The non-streaming Anthropic path leaked OpenAI chat.completion bodies to
Claude clients when the upstream provider forces streaming (forced
SSE->JSON path): parseSSEToOpenAIResponse yields choices[] which Claude
Code cannot parse. Convert to Claude Messages shape for sourceFormat
CLAUDE in sseToJsonHandler.
Shared toClaudeMessageShape/openAICompletionToClaudeMessage moved to
translator/concerns/claudeShape.js to avoid circular import between
nonStreamingHandler and sseToJsonHandler. 5 new tests: sse-to-json
reassembly + Claude guard, plus existing anthropic-nonstream-shape
updated to import from the concern.
BUG: Anthropic client (sourceFormat=CLAUDE) hitting a claude-target provider
got a raw OpenAI chat.completion body on non-streaming requests. The
needsTranslation(CLAUDE,CLAUDE) gate is false when target===source, so the
translator never ran; a claude-transport executor replying OpenAI JSON
(opencode/big-pickle) leaked choices[]/prompt_tokens to the client, which
Anthropic SDKs cannot parse (no content[] blocks, no type:"message").
FIX: shape-aware guard toClaudeMessageShape() in nonStreamingHandler — when
sourceFormat is CLAUDE, convert any OpenAI-shape body to a proper Claude
message (type, content blocks with thinking/text/tool_use, stop_reason via
finish mapping, usage input/output tokens). Claude-shaped bodies pass through.
Also: strip <|im_end|>/<|endoftext|>/<|eot_id|> EOS sentinels from Claude
text deltas in openai-to-claude and kiro-to-claude translators — the upstream
EOS token leaks into the final text_delta (observed 'OK<|im_end|>').
Tests: anthropic-nonstream-shape.test.js (6: eos strip + shape guard incl
tool_calls→tool_use, pass-through, finish mapping). 28/28 related tests green.
Reproduce the MiMo Desktop login surface server-side so headless/Docker
deployments can link a Xiaomi account without the Desktop client. The
account session (passToken) is captured during the proxied login and
stored per connection.
- Five account clusters (cn/sgp/ams/ru/in): per-region mimo-server host
and SSO sid, unknown region falls back to sgp
- mimo-v2.6-pro/flash/pro-ultraspeed dual-route models: account-service
route when desktop credentials exist, cloud API (sk- key) otherwise;
drops obsolete mimo-x-*-preview ids
- Desktop ServiceTokenManager 2-phase handshake (single serviceLogin with
target sid, raw 64-bit nonce preserved), per-region session cache
- reasoning_effort bridged to output_config.effort; i18n runtime now
observes characterData mutations so React text rewrites get translated
- Security hardening on the login proxy: session travels only in the
httpOnly cookie (never in the URL), proxy branch requires dashboard
auth, authorization/proxy-authorization never forwarded upstream, and
upstream Set-Cookie is not replayed onto the app origin
Preserve request headers through the Vercel/Cloudflare/Deno relay.
- proxyFetch: normalize options.headers via Object.fromEntries before
spreading into the relay headers. Spreading a Headers instance yields
{} and silently dropped every entry (auth + content-type), which is why
the same pool worked on one path and failed on another.
- vercel relay: build the forwarded header object from req.headers.entries()
instead of new Headers(req.headers), avoiding edge-runtime normalization
of casing/duplicate keys that some providers reject.
Anthropic's API-level refusal (streaming classifier / ToS) ends the stream
with stop_reason "refusal", stop_details carrying the reason, zero output
tokens and no content blocks. Map refusal to content_filter in both
directions, surface stop_details.explanation as message text, and add
CLAUDE_STOP.REFUSAL to schema.
getUsageStats("all") shipped the entire usageHistory table to JS just to
refine lastUsed (~2s on 290K rows, on every statsEmitter update per SSE
listener). Bound the overlay to a 2-day indexed range scan; older entries
keep day-level lastUsed from usageDaily aggregates. Totals unaffected.
budgetToLevel now maps budgets > 80384 (midpoint of 32768/128000) to
"max" instead of clamping to "xhigh", so the top reasoning tier is
reachable from large budget_tokens requests.
OpenRouter serves TypeSafe Jev at POST /api/v1/systemone with the same
request/response shape, so it plugs into systemoneConfig directly with
model typesafe/jev-1.13. Mark the System One media kind isNew and
render a New badge on the sidebar kind item and the Media Providers
accordion when any visible kind is new.

Expose System One in the Media Providers sidebar accordion, set
kind to "systemone" on Jev models for ModelsCard filtering, wire
systemoneConfig into ProviderInfoCard, and configure GenericExampleCard
for interactive testing of decision models.

New /v1/systemone pass-through route for Jev decision models (jev-1.13,
jev-1.13-free) on OpenCode Zen and the free lane. Follows the media-route
pattern: systemoneConfig in the registry drives URL/headers, the handler
mirrors the embeddings account-fallback + usage flow, and the dashboard
gains a System One media-provider kind. No chat-pipeline changes.

