Research direction

Start with pkg/cli/data/models.json and actions/setup/js/models.json, which the issue says are identical; compare their model records and pricing with the reported Copilot SDK values. Run make refresh-models-json as suggested, then adjust the files to add claude-haiku-5.5 and correct the listed cache_read discrepancies. Done when both files agree and the reported prices match.

Description

automation models
Summary

4 pricing items + 1 stale alias found; no new model families lacking alias coverage.

  • Providers queried: OpenAI (135), Anthropic (12), Gemini (50), Copilot SDK (24), Copilot reflect (42 IDs, incl. deprecated/embedding IDs)
  • Proposed alias changes: 1 (optional cleanup)
  • Pricing gaps found: 5
  • Docs pricing table (Step 2.5): skipped — Playwright extraction was not performed; the billing artifact is an empty placeholder. SDK vs reflect used for validation.
Provider Model Counts
Provider Models Status
openai 135 ✅ ok
anthropic 12 ✅ ok
gemini 50 ✅ ok
copilot-sdk 24 ✅ ok
copilot (reflect) 42 ✅ ok
Raw API Fields Discovered
  • Copilot SDK: billing.tokenPrices (inputPrice, outputPrice, cacheReadPrice, cacheWritePrice, contextMax, longContext tier), discountPercent (auto only).
  • Reflect: model ID list only (no billing multiplier in this run).
  • Gemini: input/output token limits; Anthropic: display_name; OpenAI: owned_by.
models.json Pricing Analysis

(pkg/cli/data/models.json and actions/setup/js/models.json are identical.)

Missing from models.json
Model ID Provider Inferred Pricing (per 1M tokens) Basis
claude-haiku-5.5 copilot / anthropic (claude-haiku-5-5) in $10 (SDK units: 10, out 50, cache read 1, cache write 12.5) → stored form: input 1e-07, output 5e-07, cache_read 1e-08, cache_write 1.25e-07 Copilot SDK billing.tokenPrices

Note: models.json stores per-token costs; SDK prices are in units of 1e-8 $/token (e.g. 200 → 2e-06). provider_type would be anthropic.

Historical entries not currently returned

Kept as historical: claude-fable-5, claude-fable-5.1, claude-opus-4.5/4.6/4.7, claude-sonnet-4/4.5/4.6, gemini-2.5-pro, gemini-3-flash-preview, gemini-3.1-pro-preview, gemini-3.5/3.6/3.7/3.8-flash (not in Copilot SDK; present in Gemini API), gpt-5.2, gpt-5.2-codex, kimi-k2.7-code, kimi-k3, mai-code-1-flash-picker, raptor-mini.

Inferred vs stored pricing discrepancies
Model ID Stored SDK Field
claude-sonnet-5.5 cache_read 2e-07 1e-07 cache_read
gpt-5.4-mini cache_read 7e-08 7.5e-08 cache_read (rounding)
gpt-5.3-codex cache_read 1.7e-07 1.75e-07 cache_read (rounding)
gpt-5-mini cache_read 2e-08 2.5e-08 cache_read (rounding)

All other input/output/cache prices of the 23 SDK-priced models match.

Proposed Alias Updates
  1. What: Optional cleanup of reasoning alias. Why: no live Copilot model matches copilot/o1*|o3*|o4*; OpenAI API still lists o1/o3/o4-mini, so no change is required — keep as is.
  2. All live models are covered by existing aliases (haiku covers claude-haiku-5.5; sonnet-6x covers sonnet-5.5; gpt-6 covers gpt-6.1-sol/astra/luna/sol; gemini-flash-lite covers gemini-3.8-flash-lite-*; grok covers 4.5–4.7; mai-code covers mai-code-1.1-flash).
  3. Task-oriented aliases (coding, reasoning, vision, summarization) already exist.
Full Copilot Model IDs (reflect)

claude-haiku-4.5, claude-haiku-5.5, claude-opus-4.8, claude-opus-5, claude-opus-5.5, claude-sonnet-5, claude-sonnet-5.5, gpt-5-mini, gpt-5.3-codex, gpt-5.4, gpt-5.4-mini, gpt-5.5, gpt-5.6-luna, gpt-5.6-luna-utility, gpt-5.6-sol, gpt-5.6-terra, gpt-6-astra, gpt-6-luna, gpt-6-sol, gpt-6.1-sol, grok-4.5, grok-4.6, grok-4.7, mai-code-1.1-flash, trajectory-compaction, text-embedding-*, plus deprecated gpt-3.5/4/4o/4.1 variants (ignored).

Notes
  • Suggested action: add claude-haiku-5.5 to github-copilot in both models.json files and fix the cache_read values above (run make refresh-models-json, then adjust).
  • Deprecated IDs (gpt-4o-mini, gpt-4.1, gpt-4o, gpt-5.4-nano) were ignored per policy.
  • gpt-5.6-luna-utility and trajectory-compaction appear in reflect only (not in SDK); no pricing available.
