Implements the Responses API endpoint that Codex CLI (and other modern OpenAI tooling) speaks instead of /v1/chat/completions. The wire format is documented in OpenAI's Responses API; this implementation has been iterated against the Codex CLI binary's SSE parser shape until no remaining schema gaps were found. Request parsing (parse_responses_request, parse_responses_input): - Accepts the typed input array (message, function_call, function_call_output, reasoning, custom_tool_call(_output), local_shell_call(_output), web_search_call(_output), tool_search_call(_output), image_generation_call(_output), compaction, context_compaction). - Maps hosted-tool history to function_call/function_call_output so prior actions survive across turns; rejects unknown item types and non-completed status with 400 to avoid silent context loss. - Strict content-array parsing: only string|null|array of recognized text blocks (input_text/output_text/text/summary_text/ reasoning_text); rejects non-text modalities (input_image/file/ audio) instead of accepting an empty prompt. - Merges adjacent function_call items into the preceding assistant message so text + tool-call turns render as a single assistant block. - Honors reasoning.effort (incl. "minimal"/"none") and gates reasoning summary surface on reasoning.summary opt-in. - Rejects previous_response_id, conversation, and forced tool_choice explicitly (constrained decoding / persisted state not supported). Output (responses_sse_*, responses_final_response): - Emits the full streaming lifecycle: response.created, output_item.added/.done, reasoning_summary_part.added/.done, reasoning_summary_text.delta/.done, content_part.added/.done, output_text.delta/.done, function_call_arguments.delta/.done, response.completed. - Branches the terminal event by finish reason: response.failed for errors and response.incomplete with reason "max_tokens" for length. - Every event carries sequence_number; every output_text part carries annotations:[]; function_call output_item.added ships with an empty arguments string (full args arrive via function_call_arguments.done and output_item.done), and item ids are stable across added/done. - Tracks whether </think> was actually observed so a truncated stream marks the reasoning item incomplete instead of "completed". - Recovers gracefully when the DSML tool parse fails after the model was suppressed at the tool marker: the suppressed tail is flushed as additional output_text deltas so the streamed message matches output_item.done. Tested by 25 rounds of /codex:adversarial-review against the same client this is meant to feed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Broaden the DS4 imatrix prompt dataset with provider-neutral agent/tool traffic, multi-language programming prompts, algorithm recall, Bash scripting, and multilingual translation tasks. Remove duplicate rendered prompts and avoid provider-specific client references in the generated calibration corpus. This improves calibration coverage without claiming to fix a distributed GGUF bug.
Fold the successful CUDA selector/top-k/indexed-attention changes into one clean commit. This excludes rejected experiment commits and the local prefill-slope work log.\n\nMeasured on GB10 with speed-bench/promessi_sposi.txt, 2048-token append chunks: 32K prefill improved from 255.61 tok/s on origin/main to 346.49 tok/s. Full-curve average improved from 316.39 tok/s to 369.76 tok/s. 32K full prompt + 128-token generation prefill improved from 312.87 tok/s to 368.43 tok/s, while generation stayed neutral at 12.49 -> 12.48 tok/s.\n\nCorrectness: make cuda-regression; ./ds4_test --logprob-vectors --tool-call-quality; ./ds4_test --server --metal-kernels.
Build score_official against the CUDA runtime on Linux and select the CUDA backend there, while keeping the existing Metal path on macOS.\n\nCorrectness: make -C gguf-tools quality-score; gguf-tools/quality-testing/score_official ds4flash.gguf /tmp/ds4_quality_smoke/manifest.tsv /tmp/ds4_quality_smoke/scores.tsv 16384.
Replace the default long-context continuation check with a deterministic prose-story retrieval test. The fixture embeds spelled-out person-number assignments in a long rendered prompt, and ds4_test now validates the generated Name=number list instead of brittle sampled prose.
Preserve Responses namespace metadata and tool_search calls while rendering DSML-safe internal tool names. Replay function_call, hosted tool, and tool_search_output items into the shared chat/tool path so Codex and Pi can round-trip tool calls without losing KV-cache prefix reuse. Document the /v1/responses endpoint and add server unit coverage for namespace, tool_search, and replay output shapes.
This reverts commit 2a7a5f3. There was no ack from the user. Don't want to take a fix that is astronautically produced from an unclear error trace.
Project sampled DSML tool calls to Anthropic SSE tool_use blocks while keeping raw DSML as the parser/cache source of truth. Reuse streamed tool ids for final parsed calls so tool_result continuation still matches live state.
Keep normal CUDA context buffers on device allocations, but route very large KV-cache tensors through managed memory so million-token contexts do not starve unified-memory systems during graph/session allocation. The fallback is scoped to the long-lived KV/cache tensors and logs when it is used because it may reduce performance. Tested on 0.180 with: - make cpu - make -B cuda-spark - make cuda-regression - ./ds4_test --server --metal-kernels - ./ds4_test --logprob-vectors --tool-call-quality - ds4-bench ctx-alloc 32768, 250000, and 1000000 - ds4-server --ctx 1000000 startup smoke (cherry picked from commit 0b248a65c07d21f2fc8ff4815bd8b75af26719f9)
Parse Anthropic tool_use blocks by their own type field instead of relying on the enclosing message role being parsed first. Some clients serialize messages as content-before-role, which made full-history tool_result replays look like unknown live-only continuations. Fixes antirez#127.
Return a 400 error with error type "context_exceeded" when prompt tokens exceed
context size. The response includes both n_prompt_tokens and n_ctx fields so
clients can determine exactly why the request failed and how far over the limit
they went.
Error response format:
{
"error": {
"message": "Prompt tokens (N) exceeds context size (M)",
"type": "context_exceeded",
"n_prompt_tokens": N,
"n_ctx": M
}
}

Thanks @fry69 , the PR you mentioned does not have the indexer for rocm platform (unless I misread it) - which is essential for the long context runs. |
I'd recommend to shorten the subject line to highlight what is important if "rebase to main" is not. |

thanks @fry69, let's keep it the way it is. |

If your PR subject starts with "rocm - rebased on top of the current main branch" expect people to read that and comment on that. |

this PR (next iteration over the #180)
the last change changes the order of reduction (sum) from well-defined (in cuda, from small to large I assume), to not well defined - to mitigate this I disabled fast math options at the rocm build path.
I will reenable these options later after implementing proper version of the optimised kernel.
All tests passed. The evaluation and agent flows feel comparable to the baseline.
I cannot see any obvious problems.
Probably it should not be merged to the upstream until the issues above are resolved (i.e deterministic kernel + minimal changes to the vanilla ds4_cuda.cu code etc).
However, it increases generation throughput from ~8 t/s to ~11 t/s on gfx1151, so I decided to share it with the community.