Register mimo-v2.6-flash-free on opencode-zen (chat lane) with a v2.6

Map upstream Chat Completions usage to the Responses API shape and attach it to response.completed. Capture chunk.usage before the empty-choices guard so the usage-only trailer chunk survives, and defer completion to flushEvents() when usage is not yet known — only on the direct openai:openai-responses route, since a pivoted stream never reaches flushEvents. Fixes#3432.
- Track both weekly and 5-hour session buckets in parseWeeklyQuotaSummary,
distinguishing sliding-window limits from multi-day weekly limits
- Preserve disabled session buckets at 0% rather than dropping them when weekly limits are reached
- Target 5-hour session rows (not weekly rows) during family exhaustion reconciliation in getAntigravityUsage
- Suppress synthesized per-model duplicate rows in dashboard normalization when family summaries are present
- Add unit test coverage for multi-bucket extraction, reconciliation isolation, and dashboard deduplication
- Match code 110 (billing daily count exceeded) alongside 112/10605/pricingUrl
in isBillingBlock, parsing JSON safely and accepting numeric/string codes
- Accept numeric strings for statusCodeValue and object bodies in envelope peek
- Emit structured 403 quota error chunk instead of synthetic assistant text
when a billing envelope appears mid-stream
- Preserve upstream HTTP status in handleForcedSSEToJson when error chunk carries
a valid 400-599 status
- Add unit tests for code-110 detection, mid-stream billing envelopes, and false-positive guard
Strict OpenAI-compatible validators reject unknown assistant-message
fields: Groq 400 ("property 'reasoning_content' is unsupported"),
Mistral 422 ("extra_forbidden"), Cerebras 400 ("wrong_api_format").
Clients driving reasoning models (Hermes Agent, and anything following
the DeepSeek/Kimi convention) echo the previous turn's reasoning_content
on every assistant message, so from the second turn on every request to
these providers fails and a fallback combo silently skips them.
Add a dropMessageFields rule to paramSupport.js that strips
reasoning_content / reasoning / reasoning_details from assistant turns
for groq, mistral, and cerebras.
Cursor-hosted models (cu/composer-2.5, cu/cursor-grok-*, cu/default) returned
HTTP 200 with an empty turn, or hung, whenever a client sent tools.
- Fold system prompts into the current user message. custom_system_prompt
(RunRequest field 8) makes AgentService return an empty turn.
- Send ModelDetails (field 3); thinking variants (Composer, Grok, *-thinking)
return an empty turn when only requested_model (field 9) is set.
- Route tool-call history and declared tool schemas through AgentService:
encode OpenAI tools into mcp_tools (field 4), decode McpArgs and emit real
tool_calls with finish_reason tool_calls.
- Map Composer thinking / Grok thinking_delta (field 4) into visible content
instead of dropping the answer with the unsigned reasoning.
- Ack request_context without echoing MCP tools (double-advertise stalls the
HTTP/2 stream) and ack kv_server_message so the run proceeds.
- Reject IDE builtin execs instead of failing the turn, so the model can
continue with MCP tools or a text answer.
- Add google.protobuf.Value / MCP encoders and a FIXED64 branch to
encodeField in cursorProtobuf.js.
RTK now compresses the source-format body before translation for cursor only:
its translator rewrites role:tool into user XML, so the post-translate pass
missed those tool results. Every other provider keeps the post-translate pass
unchanged.
- Export aggregateComboCapabilities: union for vision/audio/search/pdf,
intersection for tools, primary-model for reasoning fields, min
contextWindow, max maxOutput
- Support nested combo resolution in aggregateComboCapabilities via
comboLookup with depth guard (max 6)
- Wire capability metadata to all /v1/models entries and combos
- Show aggregated ctx/max metadata line and capability badges on combo chips
- Pattern fixes: MiMo v2.5/omni reasoning, qwen max/plus vision, minimax m2.x vision
- Sync commandcode model catalog and add openai gpt-5.5
- Add unit tests for capability patterns and combo capability aggregation
Replace the retired api-inference.huggingface.co host with the Inference
Providers router (router.huggingface.co): imageConfig.modelMap resolves
Hub ids to provider-resolved ids, image-to-image models receive the
source image in inputs with the prompt under parameters.prompt, and a
new sttConfig wires the hf-inference ASR route. The image catalog grows
to 23 models, dead whisper-small is replaced by whisper-large-v3-turbo,
the unusable "language" param is dropped, and edit models declare the
edit capability so the dashboard offers a source image. Adds unit and
end-to-end coverage plus a model-id guard on custom endpoints.
Free-tier Zen models reject Responses requests with 403 FreeTierError
when client tools are present but the fingerprint quartet is missing.
Apply the fingerprint tools to every OpenCode request, canonicalise
case variants of the quartet (Bash->bash) without duplication, and
restore the caller's original spellings on the response side via a
request-local WeakMap threaded through the existing toolNameMap.
