deprcate even more stuff, cut compute cost by 60%

[functionstackx]

agentx increased compute by 5x, this will cut it and only increase it by 1.6x vs. previous

Summary

InferenceX-e2e runs on a fixed, limited pool of GPUs and is maintained by a small team. Every scenario, precision, and recipe variant we keep alive burns cluster hours and maintainer attention that would otherwise go to new frontier models. This PR announces the deprecations that free that capacity.

Docs-only change to MODELS.md, mirrored in MODELS_zh.md. No config, recipe, or perf-changelog.yaml changes — the actual config removals land in follow-up PRs on/after the dates below.

Effective Monday, August 3, 2026

Scenario and precision retirements

Model	Deprecated	Remains
MiniMax-M3 (minimaxm3)	Single-turn 8k1k	Agentic coding
Kimi-K2.5/2.6/2.7-Code (kimik2.5)	Agentic coding	Single-turn 8k1k, until 2026-08-06
Qwen3.5-397B-A17B (qwen3.5)	All bf16 recipes, every scenario, NVIDIA and AMD	fp8 and fp4 recipes

Speculative-decoding A/B retirements — the spec-decode arm is the better Pareto frontier in every pair, so we stop running the non-spec-decode arm and publish only the spec-decode arm:

Model	Deprecated arm	Published arm
DeepSeek-V4-Pro 1.6T (dsv4)	Agentic coding, non-MTP	Agentic coding, MTP
Qwen3.5-397B-A17B (qwen3.5)	Agentic coding, non-MTP	Agentic coding, MTP
MiniMax-M3 (minimaxm3)	Agentic coding, non-EAGLE3	Agentic coding, EAGLE3
GLM-5.2 (glm5.2)	Agentic coding, non-MTP	Agentic coding, MTP
Kimi-K3 (kimik3)	Agentic coding, non-DSpark — from day 0	Agentic coding, DSpark

Policy change

Going forward we no longer benchmark non-spec-decode versus spec-decode as an A/B.

The non-spec-decode arm existed as a neutral baseline back when acceptance length was whatever a submitter's draft head happened to achieve, which made spec-decode numbers incomparable across submissions. That is now solved. golden_al_distribution/ commits one golden acceptance-length curve per model, thinking mode, and draft length, measured on the SPEED-Bench coding category, and AgentX pins every submission to that curve through synthetic acceptance:

• vLLM — synthetic_acceptance_length
• SGLang — SGLANG_SIMULATE_ACC_LEN
• TensorRT-LLM — TLLM_SPEC_DECODE_FORCE_NUM_ACCEPTED_TOKENS
• etc.

With a fair, engine-independent acceptance target in place, spec-decode results are directly comparable on their own and a separate non-spec-decode track is redundant. Agentic coding recipes are therefore run and published with speculative decoding enabled only — MTP, EAGLE/EAGLE3, DSpark, or whatever draft method the model ships. New models are onboarded that way from day 0, as Kimi-K3 is.

Knock-on effect worth flagging

kimik2.5 loses Agentic coding on 2026-08-03 and Single-turn 8k1k on 2026-08-06 (already announced in #2263-era notice). That leaves it with no active scenario — the model is fully retired after 2026-08-06. The existing 8k1k notice justified itself with "the Agentic coding scenario already covers them", which stops being true on 08-03; that rationale has been rewritten accordingly. Its configs should be archived under configs/deprecated/ in the follow-up.

