Actual Computer Setup Skill
Sets up actual.inc (Actual Computer) as a Loki inference
provider. Actual turns the user's own hardware into a private inference cluster
and exposes an OpenAI-compatible API two ways: a hosted end-to-end-encrypted
relay at https://api.actual.inc (authenticated with an ac_ key), and a local
on-device daemon at http://127.0.0.1:8080 (no auth on loopback). This skill
does not install the Actual daemon for the user — device authorization requires
a human in a browser.
When to Use
- User wants to add actual.inc as an inference provider (cloud relay or local).
- User has an
ac_ key and wants Loki routed through their Actual cluster.
- User wants fully-local, on-device inference via the Actual daemon.
- Troubleshooting: Actual requests failing with cryptic 400s or empty streams.
Prerequisites
- Loki has first-class
actual provider support (provider id actual,
aliases actual-computer, actualcomputer, aci). Do NOT configure Actual
as a custom_providers / providers.actual.* entry on current Loki — the
built-in provider owns the name and handles base-url normalization, the
Responses transport, and local no-auth automatically.
- Relay mode: an Actual account and an
ac_ inference key from
https://actual.inc/user/keys.
- Local mode: the user has installed the daemon
(
curl -fsSL "https://actual.inc/install" | bash) and completed device
authorization by running actual once and opening the printed
https://actual.inc/device?code=... URL in a browser. Relay that URL to the
user and WAIT — never invent an email or authorize on their behalf. Codes
expire in 5 minutes; re-run actual for a fresh one.
How to Run
Relay / API mode
- Put the key in
.env (secrets only — never config.yaml):
append ACTUAL_API_KEY=ac_... to ~/.loki/.env.
- Verify the key and discover models with
terminal:curl -s https://api.actual.inc/v1/models -H "Authorization: Bearer $ACTUAL_API_KEY"
- Select provider + model:
loki config set model.provider actual
loki config set model.default "MODEL_ID_FROM_DISCOVERY"
- Verify end-to-end:
loki chat -Q -q "Reply with exactly: ACTUAL_OK" --provider actual -m MODEL_ID
Local mode
- Human has installed + authorized the daemon (see Prerequisites).
- Download and load a model (scriptable once authorized):
actual models search "qwen2.5 0.5b instruct gguf" --limit 8 --no-prompt
# Downloads REQUIRE an explicit quantization (409 ambiguous_model_download otherwise):
actual models download "Qwen/Qwen2.5-0.5B-Instruct-GGUF/Q4_K_M"
actual models list # note the INSTALLED name (differs from download id)
actual models load "qwen2.5-0.5b-instruct-q4_k_m" # load by installed name
- Point Loki at the daemon.
ACTUAL_BASE_URL with a loopback host flips the
built-in provider into local no-auth mode automatically — no key needed:
append ACTUAL_BASE_URL=http://127.0.0.1:8080 to ~/.loki/.env, then:loki config set model.provider actual
loki config set model.default "INSTALLED_MODEL_NAME"
- Verify (reduced toolset — see context-window pitfall below):
loki chat -Q -q "Reply with exactly: LOCAL_OK" --provider actual -m INSTALLED_NAME -t file,web

Pitfalls
- reasoning_effort trap (handled by Loki since the first-class provider).
Actual's SGLang/vLLM backends accept only
none/low/medium/high/max;
xhigh/ultra used to fail with a cryptic
Expecting value: line 1 column 1 (char 0) (a wrapped HTTP 400). The
built-in provider clamps xhigh→high and ultra→max on the wire. If a
request still 400s this way on an old Loki, set a per-model cap:
agent.reasoning_overrides.<model>: high in config.yaml.
- Context-window overflow on small local models. Loki' default toolset
is ~26k tokens of schemas plus a ~9k-token system prompt. A model loaded
with a 32k context overflows before the first turn, and llama.cpp-family
servers emit a bare
data: [DONE] — Loki reports
Provider returned an empty stream with no finish_reason. This is NOT an
SSE bug. Fixes: restrict tools (-t file,web), load the model with a
larger n_ctx, or pick a >=64k-context model for the full toolset.
Upstream tracking: #51448 (do not file new issues; add evidence there).
Related but distinct: #65631 (HTTP-200 SSE carrying a 400), #56516
(reasoning-only streams).
- Download ids vs installed names.
actual models download takes
repo/QUANT and 409s without an explicit quantization;
actual models load takes the INSTALLED name from actual models list.
- Reasoning models returning empty content. GLM/Qwen reasoning variants
emit thinking in a separate
reasoning field and can burn a small
max_tokens entirely on reasoning. Give generous max_tokens before
assuming failure.
- Do not create a custom provider named
actual. Older setup guides
(pre first-class support) wrote providers.actual.* config blocks. On
current Loki the built-in provider wins the name; stale custom blocks
are ignored or conflict. Remove them and use the env vars + model.provider
flow above.
