Research direction

This is a generated inventory report, not a task. The alias proposals touch pkg/cli/data/models.json and actions/setup/js/models.json, which must stay identical, and the Copilot SDK pricing fields are the reference. Before changing anything, confirm with a maintainer whether the gemini-4 alias and the optional trajectory-compaction entry should be added. Done means the agreed alias entries are in both files and match the stored pricing.

Description

Summary

Minor gaps found. Alias coverage is largely current; a few Copilot-only utility models and one new Gemini family are not covered.

  • Providers queried: OpenAI (135), Anthropic (12), Gemini (50), Copilot SDK (24), Copilot reflect (42 IDs)
  • Proposed alias changes: 2
  • Pricing gaps found: 2 (Copilot, no pricing data available)
  • Copilot docs pricing table: skipped — playwright-cli browser_navigate is not a valid command in this environment (Unknown command), so the artifact stayed empty.

Raw API Fields Discovered
  • Copilot SDK: billing.tokenPrices (input/output/cache/longContext), capabilities (vision, tool_calls, reasoning_effort), policy, provider_type.
  • Copilot reflect: model_metadata[].pricing.default/long_context, wire_api, api_version.
  • Gemini: input/output token limits, supported generation methods. Anthropic: display_name. OpenAI: owned_by, created.
models.json Pricing Analysis
Missing from models.json
Model ID Provider Inferred Pricing Basis
gpt-5.6-luna-utility copilot unknown reflect lists it with no pricing; absent from SDK
trajectory-compaction copilot unknown reflect lists it (wire_api: completions), no pricing

Both look like internal utility models, not user-selectable; adding them is optional.

Historical entries not currently returned

Older entries (e.g. claude-sonnet-4, gpt-5.2, gemini-2.5-pro, kimi-*, raptor-mini, claude-fable-*) are not in the Copilot SDK list. Retained as historical.

Inferred vs stored pricing discrepancies

None. All 23 Copilot SDK models with tokenPrices match the stored github-copilot/* input/output costs in pkg/cli/data/models.json (identical to actions/setup/js/models.json).

Proposed Alias Updates
  1. gemini-4 (new family): live Gemini model gemini-4-argon is not matched by any alias.
{ "gemini-4": ["copilot/gemini-4*", "google/gemini-4*", "gemini/gemini-4*"] }
  1. utility/gpt-5.6: gpt-5.6-luna-utility already matches gpt-5.6*; no change needed. For trajectory-compaction, optionally add:
{ "trajectory-compaction": ["copilot/trajectory-compaction*"] }

Already covered: all Claude 4.x/5.x, GPT-5.x/6.x, Grok 4.5–4.7, MAI-Code, Gemini 3.x flash/pro, gemma, lyria, veo, deep-research, antigravity, nano-banana, computer-use, robotics.
