No linked issue: this PR was requested directly (via Discord) in response to OpenAI's GPT-6 Sol/Luna release announcement: https://openai.com/index/introducing-gpt-6-sol-and-luna/

Description

Adds gpt-6-sol and gpt-6-luna to the OpenAI model catalogs, mirroring how the GPT-5.6 family (sol/terra/luna) was added in #876:

packages/types/src/providers/openai.ts — both models in openAiNativeModels with verified pricing from OpenAI's model docs (gpt-6-sol, gpt-6-luna):
- gpt-6-sol: $2 input / $10 output per MTok, cache writes $2.50 (1.25× input), cached reads $0.20 (90% off), flex tier at 50%, priority tier at 2×, >272K long-context pricing (2× input/cache, 1.5× output)
- gpt-6-luna: $0.10 input / $0.50 output per MTok, cache writes $0.125, cached reads $0.01, same tier and long-context structure
- Both: 1.05M context, 128K max output, reasoning efforts none/low/medium/high/xhigh/max (default medium), image input, verbosity, prompt caching
packages/types/src/providers/openai-codex.ts — both models in the Codex (ChatGPT subscription) catalog with subscription pricing ($0), using the 372K context window of their GPT-5.6 predecessors (the Codex backend model metadata is not publicly verifiable; announced availability covers Plus, Pro, Business, Enterprise, and Edu)
packages/types/src/__tests__/openai-models.test.ts — catalog assertions for both models

Reviewer notes / deliberate scope decisions:

Default model IDs are unchanged (gpt-5.6-sol).
No fetcher special-cases added for OpenRouter / Vercel AI Gateway / NanoGPT / LiteLLM: those exist only for gpt-6-astra's required-reasoning curation, and gateway availability of the new models is not yet verified — gateways will pick them up dynamically like the GPT-5.6 family.
opencode-go untouched: it curates only gpt-5.6-luna because the Go gateway catalogue lacks metadata; Go gateway support for the GPT-6 models is unverified.
The new models are not added to the Codex RESPONSES_LITE_MODEL_IDS set (an internal wire-format requirement that can't be verified without Codex backend access).

Test Procedure

pnpm test from the repo root: all 13 turbo tasks pass (including packages/types 435 tests and webview 1866 tests).
Targeted: packages/types vitest for openai-models.test.ts (3/3), src vitest for openai-codex / openai-native / openai-native-usage specs (158/158).
eslint --max-warnings=0 on the three touched files: clean; tsc --noEmit in packages/types: clean.

Additional Notes

Pricing and capability values were taken from OpenAI's announcement and the official per-model API docs pages (cached input at 10% of input rate, cache writes at 1.25× input, Flex/Batch at 50% of standard rates, Fast/priority at 2×, and >272K long-context multipliers).

Add gpt-6-sol and gpt-6-luna to the OpenAI native and OpenAI Codex (ChatGPT subscription) model catalogs, announced by OpenAI on September 22, 2026: - gpt-6-sol: $2 input / $10 output per MTok, 1.05M context, 128K max output, cache writes 1.25x input, cached reads 90% off, flex 50% / priority 2x tiers, >272K long-context pricing - gpt-6-luna: $0.10 input / $0.50 output per MTok with the same context, caching, tier, and long-context structure Both support reasoning effort levels none through max (default medium), image input, and verbosity, mirroring the GPT-5.6 family entries. Codex catalog entries use subscription pricing with the 372K context window of their GPT-5.6 predecessors.

These are the only new catalog entries in this PR without test coverage — nothing in the test suite imports openAiCodexModels, so a typo in contextWindow or the tool filters would ship silently. Would it make sense to lock these alongside the native entries in openai-models.test.ts?

The toMatchObject assertions here leave includedTools/excludedTools, supportsVerbosity, and Luna's longContextPricing unpinned (Sol's is checked), so mutations to those fields would pass CI. Would switching both to full-entry toEqual — as the tiers asserts already do — close that in one move?

Added full tests for both Codex model entries.
