feat(model_info): provider-scoped fill_missing_for_providers backfill from fallback generalization rules by devin-ai-integration[bot] · Pull Request #41093 · BerriAI/litellm

devin-ai-integration · 2026-09-14T16:22:56Z

TLDR

Problem this solves:

Fallback generalization rules only apply when a model has no cost map entry
A mapped entry missing a field (e.g. supports_reasoning) never gets it from a rule
Blanket backfill would regress wandb and Claude numeric-limit guesses onto mapped models

How it solves it:

New per-rule field fill_missing_for_providers: [..] on capability rules
After an exact entry resolves, rules listing the entry's litellm_provider fill only the keys it lacks
Entry values always win on conflict; unmapped-model behavior is unchanged
Backfill only applies to chat/responses entries and never writes litellm_provider
Claude adaptive/mid-conversation regexes no longer read claude-opus-41 as major 41
openai-reasoning-family-baseline fills openai, azure and azure_ai entries (the hosts that carry gpt-5 / o-series ids)
The version gated Claude thinking rules fill anthropic, azure_ai, bedrock, bedrock_converse and vertex_ai-anthropic_models entries (the hosts that carry Claude ids)
together_ai and fireworks_ai only host gpt-oss, and the bedrock gpt-5.x entries already set supports_reasoning, so those hosts are left out of the openai rule
wandb-reasoning-baseline, claude-family-baseline (limits), claude-always-on-thinking and routing rules stay off
The matchers return Mapping[str, object] | None, and fallback_generalizations.py now gets its logger via logging.getLogger("LiteLLM") instead of importing litellm._logging, so the leaf module imports neither the litellm package nor types (which CodeQL mis-resolves to litellm/proxy/management_endpoints/types.py)

This is #40941 (which targeted litellm_internal_staging and was closed) rebased onto main, plus provider scoping so the openai rule no longer touches chatgpt, copilot, openrouter, perplexity, gmi, replicate or vercel entries that merely look like OpenAI reasoning ids

User Flow

Before: a developer calling a newly synced openai gpt-5.x entry that lacks supports_reasoning has the reasoning param dropped

They call litellm.supports_reasoning("gpt-5.x", custom_llm_provider="openai") and get False
They send reasoning_effort="high" for that model and the param is dropped as unsupported

After: the same lookup reports reasoning support, so the param goes through

They call litellm.supports_reasoning("gpt-5.x", custom_llm_provider="openai") and get True
They send reasoning_effort="high" and it is forwarded
The same id under openrouter, copilot, perplexity, etc. and a mapped wandb model still resolve exactly as their entries say

Relevant issues

Pre-Submission checklist

Please complete all items before asking a LiteLLM maintainer to review your PR

I have added meaningful tests
The handful of test files covering my change pass locally, e.g. uv run pytest tests/test_litellm/<your_test_file>.py -v. Leave the suites (make test-unit-*, make test-unit) to CI: it finishes in ~15 minutes where a laptop takes an hour or more
My PR passes all required CI/CD checks (e.g., lint, schema.d.ts sync check, etc.)
My PR's scope is as isolated as possible; it only solves 1 specific problem
I have received a Greptile Confidence Score of at least 4/5 before requesting a maintainer review (Greptile reviews automatically once the PR is opened; only comment @greptileai to re-request a review after pushing changes)

Screenshots / Proof of Fix

Live proxy on localhost:4000 hitting real providers, same config on both sides. To emulate an entry the hosted map gains after a release (the case this PR is for), the five test ids were removed from the served cost map and from the bundled litellm/model_prices_and_context_window_backup.json on both checkouts for the duration of the run, then restored (git checkout -- litellm/model_prices_and_context_window_backup.json, both trees clean)

Native anthropic/ is not curled here: the azure_ai and vertex_ai legs below send the same Anthropic Messages payload through the same transformation, so they cover the adaptive thinking switch

Config aliases: openai-gpt-5.5 (openai/gpt-5.5), azure-ai-opus-4-8 (azure_ai/claude-opus-4-8), bedrock-invoke-opus-4-8 (bedrock/global.anthropic.claude-opus-4-8), bedrock-converse-opus-4-8 (bedrock/converse/global.anthropic.claude-opus-4-8), vertex-opus-4-8 (vertex_ai/claude-opus-4-8)

