The much anticipated launch of the Mythos-class model was marred by some controversial usage policies
By some measures, Opus 4.8, barely two weeks old, was already the leading model in the world. But now, 34 days after the SpaceXai deal and 63 days after the original Mythos announcement*, we have a Mythos-class model (at least 2x size of Opus) available to everyone (in coinciding with Claude Tokyo). It is a feat of incredible engineering (and commitment to access) to make these research models GA, and the benchmarks are great… with asterisks. Here they are on yesterday’s brand new, out of distribution, FrontierCode Diamond, going from 13.4% to 29.3%:
The blog and the system card contain most of the authoritative information, but don’t miss the youtube videos showing it playing Factorio, Pokemon (unlike Claude Plays Pokemon, this is just using vision, no complex harness as we covered in our pod), EDM visualization (never having head music before), 3D CAD editor creation and printing and more from their main intro video.
API pricing is also fantastic, at roughly 2x Opus.
The asterisks come because Fable is released with two controversial changes:
: “We will rNo ZDRequire 30-day retention for all traffic on Mythos-class models, on both first- and third-party surfaces. We won’t use this data to train new Claude models, or for any non-safety-related purpose, and we’ve instituted new privacy protections including logging all human access to the data and ensuring its deletion after 30 days in almost all cases ...” (seefull policy)RSI suppression: “In light of theability of recent models to accelerate their own development, we’ve implemented new interventions that limit Claude’s effectiveness for requests targeting frontier LLM development (for example, on building pretraining pipelines, distributed training infrastructure, or ML accelerator design). Using Claude to develop competing models already violates our Terms of Service, but enforcing this restriction through our safeguards avoids accelerating the actors most willing to violate these terms.> Unlike our interventions for cybersecurity, biology and chemistry, and distillation attempts,
these safeguards will not be visible to the user. Fable 5 will not fall back to a different model. Instead, the safeguards will limit effectiveness through methods such as prompt modification, steering vectors, or parameter-efficient fine-tuning (PEFT). These interventions will not affect the vast majority of coding work.We estimate they will impact ~0.03% of traffic, concentrated in fewer than 0.1% of organizations”.
The vast majority of users will not be affected by these limitations, but the open AI community is understandably upset, as you will see below.
You can find more of their recommendations on usage in Diane Penn’s Tokyo talk, which we have clipped below.

Top Story: Anthropic Claude Fable 5 and Mythos 5 release
What happened
Anthropic released two versions of its next major model family: Claude Fable 5 for general availability and Claude Mythos 5 for restricted access.
Anthropic officially announced
Claude Fable 5 as its “first generally available Mythos-class model,” saying it exceeds any model it has previously made broadly available and isstate-of-the-art on nearly all tested benchmarks@claudeai,@claudeaiAnthropic said
Fable 5 is the same underlying model as Mythos 5 with added safeguards, and that some cyber/bio/chemistry/distillation-related prompts may be** routed to Claude Opus 4.8**instead@ClaudeDevs,@scaling01Anthropic stated that for a “narrow range” of potentially harmful topics,
queries transparently fall back to Opus 4.8, and claimed** 95%+ of sessions never see one**according to early user-facing messaging@claudeai,@mikeykAnthropic developer messaging said fallback is available server-side and via SDK middleware in
Python, TypeScript, Go, Java, and C#@ClaudeDevsPricing for
both Fable 5 and Mythos 5 was reported as**$10 / million input tokens and $50 / million output tokens**; cache pricing was later reported by third-party evaluators as**$12.50 / million cache writes and $1 / million cache reads**@scaling01,@ArtificialAnlysFable 5 kept Anthropic’s
1M-token context window according to Artificial Analysis@ArtificialAnlysAnthropic put Fable 5 into
Pro, Max, Team, and seat-based Enterprise plans until June 22, then said it would require** usage credits**due to capacity constraints, with plans to restore broader subscription access later@ClaudeDevs,@scaling01,@ArtificialAnlys,@kimmonismusConfusion over the temporary inclusion was immediate; users asked what “included until June 22” meant and Anthropic staff clarified the rollout
@dejavucoder,@TheAmolAvasareAnthropic later reset 5-hour and weekly rate limits across products after heavy demand@ClaudeDevs
Official claims and third-party benchmark data
Anthropic and partner platforms reported a broad benchmark lead, especially in coding and long-horizon agentic tasks.