Test plan

• Docs-only; [skip-sweep] in the head commit so no benchmark setup runs
• MODELS.md and MODELS_zh.md verified structurally identical — same headings at the same line numbers, same table row counts
• All model prefixes, recipe variants, and spec-decode arms cross-checked against configs/nvidia-master.yaml and configs/amd-master.yaml

中文说明

InferenceX-e2e 运行在数量固定且有限的 GPU 资源池上，并由一支小型团队维护。每保留一个场景、精度或配方变体，都会占用集群机时与维护人力，而这些资源本可投入到新的前沿模型上。本 PR 公告为释放这部分产能而执行的弃用。

仅改动文档 MODELS.md，并同步镜像至 MODELS_zh.md。未改动任何配置、配方或 perf-changelog.yaml —— 实际的配置移除将在下述日期当天或之后的后续 PR 中完成。

自 2026 年 8 月 3 日（星期一）起生效

场景与精度下线

模型	弃用内容	保留内容
MiniMax-M3（minimaxm3）	单轮 8k1k	智能体编码
Kimi-K2.5/2.6/2.7-Code（kimik2.5）	智能体编码	单轮 8k1k，保留至 2026-08-06
Qwen3.5-397B-A17B（qwen3.5）	全部 bf16 配方，涵盖所有场景，NVIDIA 与 AMD 平台均在内	fp8 与 fp4 配方

投机解码 A/B 对照下线 —— 每组对照中启用投机解码的分支都处于更优的帕累托前沿，因此停止运行非投机解码分支，仅发布投机解码分支：

模型	弃用分支	发布分支
DeepSeek-V4-Pro 1.6T（dsv4）	智能体编码，非 MTP	智能体编码，MTP
Qwen3.5-397B-A17B（qwen3.5）	智能体编码，非 MTP	智能体编码，MTP
MiniMax-M3（minimaxm3）	智能体编码，非 EAGLE3	智能体编码，EAGLE3
GLM-5.2（glm5.2）	智能体编码，非 MTP	智能体编码，MTP
Kimi-K3（kimik3）	智能体编码，非 DSpark —— 自第 0 天起	智能体编码，DSpark

方针变更

今后不再以 A/B 对照的方式基准测试「非投机解码 vs 投机解码」。

当初保留非投机解码分支，是把它当作中立基线：那时接受长度（AL）完全取决于提交方草稿头（draft head）的实际水平，导致各家投机解码数据之间无法横向比较。这一问题现已解决。golden_al_distribution/ 为每个模型、thinking 模式与草稿长度各提交了一条黄金 AL 曲线，均在 SPEED-Bench coding 类别上测得；AgentX 通过合成接受（synthetic acceptance）将所有提交锁定到该曲线：

• vLLM —— synthetic_acceptance_length
• SGLang —— SGLANG_SIMULATE_ACC_LEN
• TensorRT-LLM —— TLLM_SPEC_DECODE_FORCE_NUM_ACCEPTED_TOKENS
• 等等

既然已有公平且与引擎无关的接受目标，投机解码结果本身即可直接横向比较，单独保留一条非投机解码赛道已属冗余。因此，智能体编码配方一律仅在启用投机解码的条件下运行与发布 —— 具体为 MTP、EAGLE/EAGLE3、DSpark，或该模型自带的任何草稿方法。新模型自第 0 天起即按此方式接入，Kimi-K3 即为一例。

需要特别提示的连带影响

kimik2.5 将于 2026-08-03 失去智能体编码场景，并于 2026-08-06 失去单轮 8k1k 场景（后者此前已公告）。这将使其不再有任何启用场景 —— 该模型将于 2026-08-06 后完全退役。原 8k1k 弃用公告的理由是「智能体编码场景已覆盖这些模型」，该理由自 08-03 起不再成立，因此已相应改写。其配置应在后续 PR 中归档至 configs/deprecated/。

测试计划

• 仅文档改动；头部提交含 [skip-sweep]，不触发基准测试环境搭建
• 已核验 MODELS.md 与 MODELS_zh.md 结构完全一致 —— 标题所在行号相同，表格行数相同
• 所有模型前缀、配方变体与投机解码分支均已与 configs/nvidia-master.yaml、configs/amd-master.yaml 交叉核对

