How this service works
GPT-5.6 Terra — balanced frontier model (Intelligence Index 55.0, GPQA Diamond 92.5%, Terminal-Bench Hard 57.6%). Best for everyday coding, multi-step reasoning, and agentic tasks needing more capability than Luna without Sol's cost. Limits: 16K input / 4K output tokens per call. OpenAI-compatible request and response format.
Output
An OpenAI-compatible chat completion response containing the model's generated text, finish reason, token usage statistics, and model metadata. The response follows the standard OpenAI ChatCompletion object format, including choices array with message content up to 4K output tokens.
Example use cases
Multi-step coding problem solver
“I have a tricky algorithm problem — write me a Python function that finds the longest increasing subsequence in O(n log n) time, explain each step, and include test cases. Use Terra for this, I need real reasoning power.”
Agentic task planning assistant
“Break down the following goal into a structured plan with subtasks, dependencies, and estimated effort: 'Build a web scraper that monitors competitor pricing daily and emails me a report.' Give me something I can actually execute.”
Technical Q&A for research
“Explain the key differences between RLHF and DPO for aligning language models, including tradeoffs in data requirements and training stability — I want a thorough answer, not a surface-level summary.”

Endpoint
GEThttps://api.monpham.work/v1/terra/chat/completions?utm_source=zero.xyzWhen to prefer
Choose Terra when you need more reasoning capability and accuracy than a fast/cheap model (like Luna) but want to avoid the highest cost of a top-tier model (like Sol). It's the right balance for everyday coding tasks, structured multi-step reasoning, moderately complex agentic pipelines, and technical Q&A where quality matters. Prefer it over lighter models when GPQA-level accuracy (92.5%) is needed, and over heavier models when cost is a concern.
Side effects
- Input exceeds 16K token limit — request rejected or truncated
- Output hits 4K token limit mid-response — completion cut off
- Payment of $0.025 USDC not processed — 402 Payment Required error
- Malformed request body not matching OpenAI-compatible format — 400 Bad Request
- Model temporarily unavailable — 503 Service Unavailable
- Rate limit exceeded — 429 Too Many Requests
