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.
Google released Gemini 3.7 Flash on 2026-08-13. Register it alongside 3.8
using the same shape as the existing 3.6 entries: bare id plus the
Antigravity -high/-low/-medium/-tiered thinking tiers, the model catalog,
the custom-mapping passthroughs, fallback pricing and the tier alias
normalizer.
Pricing matches 3.8 at $0.75 input / $3.75 output / $0.075 cached input
per MTok. Both are promotional through 2026-12-31 and double on
2027-01-01; the constants note this.
Also corrects the 3.8 catalog timestamps to the documented GA dates.
Google released Gemini 3.8 Flash on 2026-09-02. Register the model and its
Antigravity thinking tiers the same way Gemini 3.6 Flash is registered:
- DefaultAntigravityModelMapping: bare id plus -high/-low/-medium/-tiered
- geminiModels catalog exposed through /antigravity/v1/models
- ensureAntigravityDefaultPassthroughs so accounts with a custom
model_mapping still resolve the new ids
- fallback pricing and the thinking-tier alias normalizer, so the tiers
share the base model price card instead of failing pricing lookup
Fallback rates are Google's published prices: $0.75 input / $3.75 output /
$0.075 cached input per MTok. These are promotional through 2026-12-31 and
double on 2027-01-01; the constant carries a note to that effect.

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.
Update model mapping target for claude-haiku-4-5 and
claude-haiku-4-5-20251001 from claude-sonnet-4-5 to claude-sonnet-4-6.
Includes migration script, default constants, and test updates.
Consolidate two separate channel types (bedrock + bedrock-apikey) into
a single "AWS Bedrock" channel. Authentication mode is now distinguished
by credentials.auth_mode ("sigv4" | "apikey") instead of separate types.
Backend:
- Remove AccountTypeBedrockAPIKey constant
- IsBedrock() simplified; IsBedrockAPIKey() checks auth_mode
- Add IsAPIKeyOrBedrock() helper to eliminate repeated type checks
- Extend pool mode, quota scheduling, and billing to bedrock
- Add RetryableOnSameAccount to handleBedrockUpstreamErrors
- Add "bedrock" scope to Beta Policy for independent control
Frontend:
- Merge two buttons into one "AWS Bedrock" with auth mode radio
- Badge displays "Anthropic | AWS"
- Pool mode and quota limit UI available for bedrock
- Quota display in account list (usage bars, capacity badges, reset)
- Remove all bedrock-apikey type references
- Add migration 060 to update model_mapping for all antigravity accounts
- Remove gemini-3-pro-image and gemini-3-pro-image-preview mappings
- Add gemini-3.1-flash-image and gemini-3.1-flash-image-preview mappings
- Update frontend usage window to show GImage for new model
- Update isImageGenerationModel to support new model
- Remove Gemini platform exclusion from model restriction UI in
Create/Edit account modals (Gemini now supports model_mapping)
- Remove outdated Gemini model passthrough info cards
- Add model_mapping field to GeminiCredentials type
- Extend warmup request interception toggle to Antigravity platform
- Remove redundant try/catch in API key account creation
- Remove noisy gateway.request_completed debug log
- Reorganize Gemini model mapping sections in constants.go
- Add claude-sonnet-4-6 to default Antigravity model mapping
- Add antigravity_extra_retries default value in config
- Add cache-dependency-path to CI setup-go for faster builds
- Simplify vitest config to avoid vite plugin compatibility issues
Implements announcements end-to-end (admin CRUD + read status, user list + mark read) with OR-of-AND targeting. Also breaks the ent<->service import cycle by moving schema-facing constants/targeting into a new domain package.