Anthropic’s public claim: Fable 5 is especially strong in
software engineering, knowledge work, scientific research, and vision, and** its lead increases with task length and complexity**@claudeaiCursor said Fable 5 set a new
CursorBench SOTA at 72.9%,** 8 points above the previous best**@cursor_aiCognition said Fable 5 took the
#1 spot on FrontierCode, and Devin integrated it into Devin Cloud Ultra, Desktop, and CLI@cognition,@cognitionCline reported Fable 5 at
88.0% on Terminal-Bench 2.1, beating GPT-5.5 by** 4.6 points**@clineArtificial Analysis placed Fable 5
#1 on its Intelligence Index at 64.9, roughly** 5 points ahead of GPT-5.5**, and said Anthropic occupied the top two spots@ArtificialAnlysArtificial Analysis also reported:
GDPval-AA Elo 1932, #1 on agentic real-world knowledge work@ArtificialAnlys** 53% on Humanity’s Last Exam**, more than** 7 points aheadof the next-best model, while fallback triggered on 9% of HLE tasks**@ArtificialAnlys~8% fallback routing across Intelligence Index tasks, mostly on scientific questions@ArtificialAnlysAnthropic stated fallback occurs in
fewer than 5% of sessions on average@ArtificialAnlys
Community benchmark summaries highlighted very large deltas in coding:
SWE-Bench Pro: Fable 5 80.3% vs GPT-5.5 58.6%@Yuchenj_UW** FrontierCode Diamond: Mythos 5 30.9% vs second-best 13.4%@scaling01 Anthropic ECI 161.29 for Mythos 5**@scaling01
Artificial Analysis noted that Fable 5’s knowledge benchmark jump on
AA-Omniscience could imply alarger model than prior public Anthropic models, though that is inference rather than confirmed spec@ArtificialAnlys
Product behavior, usage profile, and deployment details
The release was defined as much by workflow changes and cost profile as by raw evals.
Anthropic staff and early users repeatedly described Fable 5 as a model for
very long, high-effort tasks, with users shifting from giving it tasks to giving it** objectives/responsibilities**@felixrieseberg,@ClaudeDevs,@alexalbert__Anthropic advised users to default to
xhigh/high effort, rewrite old CLAUDE.md instructions, and let the model use more judgment@alexalbert__Anthropic’s developer messaging emphasized
multi-agent orchestration, with Fable delegating to smaller models in Claude Managed Agents@ClaudeDevsMultiple testers described Fable as
slow, token-hungry, expensive, but unusually capable:Dan Shipper said it routinely used
500k to 1M tokens on tasks and was best reserved for heavy jobs@danshipperSimon Willison called it “slow, expensive and capable”
@simonwTheo quickly hit limits and later welcomed Anthropic’s rate-limit reset
@theo,@ClaudeDevs Third-party and internal anecdotes emphasized large gains on long-running engineering tasks:
Ethan Mollick said he could hand it a
15-page design document and it would work for9+ hours@emollickKimmonismus highlighted Anthropic’s claim that Stripe used Fable to do a
50-million-line Ruby migration in a day, replacing what would have taken** a whole team over two months**@kimmonismusVictor Taelin reported Fable finding a subtle bug and producing claimed speedups up to
1770% in one case, though he still needed to audit correctness@VictorTaelinAnthropic-associated posts cited
430x kernel speedups,** 69x self-training speedups**, and** 10x drug-design acceleration**, though these came from benchmark/system-card interpretations and should be treated as vendor-side claims unless independently replicated@scaling01,@scaling01,@scaling01
Ecosystem rollout was immediate: Fable 5 appeared in
Cursor, Devin, Notion, Microsoft Foundry, GitHub Copilot App/CLI, Cline, Replit, Base44, MagicPath, Arena, MCP Atlas and more@cursor_ai,@cognition,@NotionHQ,@Azure,@pierceboggan,@cline,@pirroh,@ScaleAILabs
Safety architecture and the main controversy
The biggest debate was not whether Fable/Mythos is strong; it was Anthropic’s decision to silently reduce usefulness on some frontier-AI-development tasks.
