Kiro AI sebagai Backend¶

Claude Sonnet 4.5 unlimited gratis. Best free option per Mei 2026 buat agent yang butuh model bagus.

Apa itu Kiro¶

Kiro adalah AI coding assistant dari AWS (launched 2025). Awalnya untuk IDE/coding, tapi sekarang exposed API-nya bisa diakses lewat 9Router.

Yang lo dapet (per Mei 2026):

Claude Sonnet 4.5 — flagship Anthropic, kualitas top tier
Claude Haiku 4.5 — versi cepat & murah Claude
GLM-5 — Zhipu's flagship, comparable to GPT-4
MiniMax M2.5 — fast Chinese model
Qwen3 Coder Next — Alibaba's coding-focused
DeepSeek 3.2 — strong reasoning model

Semua unlimited gratis. Ga ada quota harian, ga ada API key paid, ga ada credit card.

Kenapa Kiro¶

Vs OpenAI API:

	OpenAI gpt-4o	Kiro (Claude 4.5)
Cost	$2.50/$10 per 1M token	FREE
Quality	Sangat bagus	Top tier (Claude lebih kuat di reasoning + code)
Rate limit	Tier-based	Reasonable per-account
Setup	API key	OAuth login

Vs OpenRouter free models:

	OpenRouter free	Kiro
Models	Llama, Mistral (free tier)	Claude Sonnet 4.5
Quality	Decent	Premium
Reliability	Sometimes rate-limited	Stabil
Cost	FREE (limited)	FREE (unlimited)

Tradeoff Kiro: - Latency sedikit lebih tinggi (kadang ada queue) - Provider bisa change policy anytime (Microsoft/AWS bisa start charge) - OAuth required (vs Naked API key di provider lain)

Buat agent personal: Kiro best choice kalo lo udah host 9router.

Setup Kiro lewat 9Router¶

1. Buka dashboard 9Router¶

http://localhost:20128  (atau http://<vps-ip>:20128 lewat SSH tunnel)

2. Navigate ke Providers¶

Sidebar → Providers → Add Provider → pilih Kiro AI.

Opsi:

AWS Builder ID (recommended): bikin gratis di https://profile.aws.amazon.com/, ga butuh credit card
AWS IAM Identity Center: kalo lo punya AWS organization
Google: pake akun Gmail/Google Workspace
GitHub: pake akun GitHub

Klik tombol login → browser open OAuth flow → authorize → kembali ke dashboard.

4. Verify connected¶

Status should show Connected + lampu hijau. Models harus appear:

kr/claude-sonnet-4.5
kr/claude-haiku-4.5
kr/glm-5
kr/MiniMax-M2.5
kr/qwen3-coder-next
kr/deepseek-3.2
kr/auto (auto pick best available)

5. Test dari CLI¶

curl -X POST http://127.0.0.1:20128/v1/chat/completions \
  -H "Authorization: Bearer $FREEMODEL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "kr/claude-sonnet-4.5",
    "messages": [
      {"role": "user", "content": "Halo Claude, siapa lo?"}
    ]
  }'

Expect response JSON dengan Claude reply.

Integrate ke agent (Kai)¶

Update ~/agent/.env:

OPENAI_API_KEY=<9router API key>
OPENAI_BASE_URL=http://127.0.0.1:20128/v1
OPENAI_MODEL=kr/claude-sonnet-4.5

Atau pakai kr/auto kalo lo mau biarin 9router decide:

OPENAI_MODEL=kr/auto

Restart bot:

sudo systemctl restart kai-bot

Test di Telegram. Response harus lebih bagus (Claude Sonnet 4.5).

