Bug Description
GPT 5.6 Luna model via OpenCode Go provider fails with an encrypted content
verification error. The upstream request cannot decrypt or parse the response.
Error Message
AI_APICallError: Error from provider (Console Go): Upstream request failed:
invalid_encrypted_content The encrypted content gAAA...kifQ could not be
verified. Reason: Encrypted content could not be decrypted or parsed.
Steps to Reproduce
- Subscribe to OpenCode Go
- Connect via
/connectcommand - Select
opencode-go/gpt-5.6-lunamodel - Send any prompt
- Error occurs on response
Expected Behavior
Model should respond normally like other Go models (e.g., mimo-v2.5-pro works fine).

- OpenCode version: 1.18.21

This issue might be a duplicate of existing issues. Please check:
gpt-5.6-lunareturns empty response / 403 error with OpenCode Go API — same model, same provider, same symptom of failure while other models (e.g. deepseek-v4-pro) work fineIf your issue is the same as one of these, please add a comment there instead so the discussion stays in one place.

I get the same error, but with Opencode Zen, using the gpt5.6-sol model, with high reasoning.
Im using pi as my agent, v0.84.3, on Linux.
Error: OpenAI API error (400): {"param":null,"type":"invalid_request_error","message":"Error
from provider (Console): Upstream request failed: [invalid_encrypted_content] The encrypted
content for item rs_<some_Code> could not be verified.
Reason: Encrypted content could not be decrypted or parsed."}

Thanks for the report! OpenCode 2.0 is now out and development is focused on V2, so we're closing issues filed against OpenCode 1. Please upgrade (
opencode upgrade --major, details: https://anoma.ly/notes/opencode-2-0), and if this is still relevant on 2.0, reopen this issue or open a new one with your 2.0 version.— from 𝕺𝖕𝖊𝖓𝕮𝖔𝖉𝖊
