Why teams in SEA choose SeaLink
Three things that matter for SEA teams.
Local payment options for SEA teams
Use familiar payment methods instead of workarounds that slow down onboarding. Stripe cards plus GrabPay, PromptPay, TrueMoney, GoPay, GCash, and MoMo payment links.
One invoice and clear records
Keep usage, billing, and invoice-ready records in one place. One Singapore bill for every model — one vendor, one reconciliation, one contract. Built for procurement.
Choose models by task, not by vendor
Browse by workflow — support, code, long docs, agents, and multilingual use cases. Organized by what you're building, not by which company trained the model.
Example workflows
Sample dataCommon workflows teams run with SeaLink
Examples of how teams route different workloads through one API and one account.
Cursor + Claude Code
Swap models with the same API pattern and minimal integration changes. Write with Claude Opus in Cursor, review diffs with Sonnet in Claude Code, generate tests with DeepSeek V4 Flash.
Typical models: Claude Sonnet 4.6 · Claude Haiku 4.5 · DeepSeek V4 Flash
OpenAI-compatible — change base_url, keep your code
SEA multilingual support
Run multilingual support flows with one API and procurement-friendly billing. Thai chat → Qwen3 Max. Vietnamese → Gemini Flash. Policy Q&A → Kimi K2 (1M context).
Typical models: Qwen3 Max · Gemini 3 Flash · Kimi K2
One Singapore invoice for every model
n8n / Dify agent pipeline
Use SeaLink with many OpenAI-compatible tools. Supported endpoints are documented in the docs. Orchestrate with tool-calling GPT-4o, execute with fast Haiku, summarize with Kimi K2.
Typical models: GPT-4o · Claude Haiku 4.5 · Kimi K2
Works with many OpenAI-compatible clients. Capabilities vary by provider.
Workflows above are common usage patterns observed by the SeaLink team, not specific customer case studies. Model recommendations based on latency, price, and SEA-fit assessment as of May 2026.