Tips optimal pake Kiro¶

1. Pilih model sesuai task¶

kr/claude-sonnet-4.5 — default, paling balance (quality + speed)
kr/claude-haiku-4.5 — fast simple tasks (chat, summarize)
kr/glm-5 — alternative kalo Claude lagi slow
kr/auto — let router decide

Dynamic switching di kode:

def select_model(task_type):
    routing = {
        "chat": "kr/claude-haiku-4.5",      # fast & cheap
        "code": "kr/qwen3-coder-next",       # coding
        "reason": "kr/claude-sonnet-4.5",   # complex reasoning
        "default": "kr/auto"
    }
    return routing.get(task_type, routing["default"])

2. Backup provider¶

Walaupun Kiro unlimited, kadang queue/down. Set fallback di 9Router:

Dashboard → Providers → Priority order: 1. Kiro AI (primary) 2. OpenCode Free (fallback) 3. GLM (cheap fallback)

Kalo Kiro down, auto switch ke OpenCode Free, ga break flow.

3. Multi-account Kiro¶

Bikin 2-3 akun Kiro (AWS Builder ID gratis, satu email satu akun):

Dashboard → Providers → Kiro → Add Account.

9Router round-robin antar akun. Reduce queue risk.

4. Token efficiency¶

Kiro count token, walau unlimited. Tetap optimize:

Concise system prompt
Sliding window history (last 20-30 msg)
RTK Token Saver (auto, by 9Router)

Troubleshooting¶

"Authentication required" saat first call¶

Token expired. Dashboard → Providers → Kiro → Re-authenticate.

Auto-refresh harusnya jalan, tapi kalo failed:

# Cek log 9router
sudo journalctl -u 9router -n 50 | grep -i kiro

Response lambat (>10 detik)¶

Possible: 1. Kiro lagi queue (high traffic) → switch ke kr/auto, biar router decide 2. Network VPS lambat → cek ping ke endpoint Kiro 3. System prompt terlalu panjang → kompres

"Quota exceeded" (rare)¶

Walau "unlimited", masih ada soft rate limit. Solusi: 1. Multi-account 2. Backup provider (OpenCode Free, GLM) 3. Tunggu 5-10 menit

Model tertentu ga muncul di list¶

Login Kiro re-do, atau model spesifik perlu unlock.

Dashboard → Providers → Kiro → Models — toggle yang lo mau.

Account management¶

Bikin AWS Builder ID¶

https://profile.aws.amazon.com/
Create account → email + password
Verify email
Done. Free, no credit card.

Multiple accounts (advanced)¶

Strategi: bikin 3-5 AWS Builder ID dengan email berbeda (Gmail + alias, atau email provider lain).

agent-kiro-1@gmail.com
agent-kiro-2@gmail.com
agent-kiro-3@gmail.com

Add semua ke 9Router. Round-robin = 5x effective capacity.

⚠️ Term of Service Kiro mungkin restrict multi-account untuk individual user. Cek ToS terbaru sebelum scale.

Privacy & security¶

Yang Kiro lihat: - Setiap chat lo (prompt + response) di-log di Kiro side - Mereka pake untuk training? Kemungkinan ya (free service = data is product)

⚠️ Jangan paste: - Credentials (token, password, private key) - Komunikasi pribadi orang lain - Code proprietary perusahaan yang under NDA

Kalo lo butuh privacy, pake: - Self-host model (ollama, llama.cpp) - Paid API dengan no-train policy (OpenAI API enterprise, Anthropic API)

Comparison: Kiro vs alternatives¶

Backend	Cost	Quality	Setup	Privacy
Kiro (Claude 4.5)	FREE	⭐⭐⭐⭐⭐	Easy (OAuth)	Logged
OpenAI gpt-4o API	$$$	⭐⭐⭐⭐⭐	Easy (API key)	Better (paid)
OpenAI gpt-4o-mini API	$	⭐⭐⭐⭐	Easy	Better
Anthropic Claude API	$$$	⭐⭐⭐⭐⭐	Easy	Better
Groq (Llama 70B)	FREE/$	⭐⭐⭐⭐	Easy	Logged
Self-host Llama	FREE (compute)	⭐⭐⭐⭐	Hard	Local
OpenCode Free	FREE	⭐⭐⭐⭐	Easiest	Logged
OpenRouter (free tier)	FREE	⭐⭐⭐	Easy	Logged

Saran:

Production agent personal → Kiro (best free, best quality)
Privacy-sensitive → Self-host atau paid API
Bot kecil ringan → OpenCode Free atau OpenRouter free

Lebih jauh dari Kiro¶
