manifest v6.18.0

Auto-fix now works on self-hosted installs

Auto-fix repairs failing LLM requests before your fallback chain runs. When a provider rejects a request with a repairable error such as a malformed body, a renamed model, or an invalid parameter, Manifest sends the failed request to its healing service, receives a patched version, and resends it once. Until now this only worked on Manifest Cloud. Starting with v6.18.0 it works on self-hosted installs with zero configuration.

How to enable it

Upgrade to 6.18.0, then turn Auto-fix on per agent from the Settings page. The dashboard also shows a card listing agents that do not have it yet. It is off by default and requires a one-time consent per install.

docker pull manifestdotbuild/manifest:6.18.0

What this sends to our servers

Auto-fix is a hosted service. To repair a request, your install sends the failing request, including its message content, together with the provider's error response, to the Auto-fix service. Your install is identified by an anonymous install id. Provider API keys and OAuth tokens are never sent. The details are in the privacy policy and the terms.

How to turn it off

You can disable Auto-fix at any time per agent from the dashboard, or globally by setting AUTOFIX_GLOBAL_ENABLED=false. With that variable set, your install makes no calls to the Auto-fix service at all.

✨ Minor Changes

• f9eb3d8: Enable hosted Auto-fix for self-hosted installs: one-time consent with an option to turn it on for every existing agent, identified by the anonymous install id.
• 1e4cac8: Add opt-in Provider Attempt message recording with tenant-scoped durable filesystem or S3-compatible storage.

🐛 Patch Changes

• 1b633b6: Fix horizontal overflow in request drawer: error, autofix and fallback context cards now span full width, long error messages wrap instead of scrolling horizontally, and the tabs bar uses a muted background.
• 59f0e37: Enable automatic prompt caching for Anthropic API keys and OpenRouter Claude models.
• 205e25c: Auto-fix retries a healed model on the original provider transport when routing cannot resolve it (stale tenant model cache), instead of synthesizing a 502
• 31eaa75: Auto-fix always closes the evidence loop with Phoenix: a retry that dies mid-flight is reported as a synthetic 499 instead of leaving the heal attempt pending, and a dropped outcome report is resent before giving up
• f299e4b: Route Bedrock OpenAI and Anthropic models through their compatible Responses and Messages API surfaces.
• d040011: Stop blocking /billing/status and free-tier admission on the historical request-usage baseline scan; return the live counter immediately and finish the baseline in the background. Dashboards no longer wait on billing at all: the plan is resolved once at login via the new light GET /api/v1/billing/plan and read synchronously, so Overview, Global Overview, and the Requests log fetch each chart exactly once at the right range.
• 42a750b: Open routing model pickers from cached provider models and refresh stale catalogs only once per browser session each day.
• 95c17cf: Cache provider usage aggregates and coalesce live dashboard refreshes.
• f8cbfd8: Classify Anthropic subscription extra-usage errors as billing without sending them to Auto-fix.
• 89de9cd: Keep the routing page mounted while refreshed model data loads.
• 060b42b: Preserve GPT-5.6 reasoning summaries on inbound Chat Completions: map the standard reasoning_effort param onto the Responses reasoning object (with summary: auto) for OpenAI endpoints so the model actually reasons, prefix-match Responses reasoning-summary delta events instead of an exact-name allowlist, and backfill reasoning_content from the terminal response.completed/response.incomplete output when no summary deltas streamed.
• fb8beb2: Prepare DeepSeek reasoning tool turns once before each provider attempt.
• 6ac0908: Keep subscription model availability scoped to provider discovery and curated model lists.
• 3ed45a4: Enable message recording by default for newly created harnesses without changing existing harness settings.
• e56afee: Forward explicit uncatalogued models to connected providers so real model errors can reach Auto-fix.
• b4f85dd: Load paginated requests before aggregating attempts and refresh exact totals separately.
• 01a6966: Keep provider-cooldown skips and successful fallbacks as separate ordered Attempts in Request timelines.
• 934416d: Reject billing-enabled Cloud startup when request quota and process timezones differ.
• b6b5db5: Add a Gemini Free provider with Gemini-scoped keys and a reusable managed free-provider
  configuration. Use the existing managed gateway by default.
• ca18aad: Prevent headerless Codex subscription requests from sharing token-wide cache affinity.
• fa15665: Preserve native Responses and Anthropic Messages requests until cross-protocol conversion is required.
• 6d49e02: Record provider cache-write usage consistently across response formats.
• 06b0715: Make Auto-fix available to every tenant and retire the early-access waitlist.
• cdb9028: Preserve OpenRouter input and output modalities during model discovery.
• ecc29b6: Preserve redacted structured provider error details in proxy responses.
• 04710be: Simplify model parameter requests with a prefilled GitHub issue.
• 538d021: Improve request message drawer: markdown rendering, JSON syntax highlighting, gear icon for tool calls, wider drawer, Tools tab shows called and available tools separately.
• e4b6e6c: Remove the legacy Auto-fix tenant rollout columns after general availability.
• bd4b560: Honor requested model routes on the Anthropic Messages endpoint.
• d1d2ea7: Scope proxy replay caches and routing momentum to their owning tenant and agent.
• 4c42c24: Scope provider prompt cache affinity to explicit tenant and agent sessions.
• eaa4026: Show actual Provider Attempt tool calls instead of available tool definitions in recorded message details.
• 3f7f7cf: Show complete Gemini request messages, including system instructions.
• 1ee0634: Show recorded Gemini streaming responses in Provider Attempt message details.
• a0834db: Record Manifest-authored routing failures, including provider cooldown skips, as failed Attempts so the Request drawer shows the full routing chain.
• df19e6e: Keep the routing model picker open while refreshed model data loads.
• 064e462: Keep reasoning_content on OpenCode Zen requests. The reasoning dialect is now decided by the models.dev reasoning capability instead of a model-family regex, so Zen's DeepSeek and codename reasoning models replay their thinking while Claude/GPT/Gemini/Grok slugs keep stripping it.