Anthropic’s system-card language, surfaced by multiple users, said: when Fable 5 is used for
frontier LLM development, Anthropic may** limit the model’s effectivenessvia prompt modification, steering vectors, and PEFT**, and that the user is** not notified**; Anthropic estimated this would affect roughly** 0.03% of traffic**@Hangsiin,@kimmonismusAnthropic also separately disclosed auto-rerouting for
cybersecurity and biosecurity requests to Opus 4.8@ClaudeDevsThis distinction mattered:
some risky queries are visibly rerouted/billed as Opus, while** frontier-LLM-development requests may be silently weakened rather than rerouted or refused**Critics argued that this creates an
unlogged confounder in research and engineering workflows:“silent handicaps should not be a thing in a paid product”
@nrehiew_“degrading performance on ML research without telling the user is shockingly hostile”
@deanwball Several researchers framed it as
anti-competitive ladder-pulling against open research and open weights:“labs starting to pull up the ladders”
@natolambert“this is the biggest wake-up call to protect and nourish open source AI”
@rasdani_“They didn’t mean AI research, they meant
yourAI research”@bayeslord“original thinkers can’t be an underclass”
@marksaroufim“concentration of power, capabilities and economic wealth is the biggest risk in AI”
@ClementDelangue Multiple users worried the classifier boundary was too broad or too error-prone:
one user said “the word cancer is flagged as a biosecurity risk”
@DeryaTR_another said Fable wouldn’t answer “What does the heart do?”
@Yuchenj_UWusers in biology reported account-context differences, including being able to use Fable in
Incognito Mode but not normal mode@cremieuxrecueilTeknium and others reported refusal on simple engineering prompts
@Teknium,@Tekniumusers reported PTX ISA questions and inference optimization queries getting flagged
@snowclipsed,@dejavucoder Some examples were humorous but pointed: users joked that asking for inference code caused the model to “start importing ONNX” or implementing JEPA, as a sign of capability steering
@vikhyatk,@MattVMacfarlane Facts vs. opinions

@ClaudeDevsAnthropic disclosed silent interventions for frontier LLM development affecting about0.03% of traffic@HangsiinFable is temporarily included in subscriptions until
June 22, then credit-based@ArtificialAnlys Opinions / interpretations
“Anthropic won,” “Anthropic has a coding moat,” “Anthropic going for ASI” are commentary rather than verified fact
@scaling01,@scaling01,@scaling01Claims that the move is primarily for
IPO optics,** anti-open-source positioning**, or specifically to slow** Meta/China/open labs**are plausible interpretations but not confirmed by Anthropic@kimmonismus,@kylebrussell,@natolambertClaims that Anthropic is acting from sincere safety beliefs rather than cynical moat-building are also interpretive
@finbarrtimbersSubjective reports like “GPT-4 moment,” “big model smell,” “strictly dominates me as an engineer,” or “doesn’t seem much better to normal users” are experiential, not standardized evidence
@karinanguyen,@bcherny,@akbirkhan,@citrini
Different perspectives
Supportive / capability-first
Anthropic staff and close testers described Fable 5 as a
step-function improvement:Felix Rieseberg: shift from giving AI tasks to giving it responsibilities
@felixriesebergAlex Albert: model feels collaborative rather than tool-like @alexalbert__Karpathy: a “major-version-bump-deserving step change,” especially on long difficult tasks, though safeguards are “a little too trigger happy for launch”
@karpathyBcherny: biggest step since Opus 4.5; the model shows judgment, taste, methodical debugging
@bcherny Third-party infra and app vendors emphasized benchmark wins and integration value rather than the safety controversy
@cursor_ai,@cognition,@NotionHQ,@Azure
Critical / trust and openness
Many researchers and open-model advocates argued the silent throttling is unacceptable even if safety-motivated:
Natolambert called doing it without telling users “misaligned”
@natolambertDean Ball warned it could attract
antitrust scrutiny@deanwballJeremy Howard called it “a very dark and very sad day”
@jeremyphowardGneubig warned of a future where AI is provided only to a privileged few
@gneubigEric Zelikman framed it as silently sabotaging customers
@ericzelikman Open-source supporters used the launch as an argument for
sovereign/open models@nickfrosst,@NoahZiems,@ClementDelangue
Neutral / mixed
Some observers argued Anthropic probably
sincerely believes these interventions are necessary for safety, even if the product design is poor@finbarrtimbersOthers said Anthropic does
not owe anyone unrestricted frontier capability, but still saw this as straightforward business and market segmentation rather than altruism@suchenzangKarpathy’s view is mixed: model quality is exceptional, but launch safeguards are over-sensitive and should likely be tuned
@karpathy Research restrictions, privacy, and enterprise implications
The discussion expanded from safety to broader questions of trust, privacy, and enterprise reliability.