Notes on the openai rule's provider list

bedrock_converse and bedrock_mantle now carry gpt-5.x ids, but every one already sets supports_reasoning: true, so there is nothing to fill and they are not in the rule. Checked live on the PR tip with the unmodified map that reasoning params work there anyway: bedrock/converse/global.openai.gpt-5.6-sol with "reasoning_effort":"high" and "low" returned HTTP 200 and 391, sending "additionalModelRequestFields": {"reasoning": {"effort": "high"}} (resp. "low"), and bedrock_mantle/openai.gpt-5.6-sol over /v1/responses with "reasoning":{"effort":"high"} returned HTTP 200, sending 'reasoning': {'effort': 'high'}

together_ai and fireworks_ai do not host gpt-5.x (their /models lists only openai/gpt-oss-*), so they stay out. No azure/ OpenAI reasoning deployment was available, so that host was not curled; the six mapped azure/{eu,us}/o1-* entries that gain supports_reasoning: true were verified through get_model_info only

Diffing get_model_info output over all mapped entries at the merge base and the PR tip: exactly 6 entries change, azure/{eu,us}/o1-2024-12-17, o1-mini-2024-09-12 and o1-preview-2024-09-12 gain supports_reasoning: true. Every other openai, azure_ai, anthropic, bedrock and vertex entry the rules match already carries the fields, so the backfill otherwise only kicks in for future synced entries that lack them

Type

🆕 New Feature

Caveats (if any)

Medium

Backfill is keyed on the exact entry's litellm_provider, so a reseller entry (openrouter, perplexity, copilot, gmi, replicate, vercel, databricks, ...) lacking the field stays as is until it is listed in the rule or the sync writes the field
The six azure o1 entries above now report supports_reasoning: true, which is correct for o1 but is a visible change for azure callers
Two-digit Claude majors (10+) no longer match the adaptive/mid-conversation rules; the regex will need revisiting when Anthropic ships one

Low

CodeQL flagged imports of fallback_generalizations as module-level cyclic imports, first via litellm._logging -> litellm -> litellm.utils, then via types (resolved to the proxy module of the same name). Both imports are gone from fallback_generalizations.py; the logger is the same logging.getLogger("LiteLLM") object _logging.py exposes as verbose_logger
Backfill adds one pass over the flagged rules per uncached exact lookup, same cost as the existing unmapped-model path
The raw-JSON schema tests in the sync PRs still read entries directly, so bare synced entries need the field written by the sync

Greptile Summary

This PR adds provider-scoped capability backfilling for exact model-map entries while preserving explicit entry values and existing unmapped-model behavior

Adds validated fill_missing_for_providers rule metadata and matching support
Applies missing capability fields only to chat and Responses entries from approved providers
Scopes OpenAI and Claude rules to their intended provider catalogs
Tightens Claude version matching to avoid interpreting claude-opus-41 as major version 41
Adds regression coverage for provider isolation, field precedence, malformed rules, modes, and shipped model behavior

Confidence Score: 5/5

The PR appears safe to merge, with no outstanding correctness or repository-rule issues

Provider-scoped backfill preserves exact model metadata, excludes unapproved providers and non-text modes, and retains existing fallback behavior. The previous typing thread was manually resolved, and the current annotations address its concern

Important Files Changed

Filename	Overview
litellm/litellm_core_utils/fallback_generalizations.py	Adds validated provider-scoped compilation and matching for missing capability fields
litellm/utils.py	Merges matched capability defaults into eligible exact model entries without overriding existing metadata
model_prices_and_context_window.json	Enables scoped backfill for selected OpenAI and Claude capability rules and tightens Claude regex boundaries
litellm/model_prices_and_context_window_backup.json	Mirrors the fallback-rule changes in the backup model registry
tests/test_litellm/litellm_core_utils/test_fallback_generalizations.py	Covers provider opt-in, precedence, malformed metadata, mode restrictions, reseller isolation, and regex boundaries
