feat(models): update the capable-tier Sonnet to Claude Sonnet 5#1198
Merged
Conversation
Swaps the default "capable" model from claude-sonnet-4-6 to the newly released claude-sonnet-5 (GA 2026-06-09) across the registry, adaptive routing, providers, telemetry, token estimation, and the literal model_id defaults scattered through the codebase. Verified the ID against the live Anthropic models doc before changing anything. Pricing is unchanged: $3/$15 per MTok standard (introductory $2/$10 through 2026-08-31). 1M context, 128K max output, adaptive thinking, effort defaults to high. Sonnet 4.6 is now a legacy model. - Full claude-sonnet-4-6 -> claude-sonnet-5 swap across src/ + tests/ (65 files); matching test expectations updated so CI stays green. - Registry CAPABLE ModelInfo + TIER_PRICING comment refreshed. - Stale "Sonnet 4.6" prose comments updated to "Sonnet 5". - Left claude-sonnet-4-5 (legacy 4.5) references untouched. - CHANGELOG Unreleased "Changed" entry added. 962 model/routing/pricing/telemetry/provider tests pass. The only failures are the live-API integration tests in tests/models/test_sonnet_opus_fallback.py (skipif HAS_API_KEY) — a local creditless-key 400, skipped in CI; the new ID is accepted (no 404), confirming the swap.

Follow-up to the src/tests Sonnet 5 swap (#1198): updates the claude-sonnet-4-6 references in served docs, the example config, and the blog tutorials to claude-sonnet-5, so user-facing surfaces match the registry default. - docs/ served pages (installation model list, agent-factory capable table, API_REFERENCE + agent-factory-readme code examples) - examples/config/attune.config.example.yml - website/content/blog/*.mdx code snippets Left untouched (historical / generated, not the cleanup target): .claude/lessons.md (illustrative stable-alias example), .claude/plans/* (dated planning docs), docs/archive/**, weekly-reports/**, the CHANGELOG entry that introduced 4.6, and website/public/framework-docs/** (built mkdocs HTML — regenerated from docs/ at build time).

What
Updates attune's default "capable" model from
claude-sonnet-4-6to the newly releasedclaude-sonnet-5(Claude Sonnet 5, GA 2026-06-09).I verified the model ID against the live Anthropic models doc before touching anything — my cached reference predated the release, so this confirms
claude-sonnet-5is real and current (Sonnet 4.6 is now legacy).Scope — full swap (src/ + tests/)
A clean ID swap
claude-sonnet-4-6 → claude-sonnet-5across 65 source/test files (169 occurrences), plus the CHANGELOG. Pricing is unchanged ($3/$15 per MTok standard), so no pricing math moved.ModelInfo+TIER_PRICINGcomment"capable"map, executor, token estimator, telemetry baselinesmodel_id="claude-sonnet-4-6"defaults across providers, configs, workflows, agent factory, orchestration tools# Sonnet 4.6prose comments refreshed to# Sonnet 5claude-sonnet-4-5(legacy 4.5 — a different model) and the historical CHANGELOG entry that introduced 4.6Sonnet 5 facts (from the live doc)

CI runs these withANTHROPIC_API_KEY=""so they're skipped. The new ID was accepted by the API (billing 400, not a 404 model-not-found), which itself confirms the ID is valid.Not in this PR (follow-up if wanted)
claude-sonnet-4-6also appears in docs/ (6), website/ (7), examples/ (1), and.claude/(3) — out of the chosen src+tests scope. Happy to sweep those in a follow-up (website has its own deploy + content-accuracy guard).🤖 Generated with Claude Code