The central enterprise issue was
predictability: if a provider can silently degrade outputs based on inferred task category, users may no longer know whether failures come from the model, the prompt, or hidden intervention@MattGibsonMusic,@code_starSome users worried this is effectively a
supply-chain risk for important workflows, pushing companies toward open weights or in-house models@NoahZiems,@delipraoThere was also concern that account-level context or prior usage history might affect trigger behavior, as seen in biologists’ reports about normal vs incognito mode
@cremieuxrecueilNo tweet in the supplied set provided direct evidence that Anthropic was
training on user data or violating stated data privacy terms; the privacy debate here was mostly aboutbehavioral profiling / silent policy enforcement rather than classic training-data privacyFor research users, the hidden intervention was framed as especially damaging because it undermines
reproducibility and scientific attribution@deanwball,@MattGibsonMusicFor enterprise buyers, the issue is not just whether the model is powerful, but whether it is a
stable and auditable dependency for coding, medicine, science, finance, and infrastructure
Context
This launch matters because it combines a visible capability jump with a visible shift in access control.
The release landed amid intense competition with GPT-5.5, upcoming GPT-5.6, and Gemini 3.5 Pro; several posters argued Anthropic has opened a temporary lead in coding/agentic work
@kimmonismus,@teortaxesTexIt also lands in a broader argument about the open vs closed model gap; one linked Epoch-style framing said open-weight models lag closed frontier models by about** 4 months on average**@dl_weeklyCommunity reaction suggests the launch may be remembered not only for “big model smell” and benchmark jumps, but for normalizing
selective capability release: public access to the frontier model, but with** domain-specific hidden limits**That policy line is likely to influence future debates around:
safety vs opennessfair access to frontier research toolsantitrust and platform powerenterprise trust in API providerswhether open models become the default for sensitive technical work even when they trail on raw capability

agent tasks, and persistent low-latency kernels to reduce launch/sync overhead. A key unresolved technical caveat from comments is that Xiaomi does not specifywhich8 GPUs were used, making reproducibility and cost/performance comparisons ambiguous. Commenters debated the economics of “Token Winter,” arguing the bottleneck is less model demand than overpriced/hoarded Western GPU supply, while Chinese compressed sparse architecture/MoE work fromDeepSeek, Xiaomi, and MiniMax is becoming more inference-efficient. Others highlighted Xiaomi’s selective FP4 strategy as the most important detail because naïve full-model FP4 degrades reasoning, code, and logic.A key technical detail highlighted is that Xiaomi did
selective FP4 quantization rather than applying FP4 uniformly: only theMoE Experts inMiMo-V2.5-Pro are quantized to FP4, while non-expert modules retain original precision to avoid degradation in reasoning, logic, and code generation. The comment notes Xiaomi usedFP4 QAT to reduce model size and improve bandwidth utilization while keeping capability near the original model.The released model weights are available on Hugging Face as
XiaomiMiMo/MiMo-V2.5-Pro-FP4-DFlash:https://huggingface.co/XiaomiMiMo/MiMo-V2.5-Pro-FP4-DFlash. This is relevant because it allows independent inspection or benchmarking of the claimed1,000+ tps
throughput on an 8-GPU server.Several commenters questioned the hardware and parameter accounting behind the claim:
*“8 GPU server… which 8 exactly?”and“1T-A1B?”*The technical concern is that throughput is not interpretable without knowing the exact GPU class, interconnect, serving stack, batch size, context length, and whether the1T

support to the official Gemma 4 chat template, matching an aftermarket template modification some users were already applying successfully. The change is framed as enabling better retention/use of model “thinking” traces in Gemma 4 chat formatting, though no benchmark numbers or implementation diff were provided in the thread.Commenters generally welcomed the official adoption and argued it validates prior community template hacks. Several users speculated that a largerGemma 4124B
