Go 1.26.x build fails with sonic v1.14.1 due to missing GoMapIterator type. Upgrading to v1.15.0 restores build compatibility on modern Go toolchains. Same fix as PR caidaoli#37 (isabst). Verified with go 1.26.1 darwin/arm64 and linux/amd64.
Kiro Pro subscription already supports these models (verified via 'kiro-cli chat --list-models'), but kiro2api's ModelMap was missing the entries, causing 'model not found' errors for modern Claude models. Changes: - Add claude-opus-4.5, claude-opus-4.5-20251101 → claude-opus-4.5 - Add claude-opus-4.6, claude-opus-4.6-20260205 → claude-opus-4.6 - Add claude-sonnet-4.6, claude-sonnet-4.6-20260205 → claude-sonnet-4.6 - Upgrade claude-haiku-4.5-20251001 from 'auto' to exact mapping - Add claude-haiku-4.5 short alias Value format follows kiro-cli's short ID (e.g. 'claude-opus-4.6'), which CodeWhisperer accepts alongside the legacy CLAUDE_XXX_V1_0 format. Relaxed test format validator to allow all three formats. Validated end-to-end with real Kiro Pro account: - Non-streaming opus-4.6: PASS - Streaming sonnet-4.6: PASS (full Anthropic SSE event chain) - Non-streaming haiku-4.5: PASS
When kiro2api runs behind an upstream LLM gateway (Sub2API, OneAPI, LiteLLM,
etc.), two deployment conveniences are common needs:
1. BIND_HOST — restrict the listening address. Default is all interfaces
(':<port>'). Set 'BIND_HOST=127.0.0.1' to only accept connections
from the same host (production hardening when behind a gateway).
2. DISABLE_AUTH — skip kiro2api's own API-key middleware on /v1/*. Useful
when the upstream gateway already authenticates callers and transparently
forwards their api-key header (which won't match KIRO_CLIENT_TOKEN).
Emits a warning at startup so operators don't accidentally expose the
server without auth.
Both features default to the previous behavior (listen on all interfaces,
require KIRO_CLIENT_TOKEN) so existing deployments are unaffected.
Example gateway-behind deployment .env:
BIND_HOST=127.0.0.1
PORT=8081
DISABLE_AUTH=true
KIRO_AUTH_TOKEN='[{"auth":"IdC","refreshToken":"...","clientId":"...","clientSecret":"..."}]'

Summary
Three related improvements to make kiro2api usable with modern Claude models (Opus 4.5/4.6, Sonnet 4.6, Haiku 4.5) and easier to deploy behind upstream LLM gateways.
Kiro Pro already supports all current Claude models — verified via
kiro-cli chat --list-models:but kiro2api's
ModelMapinconfig/config.golists only Sonnet-4/4.5, 3.7-sonnet, 3.5-haiku plus a partialautofallback for Haiku 4.5. Requests for Opus 4.6 etc. currently return "model not found".Commits
chore(deps): upgrade sonic to v1.15.0 for Go 1.26 compatibility
Same fix as upgrade sonic to v1.15.0 for go1.26 build #37 (isabst) —
sonic v1.14.1fails to build on Go 1.26.x due to missingGoMapIterator. Included here to keep the branch self-contained (CI on Go 1.26 fails otherwise). Happy to drop if upgrade sonic to v1.15.0 for go1.26 build #37 lands first.feat(models): add Opus 4.5/4.6, Sonnet 4.6, Haiku 4.5 mappings
Map the new aliases + date-suffixed variants to the kiro-cli model IDs that CodeWhisperer already accepts (e.g.
claude-opus-4.6).TestModelMap_MappingsAreCorrectFormatrelaxed to accept three value formats:CLAUDE_XXX_V1_0,claude-xxx-N.M, andauto. Added dedicated tests for the new aliases.feat(server): add BIND_HOST and DISABLE_AUTH for gateway deployments