## Features
- **Xiaomi MiMo**: merge MiMo Desktop support into `xiaomi-mimo` with dual auth (API key + Desktop/OAuth session), Preview models support, and encrypted-callback OAuth flow
- **Claude Code**: add 1M-context toggle (`[1m]` marker) and drive `CLAUDE_CODE_AUTO_COMPACT_WINDOW` directly from the dashboard
- **Models**: add DeepSeek-V4.1-Flash to DeepSeek provider, CodeBuddy-Intl, and Ollama (`deepseek-v4.1-flash:cloud`); enable `low`..`max` reasoning effort levels and vision capability for DeepSeek-V4.*
- **i18n**: integrate Persian (fa) translation
## Fixes
- **OpenCode / OpenCode Go**: resolve 403 `FreeTierError` and 429 rate limits with canonical session format, valid User-Agent, and stable upstream session reuse; force stream and declare `forceStream` for free-tier SSE aggregation; cloak decoy tools, normalize Muse Free tool choice, and strip prior reasoning items on Responses models; route Union Alpha via Messages API
- **Kiro**: preserve underscores in tool names (`mcp__server__tool`) and restore client tool names in responses; use neutral placeholder for tool-result-only turns; forward tool-result images
- **Stream**: report aborts after HTTP 200 in-band (per-format error frames) instead of closing silently
- **Command Code**: preserve images and `reasoning_effort` on `/alpha/generate`; retry transient stream errors and avoid fake stop chunks; add Quota Tracker support
- **Zed**: harden OAuth lifecycle (preserve `systemId`, renew proxy timeout), support live model resolution, and lower display priority in OAuth list
- **Antigravity**: scope cached thought signatures to model family; strip Claude Code billing headers from system prompts; sanitize Hermes system identity
- **Codex**: route bare `codex-auto-review` requests to the Codex provider (#4135)
- **Auth**: do not cool down an account for request-scoped 4xx errors
- **Usage**: improve DeepSeek credit balance display as currency credit instead of 0/total quota bar
- **Model Catalog**: scope synced catalog to gateways and declare vision capabilities for DeepSeek V4.1-Flash IDs
- Force stream:true and cloak decoy tools (bash, read) for OpenCode free tier
- Support connection testing for opencode in testUtils
- Expand error message slice limits in auth and ping to preserve workspace link
- Add concise China region link chip in provider detail page
Co-Authored-By: Claude Code <noreply@anthropic.com>
- executors/zed.js: use exact wire values (anthropic, open_ai, google, x_ai)
and strip incompatible Vertex safetySettings on the Google path
- shared/zedAuth.js: robust callback query parsing, reject garbage PKCS#1 v1.5
decryptions, and thread proxyOptions when fetching LLM tokens
- oauth: preserve systemId across authorize/register/exchange lifecycle,
renew proxy idle timeout on reuse, and ignore non-callback localhost requests
- shared/OAuthModal.js: track owned proxy in flowRef and stop at most once
- api/providers/[id]/models: add connection-scoped live Zed model resolver
- registry: unhide provider in dashboard
- tests: add unit coverage for wire format, native auth, and live models
Do not trigger account cooldown or fallback for request-scoped 4xx errors that match no account rules so healthy credentials are not locked out for context length or validation errors.
OpenCode Free returns HTTP 400 for muse-spark-1.3-contributor-free when tool_choice is non-auto. Declare forceAutoToolChoiceModels quirk and normalize explicit tool_choice to auto.
Strip prior-turn type: reasoning items and encrypted_content fields from body.input on Muse Spark Responses endpoints in OpenCode and OpenCode Go executors to avoid HTTP 400 errors across rotated proxy accounts.
Do not collapse consecutive underscores in uniqueName so mcp__server__tool is sent intact to Kiro, attach reverse map on request translation, and restore client tool names in responses.
Replace the literal 'continue' placeholder on tool-result-only user turns with 'Tool results provided.' to prevent models from treating it as a new user instruction.
Forward images inside tool_result to OpenAI and Kiro upstreams via following user messages, restore original client tool names on Kiro responses via _toolNameMap, and preserve thinking display settings across translations.
Follow-up to the canonical-session fix: with no explicit session,
every request minted a fresh x-opencode-session, and upstream free-tier
quota is accounted per session. That burns through quota and surfaces
as 429 FreeUsageLimitError with growing reset-after delays, while the
real CLI reuses one long-lived session per conversation.
- Stable canonical session per downstream identity (connectionId, else
auth-header hash, else shared default), evicted after
MEMORY_CONFIG.sessionTtlMs like the other session stores.
- Deterministic x-opencode-request per message (stable across retries,
like the CLI user message id); valid downstream ids preserved.
- 6 more unit tests (22 total).
OpenCode upstream validates free-tier requests: User-Agent must be opencode/<version> (>= 1.17.0) and x-opencode-session must match canonical ses_ format. Default OPENCODE_UA to opencode/1.18.31, generate canonical descending session IDs, provide deterministic foreign session translation, and isolate credentials per-request.
Route union-alpha to /zen/v1/messages with targetFormat claude, add anthropic-version header, and register model capabilities (vision, 262K context, 131K max output).