🟡 The spec-decode A/B retirement table and matrix rows claim 'published' arms (Kimi-K3 DSpark; MiniMax-M3/Qwen3.5 agentic-MTP) that don't exist in configs/nvidia-master.yaml or configs/amd-master.yaml — for kimik3 both existing recipes are non-DSpark (companion PR #2391 shipped it non-DSpark because DSpark 'doesn't work with Pipeline yet'), and for minimaxm3/qwen3.5 all agentic-coding recipes have no spec-decoding field (their only -mtp variants are under the single-turn 8k1k scenario). This is a pre-existing documentation gap made worse by this PR: after 2026-08-03 these three rows will point to scenarios with no backing config, contradicting the PR's own test-plan claim that arms were cross-checked against the master configs. Recommend either dropping these three rows from the retirement table until the DSpark/MTP-agentic configs actually land, or rewording them as forward-looking intent rather than an active 'published arm'.

Extended reasoning...

The PR adds a "Speculative-decoding A/B retirements" table (MODELS.md L21-30, mirrored in MODELS_zh.md) plus corresponding matrix rows for kimik3 (L52), minimaxm3 (L54), and qwen3.5 (L59) that name a "Published arm" going forward: DSpark for Kimi-K3, and "Agentic coding, MTP" for MiniMax-M3 and Qwen3.5. None of these three published arms currently exist in configs/nvidia-master.yaml or configs/amd-master.yaml.

For kimik3: the only two recipes in nvidia-master.yaml are kimik3-fp4-b300-vllm-agentic (no spec-decoding field, defaults to none) and kimik3-fp4-b200-dynamo-vllm-agentic (explicit spec-decoding: none). There is no DSpark spec-decode config anywhere in either master file — the only "DSpark" string in the whole configs tree is an unrelated architecture comment about the vLLM plugin's MLA/KDA attention kernels. The companion PR #2391 (merged immediately before this one, commit 0decc69) shipped kimik3 non-DSpark specifically because "it doesn't work with Pipeline yet," with the DSpark work explicitly deferred to a follow-up. So this PR's own docs mark the only currently-runnable kimik3 arm as "deprecated from day 0" and mark the nonexistent arm as "Active"/"Published."

For minimaxm3 and qwen3.5: every agentic-coding recipe in both master configs (minimaxm3-fp8-{h100,h200}-vllm-agentic, amd -mi300x/-mi325x/-mi355x-vllm-agentic; qwen3.5-fp8-{b200,b300-hicache,h100}-sglang-agentic, amd -mi355x-sglang-agentic{,-hicache}) has no spec-decoding field. Their only -mtp recipe variants (e.g. minimaxm3-fp8-b200-vllm-mtp, qwen3.5-fp8-b200-sglang-mtp) live under the single-turn 8k1k scenario, not agentic-coding. A grep for agentic.*mtp across both master files returns only dsv4 and kimik2.5 — confirming dsv4's claimed arm in the same table is real, but minimaxm3/qwen3.5's is not.

The PR's own test plan states "All model prefixes, recipe variants, and spec-decode arms cross-checked against configs/nvidia-master.yaml and configs/amd-master.yaml" — this claim doesn't hold for these three rows. Concretely: (1) grep configs/nvidia-master.yaml and configs/amd-master.yaml for kimik3 → 2 hits, both spec-decoding: none or field-absent-defaults-to-none; (2) grep for dspark (case-insensitive) anywhere in the configs tree → 1 hit, a comment about attention kernels, not a spec-decode value; (3) grep agentic.*mtp across both files → only dsv4-* and kimik2.5-* keys, never minimaxm3-* or qwen3.5-*. Since this is a docs-only PR with [skip-sweep], nothing breaks at runtime today, but after 2026-08-03 the matrix would present an "active" scenario for three models backed by no config at all, which is exactly the kind of drift MODELS.md exists to prevent.

Fix: either don't table these as "published arm" until the follow-up PRs land the actual DSpark/agentic-MTP configs (kimik3's follow-up is already flagged as pending in #2391; minimaxm3/qwen3.5 would need new agentic+spec-decode recipes added first), or reword these three rows to state the intent to only publish spec-decode arms going forward rather than asserting a currently-existing "published arm."