MoE release would be needed to fully exploit the updated template for stronger agentic coding use cases.Commenters note that
Gemma 4’s official chat template appears to be addingpreserve_thinking
, a behavior some users had already enabled via aftermarket/custom template modifications and found effective. The main claimed technical benefit is improved continuity foragentic coding workflows, where retaining prior reasoning/thinking traces can help multi-step tool use and code iteration.One commenter cautions that the change may not be live yet: the
preserve_thinking
support is described as anopen PR that has not been merged, while the model files reportedly show no update for21 days
. This suggests users should verify the tokenizer/chat-template files in the actual model repository before assuming the new behavior is available in released artifacts.Several comments frame the template change as increasing demand for a larger
Gemma 4124B
MoE variant, arguing thatpreserve_thinking
would be more valuable when paired with a higher-capacity model for coding-agent use cases. The discussion is speculative, but technically centered on scaling the model size/MoE architecture to better exploit the updated chat-template behavior.

1. Claude Fable 5/Mythos 5 Release and Access Tiers
(Activity: 2698):Introducing Claude Fable 5Theimageis a benchmark comparison table for the post’s claimed Claude Fable 5 / Claude Mythos 5 release, showing the highlighted model leading or near-leading across agentic coding, knowledge work, spatial reasoning, tool use, legal, biology, cybersecurity, and health benchmarks versus Claude Mythos Preview, Claude Opus 4.8, GPT 5.5, and Gemini 3.1 Pro. The selftext frames Fable 5 and Mythos 5 as the same underlying “Mythos-class” model, with Fable 5 using safety fallbacks: cybersecurity, biology/chemistry, and distillation-related requests are routed to Claude Opus 4.8, reportedly affecting under5%
of sessions. Comments are mostly hype or skepticism rather than technical analysis, including jokes like “AGI confirmed” and a complaint asking whether “Fable [is] getting dumber recently.”One commenter noted an apparent access/pricing constraint:
Claude Fable 5 is free only untilJune 22
, after which users will reportedly need to purchase credits to continue using it. This is relevant for anyone evaluating the model because benchmark or workflow testing may need to be completed before the credit-gated period begins.
(Activity: 2387):Claude Fable 5 feels less like a model launch and more like a preview of AI inequalityThe post argues that Anthropic’s alleged Claude Fable 5 rollout represents a shift from a uniform public frontier-model release to a tiered access architecture: public paid users receive Fable 5 with safety routing that may downgrade requests involvingcyber
,bio
,chemistry
, ordistillation
to Opus 4.8, while selected partners purportedly get Mythos 5, described as the same underlying model with fewer safeguards. It also highlights pricing/capacity constraints: Fable 5 is said to be included in paid plans only untilJune 22
**, then potentially moved to usage credits, implying frontier-agent inference remains too expensive for flat-rate consumer subscriptions.*Comments split between concern over AI access inequality and acceptance of restrictive safety policies as necessary for high-risk capabilities. One commenter frames the outcome as predictable token-economics pressure toward expensive enterprise-grade models, while another defends a“rather safe than sorry”*approach despite user friction.Several commenters framed the launch as an expected economics shift: as frontier models grow in capability and complexity,
inference/token costs rise enough that top-tier models become enterprise-only tools rather than default consumer products. One commenter argued this will push everyday workloads toward cheaper local inference on hardware likeApple M-series chips orRTX Spark-class accelerators, reserving frontier APIs for high-value tasks.A pricing-focused thread claimed that the new model’s API economics make consumer subscriptions structurally mismatched with frontier usage:
“Our$200
monthly sub is like3
*API prompts with the new model.”*The implied technical point is that even high-end consumer plans may be viable only through heavy rate limits, model routing, or fallback to cheaper models such asOpus 4.8, which one commenter described as sufficient for “99%
” of users.
