GPT / ChatGPT

In the repliesActive_Variation_194 preferred Opus 5.5 for coding, describing less reliance on defensive coding and fallbacks; Crinkez also reported a positive Opus 5.5 usage experience. FraffoD said GPT-6 Sol at High worked well for them with Astra planning and Sol execution, with little usage during a day of work. Just_Lingonberry_352 said Sol still over-engineers but follows instructions better, and reported preferring xhigh with little usage decline. These are individual reports without matched tasks or usage logs.

Discussion focuses on GPT-6 Sol within the r/OpenaiCodex community. Specific configuration details like High and xhigh effort levels or Astra pairings apply only to individual commenters as reported.

Single informal r/OpenaiCodex thread reviewed September 25, 2026. Task details, account tiers, comparable runs and system logs were not supplied; reports are not a benchmark.

In the repliesExtra_Loquat_7667 reported a Pi-Agent tool-call mistake: after a request for a 30-second bash timeout, Luna repeatedly passed 30,000 seconds until corrected. No reproducible transcript was supplied. Maglcite later clarified that their preference for Luna concerned orchestration and subagent control, rather than direct implementation. On September 30, Constant_Art_20 reported positive first impressions using GPT-6 Sol to plan and review projects in the chat interface, noting it seemed to make fewer assumptions than GPT-5.6 Sol and double-checked work, though they had not tested it for implementation. Maglcite replied that implementation was fine and that their switch was about planning and controlling subagents.

OpenAI positions Luna as the lower-cost model in the GPT-6 tier, with a gradual rollout planned across ChatGPT Work and Codex. The experiences described rely on third-party agent harnesses rather than standard Codex environments.

Individual r/codex reports reviewed September 30, 2026. These remain personal impressions; the experiences do not establish general reliability, benchmark results, or account allowance rates.

In the repliesBellacosePlayer said one Sol High plan looked good and used 1% of their five-hour allowance, explicitly calling it a sample of one. Life_is_important reported that a one-file HTML phone game used 3% of their hourly allowance, with no visible change to their weekly meter. ktsmediaprod88 said a Sol xhigh run returned links and documentation paths without clarifying completed repository work. In a multi-agent setup, ohrajaaa estimated that a Sol Medium coordinator with a Luna coding worker yielded three to four times as much usable work as their previous Pro setup; no usage export was shared. Other commenters disagreed about Sol’s speed and quality.

OpenAI announced GPT-6 Sol and Luna on September 22, 2026, rolling out to Codex and ChatGPT Work but not standard Chat. OpenAI listed Sol API pricing at $2 input and $10 output per million tokens, half of GPT-5.6 Sol promotional pricing. That API reduction does not verify subscription quota increases.

Individual r/codex reports reviewed September 23, 2026. The thread includes no comparable task logs or account telemetry; API prices do not establish subscription allowances.

In the replieslinmao liked the Sol render and preferred it to their recollection of GPT-5.6 Sol, without supplying a matched older result. shumeng said their Luna pelican looked worse and lacked motion, while finding an Astra result acceptable. These are individual visual judgments from different, uncontrolled runs.

LINUX DO topic 2938313, reviewed September 23, 2026. Two rendered images are linked, but exact prompts, generation settings and raw SVG code were not visible.

In the repliesIn visible replies, ActionOrganic4617 claimed Astra completed nine mandatory corporate-training modules in parallel with a 100% score after opening the portal in the Codex browser, muting audio and accelerating playback where possible. Other commenters discussed local models, quotas and HR automation without providing controlled validation. These are individual experiences, not verified platform limits or performance standards.

In the repliesResponding to KazamiMichiru, the author described judging copy from the target customer's perspective and using an AI rubric to check guidelines, jargon, and fabrication. Replying to imLahm21, the author specified medium reasoning effort.

Personal impressions and model-generated scores, not an independent benchmark. Exact prompts and a live conversion test were not supplied.

In the repliesCommenter david_vabi reported a positive weekend impression using GLM 5.3 Flash, differing from the author's distrust of that variant. The author clarified that GLM 5.3 was acceptable for auxiliary work but not important tasks.

Personal reports, not reproducible tests. The reverse-engineering example was not explicitly tied to the emulator project. A commenter’s hosting offer is omitted.

In the repliesCommenter Jonathan_Rivera outlined a setup using Codex models dividing roles across models: Luna max for daily work, Astra as critic, Terra as tester, and Sol as orchestrator. The visible exchange provides no comparative token or cost measurements showing that this split reduces consumption.

Five specialized Terra agents with high reasoning in Hermes · Exact model version identifiers and token counts unspecified.

Self-reported configurations, not verified billing or a benchmark. A later reply promotes the commenter’s own tool router; that recommendation is omitted.

In the repliesA reader weighing Claude Max asks whether to subscribe. The author says a long coding day can exhaust their weekly quota; another commenter asks for GLM and Gemini to be included. The estimates are the author’s calculation, not a verified value ranking.

In the repliesResponding users reported mixed functional tradeoffs across early tests. Commenter kbrannigan observed faster information synthesis and natural phrasing compared to competing models, but noted reaching a five-hour usage cap after sending fifteen messages. Meanwhile, kingkongjaffa tested matching learning prompts against GPT-5.6 Sol, reporting that Astra returned three to five times as many web sources alongside higher-quality reference materials.
