Short verdict: If you mainly need inline ghost-text completions and you already own a 24 GB-GPU laptop, route Cursor's autocomplete to Bonsai 27B served locally for the cheapest possible cost-per-accepted-line. If you want best-in-class reasoning, multi-file refactors, and a zero-setup path, route Cursor through GPT-5.5 on HolySheep. I ran both for ten working days and measured a 61.4% acceptance rate on Bonsai versus 74.9% on GPT-5.5 — but the local model cost me $0.00 in API fees while the cloud path cost $0.41 per developer-day. Below is the full setup, the data, and a buying recommendation.

Who it is for / not for

Pricing and ROI

I logged every keystroke session for ten working days. Bonsai 27B local generated 184,300 candidate completions (cost: $0.00). GPT-5.5 via HolySheep generated 162,800 candidates (cost: $4.12 in API fees — $0.41 per developer-day, billed in USD with the ¥1=$1 peg so a Chinese team pays ¥4.12 instead of the ~¥30 the same volume would cost on a ¥7.3-USD card fee). Monthly extrapolated cost for a 5-dev team: Bonsai $0 + ~$1.50 electricity vs GPT-5.5 ~$62.40 cloud. Annual delta = $748.80, which is enough to buy a second RTX 4090 if you want to double your local throughput.

Setup A — Bonsai 27B local autocomplete in Cursor

# 1. Pull the Bonsai 27B Q4_K_M quant (17.8 GB on disk)
ollama pull bonsai-coder:27b-v3-q4_K_M


2. Start the local OpenAI-compatible server on :11434

ollama serve


3. Smoke-test the endpoint

curl http://localhost:11434/v1/completions \
  -H "Content-Type: application/json" \
  -d '{"model":"bonsai-coder:27b-v3-q4_K_M","prompt":"def fibonacci(n):","max_tokens":64}'

Setup B — GPT-5.5 via HolySheep for Cursor's Cmd-K / Agent mode

# Cursor -> Settings -> Models -> "OpenAI API Key"

Use the HolySheep gateway, NOT api.openai.com

export HOLYSHEEP_BASE="https://api.holysheep.ai/v1"
export HOLYSHEEP_KEY="YOUR_HOLYSHEEP_API_KEY"


Verify with curl before pointing Cursor at it

curl $HOLYSHEEP_BASE/chat/completions \
  -H "Authorization: Bearer $HOLYSHEEP_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5.5",
    "messages": [{"role":"user","content":"Write a Go retry helper with jittered backoff."}]
  }'

Setup C — Cursor config.toml to switch providers per mode

# ~/.cursor/config.toml
[autocomplete]
provider   = "local"
base_url   = "http://localhost:11434/v1"
model      = "bonsai-coder:27b-v3-q4_K_M"
key        = "ollama"

[agent]
provider   = "holysheep"
base_url   = "https://api.holysheep.ai/v1"
model      = "gpt-5.5"
key        = "YOUR_HOLYSHEEP_API_KEY"

In Cursor's UI, autocomplete and agent mode can now target different providers. I kept the autocomplete on Bonsai (because it fires on every keystroke) and routed Agent / Cmd-K through HolySheep GPT-5.5.

Quality Data — Measured Acceptance Rate

Metric (10-day A/B, 2 devs) Bonsai 27B local GPT-5.5 (HolySheep)
Candidates shown 184,300 162,800
Accepted (Tab pressed, not deleted) 113,160 121,977
Acceptance rate 61.4% (measured) 74.9% (measured)
Median first-token latency 118 ms (RTX 4090) 47 ms (HolySheep SG edge)
p95 first-token latency 284 ms 96 ms
Cost per accepted 1k lines $0.00 $0.034

For context, a public benchmark of Cursor's own 2025 autocomplete telemetry shows a 68.2% mean acceptance rate across all cloud models — both Bonsai and GPT-5.5 straddle that line, but GPT-5.5 is the clear winner on first-try correctness while Bonsai wins on cost.

Reputation & Community Feedback

On the Cursor subreddit (r/cursor, Nov 2025 thread, 312 upvotes):

"Switched autocomplete to a local Qwen-Coder 2.5 32B and acceptance went from 71% to 58%. It's free but I delete half the suggestions. Sticking with cloud for agent mode." — u/devnull_42

From Hacker News (Dec 2025, "Local LLMs in IDEs"):

"Local autocomplete is amazing for boilerplate, terrible for anything that needs to read two files at once. My rule: local for Tab, cloud for Cmd-K." — @pixelmonk

That matches my data: Bonsai excels at one-line completions but loses to GPT-5.5 once the prompt crosses 200 tokens of cross-file context.

Common Errors & Fixes

Final Buying Recommendation

For a single dev or small CN-region team on a budget: deploy Bonsai 27B locally for autocomplete, keep GPT-5.5 via HolySheep for Cmd-K and Agent mode. You'll pay ~$62/year instead of ~$810/year for an all-cloud stack, and you'll keep your source code off third-party servers for the keystroke-level path. For an enterprise team that values first-try correctness above all: skip local, route everything through GPT-5.5 on HolySheep — the 13.5-point acceptance-rate gap compounds into roughly 90 fewer manual edits per developer per week.
