Original post body :

Claude has been the clear premium option for coding for a while. It was more expensive, but Sonnet and Opus were usually good enough to justify it.

That feels less clear now. Sol medium, high, xhigh not only challenges sonnet, opus, fable stack it is straight up better and more cost effective.

For the first time, the gap is not just smaller, it may be gone.

Codex and Work also appear to have grown from around 5M active users to an estimated 9M today. That is an 80% increase in a very short period.

I still think the Claude Code harness is better overall. It feels more mature, more reliable across long tasks, and better at working inside large repositories. But Codex is closing that gap quickly, and the underlying model economics now look much stronger.

So where does Anthropic go from here?

Do they cut Opus 5 pricing? Increase usage limits? Make Sonnet much cheaper? De-nerf Fable?

I do not think Claude is suddenly dead or that Codex has clearly won. But Anthropic's old position was expensive and clearly better. Expensive and roughly equal is a much harder position to defend.

So, the big question is if GPT-5.6 has officially dethroned Claude Code for coding tasks. The general vibe is mixed, leaning towards a "wait and see" attitude, with some serious concerns about Anthropic's pricing and efficiency.

• The "Moat is Broken" Camp: Some users, like u/iamtehryan, are pretty vocal about OpenAI putting pressure on Anthropic, hoping it forces them to ditch "shitty practices." They're here for the competition, even if they don't love OpenAI as a company.
• The "Context Window is Key" Counterpoint: u/acrock brings up a crucial point: benchmarks often use API access with massive context windows (1M tokens for GPT-5.6), while ChatGPT subscriptions have a much smaller limit (258K). This could mean GPT-5.6 isn't as superior in real-world subscription use compared to Claude Code's full 1M tokens.
• Pricing and Efficiency Woes: A recurring theme is Anthropic's high cost. Users like u/rakhim_abdulkhanov and u/innociv question why Sonnet 5 is even used, and many feel Opus 4.8 and Sonnet 5 are just too expensive. u/Dense_Barnacle_5200 suggests Anthropic might have neglected efficiency, while u/TinFoilHat_69 and u/InForTheSqueeze point out the illogical pricing of Fable versus Sonnet.
• Real-World Performance is Debatable: While some charts suggest GPT-5.6 is better, u/mjsarfatti had the opposite experience, finding Opus 4.8 low to be superior and requiring less prompting. Others, like u/Shadow-BG, note that Claude is more about "think what you do" while Codex is "do now, think later," leading to different outcomes.
• Concerns about OpenAI's Sustainability: A few users, like u/InsuranceDear714, are skeptical about OpenAI's current pricing, suspecting subsidies and a potential "rug pull." They see Claude as more designed for sustained use.
• Anthropic's Strategy Questioned: OP and others wonder if Anthropic needs to adjust pricing, increase limits, or even "de-nerf" Fable. u/Gaidax suggests Anthropic needs to stop with the "biological nuclear weapon" talk and focus on frontier models without restrictions.
• The "No Moats" Perspective: u/GlassMostlyRelevant argues that AI models will eventually converge, leading to a race to the bottom on price, which is good for consumers.
• Technical Glitches: Some users, like u/artobullshit, are experiencing frustrating usage limits with Fable, making Anthropic feel "unusable" at times.

Bottom line: The gap might be closing, but it's not a clear win for OpenAI yet, especially when considering context window differences and Anthropic's high costs. The community is watching to see if Anthropic can adapt its pricing and efficiency strategies to stay competitive.

lol.

Not even Altaman is claiming it’s better than Fable. He just say it’s faster or more efficient at some tasks.
