Skip OpenAI messages-dispatch gpt-5.x defaults for OpenCode groups and
composite OpenCode targets. Filter unpriced claude-* billing candidates,
estimate count_tokens locally, sanitize body session IDs before setting
X-OpenCode-Session, and treat Zen 402 as recoverable payg cooldown.
Stop rewriting the inbound body before protocol routing so account
model_mapping applies once and usage_logs.model stays the client name.
Apply account model_mapping to the request body before OpenCode
protocol routing so /v1/responses, /v1/chat/completions, and
/v1/messages all send the mapped ID as the real upstream model.
Keep the internal platform ID opencode_go. Product surface is OpenCode
with account_mode zen|go, model-aware routing across Chat Completions,
Responses, and Anthropic Messages, and X-OpenCode-Session derived from
prompt_cache_key / metadata.user_id so prompt cache can hit.
Unmatched models fall back to /v1/chat/completions. Related to #6742.
Accept service_tier=ultrafast on the OpenAI/Codex gateway, advertise it
on GPT-5.6 Sol in the Codex model catalog, and include it in ChatGPT
OAuth routing hints so Codex clients can select Ultrafast.
Moonshot pay-as-you-go and Kimi For Coding both expose native
/v1/responses. Stop converting Kimi Responses traffic to Chat
Completions, and treat Kimi like DeepSeek for protocol selection while
keeping /v1/responses URL construction.
OpenAI/Composite groups can now reject requests that exceed the max
reasoning effort instead of always rewriting them down to the ceiling.
Existing groups keep the previous auto-downgrade behavior.
Allow OpenAI/Composite group mappings to match by exact model name,
prefix, or suffix. Empty type and model still apply to every model.
The admin form groups multiple request-to-forward pairs under one
type+model scope.
Users only see the reasoning effort they requested. Admins still see
the requested value plus the forwarded mapped value, matching the
model column's requested vs upstream split.
