_server_capabilities reports the binary
supports it, so older/custom binaries still load. The poller keeps retrying
through transient scrape failures (stop() drives shutdown) and a malformed
sample cannot crash its thread.
- api_monitor.append_reply: once the preview cap is reached, skip the per-chunk
re-concat (avoids O(n^2) on long generations) while still recording the "..."
truncation marker for a reply that lands exactly on the cap.
- unsloth studio --verbose and unsloth studio run --verbose both restore every
per-request log; --verbose before a subcommand is rejected with guidance
(matching --secure / --parallel). run --verbose still forwards --log-verbose
to llama-server, preserving the pre-existing pass-through verbosity.

Backend:
- Finalize the monitor entry as error on the chat-completions validation
reject paths (addresses the codex P2 comment around line 2337). Adds a
small _reject helper next to the api_monitor.start so each early-raise
in the GGUF tool-passthrough, non-empty-messages, GGUF vision/audio,
PIL image decode, and text-only model branches no longer leaves the
entry stuck running until eviction.
- _monitor_openai_chunk is now defensive about malformed shapes
(non-list choices, non-dict choice/delta) so a misbehaving provider
chunk does not raise into the streaming generator and abort the
user's response.
- _monitor_openai_sse_line accepts both data:value and data: value per
SSE spec; previously the single-space-only prefix silently dropped
tokens from compact emitters.
- openai_completions stream now keeps a residual buffer between
aiter_bytes chunks so a data: line whose newline lands in the next
TCP frame is reconstructed before parsing, instead of being dropped
by the per-chunk splitlines call.
api_monitor:
- duration_ms is derived from time.monotonic anchors and clamped at 0,
so NTP / manual clock steps no longer produce negative durations.
- finish() and fail() are idempotent: a second call (for example [DONE]
arriving after the generator's finally block already ran) no longer
moves finished_at or finished_monotonic.
- set_usage only derives total_tokens when no authoritative total has
been recorded, so a later partial-usage chunk does not clobber a
provider-reported total from an earlier chunk.
- _trim guards limit < 3 so the slice cannot underflow.
Tests:
- Adds regression coverage for the new idempotency, total preservation,
monotonic clock, and _trim guard behaviour.
